Went to Englishtown tonight. I ran my car with Intake and headers and 55 shot of nitrous. First run without Nitrous was a 14.7 I used nitrous on the second run, 14.2 Finally i hit a 14.0 with a nice launch. The question is, how do people on this forum run 14.2 with just headers and intake? I have OBX headers, are they really that different than the comptechs. I was running 14.7 stock and after headers and intake, im still running 14.7 Theres gotta be something with the headers or my car is not ment to be modded. But 55 shot did knocked off .7 of a sec, and i was surprise.

 

was that first 14.7 with the system and 19s on?

 

oh, i took out the subs but i left the 19s on. the 19's dont make a different since they weight the same

 

actually they do make a difference. its the rotational mass. the closer the weight is to the center of the hub the better. on the 17 the weight is 1 inch closer than on the 19. doesnt sound like much but it does make a difference

 

i also ran the car with the 19's on before, with intake only. same time 14.7

 

but have you run it with the 17's? and temp will play with your times too
