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.

      Infiniti Q60 Navigation Update

      Yeah I understand you have to pay for an updated map or subscription service or something. But I can't even find a current map for Australia. My map is dated 2017, but didn't this car version still sell in Australia until 2021?   Also, just as an aside, the navigation system warns you of traffic incidences ahead.....why would they include that on a map they knew is not receiving live information. I am forever going to be warned of an incident that probably existed for 30 minutes 8 years ago.

      Run it in open loop for now, and drop the frequency down. This lowers the resolution and requires more duty cycle to do anything, however good to troubleshoot.

      According to Josh, one of our local Americans, it seems the USA still can't get turbo systems quite right at a lot of places, so possible that they're not running great at all, but they've just not complained as NFI about getting it right...
