I suggest you do your clutch before you go, just ask Col-GTSX how badly it sucks.

Standard Clutch and 200rwkw = Fryed clutch and a 24 second pass at 50mph... :laugh:

Exedy Custom and 240rwkw = 12.4@111mph (street tyres)

Yeah i actually burnt my clutch during the burnout (2nd gear burnout). When i left the line the car went no where and the revs went through the roof. I ended up droping it into 2nd and crawling away and i go up to about 80kph i think as my top speed on that run... ;)

My traction and suspension was absolutely shit.

was getting rear end bumping on take off, to i ended up takin off a bit slow till i hit 5,000rpm and then hit 2nd gear and just took off.

1st one i didnt do my gear changes all to well

2nd one i did them alot better.

low mph were cause of bad traction (shit tyres & shit stock suspension).

BZZZT Wrong. With your setup you should have a great big whack of top end regardless of wheelspin off the line.

With a 2.6 60' my old 180 would still pull 111mph and smash into the 12's.

Stock suspension is doing you a favour over drift-spec coilovers so you can't blame that either.

I'd be looking at how you launch and when you change gear. Either that or you don't have the power you should - which is what your MPH tells us.

The tyres are shit. I'm actually due for new ones. Plus the tyres on the rear are absolutely shit anyway, shouldnt even be using them on the quarter mile or qld raceway.

With the suspension. If i allow wheel spin, the rear end is just jumpin up and down non-stop till i take my foot off the accelorator and then re-gain traction and then take off a bit smoother.

After talkin to dan. Pineapple bushes will help this but there could be other factors involved causing the rear end to jump up and down such as the diff or suspension.

The plan right now is - replace suspension with ISC coilovers (they are new on the market and little has been said, so i'd be happy to give these guys a go and see what happens).

Next, after that is a new turbo with external wastegate and high mount manifold.

With the mods i've done already, the car should be putting out around 250kws. I'm only getting 215kw's and when on the dyno, something is restricting us back which we dont know.

Last tune, we started off and got 296hp and after several times of playing around with the mapping on the powerfc, we kept loosing 1 or 2 hp even though we Matt Spry was properly tunning it giving it more in some areas of the injector maping, etc.

Guess one thing I should be finding out is if there is any leaks anywhere and start doing some testing on the engine (compression, etc). Alot I think needs to be done before I look at the turbo upgrade though.

So your saying that you had axel tramp? Its a bitch aint it? getting off the mark was my hardest part as the other cars were flogging me there even though I gained on them up the strip, I put it down to practice and setup and working out the right tecnique. 13.7 btw 3 times.

      98 R34GTT 4k engine stumble

      By JC71 · Posted

      forgot to mention that when it does this it does not kill the engine, but I have not kept the pedal down long enough to let it, as I see no reason to beat up on it as its got to be something simple, small and dumb causing this.  And as soon as I let off pedal, the engine returns to its normal super smooth operation and rpms re-stabilize quickly, once below 4k.

      98 R34GTT 4k engine stumble

      By JC71 · Posted

      neither stumble or cut really seem to be an appropriate term....hard to explain its like a rev limiter but at 4k, but it violently shakes engine and entire vehicle as the rpms will not rise over 4k, even with slow acceleration. as soon as it hits 4k, it sounds like entire spark is lost entirely. plugs were 1.1 which I used as such, but later put in new plugs gapped down to .8 changed back after issue arose when I replaced the coils, still does it with either plug gap...damn and it was all running so good.

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      Oh how times have changed! I actually lean it out relative to my water/methanol injector duty cycle. The methanol adds a lot of fueling and you can then lean it out even more due to reduced knock.

      Yeah my thoughts are the same, a well thought out WMI setup, would be slightly ahead of just straight E85 and you're also chemically intercooling the charged air, dropping it even further. This is why you need to add so much more fuel as soon as you spray. I remember someone taking me through their set up before (Dennis, has a R33, lives around Cabramatta - no idea if he's still around on this forum). He would target AFR 10:1 on 98, then as WMI ramped on, AFR would lean back up to 11:1. Amazingly, he did this all through his PowerFC, a relay to cut power to his EBC solenoid if there was not enough line pressure on his WMI kit. And of course, if there wasn't any boost made above gate pressure, you wouldn't be accessing the load cells with heaps of timing for WMI. One downside to that rudimentary setup, once the WMI came on, the EBC would unleash the dragon, and of course all the timing. Tyres would fry lol.
