GTR Intercooler flow ???

[S14Drift!]

Is the Skyline GTR Intercooler flow enough for 500HP application ?

I need something that flow ~ 700 CFM, but I couldn't find spec for that stock Interccoler...

[Lepperfish]

yeah from whats been said on the forums they can flow uptp 600hp no worries...

The stock intercooler is massive, there should be no problem until crazy hp.

I know that it's big...but bigger doesn't always mean better...

I have seen very big intercooler, done with cheap core and ugly square end tank...

This is why I want to make sure of all that before I buy it, I can get one used for 500$ Can, which is very close to 500$ Aus... it seem a good price, no?

S14,

I upgraded my intercooler when I put 2530's on my GTR. With the standard cooler I got 280hp at all 4 wheels at 1.1 bar. With the new HKS cooler (600 x 300 x 103) I got 320hp at all 4 on slightly higher boost (1.15). The dyno showed around 40hp gain right across the range from around 4000rpm right to redline. I know guys who are getting 400hp at the rears with stock FMIC's so you can get good numbers, but I wonder what they would get with a bigger cooler?????

Something to think about anyway...

Just remember not all GTR intercoolers are the same.Some models flow alot better than others.

That's exactly why I asked about the flow... cause even if it can do it...it doesn't mean that it's doing efficiently.

How big is the diameter of the piping on the HKS kit? and how big was the stock?

I guess that you have a bit more lag with the HKS, is it noticeable?

When approaching 400rwhp+ then I think the GTR cooler will provide sufficient pressure drop that a larger cooler will be preferable.

anybody know which out of the coolers , flow the best ( out of the standrd GTR ones) and what opinions might you guys have on the Greddy coolers ?

[GTS-t VSPEC]

I believe the R34 is the best for flow.

woo woo thats what i bought for mine.... wanted to make sure i made the right buy , what about after market ones which would be the top 5 ?
