New Mods that i hope help me get to 200rwkw

Dump and front Pipe Twin set up off BOS

Hi flow Catco cat

PLUMB BACK BLOW OFF VALVE caust stock one isn't working right Flutters on 7psi

loud ( NOT sure on what brand anyone know any good ones for Plumb backs

custom 3" pipe intake from turbo to Pod without AFM due to link computer

last of all thinking Cam Gears but will they heap on stock cams

Those mods with a good tune should push you to that figure, or very close to it.

But if you looked in the Quick Ref guide at the top of this forum you would have seen the following threads

Ex. Cam Gear: http://www.skylinesaustralia.com/forums/sh...41&page=1&pp=25

Dump Pipe: http://www.skylinesaustralia.com/forums/sh...ead.php?t=10567

btw, 140kw is what you would expect for a near stock Skyline. That must have been a really really bad tune..

I know 140rwkw is low but i beat one of my mates with a gts-t with a full exhaust so i am guessing maybe the dyno was just out been just beaten by a 180sx and onces by a gts-t with least mods then mine he was a better driver

I am Hoping its just the Tune Mrt will work out whats holding my Power back

Gears are gears... I'd take OS Giken. Stay away from HKS.

I don't think the new HKS Duralumin cam gears are as bad as the old ones?

Tony,

Cmon you should know better Those are the "Revision 1" HKS gears. The "Rev. 2" gears -- which use duralumin -- don't appear to have the same problems.

Edit: I'd still look at getting the Tomei gears as part of the camshaft + camgear packages they do.

I don't trust aluminium in these sorts of conditions. It's up to you.

Well the Tomei's are made out of exactly the same stuff.... No idea on the OS G's though.

Cam gears will make some difference, but not 60+ kw. (AFAIK, all they do is move the power band, they don't necessarily make more power).

I suspect it's the tune. I'm running a RB25DET on a Wolf 3D. It has VVT, and is otherwise stock. It was tuned at 10psi on 95 octane, and pushes 180 kW out through 4 wheels (R32 GTS4). Granted it does also have a "hi-flo" cat and a dump pipe, but still runs the factory air box and filter.

endof the day cam gears will only do one thing.....

go OS giken .. 325 from greenline (posted to melbourne) they only sell them in pairs.

tomei ones are getting pricey

[Bass Junky]

If you want to try adjusting the inlet gear whilst keeping the use of your VVT, PM me.

I've got a little invention that may just help you out.

[shif_tea]

Hey whats the deal, is there something freaky about my car cause i got it dynoed with minor mods (see sig) and even at 7psi it was pulling 169rwkw, and was 186rwkw @ 10psi.

Was dynoed at unigroup, i would have thought scottmans would have been more powerful...

Must be UBER dodgy tune

[Bass Junky]

Show charts so we can figure it out.

[scottman]

i have no idea why its only 140rwkw i am hoping to try and fix it hoping its just the tune

other things it cound be is Fuel Pump or injectors or something MRT will find out hoping to fix it

still i own lots of shit with 140rwkw

I thought it was shited so i went and raced my mates Gts-t r33 with a Full Exhaust and BOV and i beat him so i have no Idea maybe it was the dyno

Yo bass.Have you made some for r33 now.Or is this a trick that you have up your sleve.

[Bass Junky]

R33 and R34

[Col-GTSX]

I have the newer HKS gear and its fine....

Didnt gain anything at all... Just got a few more km's per tank and smoothed out the top end.... No jerky action inbetween 6-7000k....

AND more importantlly i got FLAMES>>>>> LOL

[Fastrotor]

Scottman, what dyno was it on ? The dynologs read alot lower than the DynoDynamics ones (most common).

I just had car on dyno yesterday to retune, and all i could get was 145 rwkw's (Dynolog)

(was tuning it myself)

Now bear in mind this is S1 R33 GTST, std turbo

3" turbo back, and i just put a 4" magic cat in (which does work well by the way , 4 gas analyser confirmed)

I have a plug in LINK. No AFM (3" SS Pipe to pod)

Carbon cleaned it too.

R34 GTT cooler

And just fixxed the coil probs with a mates 32 GTR coils borrowed till the splitfires arrive... also new BKR6EIX iridiums (.8mm std gap). After last tune the coils shat themselves , siliconed them to get by, but power was flat...

Also fitted a MV auto shift kit.

Its been a busy 2 weeks !

Heading out to drags again tonight to see how it goes...

Two weeks ago with it feeling flat it ran a 14.6 @ 95.3 mph So i hope i can get a 13 tonight ... time will tell.

I think you should go out to the strip and just see what mph your getting ......that will be a better indication of how well the cars going.... as your dyno may read low as well.
