High RPM on an LS V8
 

In town there is an EFI school, and it run by a guy that was a pro stock driver, found this today on his work with comp cam and making an LS spin 11K and where there at now.

I guess I don't really see the need to have something like this around. You can make a great bracket racer that only spins to 7k if you want. This is my favorite part of the article:

:lol::lol:

Thanks for sharing.

If you road race more RPM with power the less shifting if the Z/28 went to 8500RPM no need for 5th gear on a 3 Mi track with turns,

I agree with you when it comes to road racing, but the article said the car is for bracket racing.

Thats there plan, but if this works and you can safely move the RPM up on a road car then we are that much better off, no?

Hey, I'm down for testing the limits like this for sure! Why not? And Jesel makes great rocker arm systems. I just thought it was an interesting application to be doing it on. Hell, might as well try to go with pneumatic valves at that point. :thumbsup:

Pretty awesome, would like to see/hear the final product on the dyno.

Jesus thats bananas! I'm always a fan of "let's do it for the sake of doing it" projects

But even while road racing...more torque down low makes up for the less shifting with a high rpm engine. Check out the Head-to-Head M6 v A10 ZL1 lap...the LT4 make so much torque, it could just run out the gears, even at lower rpms.

C7.R does damn well in competition with a 6000-some redline.

Typically, high torque engines are larger displacement, and have a lower relative redline. And a low-torque engine needs to spin higher to make up the performance, like the Voodoo engine in Mustang.

The LS7 was that "sweet spot", balancing high RPMs, with high torque. There hasn't been an engine since then that could do the same sort of thing.

You'll rarely find both in the same package...would be wicked if this "Spin Tron" was reliable. :thumbsup:

And more news today, there is a NASA (retired) engineer out there that with his sound equipment came up with this, the new ZR1 is shifting at 9000 RPM, so this may not be that far out if its true.

found the link hope it ok to post.

Should we cancel our ZL1 1LE orders and wait for the Z/28 with this engine? :eyebulge:

That's pretty interesting! Guess time will tell if true.

I did not say that, from what i know from talking to people in the trade there are better engine in the works, :)

I didn't mean to imply that you did. I was merely being facetious.
