Last night I did a little grudge racing against a buddy of mine with a 99 Camaro SS 6MT with the following modifications:
cam (cam is 224/224 .561/.561 114 LSA), SLP headers, LS6 intake, Descreened MAF, fasttoys ram air, air lid, K&N, cut-out with highflow cats, 10.5MM plug wires, NGK plugs, Ferrea intake & exhaust valves /w 3 angle valve job, ARE ported oil pump, subframes, Spohn torque arm /w front drive shaft loop, Moser 12 bolt with 4:10 gears, and Nitto DR's
The weather was very bad for running good times (90 degrees with 95% humidity) but it was fun nonetheless. He was having a hard time hooking up and I had some misfiring problems that really slowed me down in 4th gear (the car would buck pretty severly and I threw a misfire code)
Here's how the slip looks:
8.0309@ 87.75 1/8th
12.5774 @ 108.27 1/4th
8.3297 @ 88.37 1/8th
12.7447 @ 112.58 1/4th
I won, but it was close. Maybe 2 car lengths if that. To be fair, he did run a 12.58 earlier in the night. According to him, he was 2-3 mph and tenths off his usual times due to the weather and I believe him.
I think my car has an 11 second run (No Nitrous) in it with new plugs and good weather. I'm still using the stock rims and tires as well.
