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???

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 ?

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?

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

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:

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

    • So, if the headlights' cutoff behaviour (angles, heights, etc) are not as per 6.2.6.1.1 without automatic levelling, then you have to have to have automatic** levelling. Also, if the headlight does not have the required markings, then neither automatic nor manual adjusters are going to be acceptable. That's because the base headlight itself does not meet the minimum requirement (which is the marking). ** with the option of manual levelling, if the headlight otherwise meets the same requirements as for the automatic case AND can be set to the "base" alignment at the headlight itself. So that's an additional requirement for the manual case. So, provided that the marking is on the headlight and there is a local manual adjustment back to "base" on the headlight, then yes, you could argue that they are code compliant. But if you are missing any single one of these things, then they are not. And unlike certain other standards that I work with, there does not seem to be scope to prepare a "fitness for purpose" report. Well, I guess there actually is. You might engage an automotive engineer to write a report stating that the lights meet the performance requirements of the standard even if they are missing, for example, the markings.  
    • Vertical orientation   6.2.6.1.1. The initial downward inclination of the cut off of the dipped-beam to be set in the unladen vehicle state with one person in the driver's seat shall be specified within an accuracy of 0.1 per cent by the manufacturer and indicated in a clearly legible and indelible manner on each vehicle close to either headlamp or the manufacturer's plate by the symbol shown in Annex 7.   The value of this indicated downward inclination shall be defined in accordance with paragraph 6.2.6.1.2.   6.2.6.1.2. Depending on the mounting height in metres (h) of the lower edge of the apparent surface in the direction of the reference axis of the dipped beam headlamp, measured on the unladen vehicles, the vertical inclination of the cut off of the dipped- beam shall, under all the static conditions of Annex 5, remain between the following limits and the initial aiming shall have the following values:   h < 0.8   Limits: between 0.5 per cent and 2.5 per cent   Initial aiming: between 1.0 per cent and 1.5 per cent   0.8 < h < 1.0   Limits: between 0.5 per cent and 2.5 per cent   Initial aiming: between 1.0 per cent and 1.5 per cent   Or, at the discretion of the manufacturer,   Limits: between 1.0 per cent and 3.0 per cent   Initial aiming: between 1.5 per cent and 2.0 per cent   The application for the vehicle type approval shall, in this case, contain information as to which of the two alternatives is to be used.   h > 1.0   Limits: between 1.0 per cent and 3.0 per cent   Initial aiming: between 1.5 per cent and 2.0 per cent   The above limits and the initial aiming values are summarized in the diagram below.   For category N3G (off-road) vehicles where the headlamps exceed a height of 1,200 mm, the limits for the vertical inclination of the cut-off shall be between: -1.5 per cent and -3.5 per cent.   The initial aim shall be set between: -2 per cent and -2.5 per cent.
