track night with the obx headers
just got back from the track very happy with my times
heres my best slip
reaction .355
I1 2.283
I3 9.34
ET 14.3
mph 98.8
i have an 03 cl-s auto my mods are icebox and obx headers and a set of es 100 tires
i ran a couple of weeks ago without the headers and i got a 14.89@96.xxmph
i didnt think the time would go down that much with the headers, but im sure with a better 60ft i can get a 14.2- 14.1.
what do you guys think

I went from a 14.5 to a 14.2 and from 96 to 98. My short time is better than his though. I hit 2.1s on both Intake only and I/H runs.

no matter how hard i try i get a 2.28 -2.30, with a 2.1 i should be at like 14.2 to 14.15
is the tire width make a difference cause my dimentions are 215/50/17, mabye i should have gotten 225/45/17

225/45-17 would help. they're wider plus a little shorter.
