Which intercooler to pick for a R34 GT-T

Awesome, ARC make really good coolers

$$?? Power increase?? Responsiveness??

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.

And have a look where your wastegate exits!

You can run 12.5 psi for more power I reckon. The guy who does my car is very conservative and he is happy with that. I trust him completely.

Yeah I spoke about more boost but they said the the turbo starts to drop off at the top end as you can see in the power curve. I'll be down on Saturday so I'll see what they say.

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.

Damn Adzmax, nice ARC intercooler!

Good choice, with $100 difference I would go the ARC too.

Good luck with the rest of the mods and the turbo choice.

Cheers. Will keep you guys posted.

[Abo Bob]

I don't think it's your turbo letting you down up top. I have a very nice split dump and it makes all the difference up there.

[adznight]

What type are you using? Have any pics? Where did you get it from and how much?

[adznight]

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 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.
