[KRiMiNaL]

Got my car dynod today and made 225rwkw at 16psi boost. What do you guys think, im cut seeing sum1 else on the forums pull 240rwkw at 13psi.

Modifications:

GCG 450hp hi flow

Bosh fuel pump

700cc Injectors

Haltec e6x

3 inch exhaust

Dump Pipe

FMIC

Pod Filter

Im spewing coz i had Vortex 98 in my car for the tune and my car was running like shit before i took it in. It is sumtimes pinging is this bad???

[bigcarl]

if it makes you feel anybetter im running sae turbo as you and ive got 240rwkws at 20psi. 224 rwkws at 17psi.

[3R1K]

What car? rb25det? rb20det?

Probably it's tuning, and different dyno could make different result.

Ahh, I heard Vortex 98 is not as good as Optimax or BP Ultimate, try to get retune with BP Ultimate.

[KRiMiNaL]

yeee im going back to the mechanic. My car is a r33 gtst rb25det

[Roy]

Easy fix, go to same dyno as tge guy who made 240rwkws:)

30km drive to pick up 15rwks:)

[KRiMiNaL]

haha, yee my mechanic told me if i got my car dynoed on croydon autosports dyno id have an extra 40rwkw.

[cameron]

2 problem's,

Fuel - Run BP ultimate not vortex crap...

&

Tuning - The best results that i've seen for car's with similar mods are running PFC's and inless you have a tuner that specialises in Haltec then you'r not going to get the full potential out of it.

r33 rb25. i will be selling my gcg st1 450hp turbo soon anyway, i just took delivery of my gt30, which will be going on once i get my supporting systems up to par with torbo.

Hi

Basically i have the same as you, only running a pfc instead .... and the tuner REALLY knows his way around the pfc ...

not a bad result tho ... how does it drive ?

[KRiMiNaL]

it drives good. I had 171kw before the dyno. Yee the mechanic specialises in in haltech computers he was happy with the result. I rekon with the better fuel i could of got better.

Oh yeee wats this about haveing to change the coils for more power???? the mechanic said its not good to boost it more until i change this?

[BHDave]

The stock coils aren't the greatest on an rb25. Seems to be limited to the 25 though, not the 20 or 26 which is a bit strange.

You'll find the car will develop a miss around the point of peak torque over time at higher power if your coils are getting a little old. I'm considering a set of splitfires atm, or retro fitting my rb20 coils and ignitor as an interim measure

[KRiMiNaL]

Ah okay i see. Mechanic told me ill be able to boost it a bit more if i get the coils, but said why do i want more power, and id be risking my motor.

[Col-GTSX]

Split fire coils

Blue in colour...

Produce almost twice the spark, due to they cap design....

They are sweet, but their not cheap brand new.... Try and buy a second hand set...

[KRiMiNaL]

u know how much on average they would cost?

[Sheriff Wan]

I got mine for $650 Brand new.

Usually get them for around $900 tho.

I got a set and they make a huge differance with NGK plugs

[Sydneykid]

I can't work this coil paranoia out, I have no problems at 265 rwkw with standard RB25 coils. Maybe it's because I use NGK copper plugs with 0.8mm gap. I have no problems with RB26 coils at 400+ rwkw either, but I use NGK copper plugs at 0.7mm gap. I have no problems with RB20 coils at 225 rwkw, but I use NGK copper plugs at 0.8 mm gap.

I see a trend there:cheers:

[Col-GTSX]

I agree....

Remember you need 3 things to get combustion in a petrol motor...

1. Fuel

2. Air

3. Ignition.....

If you want more power you need to increase the amount of the above to comply...

IE> A V8 has a higher capicity, more fuel and more air with 8 spark plug more ignigition. This equates to power power. A skyline has a turbo and very large injectors for its class. This means more fuel and air but no more ignighton.

You have done the steps to increase air and fuel... Now its time to increase ignightion...

Make sence????

Cheers Col

[KRiMiNaL]

ah okay thanks

[Col-GTSX]

Check out my avatar....

More fuel more air and a fu$kin big ignightion.... LOL

[KRiMiNaL]

haha yee wats it do down the 1/4 mile lol
