8-1 header on Destroked 6.0 engine dyno at 30psi
HTML-код
- Опубликовано: 12 сен 2024
- Destroked 6.0 with a Callies 4.8L/3.268" stroke crank, C5R heads, custom 8-1 header by One Guys Garage, and a Forced Inductions S491. This was back in March of 2020, I have since sold the turbo setup and the engine is in the car NA right now. The 8-1 was fun but it really hurt the top end power and RPM of this particular engine, if I were to do this again I would like to do larger primaries and collector size. It did spool very quick (contrary to popular belief), and made good low end power for its size though! 30 psi and 1500HP
I've always wanted to see this with a flat plane crank and 8-1 pulse paired twin scroll setup. It would make equal length tricky but look/perform insane
Flat plane crank + 8-1 header..... wouldn't that be kind of redundant in terms of exhaust scavenging? Maybe not
@@ellisjackson3355 Yes. With a flat plane crank, a 4-1 dual header + exhaust would provide less flow restriction than an 8-1 header
Flatplane crank isn't for exhaust scavenging, it's for balance, they don't need the same counterweights as a cross plane crank so they tend to weigh about half as much, which means much faster revs.
The flow and scavenging of an 8-1 header vs a 4-2 setup would depend on how well each is set up. An 8-1 is a lot harder to fit into a body though and would have a much longer minimum primary length, so that would limit the range it could be tuned for
@@silentbobfan32 Flat plane crank is best for exhaust scavening and not needing to have those crazy exhaust headers to make use of the benefits of the scavening effect.
Cross plane cranks only exist because they run smooter.
So that is why you see flat plane cranks only for racing or sports cars.
Example: Ferrari 308 has flat plane crank, Lancia Thema 8.32 has cross plane crank. For the rest it is exactly the same engine in a Sportscar vs a 4 door Saloon.
Has anyone ever tried designing a cam for a flat plane crank? If so, what were the results? And how did the cams differ?
It’s enough to make a grown man cry.. *sheds freedom tear*
Happy to see this going. I bought a 4.8 crank from you on ls1tech years ago. Still haven't used it. I always liked your build.
Very cool. I forgot to mention this wasn't a stock crank, but a callies unit I bought from a guy at Katech, along with the C5R heads on this engine. A stock 4.8 crank might be just fine at this level though too!
@Jakson S any chance that you have that Callies part number for that 3.268 crankshaft?
@@edmundnlemadim8480 im interested 2 i got a ls3 block and heads to build this setup
Why would you destroke an engine in order to make far less torque and hp
@@englandtra i think characteristic curve but Who knows..?
I love this out of the box thinking I’m in Australia and currently CAD designing reverse cylinder heads for my LS with exhaust in the valley so I can do a 8 into 1 short manifold into a single 98mm turbo.
It will have twin plenum chamber intakes manifolds on either side with twin 90mm throttle bodies water to air intercooler using the AC system to chill the water all this on a destroked 6L on E85 wish me luck it will be unique if nothing else.
Please keep up with your content it is fantastic I can’t wait to see more.
Big fan from across the world.
i want a follow up on that
i need to see that
Update
I hope to see some video of that
Not sure your stock AC compressor will have enough capacity to really have to much effect, unless it's just for cooling between pulls. Not sure where you'll get a small heat exchanger either but I wish you luck regardless.
How that holds together is unreal
Because LS
@@bigboreracing356 more than 1k hp on stock bottom end ?
It holds just fine because the rod length is shorter than the one used in in the 6 liter which is 3.622 inches and the shorter rod does not make the crankshaft wobble like a noodle at high rpm. An upgraded top end pushrods, rockers and lifters and you're good to go.
Because it's not making any boost, look at the intake tube
@@Truthcanbeconfusingthis is actually incorrect, the 4.8 rod is longer than a 6.0 rod
4.8 -6.298”
6.0 -6.098”
Good Lord, that thing sounds angry!! Whackin’ the throttle in garage produced a sound I’ve never heard b4 👍
That's actually kind of refreshing, what a beautiful motor.
I did a lot of research and reading when I was looking for headers from my Caprice PPV. I came across a post saying that the 1-7/8" primaries killed low end torque and horsepower. In fact, the poster had 1-3/4" headers on his G8 and a header company offered him to demo a set of 1-7/8" headers. He put them on and hated them because of the hp/tq low end kill and put the 1-3/4" back on. He called the company and started asking some questions. The header company said they don't recommend running 1-7/8" headers on anything below 440 CID. He asked then why do you make these and the company rep said "because people believe bigger is always better and they will buy them".
Those Bluetooth intake pipes look killer
Build something better fucka
You dont read The description sure
All you have to do is wait 15 seconds
@@Christdeliverme with The Hood closed should do a 0,5psi without intake pipes lol
😑
Whenever I get around to doing an ls, I want this exact setup lol... raddest sounding, most insane looking setup ever😂
Dear God man. I was talking out loud, 900 then that thing kept climbing. Holy S. Back that off some and have a great life holy F That's a small block. I can believe what I just saw
That was a fun day Jakson! hard to believe that was already 500 Engines ago for me haha Currently at #10,715
Sounds incredible 🤩
What an absolute unit
Those numbers are amazing, and the only thing I’m stressing over is where should you put this thing, that header is gorgeous! (I vote the trunk lol)
The 8 into 1 looks awesome. Very well done
0:42 "best motor for a compressor ever, will get bigger storage tank soon" 🤣
Sounds wicked! Thanks for posting!
I absolutely love that engine. I've built a few destroked engines. I built an NA Subaru engine 10,000 rpm redline engine. Wish I never sold that car.
But this engine and header combo is heaven.
I put 1400cc heads with 1600cc intake valves on a 1600cc block. Compression was 14.25:1. my big mistake was cutting a bunch of weight off the flywheel.
I love the block being used as a stand
Nice! It also confirms the ~17.5 PSI to double the HP of an engine equation used by Procharger.
and only 1 bar (14.5psi) with a turbo =)
It sounds so dam good it rips the RR's off from a idle Holly shit I love it !!! Thank you for sharing it made my night bud!!!
Nice build, something to have that you'll never run out of usable power, can crank it up or down like the volume as desired.
What an increase between the three runs.. Just Badass....
Two thumbs up 👍👍 for this epic set up
Wowww, music to my ears! While running in the beginning it sounded very much like those Nascar engines I was waiting to see how high she revved to see if it infact reassembled one lol
i loved how it just casually jumped like 500hp as soon as the turbo spooled on those 2 runs
I need to comment again, I've watched this video twice now.
Natty it's almost 600, 30boost at 1500?!?!
God DAMN
Probably lots of exhaust scavenging going on, I love it.
That was the coolest video I have ever seen…. Job well done 👍
Christ! I always loved the way equal length headers sound, but figured it was only an NA thing. Myth, busted 🤘🏾
In this case it's the 8-1 connection that makes it unique sounding.
Well as far as getting it to fit into a car it is a myth😊
Shes all power love the sound your a genius at hand 🙌
Them heads were getting HOT
O... M... G!!!! That was AWESOME! ❤ Good to see the tuning bringing it all together.
DAM! didn’t know equals improve the sound that much!!
Holy dog shit. Wow that’s just amazing. How in the hell did that not blow up?😂
Got to watch it again all teeth out grinning!!
Don't you just love it when people say sh#t like 'a turbo just always ruins sound'...no sugarpie, it's your faulty header design what's causing it to sound like a freakin lawnmower(this is an awesome build)
This stroked my insanity!
Great video of a great engine doing what great engines do....Roar!
I'm impressed! Well done!
That escalated quickly!
Man, geez.
Nice Sound V8 with 8@1 headers!
1500BHP 5.3L turbo V-8, you can put that into a lot of things.
One wild sounding LS! LOVE IT! SWEEEEEET!
Well, that's just crazy. Love it.
Take that Hellcrate!!.. (now that's impressive 👏)
😂
Yeah but you can’t fit this into a car
Straight fire. Protect that engine at all costs
I love those 8 into 1 headers.
That’s crazy power!
That sound 🤯
Wow!!!! Tones of power👍👍👍
Sounds insane
I love the stuff supporting the turbo and exhaust. Definitely some crap I would do😂😂
Yes sir, it was sketchy. Moving it around on that engine stand I put a 2x4 under the crank pulley, Lol. In the car it was supported.
Awesome work man. Killer numbers
Wow, that is very impressive.
What a power house
THIS THING IS WILD!!
Sounds awesome at the 30psi great job thanks for sharing
Daaaaaammmnn very nice work
Gorgeous wicked sounding motor! But what’s it going to fit in?
The song of my people.....
That's badass sounds killer
Excellent work sounds fantastic
wait.... that tiny air to water intercooler is flowing 1500HP! wow!
Yes sir, it is a frozen boost type 15 I believe. Measured pressure drop during this session and it was around 1psi. I'd have to look back to see what IATs were exactly, but they were definitely within reason, just had city hose water running through it.
THAT'S WTF I'M TALKING ABOUT!!!! Just the thumbnail alone....very bitchin!
Absolutely fabulous well done it’s got me thinking 🤔
Got a friend that has a destroked Ls with a 98mm turbo it’s got all forged internals and aluminum rods it runs real good
Hey my brother imma need you in this near future thanks you for the video I am in Louisiana I will see you later big brother thanks
You sir are a god
Top notch Sir,,, 💪🏼💪🏼🤙🏼🤙🏼🤙🏼
SS/S = super sick and slick
bruh!!! sounds sooooo good!
You’re my hero! That’s awesome!
That turbo almost winds up to tinnitus frequency 😁
Might wanna open that garage door
Can you elaborate a little bit on the destroked part. What is it, what it used, why it’s done. Super freaking cool, love the project!
I'd imagine they reduce the stroke length for higher boost tolerance or higher rpm or both. Less distance that the piston has to travel. Shorter arms=less reciprocating mass. This is all an assumption, not my engine.
@@NG-VQ37VHR I’ve done a little research and found Richard Holdner has a pretty good video explaining it all. Definitely makes sense in certain applications
Shorter stroke allows higher revving and less side movement from the piston and rod.
Looks cool and sounds cool, but other than a dragster, what the hell would this fit into? A 1st gen Monte Carlo couldn't even swallow up this package, and they have like 3 feet between the engine and the radiator.
Judging by how glowing hot that merge got, you need to go bigger on the merge and probably bigger on the turbo to reduce the restriction.
Larger turbo would still spool pretty well with a fairly close back housing to this.
But yes, you built a nice sounding and good powered setup. Larger turbo would do the same but with less boost.
That is awesome Mr.
That was incredible
Poor man's 180° exhaust pipes
Smooth sound l can listen all day 😮
Friggin wild !
thats frickin awesome bud
OMG, HELLS YEAH!!!🤤
Love it! I want that engine at 14,5psi, a very happy mean sounding thousand hp engine
14.7 psi? My goal is for 15 psi in my 408 E85 with a 88/103mm turbo
The 2nd pull i was like awwww cmon cmon hit that 1k!!! Hit it hit it! Aww alright next one. Woo 1k! Yeahhh- oh okay damn. Oh. OH OKAY! Awesome build lol.
I want to see a 4.125"-4.155" bore block with a 4.8 crank under hard boost for fun. I doubt there are any proven advantages of de-stroking an already small engine like a 6.0. Same heads, cam, intake, turbo, fuel system, tuning, compression, ect and the 6L will make more power from every unit of size until the engines both simply reach the limit of the turbo, fuel, head sealing, system , ect.
Sounds good! much better than regular american v8. Sounds like a italian engine or something like that.
That Will Work ✅ I’ll Take It
Sweet build... what cam did you use? Specs?
Thanks. It's a Comp solid roller from John Bewley. 240/248 on a 112
That's great fellas
God it sounds so good. Just sucks it's so hard to package 8-1 headers into a vehicle. Let alone with a turbo strapped to them. Is this motor going into anything?
That thing smokes like hell what is it some kind of two-stroke???????
Damn that’s a unit! I need that in my old sleekcraft!
totally nuts!
Well it's an expensive way to deliver exhaust gasses to a turbo, but does it make more hp than a set of stock manifolds feeding a turbo? And no don't say that it made more hp NA so that's proof. The turbo is a blockage that would kill the scavenging effect (which is overcome by the boost it creates). I would suspect that how you deliver the exhaust to the turbo makes very little difference.
Thing basically makes 1500hp, holy shit xD
Great job. Do you think that it would be possible or even feasible. For ne to use an 8 into 1 header on an LS and then split/divide the single pipe into 2 for a twin turbo setup? I realize that the plumbing would probably be a nightmare. But I like the exotic sound of the 8 into 1 and with twin turbos it could act almost like true duals if it is turbo back exhaust from each turbo. I would also like to swap the LS into a Ford Crown Victoria because of the larger engine compartment. What do you think?
@@SVThailand @NA Blank Let me know if that ever becomes a reality. I'm sure that the boat would sound great and with two engines it would also be extremely fast.
What cam specs? Sounds brill! btw!!! I have a very similar combo with a 263/273 113LSA. Does 585 NA and 1065 on 13psi. Haven't turned it up yet. No 8-1 but man, the sound alone is worth the less power IMHO. Mine sounds nowhere that good.
Thanks, it was a fun project. I did like how it sounded, and sometimes wonder if I should have kept the 8-1. The guy that bought it actually is trying to sell it, I've considered buying it back a few times! The cam in this one is a 240/248, 112lsa. Its in the car NA now with 1-7/8 headers. Pulls good upto over 8000, pulled to 9000, but it definitely wasn't making power up there, ha. I plan on throwing it on the chassis dyno this spring. I have a set of turbo headers I want to make another turbo setup with, but I'm not in a hurry to do that. I just want to enjoy the car as is for now, without sitting apart in the garage!
@@turbotron2 Very nice!!! I hear you on the enjoyment part.
I built a similar one for a buddy that is also now entirely NA and we're thinking of changing (same cam as mine) to something like a 260/266 at 104LSA. It's a circuit car with a sequential box and could really use that acceleration down low. Thankfully I won't have to tune it, as tight LSA's have never been my thing. But I'm really curious to see first-hand just how much of a difference basically only changing the LSA will make to how it performs on track. Duration is near enough to making no difference. Sound, too. Wonder how different it will be considering it's already a pretty big cam.
@@dons1932 Did this ever happen? If so, is there any video of it running with the new cam, or any data?
@@tptrsn It did but not on the same engine, I built another one with that cam'. For the same car. With an 8 runner trumpet / cross ram intake.
Made a little more everything, everywhere - as tighter LSA cams tend to when aspirated. Bit more power, bit more torque, everywhere. Not just low or peak RPM. It turns 7600rpm. About 16hp more.
It was definitely harder to tune down low from what the tuner told me, and is not as streetable as the wider LSA. It idles really well but it gets fuelled up with light load and low speeds. It is built for the track. Funnily enough the valve overlap in degrees is actually near as makes little difference between them. So they are both about as angry as one another, I'd actually say the tighter LSA cam starts and idles better! Both have MoTeC ECU with Lambda. With an X Pipe, 4into1 merge and tuned stainless exhaust it sounds like a V8 Supercar. Has that screaming sound similar to this video but not as pronounced as 8into1.
@@dons1932 That sounds like an amazing beast of an engine, must be a lot of fun! Thanks for answering!!
I thing sounded sick..
