Slicks or drag radials? Suspension mods to get it to hook? And I'm going to assume a very well prepped track.

This isn't apples to apples if the track got no bite.

Marshall, will chime in I'm sure, but he's running Bogarts on a 255/50R-16 DR tire... The standing joke is that PIB can "HOOK on ICE"

For my A4, I got my best 60' times loading the converter slightly and then flooring it on the third yellow.

I have tried pushing the RPM higher but I would red light more often than I liked.

A little different combo, but the same results. I haven't tried leaving higher than 1600, but 1.59 best with SS3600 Yank, 3.42, and Hoosier 245/45/17 drag radials. 11 teens at 121-122mph.

From the data logs in HPT, it's clear that the converter flashes right to 3600.

I'm headed back out to the track Sunday....I'll be sure to post the results.

I'm airing my MT DRs (275/40/17) to 17 PSI cold and flashing the converter to 1500-1600.

Wish me luck.

11.552 @ 115.45 mph for me this weekend. That was with a 1.616 60 foot time. Looks like I was right around 2300 at launch. I know my MPH is low, converter drop of 800 rpm.

Stall it as high as possible without creeping forward. You may have to really stand on the brake. Let the car shift automatically. However, if you have the ability to reprogram your shift points then you should definitely experiment with the shifts. I picked up some nice gains with minute adjustments.
