The cooler kit cost me $1500 delivered. Although it's a bit more expensive than the equivelent HKS item in my eyes after seeing the quality of the ARC cooler it was money VERY well spent. The ARC cooler is not as big as the HKS Type S in size but it's power rating is more than enough for me. I'd be max 250kw.

Speak to dAVE in the Vic section for more details on them.

Abo Bob - I know this may sound strange but after I put the cooler in I took it for a quick spin and it seemed to come onto boost with a lot more of a punch. I mean it wasn't boosting harder but just seemed to come on with more of a surge and there was a little bit more noise.

It's hard to tell what difference it made as I had the Power FC, FrontDump pipe and Bleed valve installed at once so it's now running 10psi after a dyno tune.

The power is pretty good and the delivery is awesome but I still want more. I don't really know how much more I can do without looking at a turbo upgrade though.

Have a look how restictive the stock dump pipe is! -

You can see round the flange how small the pipe joining into it is. Around 2" would be my guess compared to the 3" I have on now.

Put some more boost into it. I repeatively done back to back runs from 10-13psi and we were gaining 10-15 up high, but midrange was like 20rwkw more, thats were you feel it. Just tell ICE you want some more boost. If you want more power, this is a fix until you get used to it.

Had the car checked on the Dyno on the weekend, turns out was running far to lean at high boostRPM. Looks like my fuel pump had had it :cheers: I need a Bosch 975. Best price so far is $280. With it running a little richer is now making 190kw but boost curve drops at high end. Need to fit a HKS EVC to fix that. With a new controller should be around 200kw. Will post a dyno sheet.

      Wheel Sizes & Offsets For Skylines

      If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

      If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.

      MAJOR FUEL ISSUES 25det neo r32

      By MBS206 · Posted

      Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
