Midmount Intercooler Setup

[mongoose]

Hi all,

Does anyone here have any experience with mounting the intercooler inside the engine bay? In particular S15ers from Australia? There is an Australian kit made by Predator Motorsports that places the IC between the A/C and the radiator.

This setup allows for really short piping, I'm just wondering whether heat soaking is going to be a problem with the radiator being so close to the intercooler. I read of a similar "RS2-Spec" kit by HKS, but this was limited edition and all sold out by now...

Surely the benefit from the shorter pipes would be offset by the restricted flow? Unless you removed the air con...

My initial questions - which may be completely inappropriate but I don't care

1. How does the radiator compare in terms of cooling efficiency. Is it going to be up to the job of providing cooling?

2. is it a good idea to have the intercooler so close to the radiator? The combined thickness of the radiator and intercooler may impact airflow and cooling? Would there be heat transfer from radiator to the intercooler thus reducing intercooler efficiency?

From what i have read on this setup its mean to improve cooling no end......... think it was maybe SXOC i read it

Looks good, bit worried about the size of the rad though, could it not be the same size as the intercooler?

I had a friend's opinion that if A/C, intercooler and radiator would be stacked up one after another, then no matter what the order (even if intercooler is out in front), the flow through each of them will be governed by the most restrictive item... ??

Which is the most restictive??

a friend of mine recently installed V mount cooler
he said that the engine reponse increased

The shorter the pipes, the less the lag. Doesn't mean it cools better...

V mount is good for race car



daily driven hmm dont do it... weaken the chassis

You could always fit a water spray kit, you could even get it to spray front of cooler and back of radiator, that would surely offset any heat soak.

 

[S15R]

probably the the engine will be wet aswell

 

[Nicely]

But then there's the added weight of the water tank...

 

[S15R]

haha i was thinking of using the jap spec washer bottle and connect the water line for rear windscreen for IC spray

 

[Topper]

How about using the rear washer pipe to spray the IC with, S15R you suggested this before, i think its a good idea, but how would the anti-freeze effect the IC?? Would make it a nice colour of blue/green :thumbs:

 

[Nicely]

Try that here and you'd probably dissolve the cooler with screen wash and anti-freeze....

 

[S15R]

lol we dont use anti-freeze here

You don't have -7C charge temps either...

I think this depends on core thickness.. I mean the a/c's fins don't appear to be that open but it's really quite a thin core at the same time, and say a really thick 100 mm intercooler core will also definitely be restrictive unless you are always driving max out

about the radiator: the size seems to be a compromise in this sort of setup, even if you had intercooler inlet and outlet to the sides, the endtanks would also be in the way of flow..
