He got tired of the 4.8 and went with the 5.3 is having issues never got a chance to run on 20psi but did get a E/T:*10.79@127.8*(16*psi) and a best of 131.4 trap speed on 18 psi but was having issues on that run...so you running like home made caltracs?should work good im guessing 373 on the rear ..he was around the same and still running stock tb and intake and heads

Yeah I have a small fabrication shop and build lowering kits, c notchs, traction bars, narrow rear ends and a bunch of other stuff. All my kits are CNC cut and mig welded. They work well. And yes the rear gears are 373. Heres my flip kits and traction bars.

This setup drive's pretty much like a 60mm on a 4.8, but has top end of the big turbo. I don't know why you all think it's gonna have boost response like a roots blower! 
It's still a turbo setup with a couple of turbine to spin up off idle and it does a pretty good job of it I think. No way you could get this kind of power out of a 60mm turbo alone!
They are BW S480 T6. 96mm/1.32 a/r hot side and Magnum T60 P trim with a T4 .96 a/r hot side.

Didnt get to run mine at 20 psi cuz soon as i got off dyno, fuel pressure was dropping, guess the load on dyno wasant that close to being my trucks weight. So lowered it to 18 psi, and ran once with a crappy 1.9 spun all through first gear 10.90@131.4, until next run when my wastegate vaccum line melted with the tranny oil line and made a piston go bye bye...
I also run on flip kit and caltracs, although i kinda like more how urs looks lol..mine are homemade also.

Damn I hate issues!!! So far this time has been the best so far. Best part is I finaly got it tuned right. A 10.9 is still very impressive for a little 4.8. Foose has the time to beat though and im going after it. Haha for now I will try to get my 60ft better. I have a long way to go if I want to get close to foose's time. Think he ran a best of 10.1.
