got some track numbers, still just the 1/8th. before was .68 ar and stock cam. after is .96 ar and 2001 z06 cam.
before at 8psi we ran 7.46@94.8, this week at the same 8psi with the same 60' we ran 7.12@99.5
before at 18psi we ran a 6.63@106, this week at 15psi(turbo maxed out) and the same 60' we ran a 6.51@110.5
our best 60' so far was a 1.55 with most of them in the 1.6's. we are going to get a 15" rim on there and then some fresh tires that are a bit wider and maybe taller. we are also going to try some adjustments with the suspension. we will keep working with traction till we are at least cuting some consistant 1.4's.
110.5 is prety fast in the 1/8th. i think it will run out the rest of the 1/4 just fine.
i dont think there is much more we can do to make more power. the turbo is maxed. the injectors are at over 95% and my log shows around 12/1 a/f ratio on our last run so they are prety much done. the motor can't be too far from being maxed out and we haven't even checked the fuel presure but we have to be near the limit for the fuel pump. i am prety excited to spend some time on the suspension and tires just to see what we can do with it. we have a few ideas.
after many dyno runs, street tuning and track runs we have our first problem. there is an ocasional heavy smoke. not there all the time. must be the turbo seals or something to do with the turbo oiling system. we didn't put any restrictor in the oil line. going to try and get that done and hope that takes care of the problem.

after looking at the log we once we go wot we never go under 5600rpm. that can't be ideal. probably should pull out that converter and get it tightend up some. i dont think there is any point in trying to figure out the ideal shift points when we are blowing thru the converter as bad as we are.

after reading your results w/ the 5.3, I started keeping my eye out for a z06 cam...
I found one w/ the yellow springs and pushrods out of an '02 z06...
haven't installed them yet, but looking forward to it...kp on ls1tech ran one w/ a ProCharger for a long time...and it looks as if you are having success w/ it in the turbo'd 5.3 as well...

I told you your **** runs quicker than mine because you have an itty bitty cam.
lol!!! You just wait buddy.
