i did the 1/4 mile today
got 4 runs in
my best was 16.7
i was hopping off the launch though but its still the best run
i just have a full body kit with spoiler (weight), cf hood and spare tire removed, 17's on yoko avid H4's, dual 4" exhausts and SRI
that is all
it is a 93 VTEC prelude
i got upto 82mph
i did a compression test and it was 200 across all cylinders
so what do you think could it be? i mean even with a good launch it was only 0.2seconds slower to 60'
something is up with your motor or your driving skills. my car ran better with more weigh in it. and i only had a F22b in my car. check everything out, i mean not even an AUTO h22 should do that bad.
what do you mean by good driver?
i can shift faster then anyone iv ever seen.
i just take it upto about 7100 and then shift.
don't think my hand can move any faster then that.
i dont get it, when i run at a 1/8 track on a cool night, i run 10.2's consistently, but when i run at a 1/4 track, my 1/8 times are 10.0 consistently.
but, the main "problem" that you have is shifting too low for a vtec. they are made to run to 8k on the tach (its offset a little) and they love it too. run it up to atleast 7.5k before you shift, 8k if you want.
i don't even get into 4th gear
i get it upto about 7600rpm at the end of the track on 3rd
after about 7300 rpm its floating
not making any power at all
sooooo shouldnt you shift at peak power?

Noooo no non no no no...
You want to shift where you will keep your overall power highest.
If you drive passed peak power you will get reduced power obviously, but the power right after peak is so much higher than the power in the next gear at that speed. If you dance on your fuel cutoff then when you switch gears you are at a higher point in the powerband with vtec engaged. I don't have vtec myself but I am under the impression that the goal with a vtec car is to be in vtec the entire 1/4.
hahah man i would shift at 7k on my f22b all the time you just gotta shift a whole lot higher. hahaha, you gotta drive your car a little hard man, if you want to get good times
i m not too familiar with vtecs, but wouldnt that dual exhaust be a problem ? i mean, i dont know what you got all done, but i dont think you got that much power to need a dual exhaust, that could be your problem IMO. I have hardly seen dual exhaust on a 4g, you are probly the 4th or 5th one i see with that. And the last one i saw around here with, i beat in my Si, dont know if it was vtec or not, but it was hella slow, not worth wastin gas over.

yes this is exactly right, shift past the high point so that when you shift the rpms drop to just below the point where you will make the most amount of power. this way you can immediatly hit the powerband again... and again and again and again
^^^ good to see someone shares the same opinion as i do.

The dual exhausts are hurting the performance, but would it be significant enough to yield such low times? Can it cause that much of a decrease in power?
Your 60s are horrible, even if you were hopping BADLY.
As previously stated by others, your 60 ft times are horrible but may not be entirely driver fault. Such horrible times may be indicative of a broken engine mount, at least that was my problem when I went through a similar problem, although my trap speed was not as low as yours. With age and wear the mounts will go out, so check them out or have somebody qualified do it.
