Mazdaspeed 3 Blows Engine On The Dyno After Making 400 WHP
HTML-код
- Опубликовано: 17 авг 2019
- Unfortunately we blew the stock engine in the Mazdaspeed 3 on the dyno. All the tuning was done by me, and many would agree that it was not overly aggressive. It's hard to say what caused the failure at this point, but we noticed knock retard values above 5 degrees in the data log right before it let go. This didn't really make sense as we were running 94 octane pump gas mixed with 3 gallons of in tank methanol. The next possibility in our minds, is that using the WOT box as a rev limiter while making this much power and generating this much heat with back to back runs, might have stressed the engines stock internals to a point of no return. We already know that the OEM pistons and connecting rods are the weak points of this engine. At this point we've sourced another used CX7 long block and are going get it built with forged connecting rods, pistons, upgraded bearings, and possibly some head work. Enjoy the video!

Dam that sucks, on the bright side definitely more content for the channel. Just hate to see it happen this way.
Oh my god my heart broke when that happened.
So did mine! Followed by a deep realization of "time to build" lol
Hope you get it back on the road soon mate. That's just savage. Great channel
Damn!! It's been a fun ride with the white speed 3.. sorry to hear, but also looking forward to seeing you guys tear it down and rebuilding.
Sad to see the beast blow on the Dyno. I've got a BL MPS that I blew the stock engine on, built it and loving it. Good luck with the build!
Thanks a lot! Wasn't expecting it to blow, but then again, do we ever?
Solid 400WHP with torque kept low and safe. Still it blew, that's unfortunate. Keep it strong mate, hope to see more videos on rebuilt process.
Thanks man ;)
And I'm over here complaining about fuel pressure issues. All the best man!
Buggery, that sucks. I feel yer pain, I've been there 3 times, blown engines suck (not my 2008 Mazdaspeed3 yet). Never on a dyno either, always far from home!!!
Would be interesting to see what went wrong as it seemed to be a hauntingly similar situation like Low Speed Pre-Ignition. Lex did a good write up about it on the forum. I used to work with him many years ago (before Stratified Automotive Controls) and can't even begin tell you how super detailed he is with the work he does. I remember him bringing in a bent rod (piston still attached) to work back in 2009 as he was trying to figure out what was going on with these engines. I used to do engine teardown/machining/building and the part he brought in was quite mysterious as it didn't have any of the witness marks associated with known failure analysis, anyways, I could see that he couldn't let this slide by. So maybe a chat with him about the tune could shed some light?
Oh, I also feel your pain on the cost as I live near Vancouver, we Canadians pay 30-40% more for this hobby as the US has all the good stuff.
Good luck to you.
I turboed my Mazda 3 hatchback with the 2.3 na engine and running 8lbs boost with no time currently I see you actually got another block so I'll just build my second block and swap engines when fully built internals, I've been watching your videos alot lately as I was installing the turbo on my car after the engine is built in going to add the meth then go for a bigger turbo
Yeah not in the 2.3 i have an upgraded hatch speed3 even with a timing chain its still far too weak to handle that much turbo even 8 seems far out. 10? No way it wont hold and thats too big a risk on those 2.3 Ford engines. Okay fine it holds 10 lbs and ratios are all solid for awhile but then transmission could act up too much forced induction is just way too stressful and you WILL blow up the motor. WWSKD? (What Would Scotty Kilmer Do) Not this i can assure you 100% and wouldnt advise anyone.
Damn this really sucks! I've been following your channel for a long time now watching and learning from your builds for when I finally do my MS3. How many miles were on your stock block at this time? You were making great power and it was nice seeing the runs back to back with the slight changes you made. Hopefully you get her back on the road soon with that built engine.
It had 154,000 kms (96,000 miles). Thanks man. We had about 10-15 minutes in between runs, but only 5 minutes between the 400 hp run, and the verification run when it blew. Can't wait to get built !
I know how much stress this is. But you should really document all your repairs and the build. I will be following along watching you!
That's the plan!
I sorry to see you blew the motor now. It’s time to do some reach and build a beast of a motor. I hope nothing but the best for your future motor build
Thanks! We appreciate that
Worst feeling ever I'm sure.. but I cant wait see the process of building it 🤙🏽
Dang that was crazy!!! Good HP though!
All the best with fixing the car, GL.
Sorry for that, but its a new start, I'm stay here for see the progress guys
Dude it’s all good ! You took it pretty cool I was sooo piss when I blew mines ! Now watch this mazdaspeed Reach to the next level
I'm just lucky I have another car to drive
Lol my parents wanted to kill me ... I had no car for 6 months! ...
@@RedClutch22_ Oh man, it's crazy how we don't realize what we have until it's gone
Dude Facts bro
You can tell when the car was going into Boost the motor just took a Shit ... no fucks given ... you would think at high RPM it will blow at that moment but “GOING into boost” damn
Just thought I'd point out there probably wasn't much wrong except the stock internals only hold around 370hp at the wheels "safely". Looking forward to following your build!
Yeah and even with a conservative torque curve, anything can happen
How long did she last after the timing chain was done I’ve been fallowing your Chanel I’ve got an 06 ms6 I just did timing chain motor mounts cork sport fuel line wheel bearing bov optima battery I take and access port I’m aiming for reliability over power tho god I hope that she lasts i hope u build a new motor would love details on where to get one just Incase
This made me cry.
Is the cx7 engine the exact same engine in our cars ? Btw Sorry to here what happen bro , your speed 3 was one of my favorite out there . I know you’ll come back stronger and faster lol!!!
Any update buddy? I feel bad for you. Don't know what i would do if that happen to my speed3. hope to see that speed3 up and running soon. i like all your videos, keep on the good job !
Thanks a lot man! Right now the spare engine has been torn down and is awaiting it's built destiny at the machine shop. Tbh I'm glad it happened here rather than on the street.
it never fun when it happen but like you said better on the dyno then in the middle of downtown traffic or on the highway. Glad to hear that the engine is at the shop will be waiting for more videos.
:( rest in peace little axela
What happened? I’m curious if the ring gap is just to small from factory on these for this kind of added power/boost
We have a disassembly video of the carnage. Basically cylinder 2 connecting rod failed :(
I watched your video yesterday and I was like dam that sucks. Now on my way to work today I got rod knock bad. I’m in the same boat you are now
At least you can salvage the block!
Yeh. It could of been worse
@@jeffreygonzalez8544 100%
I really really like your MPS. Keep us posted on the aftermath and perhaps what failed ? Thx
For sure!
Jeeze man, it’s “never enough”
Damn all good hope you find a good deal on a block and do some diy on porting the heads and 80lb springs. If you build it yourself it's very cheap I have a thread on mso but i did before mine blew so price may vary a bit block+machine shop
I feel your pain man. Mine blew 3 years ago.... :(
What did u end up doing?
How many kms were on your car when you installed the bnr s4? Do you think your engine would have lived longer if you stayed around 350-370 hp range along with torque? I’m about to install a bnr s4 on mine as well but I’m a paranoid fuck.
The car had about 120,000 kms on it when we installed the BNR S4. I had been tuning the car since then using virtual dyno to estimate power. I found that virtual dyno read lower than the actual dyno that we went to, so if we go off of actual dyno numbers in comparison to VD numbers, up until it blew up on the dyno at 160,000 kms, the car was probably making anywhere from 350-400 whp depending on what tune I was running and how cold it was outside. Some theories I have that caused the engine to blow are that we were doing too many back to back pulls, the wot box acting as an ignition cut rev limiter (rather than the ECU's fuel injector cut) may have stressed the rods, or it was just it's time to blow. It's hard to say when these stock engines will let go, but the best thing to do is run an alcohol mix to prevent detonation, and run a safe consistent tune (not to say I wasn't lol)
Don't worry going built motor is great.
Is not all about fuel air ratio... playing with timing to get more hp is always dangerous.
Life is full of lessons... repair and go for those 400 whp.
This definitely wasn't a result of the minor timing increases they did, the rods were probably stressed and gonna let go anyways. 12.5deg at redline is basically 93 octane levels of timing, nevermind the in-tank methanol.
Awesome stuff new sub for that
Lol all it took was for me to blow my engine
Sorry mate it happens at least u werent driving far from home like i was make more vids i will watch them
@@greentoolsnyc3985 Thanks dude, It could have been a lot worse. It worked out because I'm going built now so, should be fun!
400 whp is pushing the stock internals to its absolute limits dayum! I'm surprised it didn't happen before this dyno
Oh yeah it definitely had a good long run lol
400whp is surprisingly safe to run if you tune it right, i know people that daily 400whp stock motor cars, even one who’s managed to make 500whp on an unopened engine last quite a while
I'm a simple man, I see a speed 3 I hit subscribe. But I see neetronics I then hit the like button
Howmuch was it at the crank I only as cause a buddy of mine just brought one completely stock an broke his cv doing launches his butt dyno he told me was about 400nat the wheel but tis completely stock one cat has been removed an that's with a busted cv so I'm fallen it be from my buddy that is , be interesting to find out as his gauge only once read 18 but digital outputs from the obd2 onto my phone was only like 12-14ish psi would drop off above 6500rpm so it's fair to say tis was only about 250ish right? I recorded all of it on my phone an it had funky timing advancing never below 6.5 positive advance on the timing but it would spike up an down rapidly lol an he said he only uses half throttle but I was with him that sh3t was foot flat befor quarter throttle lmfao this just proves it man
If he's completely stock he won't be making more than 240 whp, but then again, numbers can vary. The only way to really know what his car is putting down at the wheels is to take the car to a dyno, and even then, all dyno's read differently
love them gen1. i have one also but i keep on getting misfire, rough idle and constantly dealing with crankshaft sensor. i replaced it but a week later it gives me the code again. any advice brother?
Try swapping coil packs to see if the misfire transfers to another cylinder. Also check crank sensor connections and related wiring for damage or shorts.
@@WannabeTuners the dealer swapped the motor with another replacemt and the fixed all the problems but i keep getting the same symptoms. i changed the coil packs so im thinking its the wires. i replace the maf sensor already also and spark plugs. 113k miles 😭
Is there a while thing of not flooring it under 3k? Maybe tomucg torque, idk just a guess from what i heard at a local meet i went too
When tuning you want to start a pull anywhere from 2500-3000 rpm to dial in as much of the usable powerband as possible. In the early days it wasn't recommended to floor it below 3000 rpm in 6th gear due to more load on the engine for a longer period of time. Nowadays the do's and dont's have been figured out, and the ability to tune the ecu to limit torque output below 3000 rpm has greatly helped to reduce engine failures. That being said, running a safe tune, with quality fuel is the most important thing. Personally whenever I am in 6th gear, I never floor it below 3k rpm ;)
@@WannabeTuners I dont wot below 3k at any gears...
How much power did it make at the crank?
If we look at what it made at the wheels, we can add about 10-15%
So sorry man. That sucks, kinda sounded like you windowed your block by sending a rod.
I’ve had bolt installed on the past on my speed3 and it was fun but now I have my speed6 I’m going the different route spend the money on a built long block that supports the hp I need
Yea and pack a fire extinguisher just in case
Oh no...:( Well, too many consecutive runs. I'm pretty sure that what happened is the classic phenomenon of piston rings butting and piston jamming against the cylinder wall. Happened to one of my friends I was tuning for. In his case it was #1 but it's really a matter of which cylinder has the smallest ring end gap for the heat already in the piston/cylinder.
The good news is that with a built engine and the same mods you have now ( +WMI, never leave WMI out of the game) you can shoot for 600 (even though on a street used MS3 the practically usable limit is about 500bhp and 500-520lb*ft).
P.S.: if you were spraying (WMI) this wouldn't have happened.
Why was the timing increased when you weren't making any large gains until it blew at 12.5?
According to the dyno graphs, from 9.5 to 12.5 degrees at 6700 rpm, it was generating about 10 whp more per degree at the same boost pressure!
hey i just picked up a speed3 im from hamilton area what kinda km did yours have when she poped
It had just under 160,000 km's
@@WannabeTuners dang mines got 376xxx
The cx7 turbo engine and the heads are the same as the mazdaspeed 3 1st Gen?
Yep the cx7 engines are the same in the gen 1's
@@WannabeTuners so that mean if my car is moddded, and I blew my engine off, I just bought a used cx7 turbo engine and swap it and thats it?
@@ivanborruel Well the turbo in the cx7 is slightly smaller, so you'd want to swap over the turbo from the speed 3. You'll also need to swap over the flywheel and clutch onto the cx7 engine by removing the flex plate and install a pilot bearing into the crankshaft.
Get one of those corksport built crate engines, they already have everything done for you for 500 plus, I have the same car with the same color so this was hard to watch
Thanks man, although I'm picking up a used running cx7 long block tomorrow which will be getting the treatment ;)
Its probally nothing you did.. with big turbo its not if but when!!!! Just curious why meth in tank when you ran aux fuel. Why not just e-85 mix??
Because we don't have E85 in the area
Lul E85 is a pump gas where i live
Ugh so sad. Hurts i have the 04 speed3 1st gen upgraded and would still have my heart sink seeing that. Yeah way too much stress on the engine. Stock engine cant handle that much piston and connecting rod or even just getting a small nut dislodging inside the engine. Definitely will need love and care. - ASE Firestone mechanic.
Don't u mean 2007 and up? Yeah man it was bound to happen sooner or later. Packing a fire extinguisher in the car from now on!
Can yall film the engine building process.
Absolutely!
Hey, stock engine in Germany dies ~350hp at 20.xxx, direct or over time. Due to the high speed interstates we can see where the durability is.
Good to know thanks!
are you ever going to get this back together?
Yes sir it's back up an running now, just need to finish editing the build video :)
It felt those tires on the car and commited suicide. Good luck with the build and send me a DM if you want a hand pulling the motor or putting it back in. I've done it multiple times
Haha thanks man
I'd stop by to help too
Every speed owners nightmare
This was a hard watch, knowing it was going to blow. I do think though that meth mix in the fuel tank is a very bad idea. And very unpredictable. And I think this is why you ha e a massive knock event, and blow a rod out the side. Fit a meth kit buddy. Much safer. I run 436bhp on stock block with a devilsown progressive meth kit. So my boost air temps are kept in check. I run 99ron (or octain as you lot call it) with meth kicking in at 15psi, and has full spray at 20psi. Hope this helps for the future build buddy.
Thanks man!
Hey, the way I see it: Better this happens on the dyno than when you're out driving. That could be super dangerous if it happens during a street pull
For sure man! Packing a fire extinguisher from now on;)
What rpm was the tuner doing pulls from??
2500 rpm to 6700 rpm where the WOT box limits the revs through ignition cut, as opposed to the OEM fuel injector cut rev limiter
Stock blocks should really not do pulls under 3k
@@spillybuilt7491 All the tuners ask to go WOT after 2500 for the datalogs in 4th gear soo....
@@spillybuilt7491 That's what is recommend, but for tuning purposes most if not all tuners will start a dyno pull around 2500 rpm in order to tune that area of the rpm range
It was bound to happen at those power levels regardless. Best of luck on the rebuild!
No one noticed earlier the black smoke from the exhuast. Clear signs something is wrong. Just my mechanical experience. But you live and learn. You start modding and eventually this is the end result.
The black smoke is from the rich air fuel mixture and the blueish white smoke is from the turbo seal
@@WannabeTuners signs of tragedy about to happen.
Where are you located?
We're in the Toronto area
Another option you could go is a drop in ready long block from corksport or speed performance. I would go for stage 2 which supports 700++hp
Just slap all your parts and your good to go
That is an option too! I'm just not sure if getting it done locally would be less expensive or not
Wannabe Tuners it’s not cheap to build a motor but it’s not easy either that’s why you gotta go to the right ppl who have been doing it for long time and who knows these cars
Because you don’t want to have a built motor that wasn’t done right I’ve seen it happen
That's right better spend a bit more now that you re in this situation and get a safe reliable build than risk your money on a cheaper option
@@Mazdaspeedgarage Thanks for the advice :)
@@raquielcross5757 I know a reputable engine builder in the area called Competition Automotive. They've been around for over 40 years. I'll probably get an estimate from them first and go from there ;)
Not the results you want to see when you’ve spend your money 💰 on quality parts to achieve that satisfaction but keep your head up it could have been worse just means you gotta build your motor take your time with it do it right
And do it right the first time so that won’t happen again
Blow up is at 6:03
Well that fucking sucks I was wanting to turn up the boost myself but I’m thinking I’ll leave her at stage one for now
They always blow up, even starndard, what was mazda thinking?? They need stronger internals, then we are talking some serious power!
Soooo You found another rig; 2nd gen’?

@@WannabeTuners 💪👍👍
Mine has been making about 370 on e85 for about 6 years on the stock motor on a bnrs3 scary i run her hard to but I have always had this fear in the back of my mind .
That's great to hear, I too have been around the same power level for years, always tuning on the street with 2 gallons on in tank methanol. This was actually our first time at the dyno. I have a feeling that abusing the ignition cut rev limiter from the WOT box after almost every pull might have stretched the stock rod, causing it to sheer as soon as torque started increasing. When it let go at 4300 rpm, it was only generating 320 ft lbs of torque. This is all speculation though. It very well could have just been its time. Either way, I don't think we'll have any issues occasionally using the WOT box with the built engine :)
Sucks brother... mine just cracked a ringland. Didnt explode like yours... judging by yours you will have to find a decent long block and rebuild it. Prob hit the valvtrain when it went boom boom.
Yeah dude consider yourself lucky. Take it easy on it and build her asap. I've already sourced a used running CX7 engine ;)

@@WannabeTuners oh geez! I just had to throw a gen 2 transmission in mine. Picked one up with only 40k on it.

I not very experienced with MazdaSpeed3 engines but the Mustang Ecoboost 2.3L block shares some designs with the MazdaSpeed3 block aka the Mazda L engine
looking up similar Mazda Zoom Zoom Boom and the Ecoboom situation
putting aggressive boost levels combine with advance ignition timings is a recipe for disaster

it looks like there was knocking on the final run when the engine was really hot and it happened during the up stroke cycle and the con-rod/s just bent and snap under the high boost and detonation
the bent/broken rods basically hit the sides of the cylinder and blew that chunk of the block and the rest of the components
but def a engine tear down will reveal the damages and the cause of the failure.
This is my assumption at this point based on my past experiences with blown Evo 4G63
The engine did sounded funny on that last run,right before the motor blew
Oh What!?!?at only 350 torque??
I think maybe the car did too many runs in a row and needed to cool off before other triles..I m so sorry for you man that's a bummer now another load of money to rebuild it, atleast after that u d know you can easily pass 500 ponnies
Yeah man a build block is all this thing needs. I'm just looking to make decent jam reliably
Yeah I was wondering how long did he wait after each pull on it.
@@cliffordhaines6495 About 10-15 minutes in between runs. But only about 5 minutes between the 400 whp run and the vented block run lol. Definitely should have let it cool longer in between, but it goes to show that the block was ready to pop
Damn, that sucks man... Part out?? 😜
Nah, I'm just playing. Time for full build. Send it!
No way I'm parting this thing out. I love boost way to much!
Just watching this, that’s sucks. These engines are hit and miss when pushing the limits. Mine made 520whp before it let go on stock rods and pistons. Bows the time to build so you can go further safely
I noticed you guys were throwing more timing at it instead of boost. Is there a reason why? I know most tuners prefer to add boost vs timing as timing creates more heat which of course cyl 3 is always producing more than any other. That’s what let go on mine
@@TheOriginalPancakeHou5e Yeah man it should be good when she's built and ready for action. When I tune I always dial in my boost and fuel curve first, and increase timing last. It's pretty much a balancing act between timing and boost, and too much of either will put more stress on the engine in general. I didn't want to run too much boost as I didn't want to cause inefficiency in the engines ability to breathe. I feel it runs better at 22 psi instead of 24 psi with these upgraded manifolds. We hear of people pushing big power on stock blocks, but that does not come without risk. I'd consider someone making 520 whp on a stock bottom end for a while quite lucky lol
What caused it?
I'm not exactly sure what caused it, although I'm thinking that the WOT box's abrupt ignition cut rev limiter feature may have stretched or fractured the cylinder 2 connecting rod, causing to break as soon as mid range torque was generated. With the stock block and a bigger turbo, it's not if it will blow, but when :) It's better to build it while it's still in one piece so you don't have to pay for another engine.
I’m surprised after adding 3 degrees of timing the tuner still added another full degree... sorry it blew.
I was the tuner! It's all good man, there's always risk involved when making this much power with a stock block
Wannabe Tuners of course!! Always a risk. That’s name of the game! Excited to see it back up and running hopefully soon
@@SpiffyDay Absolutely! We picked up a used running cx7 long block not long ago. Let the fun begin!
The timing was really conservative, realistically most speeds can run another 5-6degrees of timing on an ethanol mixture before getting close to the knock threshold.
mine went out while coming home at night on the highway whole car was in flames and light the whole highway like it was day got stuck at 3k rpms like it was redlining i have no idea where rod 3 went

@@Ratcher. Haha alright man thanks for the advice;)
Damn after like the 4th time i was like shit that engine taking some abuse! Is that normally how a Dyno works?? i would think the shop has to have some responsibility here no? sorry this happened dude, i love the vids you guys did for the mk5.
Thanks brother! All the tuning was done by me, so the shop cannot be blamed
Dyno is the best way to tune and that is standard. Something else went wrong.
Also when you get tuned by a shop most times they make you sign a waiver. Meaning if they suck at tuning and blow your car up they arent held accountable. Its just to cover their ass.
Can anyone help me out with my boost problem?
I was hitting about 16 psi then 13 after about9 and at times I dont even feel the boost what should I check ?
Email us a data log of when it happens. Also check for any boost leaks.
@@WannabeTuners I put a smoke machine on it and didn't really see anything. Is there certain spots of the car I should check ?
@@emmanuelguerrero6598 Not really. It could be a lot of things. What mods do u have on the car?
Either a boost leak or injector seals
Y i k e s. With how everything has gone with my car I predict mine will blow the next time I drive it every single day. Not a fun way to own a car. It's known across the forums 400whp is the absolute max for stock internals, why keep pushing, just sheer curiosity?
Well the first pull we did made 378 whp. That same map made 340 whp in virtual dyno on the street with CF 1.01, so since I've been tuning my car on the street, it's possible that it's been making more power than I thought. The reason I kept going with it was because I've ran more ignition timing in the past when tuning on the street, but never this much boost. Usually 22 psi with 11 degrees at 6k rpm. So either it's a coincidence that it blew on the dyno and not the street, or that little bit more boost was a little too much, or hitting the rev limiter with back to back runs stressed the components beyond what they could handle. Tbh I'm happy it happened on the dyno and not the street! This forces me to build, and the last thing I want to do is sell the car!
@@WannabeTuners Yeah fair enough! Was probably a lot of things building up to the boom. Sure are lucky it happened there. Just curious but how much oil seeped into the dyno lol
@@ProChargedLS2 Ohhh there was a lot of oil that seeped into it. There was oil all under neath the vehicle. Hopefully oil doesn't damage their dyno.
RIP
Mine build was over 10k like 7 years ago I'm sure it's more now. Good luck
10k usd? What all was done?
10k? investment? or miles on car?
I highly doubt you paid 10k To build a 3 motor 😂😂😂 what ya goin for 1000 hp? 😂😂
10 for motor, exhaust,turbo kit,etc
@@fsflip3111 invested
Damn .. u guys run mad low timing compared to us in the KDM land
19-21* is around what most run
Some guys talk about 27-28* .. I’m like uhhh 😬
Oh that's pretty high, what is KDM?
Good god so hard to watch. When I went on dyno to see what power I made I was holding my breath each oull .. so many nightmsre stories about dynos and vids of blown up motors
Yeah I definitely didn't expect my first dyno experience to involve my engine blowing haha
Holy Jesus
Sell me that guardian angel. Lol
I'm definitely gonna need it when we drop a built engine into this thing ;)
Those jagged lines are showing possible misfires
Shouldn’t look like that
It's very possible, we did notice some abnormal knock values in some of the pulls
Hopefully I'm not next to ZZB. I'm just down the road from you guys, so I hope it's not contagious.
I really do wonder if the WOT box had something to do with it
@@WannabeTuners funny enough the guy I bought my sway bars off of ZZB at Neetronics as well. Only with a GTX3071 and a spike of 32ish psi. Made around 500 when it popped though (or so I was told), he was from Milton and also drove a white gen juan.
@@sbscars Oh damn what did he have done to the car? Stock block?
@@WannabeTuners Yep, stock block. Supporting mods from what I can remember were:
-Sure Motorsports turbo header (Which I bought off him)
-ATP Turbo GTX3071R externally gated to a 38mm or 44mm Tial (don't remember the exact size)
-3" catless turbo back
-TR8 FMIC w/ CX racing piping
-CPE injector seals
-Aux fueling w/ split second controller
-3.5" intake
-unsure what intake manifold he was using because it was already sold when i went to pick up the sway bars and turbo header.
His name was Imran if i remember correctly, his ad was on the facebook market place back in March 2019 when I met up with him. Super nice guy.
What what caused failure do you think?
I'm not exactly sure. I've never had issues one the street with a similar tune. The difference is that on the street I always shift before the WOT box's ignition cut type rev limiter. I wonder if the random cutting of the ignition system under high engine load at high rpm stresses the engine components enough to weaken them.
Damn, that’s shitty....watching all that hard work just to Grenade the engine makes me sad. Wishing for a speedy recovery of the Mazda.
@@jessebudelman Thanks man, she'll be back up and running with a built engine soon :)
Bitchin’! Can’t wait to see it. Makes me wanna find a low milage 2.0 ecoboost and build my own engine for my ST! Haha
@@jessebudelman Yeah man go for it!
These motors don’t like to hold more than 350ft lbs of torque. That was highly likely the failure point; the rodssss
That's exactly what happened, the cylinder 2 rod sheared causing some serious damage. We have a teardown video showing the carnage
No way! Nice rims tho.
Yeah I love my cheap (inexpensive) wheels
💰
is it just me or does the engine have a funny sound on the last run?
In the data log it was pulling over 5 degrees of timing for several cells right before it blew. We're not sure if it was just noise from a stressed component, or if it actually was detonating (which doesn't seem feasible as it was running 94 octane with 3 gallons of in tank methanol)
@@WannabeTuners could be due to the noise from a stressed component, keen to see what it looks like when u open it, i built my motor like 4 months ago and have to say u will enjoy doing it, stay positive and good luck bud!
@@btshader Thanks man! I take it u got everything machined at a shop, and then assembled it yourself?
That sounded like LSPI. Not uncommon in DI engines unfortunately.
@@byteoncomputerservices8054 It blew at 4300 rpm generating only 320 ft lbs of torque based on the dyno graph. It was running 94 octane with 3 gallons of in tank methanol, so pre ignition and detonation should not have been an issue. But, anything is possible. That dip in power that u could hear was over 5 degrees of timing being pulled right before it let go. Wether it was knocking, pre igniting, or just noisy from a stressed component, taking it apart should be pretty interesting, and hopefully we can get a clearer idea of how it failed :)
That car sounded unhealthy from the very first pull. They just have that weird sound when they are about to go in high rpm I've learned.
Oh no! 😕
Yeah man maybe I had a weak stocker blocker
Lost my job with a 12 month old to support. Went bankrupt do had to buy a car. 6000$ on a mazdaspeed 6 and didnt even last 1 day..
Why would you run it that many times only 10-15 minutes in between and then 5 minutes between the 400hp.... like dam... what a waste...
It's part of the game, better it happened here than on the street!
Nooo monicaaa..
Torque is what killed your block ... You guys should have called it a day after hitting 350wtq numbers ... You can't push these stock blocks on higher torque or this will happen ... And if this dyno-jet wasn't calibrated correctly and read lower , you were playing with fire without even knowing it
Dang, that stinks. Seeing the title, I was puckering during the vid, haha. This is the ZZB story you always fear - on the dyno during WOT. Amazingly, most ZZBs occur in casual, daily driving, not even during WOT. It looks like it let go around the peak torque rpm range too, but your numbers were easily in what's considered "safe" for stock-block range.
Mileage on the motor? How long at this power level? Something for sure wasn't right if you were getting 5.xx KR with the level of octane you had in light of the timing you were running. That KR points to maybe ringlands, bearings, or rods already having issues, perhaps, and this was just the last straw. Well, build it stronger and come back better than ever! XD
Thanks dude! It had about 158,000 km's on the clock. Based on the way I've been tuning it over the years and according to this dyno, it's been in the 340-380 whp range for about 40,000 km's since installing the BNR S4. Virtual Dyno read a little lower than this dyno. We read and hear a lot about how stock blocks can take quite a bit of abuse, and it's been proven time and time again that they can. But based on how fragile the stock rods and pistons look, I'm not surprised. We found time to take the blown engine apart just yesterday and will be uploading a teardown video very soon. The damage is pretty bad and it's hard to say what caused the failure, but hopefully someone can give us a better idea :) The machine shop should be starting work on our used CX7 long block in the next week or two, so it's just a matter of being patient and excited at the same time lol
