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

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.!!!

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.

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!

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.

@WildEngineering 7 ай бұрын

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

@C6Z_Bob 7 ай бұрын

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 7 ай бұрын

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

@Stevens7983 7 ай бұрын

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.

@@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?

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

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

@Stevens7983 7 ай бұрын

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

@Caddydaddy2003 7 ай бұрын

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

@Stevens7983 7 ай бұрын

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

@Caddydaddy2003 7 ай бұрын

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

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 7 ай бұрын

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

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 7 ай бұрын

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
