thanks sky...the result was only 2kw short of its best ever pump fuel figure. Considering how hard we used to push the pump fuel tunes its really impressive to almost top the figure given the limits set.

the plugs were everyones favorite BCPR7ES's....we ran something colder with different style electrode...even they were not the optimum plug for the application.

1100+hp turbo vs a pair of 460hp turbos, its easy to see why its making around the same power but easier paul. it should wake up a hell of a lot more with some decent boost behind it

make sure u grab a plot of afr & timing too please paul

i remember when Mark was tuning the Autronic ECU with the GT-RS's the difference between 22 and 25psi was mad...one made good power, the other made the car almost jump off the dyno. They really woke up and it was only 3 measly psi difference.

AFR power and torque only.

all i was interested in was the amount of timing inaccuracy there is up in the rev range, i'm assuming ur still using the factory cas only for timing? could be something worth looking into, even if u dont want to give out those details

we use the Nissan CAS for pump fuel...have another set-up for race fuel when we 'wick it up'.

why would you change the cas? the vi-pec uses a digital signal

couple of reasons...crank twist and belt deflection. Mark says its the way to go on a WOT high rpm drag car...im just doing as im told by the master. Its no fluke he's the 3rd fastest in the world, his car is ultra consistent and reliable. The custom set-up does not use a tooth style trigger wheel mounted on the nose of the crank...its nice and stealthy. :P Im sure Shane knows the set-up im refering to.

ah yes so u do, i couldnt remember if it was you or mark that used that 'backwards' setup

Paul will you always be running the bell mouth on the turbo with no filter?

Nice result.

Will a power band of 3500 rpm be enough to get you down the quarter faster than before with out a super dooper gear box?

No i will not always run the Japanese air filter...getting a pipe made up this week to suit 2 large K&N items.

Yeah its a nice result but its not a real indication of what it will do...the dyno printout is pretty useless as the line disappears off the page ill get Wanye to rescale it tomorrow. The AFR's read by the dyno on the 465 run were closer to 11 than 11.4...yikes! But this was may have been due to the plug change as it was spot on 11.4's the night before.

I do have a super dooper gearbox...its a PPG fully optioned straight cut dogbox. The car shouldn't see much less than 7000rpm down the strip if im on my game.

Took it for a run on my 'test track' today...its nuts already!

I was thinking something sequential. Is yours still a H pattern?

What ever you use it still takes nothing away from the car being nuts. Good work.

Yes its a H pattern. The box is so slick to change and not a hassle at all on the street once you work out the way it likes to be shifted. On the upshift you would be hard pressed to even know it was a dogbox and on the downshift a simple increase of about 500rpm double shuffling allows it to select the lower gear without the clunk.

Paul, are there 2 different trims of the GTR-s kit? Or did you bolt on 2 SR20 spec ones? When I bought mine they were advertised as a 700ps kit for Rb26.

Thanks

Hey paul, do you know what marks fastest time was with the hks t51r on street tyres?

Cheers, mat.

Haha, im keen to see his GTRS graph at 22psi vs the 25psi one

No doubt the single wouldnt be as much fun for what i use the GTR for compared to Pauls use, but then he's not worried about lag :thumbsup:

    • GTSboy, thank you again. i’ve been reading all the other SAU RB25 vacuum line threads and you have the utmost patience for people asking “where do my vacuum lines go”. it’s appreciated. i did also enlist a few other RB guys local to me.  i would like to run 5 to 4. turbo pressure side to wastegate actuator. i would like to run 3 to 1. power steering air valve line to intercooler outlet. (this is how it was previously). i was told 2 is the bleed port for the boost solenoid - which i’m not running - so should be capped.   anyone see any problems with that?    
    • So yes. All of them. Something like 98% of all fuel in the USA has 10% ethanol: https://afdc.energy.gov/fuels/ethanol-fuel-basics It's labelled as like, AKI, 87, 91, 93 with an E10 or E5 or E15 label on the pump. At a certain point, it's not just "E10" instead of 91. It is 91, 95, 98, and all of them have 10% Ethanol in them. You can also get E85 and E30 which is why you do see some people rolling around with E30 tunes in them.
    • Thanks for the response. This is an 04 EP3 Type R. JDM spec. Fairly certain they're just basic BC racing coils. I do plan to keep as the ride quality on stock I've been told is pretty meh given Sydney roads. If I were to go down that avenue, does NSW require them to be a certain spec (close to original) etc?
    • Should have asked what is the car?
    • I've had two super conflicting experiences with blue slips. My 30 year old E39 waltzed through with no issues but my brother in law was knocked back on 12 y/o 3 series due to wiper blades and some cracking in a control arm bush.  What kind of coil overs? Do you want to keep them after?  If it was me I'd get some dirt cheap shocks and springs from eBay or scumtree. Not ideal but will get you over the line and might even be less than $1k.
