i ran my best 16.163 @ 86.678 mph...2.583 60ft
with a monster flow filter and custom upper tube and wheels

i've only been to the track once

 

Your 60' is really high. Once you drop to 2.2's, you should be in the 15.6 - 15.7 ranges. Being that you have an intake, I'd imaging you should be 15.2's to 15.3's

Make sure you drop the cars weight:

Remove the spare and any other stuff you may have in the trunk.

 

2.22? 60'
14.8 @ 93.7

Frankencar intake, Don's VB mod, and heavier 18 inch wheels to slow me down

 

I think his car did pretty well for just having an intake. He didn't take anything out of his car either(spare, jack, etc.), plus he ran with the heavy 18" M5's. He didn't torque brake either, well he did, but I screw up at the line, so when we had to line up again, but this time he forgot to torque brake.

Nam, I think your car is quite fast as it is. Look at your trap speed, that's just one mph slower than me, and I ran a 15.6...weird. I should have probably lower my tire pressure, I ran with the street setting of 35psi all around. I think I should be in the 15.3 range.

 

If you have a y and an intake, you probably should be under 15.3.

 

hey mike.
i actually have 17s....and i dont think they're that heavy
maybe even lighter than the stock hubcaps
i really need to learn to torque brake and launch better

my bro jus got his wsp ypipe for his I30...we're installing it
tomoro...if it's good i might order one but wsp took over a month
to get my bro his ypipe

 

i havent actually gone to the track, but ive gteched it several times with some consistency....
Before any mods:
16.02 @ 89ish
16.09 @ 87.xx ?
16.11 @ 67 (had to start braking cuz of a cop )

-this is with myself and another person in the car, and the spare and jack still in there.


After intake w/custom upper:
16.02 @ 90 -i was so happy i could spin my tires that i was spinng for almost a good second
15.6 @ 93
15.3 @ 97....this was run by my friend, i verified it, wish i had a pic.....im gonna go to the track sometime soon, and ill get official times

 

how accurate is gtech? i was thinking about getting one, but
i wasn't sure how accurate they are.
if u got a trap speed of 93 and ur friend got 97...that's really high
for those times

 

ya i thought so too....that run was with just him (he is a few pounds light than me, no spare, no jack, all crap taken out of the trunk including carpereting, and he did a brake stand launch)

 

I have found that the gtech is very accurate on the track. It is not so accurate at trap speeds. On level ground (track), gtech comes w/i the advertised accuracy. I noticed that on the street it is very sensitive to terrain. I know that it compensates for that, but remember that's only at the time of take off. For example, you can try and get a time and start at the bottom of an incline and the gtech comps for that, it doesn't for the down side of the incline. I have used my gtech both on the street and track. Track is much more accurate at the ET but off on the traps by as much as 5mph. In my best run the gtech said 13.78 @107mph. I actually ran 13.78 @102mph (timeslip).

You guys should really post your times in the 'Timeslips' forum above.
