Hello guys, Took the Z to the dragstrip yesterday, and didn't run as good as I had suspected. First off, I am in Wisconsin, so the temperature was about 60 degrees with about 50% Humidity. My car is an '03 touring; manual transmission with the following engine modifications: UR Pulley, Jim wolf Pop-charger, Crawford intake plenum, Kinetix unresonated test pipes, Ultimate racing Y-pipe, japtrix b-pipe, stock muffler. I don't have an ECU reprog. yet (this may be the key).
The best time I was able to achieve was 13.9 @ 100 MPH
60 foot was 2.16, and 1/8 mile was 9.05
I was expecting mid 13's at minimum. The tires are BFG g-force KDW's in a 275/40/18
What do you all think about this prelim. day at the strip?

 

Yea man seems slow, i ran a 13.8 @ 102 with just the pop charger, 20psi in rear tires and fumes in the gas tank. Id do the ECU reprog. ( i have 03performance/manual and live in FLORIDA) so you gotta run faster than me.

 

I would like to see the time slips. Thanks.

 

hey i did 14.1 at 100, and i just have nismo exh, UR crank pulley, injen cai. half tank 91 oct. and i dindt burn my tires. and also i had 40psi in the rear tires on 19s. i know if i just lower the psi and do a good burn out ill hit 13.8 or 13.9. and i took out my spare.

 

Considering yesterday was a cr@ppy day at the track in the midwest (I'm assuming you went to GLD), I'd say your times are pretty decent. The DA was around 1500ft yesterday due to the low pressure. I was trapping a couple of MPH low and so were most of the guys I was with at Byron (south of Rockford, IL). Get back to the track on a cool day with high pressure and run it again. You should see improvment.

 

run your car till E light comes on, fill 2 gallons of race fuel 100octane/ not 110burns to hot unless mixed with about 2 gallons of lower grade., rip out the spare, drop your tire pressure to 20psi, and wait for a cool night and I promise you (if you can drive) you will hit 13.5-13.8
