I have a question that I need help on. I was at the track on Tuesday night 4/5/05 in NJ it was 55 degrees great night I have a 1998 Max GXE 5 spd 18" rims Cat back exhaust, Injen intake, short throw, stage 2 Exedy clutch.It was the first time I ran it i was suprised what I saw I ran the car twice Once was a 15.9 next 16 flat my 1/8 mile was 69 miles per hour both runs but 1/4 was only 86 what is my problem It feels real fast to 70. I need some help on what you all think is the problem or what I need to have done it only has 70,000 miles on it.


ACTUAL RUN SHEETS


RUN 1 RUN 2


60' 2.315 2.408
1/8 10.17 10.293
mph 67.84 67.79
1/4 15.909 16.114
mph 86.33 83.80

 

1st thing 1st, check your codes for the ghost knock sensor code, if there are any others, fix them, lose the intake, and buy a y-pipe.

 

Damn if I had your 2.31 60ft last saturday I'd be running 14.9s. What tires do you have?

 

from your data, your high end is pretty bad. you need to install mevi+jwt7200 ecu. or else, go force induction.

another thought, your 18 inch rims could have been a factor, too. go for a lighter and small set of rims.

 

that is his biggest problem. put some 16 in rims and you will see a big improvement. i did a run with 18 in and a run with 16 in drag radials and the difference was a 1/2 sec or better easy.
