post up your best dyno graph...

[WHITE R32]

i just thought i would start a thread for people to throw up their dyno sheet and a list of major mods so people can compare and enquire what make a good improvement and what doesnt and to see how laggy certain turbos actually do make the ol rb engines....

i have :

lt12 plug in microtech ecu

gt28440hp bb turbo (t25 flange)

600x300x76 modified hybrid cooler

malipassi reg

480cc injectors

bosch 909 pump

3 inch exhaust with custom dump pipe and no cat

adjustable cam gears

profec b spec 1 boost controller

im especially keen to see guys with rb20 engines and turbos like 2530,2540 etc

my graph can be seen here.... http://www.skylinesaustralia.com/forums/at...achmentid=21307

low boost (8 psi) hi boost (18 psi) cheers Jon

[MidnightGTR]

305hp.. nice

I raced you ages ago out at willowbank when I had my maroon 33 gtst, this was when you had a td06 and mines ecu I think, guess things have changed

Stock RB20 Motor, or do you have internal work?

My R33 is still pretty stock but i have dyno figures for it.

it has-

- a front mount intercooler kit by Hybrid.

- a custom made double dump pipe by Drift King.

- a turbosmart boost controller switchable hi/low boost.

- 3 inch exhaust.

it makes max power at 6400rpm at 9 p.s.i.

[Bass Junky]

GTS-t V-spec.

That is the fattest power curve ive ever seen!

At what revs does boost build up?

[Abo Bob]

Here's mine.

http://www.skylinesaustralia.com/forums/at...achmentid=21289

I have a CES split dump/front pipe, 3" cat, fairly quiet Fujitsubo exhaust, Nismo Panel filter, AVC-R set at 0.8 bar boost and a modified stock ECU.

On full boost by 4k all the way through to 8.5k:D

WhatsADSM, It's an RB25, and has forged internals:D

[krzysiu]

Yeah i got 333HP (249.1Kw). Only problem is that i still havent gotten my damn printout from the dynoday that happened a month ago :| Got a pic of the screen though.

[Merli]

600.1awkw

[R31Nismoid]

come on merli... we are all waiting to see the graph

[Clint32]

gtst-vspec or steve sst does your GT30 have a 0.82 or 1.06 rear, cheers clint

[GTS-t VSPEC]

Clint, 0.63 housing

[33apx]

heavily modified (engine just been refresh when the turbo and cam shaft fitted)

Apexi RX6 high-mount turbo

Apexi exhaust manifold

Apexi external wasgate

Apexi cam shaft

Apexi valve spring

Apexi fuel pump

Apexi injector

metal head gaskit

ARC front mount intercooler

Full trust exhaust system

Blitz dual sbc boost control

z32 air flow meter

Just Dyno the car at Dyno source and it made 392hp at rear wheels in 1.3bar(pump fuel)

should make 430hp at rear wheel in 1.4bar with race fuel

on the dyno graph still show car run very rich at 392hp at rear wheel in 1.3bar.

[GTStR32]

This is my current set up, im pushing my injectors a little though, need bigger injectors

lt12 plug in microtech ecu

gt2535 turbo

600x300x76 hybrid cooler

bosch motorsports fuel pump

3 inch exhaust with custom dump pipe and no cat

Bleed valve boost controller

215rwkw on 18psi

Dyno paper i will post as soon as i can get it scanned

[Duncan]

I saw merli's 600.1 rwkw graph...but he claims to have "lost" the pic now.

here is mine from the SAU Dyno Day today

Apparently it was running too rich, so we should be able to get the extra .3 rwkw with some tuning

[DoughBoy]

For a laugh, T51R Kai, standard RB25, 9psi.

p.s. I honestly thought I would have alot more power down low.hahahah.

[B-Man]

I'd love to know Paul's secret to 450HP. I'm nearly there - with similar turbo (larger rear housing). Dude did you have an exhaust on your car when you got the 450 ?

This is 23 PSI - ( get no difference in power from 21 PSI upwards - tried 25 PSI today and 2 rwkw less - same dyno)

[DoughBoy]

GT30 is pretty ambiguous as to the size of the turbo, the GT30 family is huge. Then again, it could have a '30 rear, and a larger family compressor. Such mystery!

ps. 450 hp is 335kw, different dyno could accomodate such variation.

Edit: You can't compare the A/R directly between Garrett vs HKS - different designs where the HKS units have a smaller radius ®, so the area (A) could be the same on a larger HKS vs smaller Garrett.

Edit2: You would probably find that you can drop the size of your turbine housing B-Man and not lose horsepower.
