was it really hot out. where u getting good 60' times? different track?

Re: slow 1/4 mile times (ek_kid)
Any Cels? and what condition is your clutch in? Octane rating of fuel you were running? there are alot of variables that would result in such a crappy time. And yes those times are crappy.

reaction time has nothing to do with 1/4 mile time... You can sit at that light for a minute then take off and still run the same 1/4 mile

Eleventeen billion million trillion percent Correct. Its funny how people rush to get out of the Hole thinking that they will be faster, but in fact they probably mess up there launch, get way to much tire spin, cause they dont concentrate on driving.

sorry to say, but 15.6 would be horrible in a stock Si less all your mods.
once again, DRIVER ERROR you should be in the 14's with those mods.

Re: slow 1/4 mile times (BauleyCivic)

maybe cuz you have too many headers on your car
plus, stock si clutches suck, maybe with the more miles you've put on the car since you've last run it have made it worse.

yeah, take off some of those headers!
on a serious note, it is probably driver error. try letting a friend run it down the track.

Re: slow 1/4 mile times (Mattssi99)
Reaction-.556
I1-2.612
I2-7.017
I3-10.569
I4-13.605
E.T-16.188
MPH-87.409
With that run I had a better 60 foot time than the other car, it was ran at sacramento raceway the same place as the 15.8, 91 octane gas, yes stock clutch, it was the 2nd of three runs all in the 16.1 range, if I dont know how to race then atleast Im consistent. I usually dissconnect the negative cable and let the car run at idle for 15 minutes after each mod.

Re: slow 1/4 mile times (jameskersten1)
yeah... my d series puts like 93HP to the wheels and I can get 16.8, so I would definately blame the driver. What tires are you running?
