After several years my setup finally made it to the dyno. It made 602rwhp and torque was right around 575 at 7lbs of boost on a dynojet. Setup is 408 with OFI turbo kit and S91 turbo through 4l80e and 9". I know the drive train isn't the best for dyno numbers. Just wanted to see what everyone here thought.

Brad - Just for comparison, my twin 57mm setup, forged 8:5:1cr 347 made 603/600 thru the 4L80e, 14psi, straight 93 octane. stock 317s & LS6 cam.

I think you numbers look good for 7psi

I think those numbers are on par and actually pretty decent for 7psi. That turbo isn't even close to its efficency map at 7psi lol. Your barely leaning on that combo...good numbers through that drivetrain!

That sounds totally normal. Was it locked?
