Hang on a minute.....he (Nismoid) has come into this thread and made a smart-arse comment. Paul has explained fully what the situation was, even offering the dyno operators number (not our tuner) if he needed it clarified.......THEN he has come again with another smart-arse comment (world leader crap) So Paul has returned serve....and good on him, are we supposed to sit here and cop it. He doen't need to put up with that crap. Here's a copy of the result and the dyno operators number if anybody wishes to call him for further questions. We are just about over this whole SAU thing.

Someone had to take over from the SST brigade, didn't they ?

You are getting offended by your own words. World leader has your trade mark on it. So, can anyone get a world leading build and performance...? Perth was too far to drive but Sydney is much reachable.

Please do not leave SAU.

well my AFR is flat on both Jim's dynos.... and the dyno at the GONG...

maybe it is just a sensor thing, I would hardly imagine the car is actually tuned like that AFR, as it is not consistant with the other information... i.e. the smooth power curve or the other dyno sheets I have seen....

12-12.5 still seems ok to me :rolleyes:

oh and don't stress Stace :rolleyes:

two.06L - let's settle a few things here once and for all... I think I speak on behalf of many people when I say that the 466rwkw power figure seems a little high for turbos that are rated at 640hp, yet your car is claiming to be pushing 624 hp AT THE WHEELS... And apparently you haven't even turned the boost up!!!! Can you find any logic in what I'm saying??

I'll ask you a simple question, do you think there is a difference in dyno figures when conducting a power run in 'shootout' mode and 'non-shotout mode'??? I have done a comparison with my car (see here: http://www.skylinesaustralia.com/forums/in...opic=78364&hl=) and have noticed an increase of around 10%.. So that's why I'm asking if you have a dyno graph in 'non shootout' mode, to make the figure more believable.... My car has 365rwkws, but 396rwkws in shootout mode, does that mean I should preach to the world my car is a 400rwkw monster???

Just have a good think about it...

For anyone thats interested the two Dash 7 GT28R's come up almost line ball with the GT3540R in 1.06 ARR turbine housing form for compressor and turbine flow . The GT28R's (2860R's) have a little more turbine efficiency (75 vs 72%) and flow a little less at lower exhaust gas pressure ratios .

I think HKS GT-SS's use a slightly different comp wheel and the maps would be interesting to compare .

Non-shootout mode can be configurated by the dyno owner/operater, so it would be rare to get a conservative figure in that mode. I don't think Ben @ Racepace has any sort of ego regarding impressing customers with large numbers, and so has his kit set more realistic.

2530's use a T3 comp wheel that peaks @ 35lbs/min, theoretically twins are worth 70lbs/min or similar to a T04R/Z - T66 turbo flow wise.

p.s. my dad can still beat up my mum.

TommyK: Have all your goodies been installed and a final tune performed? If so, do you have a dyno sheet you wouldn't mind posting up? IIRC some of your modifications are very similar so it would make an interesting point of comparison.

dont know bout these 'so called' european performance cars...

FIAT stands for:

I never thought my European car was a "performance" car :)

BMW: Brings More Women :O:P

You know, the money-grubbing, self-absorbed and ego-centric kind :D

Lucien - I do believe I posted one up a while ago. Check for posts by me in the NSW section.

Mind you - I am not happy with my CRD tune. The car is laggier than i would have expected with these turbos. I am going in to BEL tomorrow to get a road tune done. Full boost @ 4800 rpm in 4th is comparable to Mik's tune, and he's running GT-RS turbos :D. Not happy!

Will let you know results tomorrow (hopefully)

Sorry, what I meant was: I remember you saying that the cam timing needed to be played with (and, IIRC, there was also some issue with your boost controller). Hence I was wondering if those issues had been corrected and a dyno done.

Seems like all will be answered soon anyway :O

Tommy k,

This is the 1st negative feedback i've heard from crd's tuning...you need to remember that the gtrs turbo application is top end power. gtss is better for mid range.

Just so you know - I have the same turbo setup on my r32 along with the typical mods i.e. pfc, cams etc.

I can honestly say that crd are the most reputable gtr tuners in nsw & possibly aust - my results were amazing :O

Marko.

      George's R33 GTST build

      I would paint match the whole thing to avoid unwanted attention  I had a similar bonnet, paint matched, on my old R33 GTST, but mine was a fibreglass jobbie made by Blitz in QLD, they work extremely well for radiator efficiency and under bonnet temps

      Does anyone run this kit with factory plenum? Does the adapter and bosch tb fit under factory strut brace? I wanted to get this setup before going forward facing manifold. Thanks

      George's R33 GTST build

      small update time, after always wanting a "cool" looking bonnet for my car and always struggling to find one for the series 2 that i liked and wasn't an insane amount of money. Saw one i liked on RHDjapan from D-speed in Japan the price was very good for a carbon bonnet so good infact i was a little unsure how much i trusted it, decided to bite the bullet and with the help of jesse streeter in not long at all it was at my door. Once it was delivered i ran in from work and quickly unboxed it and to my surprise the quality was actually pretty good i quickly removed the old bonnet and placed on the new one to test it out and even the fitment wasnt too bad at all. Then decided to paint the little grille in the bonnet black to stop it sticking out so much.   I decided to not mess around with the hood latch and just install some aero catch hood pins, having never installed them before did some YouTube university classes and i was good to go. fair to say it is not a fun job at all from making brackets so the pins sit nicely and actually cutting through the bonnet but also being very scared of cutting the holes too big it took wayyyy longer than i would like to admit but finally got it there. Then it was time for a quick test drive to ensure the latches actually worked and thankfully the bonnet looked very stable. I still think paint matching the bonnet and leaving just the part that sticks up as carbon would help make it all look alot neater as im not sure how i feel about all that carbon on a very fridge white car but will leave it as is and see how i feel with time.

      Mistakes were made, my R34 Story

      I think it's bound to happen, you finally get it all perfect, and bam, something will happen. I took a while to get a Commodore rear quarter repaired where a P Plater clipped it. Two days after getting it back, Sarah wiped it out on a concrete pillar in an underground car park... This is why I take forever to repair them, it stretches how long until it gets bent again... 😛

      Nah, not really responsible for that little fiasco, but I'm still pissed at myself for writing off my 86, or when I reversed my VX into a pole just before selling it, but, meh, 5hit happens to stuff, all it takes is a slight distraction, and life is full of distractions, and "dooh" moments
