I be really interested to hear also. Next time I go to the track I think I'll let Ted try mine. I am in the same boat with the power as Jon. I did move my suspension setting to the middle point and my 60' time was the best all night. Still a 2.2 though. I am also gonna try the Performance setting next time. Other than that, I don't have anything to offer.

Maybe Jeff will chime in here, he ran a 1.80 in someone else's car in BG. That's pretty damn good.

Stock tires:
Avoid the water in the burnout box.
Do a quick dry hop to clean off the tires
Roll to the line
Stage
Vary your launches from 2.5 to 3.5 till you find the sweet spot, feather the clutch a bit out of the hole and nail it.

DR's
You can hit the water box, not necessary though
Do your burnout, 5-10 seconds to get a little heat
Roll to the line
Stage
3.5 and + Just find the sweet spot once again
Feather quicker and stab the throttle.

Each car will be a little different based upon the clutch. So some will like a higher launch or a little lower.

Yeah, Jeff took my pretty much stock beast (`cept straight pipes from the cats back and Marc chip) to a 1.8X 60' and a 12.75X qtr on his 1st pass

....I think he launched it at about 3500 rpm....car has gsd3's for tires.

launching with the light weight flywheel will be a bit harder than with the stock dual mass
