Help with improving 1/4 times

[HKS-R33]

I took my car to the NDSOC Drag Day at Heathcote on Saturday and the best time i could get was [email protected].

My car is a 96 r33 gtst and the only mods i have is a 3.5" HKS cat-back exhaust, custom 3" front pipe (no dump pipe), GTR Cat, GTR intercooler, K&N pod filter and a cheap bleed vavle set to 12psi. The tyres i was using was HANKOOK K104's 265/35/18 set at 37psi.

60' time = 2.1

660 time = 9.08

660 mph = 78.75

I am no expert in drag racing but i would have thought that my mph should have been higher by the end of the 1/4 mile and i should have at least cracked into the 13's. I have been thinking that maybe its my boost controller that letting my car down in top end, because im not even sure if it was hitting 12psi in 3rd and 4th gear.

Any help would be appreciated

Cheapest and easiest performance gain is weight reduction. Get a decent electronic boost controller...i recommend Blitz dual SBC (can get you a cheap s/h one). the 35 series tyres and 37psi arent doing you any favors either.

Engine management is your friend I'd also be turning the boost down to 10psi and heat sheilding the pod (if its not already).

Your 60' time is good, not outstanding but good enuff. The time is very good considering the mph. Is the power smooth up top?

Get yourself a lighter set of MAGS!

i've had the DTM racing blitz 18" as well on my car. and compared to stock (16"s) my 0-100 times were varying from 0.5-1 sec slower!

my car is a 96gts25t series2 as well and WHITE! hahah similar mods but more power due to bigger turbo.

Yeh i think the power seemed pretty smooth up top, i need to put heat sheild on the pod aswell.
