Nicely done!

Looks killer Jason! Can you explain why there is much a dip in the torque curve between 3 and 4k rpm?

marcouvo

Quite a lot of numerical difference between peak HP and peak TQ.

Katech_Zach

That's called Jason's built in traction control.

Some of that could be tuned out/smoothed out in the future but for now we are leaving it as is.

Katech_Zach

That's because we are making a lot of extra power up top with the cam phaser.

marcouvo

Very cool. I'm guessing a smaller camshaft would increase low rpm TQ, 2000 to 4000 rpm.

Jason, how does this compare to similar ls7 engines you have built? By similar I mean camshaft and compression. Wondering what you think the di and vvt are worth if anything.

Katech_Zach

A similar LS7 camshaft/compression (12.0:1) makes 660hp. We are getting a lot up top with cam phasing.

wjnjr

Nice!

What are the plans for this motor?

Katech_Zach

It is going in our 2014 Stingray and will be sold with the car afterwards.

The engine will be one of our standard Gen 5 engine/vehicle packages.

Thanks Jason. That is a considerable difference. Would make an awesome track day setup.
