That's leaving at about 6-7 lbs off the Lingenfelter 2-step. I think I could go 9-teens in it with this setup still at the 10lbs of boost. Three more boost levels are only a button push away

I do think we are going to need less gear for the higher boost though. Its JUST shy of the limiter right now with the 3.55s. Probably gonna go to a 3.08

I dont keep the slips, the owner of the car does. Im thinking my 60' on that one was a 1.40. Still a ways to go there, you can see its a little bouncy on launch.


someone asked earlier about the computer, its a stock PCM with Ford Motorsport 80# (90 something at 60 psi) high impedance injectors, tuned in Speed Density by Jim at SpeedINC
