Return Flow Intercooler Vs Regular Front Mount Intercooler Question

[yoshiii335]

Hello

I have a front mount return flow intercooler on my r32 GTS-T. It came with the car and I do not know the maker. It is not as big as a regular front mount intercooler.

What hp are return flow front mount intercoolers generally good for? My goal is 400 hp for my car.

It depends on the brand and design obviously, can you post a pic? Should be good for 300kw or so, if it doesn't make it to your goal, change it then?

Some of them do restrict flow, that causes a massive differences before and after the cooler. It depends on the amount of boost you wish to run also. For the best result always get proper front mount cooler with 600x300x100mm core.

Always 100 mm core seems excessive

I'm making 300wkw from the stock evo 7 cooler, and 350awkw through the Stagea auto on a cut down Jap core 600x220x76. Obviously you can get better results the larger you go, especially if the cooler pipes are large diameter, but there is a price to pay, and transient response will suffer. Peak KW is only part of the story.

If you plan to lean on the car hard, such as dyno and track work, go for the largest and thickest cooler you can fit without cutting bits of the car off. Otherwise you would be better off keeping what you have for the road most likely, best bang for buck I say...

So for 400hp if I am only driving mostly on the street, my intercooler should be fine?

[scotty nm35]

Should be, but like I said, it's hard to say without seeing a pic, even then we are only guessing.

Do you know how to post pictures on this forum?

Ok I think this should work.

or

2. Open e.g. a photobucket account (free) put it on there and then cut and paste the link

Does it have a brand name on it?

What brands do you find to be restrictive Stao?

Some of the JJR ones, and also Blitz. For this reason I've installed a blitz return flow on my current R34 and curious to see what it does. I've noticed some of the blitz coolers has very narrow tube, mine doesn't, but it has very tightly packed fins inside those tubes.

I've done a test based on 600x300x68mm and 600x300x100mm coolers. There are no differences in response, while the IT was 10 degrees less with the 100mm, that lead to 10kws gain top end. For a cooler setup that what I recommend.
