So, just spitballing... Bear in mind, I'm largely uninformed, just things that I noticed from the race vid and the SRT dyno vid.
I don't do street pulls so I dont know the proper procedure (i.e., whether you just start in 2nd and pull through 3rd gear and it's over or what).
We all know that you want a direct as possible drive gear on dyno pulls for a good reading and that is usually 4th in most cars, not 3rd. I've seen a lot of instances where dyno pulls in 3rd (or any underdrive gear) would reflect a vastly different (and typically artificially high) torque rating. I dont know jack about the srt4 so I cant say where the peak of the torque curve would be on his tach but his revs seemed pretty low going into 3rd on the race vid and it looked like he would have nosed you out in another few sec. Could it be that his torque band is just higher up the tach (like a vtech) and entering 3rd at a low RPM made him lag? I'd be curious to see if there was any change one way or the other in the result if you were rolling 5 or even 10 mph faster before starting the pull.
Srt4's are best from 35mph rolls they really seem to shine and that 3rd gear is a monster in those cars.
Anyhow it took me a lot to b able to smash on my buddy's.
