I'd gap them a little to promote flow through the cores (those standoffs on the rad would suffice), but I'd completely shroud them together so all air that enters the mouth flows through either the rad or IC then rad.

Does leaving that gap not create pressure at the rear of the IC? Or does the larger volume of air to the IC overcome that?

i dunno. air's going to flow through regardless; especially once shrouded. There may be a gap between the two, but that gap should be filled with insulation or shrouding.

I feel like if they are touching you first risk damaging the cores, then reduce the flow through the IC if it doesn't have any easy way to escape, and thirdly the heat radiation off the rad.

AHHH- ok I get it. The perimeter of the IC is sealed to the face of the rad.

I think I'm going to go down the water cooled route and be done with it. Couple of options for heat exchangers:
Barrel intercooler water to air cooler liquid to air intercooler 4" x 8" | eBay

I kind of like the idea of the barrel one as it keeps the air flowing through without change of direction but suspect the classic shaped one cools a bit better with what looks like a bigger core and capacity. I'm sure I could make either work as behind the radiator is the one place I have plenty of room to play with. Any ideas or thoughts on these styles?

thumbs down.

luke2152

Any particular reason for thumbs down or are you just winding me up

I know you suggested a smaller air/air one

Consensus around here is that water/air is fail for anything other than 1/4 mile at a time. Y u no like advice?

Braineack

unneeded complexity for a less efficient system. and you still need to mount a heat exchanger in front of the radiator...

complexity and weight.

bleh

I do like good advice (thanks all) hence the questioning. Does water/air really heatsoak that quick. I thought it would ideal for road use, and ok but less then ideal on the track. Depending of course on the size of the extra radiator.

I will keep my eyes peeled for a suitably sized reasonably priced air/air one that will fit. Not quite as easy to come by this side of the ditch in non standard sizes. Other thing is the mounting points on the radiator are designed for a fan - maybe not manly enough to support an bar and plate cooler. Quite a few other things to keep me busy on it in the meantime.

how much room do you have this way?

luke2152

[QUOTE=Braineack;1209690]how much room do you have this way?


At the bottom of radiator <1"
At the centre point about 5"
At the top about 10"

You still have to find a location for the second radiator. Heat flows charge to water through first one. Water gets pumped to second one the air flows through the second radiator. Do you have a good place for it in mind?

EDIT: wow, lots of posts that I missed from when I opened this thread till I made my post. Sorry for the redundancy.

luke2152

Well I was thinking directly attached to the radiator with them spaced apart as far as I can manage (not very far). Something about 2/3 the frontal area of the radiator but much thinner. I've never actually seen one but I assume they are similar/same as an oil cooler or perhaps a radiator from a sportbike? Otherwise an opening could be created at floor level or at knee height to the sheet metal either side of the engine

As long as you have a way to run the charge pipes (2" rather than, say 1" for the water lines) you are better off just putting in a FMIC. This is especially true if whichever one you choose is going mounted on the same place on the car.

Likely that is Brain's question about the space on the sides. You have plenty to route the charge pipes that way, rather than over the top, and use some form of FMIC with side entry.

luke2152

Ah I see I thought he meant clearance to the grill/front. In that case there is absolutely no clearance around the sides. There is more then 2" space between radiator and the nose on the top though but barely.

And he may have meant it as you thought.

All in all it looks like your original idea seems pretty good. Sizes match well enough for easy ducting, sealing between the FMIC and the radiator, as was discussed earlier.
