Is a 100mm thick intercooler a waste of time?

[Shaun]

GDay,

Just thought id ask all you gurus if a 600x300x105mm intercooler is a waste of time on an R33 GTR engine with forged internals, GT35 700hp turbo and upgraded everything else. Ive currently got a Hybrid 600x300x76mm cooler and i suspect this wont be enough to cope with about 320 - 350rwkw.

Ive got the opportunity to buy one for about $400 new so im just seeing what you guys think. Also, GCG in Sydney offer the 100mm intercoolers for $900 core only. Is this a bit steep? Any ideas where to get one for less than GCG's price?

Thanks,

Shaun.

it all comes down to the fundamentals of the design etc of the core as to wether an intercooler will work or not.

in saying that , it is a common misconception that bigger is better.

more often than not a greater thickness of the core is required when the face (surface area of the core) is small.

i am of the opinion that hybrid coolers suck , though im sure many upon many guys have them on cars producing 350 at the treads, which is their choice i geuss.

remember that just because a cooler "flows" 500cfm , doesnt mean it will work , the way a cooler should. i mean a peice of down pipe from ur gutter flows 500cfm but does it cool air.

if i was you , and judging by ur car and engine combo i wouldnt skimp in any area of its build up , go and buy a cooler and or a kit from www.are.com.au , i am biased towards that company as i have known the owner for a good 13-14 odd years now, and have seen numerous back to back tests and logging etc of various coolers, and also have one on my vl

in other words , 400$ for a new cooler , no way , go spend that 400 on alcohol and waste ur money on something u will enjoy

when you pay 400 dollars for one, i spose it cant be that on most everyday street skylines

however, with your needs i might look at something better

yeh i bought a big as 2nd hand cooler of the nte,it was shit?it was 4 a vl turbo buy the way

not sure why you went the Hybrid choice over the stock GTR cooler as they are good for the power figures you are aiming for anyway. The thing to remember is how well it cools the air passing through, not so much how much it can flow. Not 100% sure on this one, but if you go too big it creates more lag. Someone correct me if i am wrong.

Thanks guys,

The GTR engine is going in a GTSt, so i didnt already have the GTR cooler. Ill give the cheapo a miss, its too much of a risk. Thanks for your advise.

yep good choice i have seen gtr's with reasonable gain from 250rwkw over the stock gtr cooler. a good 100mm cooler is the way to go not a cheapie. the jap branded ones are proven as well whihc cant hurt

I had an ARE bar and plate on my GTSt and was very impressed

Another recommendation for ARE!
