How High can you spin an SBE Gen V LT Engine?

Get ready for a packed journey into the heart of engine performance! 🚗💨 Join us as Team GPI takes Spintronics to the next level at EFI University, where we unleash the raw power of an SBE Gen V LT engine, pushing it beyond the 9000 RPM threshold.
🔧 In this exclusive video, witness the precision and expertise of our team, Ben Strader's team, and CID as we integrate Spintron technology into the heart of the high-performance Gen V LT engine. EFI University provides the ultimate stage for us to fine-tune, optimize, and push the boundaries of what's possible in engine performance.
🌪️ Brace yourself for the mesmerizing spectacle as we spin the Gen V LT engine to unprecedented speeds, capturing every moment in glorious detail. It's not just an experiment; it's a symphony of power, technology, and innovation coming together.

High rpm n/a stuff is my jam! This would be a killer set up in a 10 speed 1le or rs Camaro with the V8 option

[@DavidB7474]

Yeah Smokey Yunick used the spintron decades ago. He new that things like valve springs work differently at rpm’s. It’s why we use different spring diameters, different spring material. Maybe One diameter coil has issues at a certain rpm, then Al the other diameter spring has a harmonic frequency at another rpm, then they can help cancel each other out. Science is really cool.!!!

[@JohnSmith-fi2ck]

Wasnt his called a Smoketron?

Great to be able to analyze the working results of a variety of combo’s via digital and laser sensors… Real game changer!

[@pinkysgarage4517]

So cool. At first, I was thinking - no headers, balancer, intake, etc - what the heck? Then I watched the video. I'm an old gearhead, and not a tech geek. But this stuff is amazing. GREAT video!!! And new subscriber!

[@lancelanphier9509]

Wow, that's incredible! Sure is great information to know! Thank you!!

[@330MotorSports]

Thank you all for the testing/development and sharing it with us. I’m building an ls/lt hybrid and I’m thinking about a custom ground camshaft… 6.0 GEN4 with 2021 Silverado 6.2 LT heads. 😅 currently only BTR has a camshaft.

[@realshidd3062]

Same thing I’m about to do with my L92 6.2. Im adding LT1 heads with custom cam

[@lanegeisewite1436]

Sweet sweet sweet Chevy powaaa!!🇺🇲🇺🇲🇺🇲💪💪💪💪

[@larrynorsworthy8582]

And done with pushrods!❤

[@antoniobarrientos1230]

Me encantó su video y toda su información 🔥👍

[@Tracked_1ss]

Amazing work, guys! 👏👏👏

[@spanky7774]

Put this setup in a car. Would be very interesting.

[@Stevens7983]

Its going in a 2700 lbs 6th gen with a TH350 3 speed trans.

That baby was humming

[@johnnystock1849]

Wow congrats !! Makes my solid roller 8000 rpm LS looks dum

[@bowsertownes]

Very cool

[@Venom99street]

Holy wow 🔥🫡

[@WildEngineering]

is the stock bottom end, e.g. pistons and rods capable of 9000RPM?

[@C6Z_Bob]

I doubt it. They're pretty stout, but 9000 is a LOT of RPM. I would definitely want a forged piston and probably a forged rod at that RPM

[@jamesgeorge4874]

Nobody is bolting those heads and using that valve train on a stock bottom end....

[@Stevens7983]

This is going on a SBE. 9000 is asking a lot long term. We have 30 engine dyno pulls so far on it up to 8600 RPM. This combo isn’t limited to sbe stuff, or na stuff. It is available for all LT applications.

[@WildEngineering]

@@Stevens7983 Im really just interested in high revving N/A stuff. I guess it would be recommended to have forged pistons/rods at 8500+rpm?

[@J2A61]

Just want to say my 5.3 L83 dogs stock and modified NA LS out 😂 I’m glad I did it the hard way now…. Different plus has some balls LT genV is the way to go 5.3 and 6.2. To be honest the only lightly modified car to beat me has been a 6.2 LT. Look through my channel and you can see the race for yourself. Glad I seen this video. Back to the drawing board 😂

[@HioSSilver1999]

There really isn't alot of difference in them. The compression ratio and vvt helps to flatten the tq. If your lt is just out right dogging a ls....then someone fucked their ls up

[@J2A61]

@@HioSSilver1999 I don’t know my friend but maybe I just have a freak of nature or something but I’ve race a cammed 5th gen camaro 6.0 at the track and kicked his ass my brother owns a stock 14 camaro SS 6.2 kick his like it’s nothing, I’ve raced a C6 on the highway and made him exit 🤣 392 scat too… and to make that even worse i have 22” wheels on my camaro…🤷🏾‍♂️ I just now like yesterday put it on E85 and I have to get some transmission work but going to bolt on a LT2 intake and a bigger throttle body so I should be neck and neck with the LT1 next year…

[@HioSSilver1999]

@@J2A61 hell we beat cammed 5gens with just a bolt on 5gen....cams don't mean shit most of the time. We went 11.5@120 with a bolt on 5gen. Then did a c6 and went 10.5@132. My own bolt on ls6 went 10.7@130ish. The people you're racing don't know wtf they're doing if your l83 camaro is within 3 busses.....or you have something going on you're not telling. Like a gutted car, power adder or massive gear in a short race. Apples to apples or it doesn't really mean much.....definitely not worth bragging about.

[@realshidd3062]

I need parts list for this setup

[@suicidal_racing]

interested in what rockers and the lifters did.

[@Stevens7983]

The Mantons limited us about 600 rpm lower. The lifters performed the same as the different pushrods did. (Ryan at GPI)

[@DavidB7474]

Has anyone run just the short block? Without a valve train? Just wonder if there is a limit to rotational mass, or imbalance, wonder at what rpm limit the rotating assembly has issues? Just a thought.

[@Caddydaddy2003]

how are you taken a psi 1513 spring to over .700-.725 lift? what was installed height?

[@Stevens7983]

We have to use longer than stock valves, and on top of that they are 7mm stems to keep them ultra light.

[@Caddydaddy2003]

so what is installed height? they appear to have 160 at 1.800 are you going to like 1.850 and dropping seat pressure?@@Stevens7983

[@justinw6448]

Did I miss it but did they end up using the 903 lifters?

[@Stevens7983]

No, we used the .842. The .903 was not any better in this application

[@David-yy7lb]

Isn't there less stress on the crankshaft and rods spinning from an outside source vs the combustion process putting more stress on the rods and crankshaft at the same rpm?

[@C6Z_Bob]

I don't know the answer to your question, but they're only spinning the valve train here, not the rotating assembly

[@David-yy7lb]

@@C6Z_Bob Oh ok

[@181le6]

@@C6Z_Bob What? Dude the crank is spinning.

[@7000U9ZHIFT]

Is the gen 5 sbe more capable than the gen 4 sbe ?in terms of rpm?

[@Stevens7983]

About the same. We have turned both upper 8000s

[@J2A61]

You guy said a lot without saying nothing 😂🤣 Come on man, what parts did you use🤷🏾‍♂️

[@Stevens7983]

The parts in the package lol. Jesel rockers, Johnson lifters, our cam and heads.

[@DesTakeFlight]

So the Johnson 842 lifters held up better than the Johnson 903 lifters, I’m going off what u said u were using that held up to the max

[@Stevens7983]

There were no performance differences between the 2.

[@DesTakeFlight]

@@Stevens7983 alright! 👍🏾

[@bigg_50_jonn]

ok ... please excuse my ignorance ... but ok this engine will spin beyond 8K ... I want to know WHERE does the power band begin to fall off

[@C6Z_Bob]

That depends on a lot of different factors, the cam and intake manifold being the most important.

[@Stevens7983]

This particular setup on the engine dyno peaks at 8300 and hold on well to 8600 ish.

[@shephusted2714]

internal combustion is eol - the way it is

[@rodpalm6398]

Jesel rockers not Jezel.

Sorry, I will make our pronunciation department aware of this grave error!
