whos running a gcg stage 1 high flow turbo?

[Guest Robo's]

Yes i know about peak power not being everything, but i dont think the standard turbo is that peaky anyway, still has alot of midrange oomphh

[benm]

some people aren't just after the peak power output, but rather a quick spooling turbo for the streets with a fatter power band. its really upto the individual

I agree although would you be happy with a 20rwkw (peak) increase (over the standard r33 turbo) after spending $2,500 on an aftermarket turbo?

Edit: ...and running 17psi vs 12psi.

I think i'd be "over" 20rwkw after about 6mths and it would be a waste of $2,500 to me (personally).

I wonder what the average power is tho with that hi-flow.

[Gizmo73]

I would be happy with that - if the torque curve increased over the whole band (or in particular lower/middle), reduced lag and not forgetting the stock look & integration with current internals...

im looking forward to getting my turbo highflowed. i would be very happy with 290rwhp

For the RB30 I'm looking at a HKS3037ProS from Greenline. From memory they wanted 3100 or 3200 delivered to my door. Tax on turbo's is 3%.

[sweetr33]

thats nice joel matey but this is a thread about highflow gcg turbochargers not hks3037.

Yer was a bit of track..

Big carl: I ran a 12.90 with a 2.2 60' with the standard turbo @15psi. FMIC, twin plate, power FC, octane booster, 044 pump,zorst and filter. =)

[benm]

damn i'd be extremely happy with that

[bigcarl]

great result boostd!!! got to happy with that. how many rwkws were you pulling with stock turbo at 15psi? what tyre / size rim combination?

[bigcarl]

what was youre terminal speed boostd?

[Guest Robo's]

It must be running some big terminal speed as Boostd had a 2.2 compared to my 1.9 , and a 12.9 compared to my 13.3, that means he's picked up 0.7 through the run..Interesting, sure its not a hi-flow??

[benm]

According to my website (http://skylines.pnc.com.au)

2.20 60ft, 111.49mph and 12.900sec

Cheers Benm,

Thanks for the kind words guys

Robo: I was on the same mental track as you. Pulled the turbo off to reviel a stock unit. Just goes to show what they can do. I found strangly enough installing a new fuel pump made the most difference power(044) .....may be the key. It was last dynoed @ 218rwkw@ 15psi before the run. I did however run octane booster and dial in an extra 2 degrees advance for the night. My 2.2 was due to severe axle tramp. I have since installed solid bushes and am now running 18" 255 Nitto Extreme ZR Tyres.

Bigcarl: I was running 17" 255 @ 18psi Bridgestone Regano's (jap)

[Guest Robo's]

Why would the fuel pump make a difference if the motor is getting adequate supply??

15psi, hmmm nice, got to get my FMIC, then im going to whack in some more boost. If i can get 107mph+, a 12 is on the cards.

[BOOSTD]

Robo: On the Dyno the fuel supply was fine , however I found on on road testing if I kept my foot into it through the first three gears it was start running out of fuel. On the dyno the car is only ramped in fourth and so the issue wasn't apparent. 4th and 5th had a noticable difference. Have you noticed if you just sit in say third then dump it it feels faster than getting to third after thrashing 1st and 2nd.... (keeping in mind constant intercooler temps)

[bigcarl]

boostd where did you buy youre nittos from and are they as good as the nitto drag radials?

[benm]

I spoke to the guys from GCG today at Drag Combat (WSID) and it was $1,900 for either a 450hp or 500hp (same price) + $400 for something else (they dont have any "ready built") so you have to drop ur turbo off and it takes them 2 days to hiflow it.

[sweetr33]

the prices in the catalogue have gone up i think. I think 500hp is 2400 ish and 450hp is 2200ish

[BOOSTD]

bigcarl: the Nittos I'm using are suitable for street only because of their low profile and don't offer much improvement on take offs. Vastly improved in every other aspect of driving over any tyres I have owned, even in the wet.
