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

[Guest INASNT]

rev if u came down to vic i would let u drive my car and see what time u got, just to see how much the drivers skill matters.

As an example if mario actually drove his car on the strip i dontthink he would be doing low 9's.

[rev210]

INASNT,

I'll take you up on the offer. You need to find a private road perhaps and play around with the launches to get it right.

I'd give a 2000rpm hill start kind of launch a go because it sounds like most people (myself included) get a little exited and floor the acellerator too early.The accelerator needs to be 'fed'.It's not much of a skill at all, you'll see what I mean when you get it right.

rev: i was trying a couple of times with more restraint but everytime i have done that i have got a slow time. I was launching at about 3000rpm then "gradually" (at least not putting foot to floor after the start) flooring it out to 6500 on 1st.

I have had plenty of practice on err, "private roads" just practicing launches. i guess you need to practice with the helmet on to get it right. With helmet and without helmet are totally different experiences.

For the record.. i have no probs with anybody driving my car for a run to see what it can get and the next meet I take my car. If anyhting, then it might give me motivation to learn better technique myself.

[rev210]

I think on the 'slow times' you may have launched with less revs but, still hit the full throttle too early and instead of spinning the tyres you 'bog down'.

The idea at the strip is to launch like a fast trafic light launch. It's not full throttle till you hit the end of the lights on the otherside.

You can still travel pretty quick with 3/4 throttle.

hi guys,

Over the weekend i did a [email protected] 2.183 60`.I`m running stock turbo-BOV-ECU but i have got a FMIC,boost bleed valve,zorst(turbo back),pod filter,255rears,9-12psi depending on climate.A couple of months ago i had it on the dyno and got 204rwkw(no dips).

rev210- The only reason why i posted this is because i noticed your car is a 1995model and so is mine.Maybe theres something in that?

REV210 i noticed that you have adjustable timing, i have just purchased a LT-12 microtech for my R33 could you give me an idea on the timing you went for so i have something to go off. Such as total advance at what revs, flattens out to ___ at what revs and how maney degrees retard at what boost, and mayby even what advance at light throtal vacume. Anything would help i think you said 20 deg total so im estimating 30 deg flat from 4000 revs and 10 deg retard due to 10psi of boost. :uh-huh:

[BOOSTD]

Do a search for Power FC mapping. I posted my entire map.

[Roy13]

This looks great! Exactly what i,ve been looking for. Thanks for your help. Going to go out very soon and try them out. Having a loot of trouble with the idling side of things to, maybe i'm too lean, seams to idle well but when backed of to idle, drops way to low!!

[BOOSTD]

Disregard my ultra rich idle mixtures as I had and air leak that I compensated for. Found out air was being sucked thro my catch can in to the plenum bypassing my air flow meter and butterfly. Clean your AAC valve, its the thing hanging of the back of ur plenum closest to the fire wall. you will see two plugs, the purple one is the right one. This usually solves most idle isues.

[turbomad]

Why is your catch can connected to the plenum, mine is only connected to the two rocker cover fittings.

[BOOSTD]

mine is connected to the rocker cover aswell- however

there is another smaller pipe with a valve that closes once on boost that comes out of the rocker cover on the plenum side and goes into the plenum. I blocked off the valve with a screw and now I have perfect idle again. My catch can actually works now to, has about 10mm of condensation and oil after a week. Previously had next to nothing. Wouldn't suprise me if other people have made the same mistake.

[rev210]

matt,

I can't adjust my timing per rpm point. I can only set 'base timing' like all stock cars. I have no idea what it really is. A re-graph of timing is a great idea if you have an aftermarket ecu, lots of engine response to be gained.

the 13.44 is a good time. I wish I had 255's like you instead of the 205's, my last run down the 1/4 got me a 13.3 and a wheelspin fest launch of 2.3. I don't know if I'll get down past the 12 barrier with the 205's .

[Guest MFX_R33]

BOOSTD, that info on the catch can sounds like it is exactly what has been happening to my car. Cause thinking about it now, I have clear hoses throughout the engine bay and the one to the plenum from the rockercover is black, and the catch can hoses have never had a drop on them. I have also had alot of problems with stalling on back off, which were previously written up to the size of the throttle body.

Thanks heaps, as soon a I finish this stage of mod's to my car and eventually get it back on the road I will try that.

Jeff.

[BOOSTD]

MFX_R33- Nice one !!! Its always good when you find stuff like that. Guess what.... I got 460km from a tank instead of 370 after fixing the leak. I'm on my second tank full now and have 310 km on the clock and just under 3/4 of a tank left! The car is ten times smoother now around light closed loop throttle aswell. I think because the closed loop operation works so much better without a leak that the car doesn't understand explains my new super economy. Don't forget to remap your light load points.

The valve you've blocked with a screw is the PCV valve (Positive Crankcase Ventilation) Not much point fitting a catch can if the PCV valve is still operating as intended Except for looks.

what quarter mile should i get on my car ?

95 r33 gtst with series 2 engine (no ignitor box)

Cold air induction sectioned off in engine bay / k&n filter

supra round core front mount intercooler

hks suppa dragger exaust (3")

VL Turbo T3 high flowed with T4 front wheel running 10psi

standard suspention with 235/40/18

standard computer

apxi twin chamber BOV

Automatic dif (4.3:1 instead of the standard manual 4.1:1) with 5 speed manual installed (i get a few seconds in 4th gear)

If my speed meter read a 13.02 quarter & 4.71 0-100 would that be a fair call to go by ? or would it be wrong ?

are you guys finishing the quarter mile at the end of third ? or just as you clip into 4th ?

[BOOSTD]

Only one way to find out. The standard computer will be holding it back tho. Let me guess, when the wick is turned up past 10psi ur mixtures go ultra rich.

[Guest MFX_R33]

Guilt-toy depends on how well you drive it.

Boostd, my fuel economy also went to shit, although I only get around 250k's out of a tank.

I can drive it goood... would a 12 be possible with those mods?

[benm]

in the distance future probably, but you'd be best off aiming for a 13.5sec first off.....
