Awesome Job Lazer and friends helping the guy out, hio, darth and any others!! Any adjustments going to be made that will impact track performance before you go to the track? I see you will be updating injectors, do you expect to see a gain from that? and when is the track date?? I am ready to see that thing rip!!
I love SBE NA setups after the car was pushed as a bolt on car. I just picked up a c5z and have been looking to implement a lot of what I've seen on some members bolt on setups for myself.

7.4 or .77 lambda of 10.0 stoic. What’s your set up? You’ll just have to play with timing. 33 is about all I can get in it on E85. I didn’t do any tuning on the dyno. I street tuned it and just made some pulls for the intake test. My fuel injectors were tapped out so there was no since spending a lot of time beating on it.

No were near as good as you. I have a nitrous motor tho.
500 on motor it was like 496hp.
737 hp on 850 ( roughly) psi this was on an .062 jet ( supposed to be 150 shot)
And spun on the Dyno on my way over 800hp at 950 psi.
The interesting thing was at 11.6 afr and 30* it's was 450 . We then ran it at 12.5 afr 30* was 480. Pulled it down to 28* and went 496 hp.
But it peaks early. Like 6600 rpms that's with a 240/250 duration cam.
was over 90% duty cycle on the juice 80lb injectors. Never got to the 2nd kit. Dyno wouldn't hold past 750 hp. It would spin

Not enough exhaust duration, especially for a nitrous application. How'd you spec the cam?
28* has been the magic number for my ls3 applications so far. Always seems to be what they like. Don't seem to be spark limited, just stop making power past 28*.

OP, just out of curiosity did the dyno operator mention what was going on around 6700? When I used to dyno bikes that's usually what it looked like when the clutch was slipping then finally hooked up after peak torque. Or a little tire spin.

I am the dyno operator/tuner. I had a 3 degree timing bump there. 30-33 I didn't spend anytime one the tune on the dyno. I street tuned it and just put it on the dyno for test results on the intakes.

Big shout out to Pantera EFI for the injectors! Great deal and thanks to Darth_V8r for helping interpolate the data. This thing really moves out! I was able to do a nice 3-4 pull yesterday up to 136 MPH and WOW what a feeling lol tune is dialed in as best I can get it on the street. I will do a little more at the track Monday after I get a few clean hits hopefully. Wish me luck!
Good luck man! I live in Arkansas, and GPI is about an hour away from me. It's cool to see their stuff making it across the nation. Good luck Monday man make some killer passes!
