Traction control/PSM off will reduce times by more than .5 sec. Before that dawned on me I was about a full second off and made me really wonder.
I didn't want to beat up my clutch too bad, but slipping it slightly is quicker, however not as consistent.... so if you want uniform results, dumping at say 2500 might be the way to go and hammer it to redline.
I could pretty much duplicate published times with full tank, PSM off, 2200 launches with some slip, and redline shifts.
On one lauch, I revved it too high while dumping the clutch which resulted in severe axle hop all the way to redline, it was so violent my full coke-cola jumped out of the cup holder and onto the seat! Thank god it wasn't opened yet
That run got me a 10.XX ET 1/4 mile
My best real time was 5.579, 0-60; and 14.031, 1/4. I could've shifted a hair faster, but I don't like abusing the equipment. If I drove it like I stole it, I suspect I could take another .2 sec off.
