I cant believe it... I'm trying to crack the 12s with the combo in my sig (stock motor, 5-6psi, FMU, 10* base timing spout in) before I start trying to maximize my combo and start adding the parts I've been accumulating. Last night at the Pacific Raceways TNT out of 4 runs I had three 13.0X runs...
I'm running MT 235/15 DRs with smokey 2nd gear burnouts. I have been messing around with tire pressure and launch RPMs. Last night I was trying between 16 and 18 psi.
First run I blew the tires away on a 3500RPM launch to the tune of a 2.3 60'. I have never had them go up in smoke that bad before which really screwed me up for the rest of the night...
Second run I was trying not to waste another run going up is smoke again(especially after waiting over an hour for "the sun to go behind the trees") so I dropped my RPM to about 3250. This time I bogged bad and pulled a 1.960 60' for a 13.02 ET at 107.5mph.
Third run I upped the RPM to about 3500 again (should have gone higher but I didn't want to waste a run) and bogged even worse to a 1.964 60' for a 13.03 ET at 107.9mph.
Last run I decided to try a 4000 RPM launch and slip the clutch a little more than I had been. Bogged the worst yet to a 1.969 60' for a 13.09 ET at 107.3mph. I blew off a vacuum line somewhere at some point on that run and it was already dark so I couldn't find it. So that became my last run.
Man.. I was so close. Last time out I pulled a 1.8 60' (weather was worse though so my trap was down and ran a 13.06). If I could have hit one of those last night I would have been all over the 12s but that first damn run screwed me up.
Didn't make my goal but at least I was consistant (even though I really didn't want it to be)... three back to back 1.96 60' runs all with 13.0X ETs and 107.X mph.
