just had my car dyno!

450hp gcg turbo

550cc injectors

z32 afm

fmic

pfc

3" exh turbo back

greddy filter

nismo pump

nismo reg

hks evc 3

200rwkw at 10 psi

220rwkw at 1bar

the tuner thinks that it would get more power at 15 psi by looking at the 10 psi boost. we have tried to boost to 1.2bar but it dropped back to 15 psi. He reckoned that it was leaking pressure somewhere and possibly the stock BOV! any suggestions would be appreciated!! :rant:

It does sound like you need to fiddle with the cam gear.  I have 228rwkw at 12-13 psi, same turbo.  This is an auto though so that equates to a bit more.

Abo:

what degree did you set your exh timing? The thing is i got 200rwkw at 10psi but as i increase boost to 14psi i got 224rwkw but when increased another psi i got less power! Basically the graph power is like a straight line! note also i have turbo surge at 3500rpm as well! :whatsthat

3000: 85rwk

3500: 115rwkw

4000: 138rwkw

4500: 156rwkw

5000: 175rwkw

5500: 193rwkw

6000: 205rwkw

6500: 217rwkw

6700: 220rwkw

7000: 215rwkw

do you still use stock BOV?

Dodgy dyno sheet as the clutch was slipping as boost came on then grabbing on at higher revs... made for crazy power dips along the curve.

Stock injectors were close to max at this power. New injectors (when money permits) will allow 18-20psi which will bring this turbo more into its efficiency range as at the moment it still has a lot left in it.

Hi

Car: Impul R33r Sedan

Mods are as follows:

- HKS 2835 Pro Spec S with HKS Actuator

- Apexi PFC with Boost Controller

- Nismo 550cc Injectors

- Z32 Air Flow Meter

- R33 GTR Intercooler

- R33 GTR Fuel Pump

- NPC Nismo Style Pressure Plate and Ceramic Clutch

- 3' Dump and exhaust

Made 230.7rwkw at 17psi, could have got more, but didnt want to lean on the engine too much. Nice and safe.

i was pullin 200 kw on the stock turbo  

dyno is in the hks gt2530 thread

Thizzle,

I understand you got 250rwkw with a HKS GT-RS, PFC, 1 bar,FMIC.

What are your other mods? if you have any, such as:

injectors?

fuel pump?

FMIC size+brand?

Pod/Panel filter?

Exhaust(size & name)?

Top/Bottom-end....Stock internals?

This information would be most appreciated. Thank you.

Bill

late reply havent been on much lately...

man thats a long time ago i currently making 301.6 rwkw on the tiny gt-rs on 1.38 bar boost.. i got some hks cams and head gasket and a retune...ill scan dyno later..stock internals,ALL parts u asked about are HKS..cool turbo for street use in sydney..

Bought my Skyline two months ago and got it serviced and dyno'ed a few weeks back. It outputs 142.7kW at the rear wheels. Was very impressed with this output as it is only a stock car.

I plan to do some performance upgrades to it once i've saved up enough.

My first post on this site. :D Looking forward to posting many more.

R32 gtst 93 rb25

Apexi PFC

Tomei cams

Arais forged pistons

gtr rods

550cc injectors

Z32 airflow meter

FMIC

3.5inch Exuast

HKS 3037 proS

HKS ssq blow off valve

Yet to do the final dyno run but it is sure to make over 280rwkw on 1.2 bar

With a bit of 116octane she should make about 330rwkw on around 1.7 bar

- 10psi

made 170rwkw. with misfire on 11-12psi, stopped the run, coils earthing out

taped coils with nitto elec tape = no missfire, yet to dyno

PFC on the way, then what sort of grunt would it make with 12psi and FC? anyone?

Does taping the coil packs only help when they have obvious cracks in them?? I'm having trouble with my RB25, have searched alot and tryed a few different things but still got the misfire up high (4500 onwards)

Might aswell add mine too I suppose.

RB25

-Hybrid turbo

-fmic

-exhaust

-haltech

-custom plenum

-600HP fuel pump

-249RWkw @ 12.5 Psi

Dyno done over a year ago before buying the car, so it needs a tune badly. Got some injectors to go in and fix the misfire then might turn the boost up a bit more

      S1 rb25/s14 starting problem

      By Duncan · Posted

      Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      By 25zenki · Posted

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
