13.4 second 1/4 for your 'stockish' R33. (A how to guide).

i got a 13.981 at calder last night... could have probably done better, but happy for a first real strip run. Set my 235/45 tyres to 16psi and I have pineapples on the back - seem to have less traction probs than some of the other gts-t boys who also ran.

What mods do you have??

[predator]

a few its not really "stockish" though as the thread indicates...ah well..

S-AFC, cold air intake, dump pipe, hi-flow CAT, HKS Super Dragger II cat-back, blitz pod, HKS FMIC, ProfecB EBC, heavy duty clutch, pineapples, zeal coilovers, falken 235/45R17.. stock ECU, stock Turbo @ 13psi

i think some heat buildup and trying a bit too hard could have effected my later runs.. i'm gonna wrap some of my piping soonish to maybe fix that for next time.

[rev210]

hurray another 13sec GTST!

good time with an ordinary mph. What was the60ft?

[predator]

thanx other runs were around mid-14 at higher MPH (~100).

Its all in the takeoff, which i'm sure you know, but its definitely what I found out on friday. The difference between a 14 sec run and a 13 second run is all in a good takeoff.

Easier just to just post the timesheet with the 60', etc.

If I can get that a bit lower (which I think I can next time), I think I may be able to get about a 13.6 or something with a perfect launch and my current mods. I'll be happy with that until I one day I upgrade the turbo, ecu and maybe a couple of other things which should push me into the 12's. 12's for a daily driver that is RWD would be pretty nice I reckon

anyway, enough about me.. back to general discussion

[rev210]

Well the takeoff is good. 2.1 60ft is fine.

Getting lower is hard to do.

The 13.4/.5s I did were at 2.1 also. Looks like you are losing something up top, rather than launch.

[predator]

yeah.. other runs were worse launches, but better shifting after that, resulting in higher top speed of around 101mph

If i can pull both off in the one run i'll get somewhere around the mid-13 i think as well.. tyre pressure could have been a bit low @ 16psi for street tyres??

[Guest MFX_R33]

I agree with rev that is a very good ET for your MPH. I don't know if gear shifts are going to make much difference though cause if you botched them badly you wouldn't have an ET like that?

Jeff.

[giz01]

Only 95mph for a 13? WTF this is 4wd mph! My gf's sx ran 2.16 60ft time with 102mph for its 13.75.

[riggaP]

I ran 14.370 @ 98.79, 60' 2.407 with a pod (no cai) and a 3" cat back zorst. I believe that 60' time could come down a few tenths with a bit of practice (I only had 3 runs on the day).

I just dont get it. predator666 you've got some decent mods I'm guessing they'd be around $2k rrp? Surely to goodness your $2k mods are more than 0.3sec better than my $400 mods? It looks like you can launch it better than I can also.

A question for all: How much did you spend (and on what), and what affect did it have on your times???

[predator]

Most of the stuff came on my car.. but if u added them up prolly $6000-$7000 or so read back a page for the full list. 0.3 is a reasonable difference.. and 1 second is a massive difference in terms of what you need to do to your car most of the time.

That run i felt like a pretty perfect launch, and i took it a lot more easy on the gear changes afterwards. Maybe i backed off right at the end? (no idea). Anyway, its all in the timesheet up above, i'm no expert, and i don't remember every single detail! I only had about 4 runs.. next time i go, i'll hopefully have some more runs, and hopefully get a better time as a result of the practise.

[NismoR34]

Pred: one question, did you warm up the tyres with a burnout or not?

I would prefer not to personally.

[Guest MFX_R33]

Waming up your tyres with a burnout is good for show, but not really going to help you on street tyres.

I ran at eastern creek again last night and got a 13.102 @ 108.46 mph, killing my old time of 13.7 @ 105. I was much happier. My 60ft this time was much better, of 2.114 over 2.365.

I walked away grinning from ear to ear (I was hoping for a 13.4) :) .

Jeff.

[NismoR34]

That is impressive Jeff, well done!

More importantly what is standard on your car? Turbo? IC?

I assume you are running street tyres on those 18's?

Just curious...

[Guest MFX_R33]

I have standard internals, injectors and fuel pump. I am running a custom plenum, XF trottle body, FMIC, EMS management, high flowed turbo (metal wheels, no bb centre), running 17psi boost, exhaust, etc.. The tyres are 255/35R18 Fulda street tyres let down to 20psi.

Here is a pic of my engine bay,

[Guest INASNT]

great time jeff!

your stock fuel pump and injectors must be near maxing out

[Guest MFX_R33]

They are close but still handling it. We have looked at them closely on the Dyno, but they are still upto the task at the moment. I am looking at a bigger turbo at the moment, so I will have to do something about the fuel system soon.

[benm]

what sorta rwkw is it making ?

[Guest MFX_R33]

It is currently making 205kw at the rears.
