exhaust & PFC, what should I expect from my GTR?

[Simmo]

If I get a full exhaust (3inch or greater) including turbo dumps, and install power fc, maybe 15 pounds of boost, what kind of performance should i expect? Roughly what HP would i achieve? standard turbos aren't much good for much more boost afaik, is this correct? I have a K&N airbox insert, is this sufficient?

Is there anything else I should be doing? oil air separator maybe?

The car is mostly only driven on the weekends, and will attend the odd track day.

Cheers

the limit of the stock FMIC is about 400hp @engine

which is about the limit of the injectors, clutch and such as well.

expect time to be mid to lower 12's pending on how hard you want to launch

Simmo, by the end of this week, i will have PFC, 1.1 bar, exhaust (on there atm), cam gears and filters and i have been told to expect 230kw @ all 4... so yeah, in excess of 400HP and mid 12's would be easy to accomplish with that power...

if your drive shafts remain intact you mean?

:shake:

[PranK]

yea, well i have already proved that stock power can snap driveshafts...

[JAGR33]

What? You snapped a driveshaft??? Geez what were you doin??

I've got full exhaust, filters, adj. cam gears, 13psi (0.85bar??), which produced 215 kws at the rears. With stock clutch I managed a 12.3 @ 107mph (Calder Park), so with Power FC and a bit more boost, 230 kws would be achieved very easily..... and maybe dip into an 11 sec qtr.....

Thanks guys, Prank your using standard turbos? Have you got your car back yet?

mmmm nengun has pfc's cheap atm, tempting!

Whats the best option, use a avcr or the pfc boost control kit?

thanks guys

Simmo - PFC, 1.1 Bar, exhaust and filters = 209kw (280HP) @ all 4!!

JAGR33 - hit 2nd err... rather hard...

209kw with 1.1 bar is very low,weve done a few lately,easy 250kw with cam gears

[PranK]

i dont have cam gears tho...

u need them dude,cheapest horsepower money can buy

[Ethan_R32]

Ill second that.

vspecv got my R32 tuned with exhaust, 1 bar boost, filter and adjustable cam gears.

I got 240rwkw.

[PranK]

ethan, Rear wheel kw? or 4 wheel? theres a big difference...

cam gears will be next.

[hungry6]

and on the cam gears what are ur setting for a standard motor?

[Ethan_R32]

Prank, rear wheel. Theres not THAT much difference though.

[Guest RedLineGTR]

cams good upgrade...any specific brand..quality etc

[PranK]

Ethan, i reckon i could clear 250 kw at the rears easy.. you lose a fair bit through th 4WD..

depends whos dyno u use,ive had my car done where i get all my dynoing done in 2wd and had readings on other dynos in 4wd and basically the same.

i guess the difference is the guy who does mine basically does just gtrs and his dyno reads virtually exactly the same as the the 4wd dynos in melb.

same dyno as ethans was done,his car made 240 rwkw and i reckon would read the same on a 4wd dyno.
