I have a 99 WS6 M6 with a lid, cat-back exhaust with no muffler, fast toys ram air, TB bypass, SLP smooth bellow, Pro 5.0 shifter, K&N filter, NOS 5177 kit with a 100 shot, Kumho Ecsta Supra 275/45/17. I went last night and ran the 1/4 at Indianapolis Raceway Park and wasn't too impressed with my times. I was wondering if anyone out there could help me out.
Without NOS
60 ft.-2.234
1/4-13.81@103mph
With NOS
60ft.-2.205
1/4-13.37@107mph
I was hoping for more than a half second improvement from the 100 shot but some of this could have to do with it being my first time at the track. Any help would be appreciated.
