what reg you running? how much boost? is it a safe tune? what duty cycle are the injectors operating at? pod filter? exhaust (cat-back)?  thanks.

From those figures I believe

- 12PSI

- Stock rock ECU

- Turbo back exhaust (bashed out cat? :D )

yer? correct me if I'm wrong

Oh dear.........let's do some numbers.........

Standard injectors are 370 cc's

92% = 340 cc's

340 cc's in a 6 cylinder = 340 bhp

340 bhp = 254 kw

less 60 kw for losses in an R33GTST = 194 rwkw

218 rwkw would =12% increase in fuel flow

12% increase in fuel flow = ~40% increase in fuel pressure

standard fuel pressure is 36-38 psi, so +40% = 53 psi (above boost)

53 psi plus 1 bar boost = ~68 psi

I sure as hell hope you are not running 68 psi through the standard fuel lines and clamps, that is asking for trouble.

:D cheers :D

PS; 1 bar on the standard turbo, tick.....tick......

just curious how this figure was derived.

pretty run of the mill mate, search around. Lots of info.

Drivetrain loss is lies between 25-30% from the motor the the rear wheels.

SK have used approx 25% in his calc of 60kw

Cheers

Oh. and yeah, turbo wont last @ 14psi, not thats it'll be doing much above 10/12 anyhow.

also, above 1 bar equals a nice amount of hot air being rammed into your engine.

I'd be keeping an eye on that knock sensor..

and and for your info, I am running 11psi, and got 210rwkw. Why so much more boost just to get a measly 8 rwkw, and risk blowing your motor \ clutch \ turbo ?

dont mean to take over this thread, but just a quick question.. i got my car on the dyno today to see how much i got from the new apexi cat-back.. its a series 1 r33 GTS-T AUTO with just an apexi power intake kit and an apexi cat-back echaust.. it made 155 RWKW, does any one know if thats any good considering its an auto and pretty much stock?.. what would that be KW @ flywheel instead @ the wheels?... and does any one know how much KW a stock standard auto R33 has?.. thanks for the help.

      The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.

      R33 GTR running -9 with no tune

      Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.

      I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋

      Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
