I made two passes tonight. The first pass was a 13.6 at 97 missing 4th gear. The second was a 13.3 at 109 with a 2.3 60'. The car bogs bad out the hole but I am on the 3-bolt rear and stock center diff so I am afraid to launch it. Holding the rpm's at 5k and slipping the clutch resulted in this 2.3 60'. When I got back from the track I hooked up the clutch wire and want to go back to the track tomorrow with the stutterbox and no lift to shift to see if that helps with the lag. Leaving the track I beat an LS1 from a 3rd gear roll, the LS1 had just ran a couple 112mph passes. Im currently on 22psi and pump gas with a 20min tune on the car. I have the eprom for 850's, MAF translator set to stock and AFC set to -10 across the board on the high setting. The car gets 2-3 counts of knock in the upper rpm's and gets 18 degrees advance. The car weighs 2,950 and I am about 150lbs. Keep in mind I'm still on a stock downpipe and stock cams. RNR 3'' exhaust is in the mail and I am looking for a set of 272's.

respond to mine.
.. a bit on the harsh side.. but true.. any turbo will suck without the proper support... stock cams and stock rev limiter are robbing you pretty good right now probably.. and you definitely need some tuning.. that size turbo should be trapping 115+ on pump at 22 lbs. i can honestly vouch for the claim that big turbos are not for beginners... my going from stockish sized turbos to a garret made me have to completely re-learn how to tune and how to drive. too many people these days aren't able to deal with that and end up with 13 second cars with 11 second turbo setups..
