As soon as I heard that rattle my first thought was FLEX PLATE!!! AAAHHHH!!! 😂 You see this on Duramax engines as well. Albeit very rarely, but once you DO hear it, think the worst, and then realize you didn't blow a crank, you don't forget it 😂
Man, I get devastated for far lesser things. Don't know how you guys can keep your cool like that but glad you found it to be a way more minor issue than you thought. Love those power numbers you're putting up, and this thing is going to be sick!
So glad the engine wasn’t broken! Also I’m sure everyone is here for drag racing, but man you could make a serious road racer out of that. The IRS is choice.
Consider studs and nuts on the flex plate instead of bolts if this continues to be an issue. I dyno tested piston aircraft engines and the adapter hub we used would sometimes come loose on high HP engines. We switched to studs and nuts and never had that issue again.
I loved the addition of the real time oil pressure, fuel pressure, timing, etc it really helps you understand what the cars doing on the dyno and what different sounds might be correlated to
incredible! whew with the crank bolts. i like how that 8082 is working! seems like it spools up fast also, this thing really starting to make some nice noise up top
I wonder if a wedge lock washer would work in this situation? Your suggestion would most likely solve the issue though! Some good old red loctite fixes any loose bolt
Awesome hp numbers. I never realized that these engines could handle that much. I've seen the 3800s get some good numbers. Looking forward to seeing it on the track.
So cool. The straight six leaves plenty of room for that turbo, waste gate and the exhaust without getting the tubes too kinky. This looks to be working out well.
Crazy what good suspension and an automatic does at the drag strip. We were making around 1000whp and barely got in the 9s with a 9.96 @ 160 . In a 5 speed 4 door e36 328 back in 08. Did still have full interior, heated seats and ac.
Definitely a unique sound, I've actually bought two vehicles coming across The Auction Block that sounded like that and I bought them cheap because everybody thought they were going to have to put a motor in them
@doncruzen6246 That is for sure the best time to have the knowledge of these types of things. I got my current car at auction because people thought it was blown up because of all the oil it burned, but some idiot put close to 17 quarts of oil in it. It naturally aspirated, so it had to bad valve cover (weird pcv system design) or something stupid cause it had good compression.
Took a trip in the early 90's down the coast to Tampa from the north east and when we got close my buddies van was making rattling noises which we drove with for the last 100 miles or so figuring it was a rod knock and we better get to where we are going if we can make it. The next day I got under there to check it out and the flex plate had broken 4 out of the 5 connections between the 5 holes so basically was held together by about 2 inches of plate. Since we had nowhere to pull and engine in Tampa I shimmed the plate with zero lash and on the way back only had to re-tighten the bolts once in Virginia. Ahh the good ol days. :D
What seems to be so interesting is that the potential and universal acceptance this engine would have received had it been a world platform and been used in the classic way GM used engines like this in the non us market would have been developed and accepted well yet it was not Just imagine if Australia Europe Asia and Africa got them too instead of the asthmatic v6 platform It’s like they don’t want the straight to be used for a more capable tractable platform It’s clearly a capable competitor to any other inline platforms made by other companies the world over
Well, I have been watching the rise and end of many builds on your site and I must say you hit it out of the park with this one. Building it quit fast, catching a certain tranny pull & repair or more with chasing and repairing that clicking noise shows your skills are on the money. This Chev is going to be a ripper but it also would crush most road racers. I have learned much from you which I will use with the 2009 6.2 L9H in my garage but this build is making me very drawn in. Keep the info coming and good luck with all.
I grew up loving V8’s, but have grown a massive appreciation for the I-6, particularly the Atlas. Good to see someone building something this cool but staying humble about it. Keep up the great work!
sounds like its going to make more steam, yes the barras do have this problem, locktie red and good bolts, the manuals we found a small tack weld on each bolt, normally really happens when limiter bashing, thumbs up from down under..
@@spacedoutcowboy5211no. These aren’t f bodies. After 02 there’s hasn’t been one. Not sure gm even goes by body anymore. They go by platform like the newer Camaro and Cadillac are on the alpha platform.
O, WOW,,, mate, sesational, i had a flexplate develope a crack under load and it sounded the same, so i went with the plate, but not lose bolts. Mate i am over the moon for you guys, and hoping i can get close to your efforts, ALTHOUGH i am going NO computer... looking forward to the next installment...Eddie Australia.
That's remarkable. And touching that 8,000 rpm ceiling as well. It illustrates how efficient the cylinder head is with excellent combustion chambers. If this engine were to power a 24-hour endurance race car, what would be the ideal power level?
823 wheel horsepower is, more likely than not, over 1000 crank. That is absolutely insane power with any engine, especially one yanked out of what probably was a junkyard chevrolet trailblazer from 2009ish... whos stock crank hp is less than 300, and probably over estimated at that number anyway.
From the videos Richard holdener did a couple years ago, the numbers that it's rated at pretty much line up with what he saw on the Dyno. Honestly, given the boost levels currently, I can see 1000whp in the near future
I had a Trailblazer, I can verify off the line it was slower than my 2004 Corolla. After some research I decided the computer pulled power massively to save the stock transmission and driveshafts from idiots doing burnouts and trying to tow things without any mechanical sympathy. Sad. The best fix was an aluminum trans piston from a Camaro and the cheapest way to tune it was sending the PCM from the west coast to Carolina or something. Which I never did because we needed to drive the thing. So what I'm saying is the engine has the power, but no it definitely doesn't put it down very well stock.
@@milescarter7803 it was not slower then your 04 Corolla lmao. They are much quicker then many vehicles on the road and puts the power down just fine. Something clearly wasn’t right with your trailblazer cause I have almost 174k on mine now and embarrass lots of people and it’s not modified at all besides no catalytic converter.
Today at us131 drag way Martin..mi guy had a 4200 trail blazer engine in a dragster with a front mount distributor and 3 throttle body's went 4.96 in the 1/8 mile sounds wicked oh I forgot it's NA
What an amazing project that you are doing, congratulations! The only thing that bothers me is the 2 ecu to solve your needs, if you have the opportunity, try Fueltech ECU. If something doesn't work, talk with the support, they will do everything to make your project work. I really like that approach from them.
Now, this... this is the BIG F'N TURBO content im here for! Wicked sound and great numbers, can't wait to see what comes next. Also, the engine bay still stuns me each time you pan across it. Super clean and purposeful at the same time... its art.
Great job Calvin! Can't wait for more boost, and see it what this bad boy will produce when pushed. (Or do you plan on pushing this engine beyond 28 lb having the earlier crankshaft)?
I like how Calvin's thumbnail says 800hp, and it made 823 WHEEL hp. Ain't no clickbaity, roundy-upy, crank hp-y round here! Congrats dude.
It's gotta be getting close to 1000hp on those Crank bolts,...
Same, I like the conservative approach, always seems more impressive.
@@PiDsPagePrototypes and most would probably have had a sensational XXXXhp!!! thumbnail for clickbaitiness. He keeps it real
Undersell, over deliver. 😎 These guys are the real deal.
Amen!
IM HERE!
Glad you are! You guys are the best!
So am I
SS = Super Six
😂 💯
SupraSupra
That’s badass
We NEEEEED a sick Super-Six livery on it now 😂
Slipping slushbox..😂 🇦🇺 😅🇺🇸p.s. I love autos lol
I love the data overlays on the dyno.
Yes! It was awesome to see this synced up with the video. Keep doing this!
Yes, Wish more people putting out dyno runs would follow Calvin's lead on that. Real time data 👍makes it more engaging.
Amen! Dyno videos are boring unless there’s info or carnage
'nother Plus vote on the graphics here - they were clear and easy to look through and quickly follow what was being displayed.
Nice👍🏾
Wow 7800 rpms! Badass 🤘🏼
My thoughts exactly. Calvin, the 4200 Jeff sent you is putting it down! Love it.
Almost revs as high as the coyote does with two less cylinders
Most other popular straight 6 motors need like double the boost for similar power. That big displacement really is cool
As soon as I heard that rattle my first thought was FLEX PLATE!!! AAAHHHH!!! 😂 You see this on Duramax engines as well. Albeit very rarely, but once you DO hear it, think the worst, and then realize you didn't blow a crank, you don't forget it 😂

Yeah. It was a disappointment, but getting angry or crying won't fix it. I was elated when I found out it was the flex plate.
So glad the engine wasn’t broken! Also I’m sure everyone is here for drag racing, but man you could make a serious road racer out of that. The IRS is choice.
pretty sure this camaro has a live axle
@@e.v.a.l.s check about 0:53 into the video.

Loc-tite the threads on the crank bolts. lube the flange surface of the new bolts. Good jobs fellas! Cant wait to see it on the strip.

Awesome hp numbers. I never realized that these engines could handle that much. I've seen the 3800s get some good numbers. Looking forward to seeing it on the track.
You guys have built a monster! That high-rev 6 sounds awesome! I can’t wait to see you guys make a couple of pulls on the track!
Proud of you brother! I'm hoping that this engine becomes the next big thing. Your telemetry screen during the dyno run is very cool!
So cool. The straight six leaves plenty of room for that turbo, waste gate and the exhaust without getting the tubes too kinky. This looks to be working out well.

certainly weight/power is essential to these performance, ET, TS measured results along with traction.
You have really given my 252k mile Trailblazer a new hope. Ha. That’s coming from a heads/cam 2019 Camaro owner too. Keep it up brother.
Serious power from that 4200! Super clean build too. Looks great can’t wait to see it on the street and on the drag strip.
I just kept saying “flexplate” over and overall from the first sound. But you didn’t hear me 😂
Same for me too lmao. That sound is a pretty unique one. Once you've heard it you catch it everytime.
I've had a few flex plate/flywheels give me fits before. Heart sinks into your stomach and then your like " oh it's the flex plate " 🤣😂
When it's on a Duramax, pulling an Allison doesn't seem like any less fun though 😂@@robsorgdrager8477

I am excited with the results from the dyno!
I love it. GM should be taking notes on this thing. 650hp under 20lbs boost. Anyone could daily this thing.❤❤❤
You should get some crank bolts that are setup for safety wire, then you can tie them down and they will never come apart!

It’s like they don’t want the straight to be used for a more capable tractable platform
It’s clearly a capable competitor to any other inline platforms made by other companies the world over
To be fair, it's very hard to fuck up a straight 6. They just mechanically are very sound to pull power out of.
Wow guys. I can't wait to see what's next as well as some times. You guys are genius.
Over 800!!!! Hell YEA!!!! GOOD JOB BROTHER!!!!!!

Great problem solving again!! Looks like it will be a Beast at the track. Hope to see that ASAP!!

This build is insane!!! I love it. It is one of my favorite cars you have built.
Whoa!!!! This is absolutely incredible! You guys did a great job and I can't wait to see the car run at Sick Summer.
I really like that car a lot, even though older weirder stuff is your thing. Power numbers are impressive. Cant wait to see it run!
Ive been watching for about a year now and i cant wait to watch this car eat. You and your dad are doing amazing work keep it up calvin!
Great job! Cant wait to see this thing rip! Also wanted to say that I appreciate the data displayed during the dyno pulls.
Glad to see Andrew back in the swing of things😊
Kudos for the "live" telemetry.
Dang man, that did incredible, I love this project
Nice work on the flex plate diagnosis and fix taking a bad day to a great day! 823hp! Hell yeah brother!
Very cool stuff cal can't wait to see her hit 4 digits. Just a little No2 and she's there

This progress is so exciting. Hopefully this becomes more mainstream and there will be mass production of kits for conversions
Im super stoked for you guys this is just as cool as the studi even tho i know its not the same 😢 good luck 🤞 Car Parts can pop up years later 😉
Awesome video! I like the PIDs at the bottom of the screen 👍 Very nice build, guys!
Thanks.
Maaaate, WELL DONE. Maybe look at a locking ring with the fold up tabs to keep the bolts where they belong.
Great results, the new data overlays are sick.
Nice build up Calvin, I have new respect for the 2010ish style Camaros . Never thought one could be this cool. Man, I just love it!!
That last pull with more timing really helped with the lag around 5,xxx
Well, that canary yellow Camaro is singing quite the song !!! Revving to the moon !!!!!
I like most of the videos you make. This one was well done. The car is amazing.
That looks really nice! Good job! Im really looking forward for more. Cant wait to see what it will do!

Very Kool. Glad to see Y'all get a win!
See if you could get arp bolts that could be wired like aviation safety? Who knows
again the nonsense !! 😲 with another ignoramus
Very impressive H.P. figures, well done ✅👍.
I would cross-drill the flexplate bolt heads and safety wire them. It's cheap insurance.
We are so proud of y’all, we’re all hoping we can do barra builds half as good as y’all one day, lol

Yes, very excited. Looking forward to track time.
Great. Keep up the good work. Forward to 1000 horsepower.
Love the sound of the engine
Great progress!
Awesome build!
Great job guys! No reason to push it any harder just to get a dyno number. You can always run more boost at the track to get your 8.50
