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

:D

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 :D 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.

      R34 Diff oil

      By Duncan · Posted

      Only thing I'd add...is on recommendation from a good diff shop, I've used mineral oil in my diff including the race car for years. The synthetics can be too slippery and glaze the gears

      75W90 GL5 is fine. If you aren't sure about the type get one with LSD additive.

      Short shifter r34

      By Kinkstaah · Posted

      Because you're effectively rushing the shift and forcing it to go in - with greater leverage against parts that don't _want_ to go together. Short shift = forcing the gear in harder. Also Redline Heavy Shockproof actively says not to use it in anything with Synchros. Well, it says "not recommended" which is basically as far as anyone will ever say in a product statement to "Do not use" Generally the Redline makes the gearbox feel great... until it fails faster. https://www.redlineoil.com/heavy-shockproof

      R34 Diff oil

      By Kinkstaah · Posted

      99.9% of them are viscous diffs. The 0.01% are helicals. They were only option-able in the series 2, as well. I have redline heavy shockproof in my helical. It seems... fine? I don't think anyone is ever going to know until something really breaks and at that point I'm not sure anyone will blame the oil. I just chose it because it's extremely heavy duty and my car will see not-road-legal duty for it. I've also had sadness with various diff oils in the past sweating out everywhere and/or other 'fun' things, with clutch diffs. Given you have a 1.5 way on the shelf, I'd not even bother with the diff in the car and just get to tinkering with it. I would spend the $90 on oil toward the labor of someone else putting the diff in if time poor even lol.

      R34 Diff oil

      By drifter17a · Posted

      I believe mine is helical and not clutch type. During drifting one wheel was spining as if it was open diff so bought kazz 1.5 way and has sat on my shelf for the past 5 years as I want to learn shiming process and do it myself   in meantime thought I change the diff oil hence post here. So any 75-90?   i am pretty sure r34 are helical not clutch lsd as standard . That is gtt ones
