Okay, this is seriously a newbie question, but I have just put my new stock R33 GTS-T through a dyno to measure the initial power before any mods were done to it.

Why is the max power only at 132kw instead of the 180kw which it was supposedly able to do in the official R33 specifications?

No wonder it felt kinda slow. Kinda dissapointed and can't wait to fit some mods. :laugh:

all figures in magzines, flyers, brochers, dealers etc are all flywheel

ie: at the engine / clutch system and not at the rear wheels.

a stock gtst in 4th will make around 130 to 140rwkw.

all the hsv's that have the 250kw badging and "figures" are all the flywheel

so they would make around 200rwkw. a 200rkw skyline would smoke it no worries

The R33's come with a dual stage boost control solenoid that switches from low to high boost mode at roughly 4500rpm (about the same time the variable inlet cam kicks to advanced setting). It's mounted in front of the passenger side strut tower with 1 hose going off to the intake before the turbo, then another with a t-piece splitting off to go to the wastegate actuator & the intake after the turbo.

Why nissan set them up with the dual stage control like this I have no idea, makes the car a lot peakier to drive though. When you get another boost controller you can set it up for the same boost at lower revs. Far more Torquey

Mate, my R33 was on the dyno at Mercury a bit over a week ago and it made 149.4rwkw, again on a completely stock car. If you compare the graphs you'll see that i'm making around 20kws more through most of the rev range, but more importantly you'll see the difference in boost. I've grounded the wire going to the boost controller so it's in high boost all the time, but yours should still get there in the end. I'd be looking at your boost controller first, maybe read the thread on staying constantly in high boost mode and give that a shot.

My RB20 made 196.4kw with some small mods. I think the R34 Turbo made a big difference. Dyno Results are on my Signature. Shoebox I suggest you get rid of the Dual Stage boost and just run a constant 8-10psi. >_<

:P

and it should be at 5psi before that. i'd say you have a split hose of something causeing a boost leak.

okay, i'll ask him about it tomorrow. split hose!?! don't scare me! =_=

but i really doubt that it's a mechanical fault, as i sent this car down for a pre-purchase inspection a few weeks ago, and it cleared except for an oil leak from the tappet covers, castor bushes which are about to split and spark plugs which are one heat range lower than they're supposed to be.

      Hey Nismo, any chance in the world you still have these seats?

      I'd say closer to OG GTX3582R, just smaller trim - so 59mm inducer/82mm exducer as opposed to 62/82 for the first gen GTX3582R. Yeah EFRs were boss, the EFR8474 is still an absolute beast and it perplexes me that people still go to things like Turbosmart/Garrett etc when the results people are getting with those are pretty unremarkable compared to what you could get with a turbo available well before those options came out.  DriftSquid (I think) "upgraded" from an EFR9174 to a Turbosmart turbo and promised a comparison video - and kinda shuffled awkwardly and did a bit of diversion from the fact that they didn't get any improvement going to the currently massively hyped brand of turbo from a turbo that was a bit of a frankenstein that had been well superceded in it's own range before the Turbosmart unit he put on there even came out. I suspect the EFR would outperform most Xonas for what a lot of less-insane RB owners would go for, in the 400-600kw range but the Xonas are looking hard to beat up to maybe in the mid 700kw range at this stage- basically where EFRs don't really reach, and before the Precision turbos take over.  What the Xonas do well in the "EFR range" is be easier to package etc, and work very well if a divided housing doesn't suit your application.

      Tomei gasket

      Are you sure the gasket is blown? What are the issues? Thermocure is the only flush I've seen do anything with rust, very impressed with that, Prestone, rust will be by the pool having a cigarette.

      And since the flush you have a blown head gasket? Have you lifted the head off yet?

      Hr34 fuel pump not turning on

      By GTSBoy · Posted

      The answer is to get a hold of the wiring diagram, work out what voltage is supposed to be where, when, and then work out why it is not there, then. I can't speak to the HR34 stuff, because I have never paid any attention to the NAs. There is a possibility that the turbo diagram will help, but it could also be different - depending on whether there is an FPCM on the NAs.
