I cut a 1.92 on Michelin Pilots with just C springs and sfc's my average 60' is 2.0x but my clutch takes a beating for it. I normally have to rev around 4,000-4,400 and ride it out any lower and I bog and cut 2.1x or 2.2x's...
Jackie maybe you can explain this...My best run is a 13.82 with a trap of 97mph but I've gotten 2 or 3 13.9x's with trap speeds of 102 and 103...I know I need to be more consistant with my shift points but it just doesn't add up to me as I don't see my car pulling that much power to trap another 1-2 mph faster than my averages which is 13.9 to 14.0 with 99-101 mph...if you guys need the timeslips to see the info better let me know I'll go screw around with my scanner and get them scanned in.
edit: ya oops I didn't notice this was a older thread
