Last time at Eastern creek I was only able to run 0.8 bar due to fuel pump issues and I would estimate, based as dyno figures seen quite soon afterwards, that I had, as a peak power figure, around 220rwkw.

Apart from the R34 GTR's I overtook around the track due to skill, balls and semi slicks, one particular incident comes to mind.

I've come onto the straight about 2 car lengths behind and at equal speed as an R34 GTR that had been tuned by CRD the day before and had, I think it was 253awkw, could have been rwkw.

Now what I want to know is; how come I was able to catch him down the straight? (not saying it was easy)

I have no reason to believe he was holding back at all.

His car mainly stock, pfc, zorst and boost.

Me, GCG highflow turbo, the normal bits.

Semis, the great equaliser:thumbsup:

The NEO engine is a good equaliser as well, especially if you have the usual bolt ons it would mumbo pretty well. Still good effort and im guessing you would have been entering the straight a 130km/h whilst he was in the ball park of 120km/h???? And you would have been able to brake as deep if not deeper for turn 1

Um, guys dont forget he's carrying a little less ballast in the GT-t compared to the GTR. I was going to say power was similar, but a re-read showed that i was dyslexic for a bit, thinking the GTR has 235 not 253 :cheers:

Um, aerodynamics? Gearing? You're just cooler? Loads of possibilties :)

Nope, everyone knows GTTs are just faster then GTRs in NSW :P

My guess is the power was similar but your faster speed onto the straight paid off...its very hard to make up for speed you lose at the entry to a straight ;)

I guess I could have come onto the straight 10kmh faster. I wasn't really referring to braking but yes, I braked later.

I wish I had 4 gears under 1 to 1 ratio instead of 2.

Ben - GTR badge???

Perhaps my car is lighter. What does an R34 GTR weigh. Maybe he left his spare and stuff in the boot but I didn't.

Maybe, but i doubt that woudl be it unless he is shifting like a grandma. The std turbos would be responsive enough to grab a whole lung full of boost as soon as he jumped back on the loud pedal...especially when you factor in the auto slipping into the next gear and as you touch on less range of ratios.

Perhaps the GTR owner was very much aware that he was driving an 70k car at the track and was driving it with the level of respect it deserves...or perhaps if you take the badge off the GTR is just another car whose performance down the straight is hp/weight:)

I think, it's all about power to weight issue plus You have aftermarket turbo Abo Bob.

It's not surprising for me for a gtt with aftermarket turbo to overtake gtr.

Plus, as far as I know at high speed, gtst with aftermarket turbo can keep up with gtr.

But I might be wrong, I just want to add my opinion.

Another thing, probably you are crazier when it comes down to cornering and the GTR driver scared of you and back off (HAHAHAHA)

:) j/k

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      After market rear camber arm adjustment

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      After market rear camber arm adjustment

      By Duncan · Posted

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      After market rear camber arm adjustment

      By V35Newbie · Posted

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.
