So my Koyo radiator bit it. I came back from the track and I noticed she's leaking. I need to take it out of the car and see what's going on but I think the crappy fan mounting I had going finally did it in.
The Koyo is way too wide, I can barely fit any fans in there let alone a shroud. The only fan I can fit is a small slimline on the trans side with some shit solution for mounting. Where the header is there is absolutely no room at all.

Finding radiator dimensions is challenging at best so I'm stuck now wondering what I should do. Should I buy another Koyo and attempt to find a better way to mount my fan? Should I just go stock and have plenty of room for fans? Or are there other options that offer more performance but are thinner than the Koyo? I am worried about the stock radiators ability to cool off my engine especially on a road course which makes me even more confused.

If anyone has expirence or width numbers with different radiators that they can share with me it would be much appreciated.
Thanks - John

It looks like you have room in the front, so you could always install a push-style fan and shroud on the front, and just make a vent for the hot radiator exhaust. I've seen rally racers run dual radiators as well, using a half-size in the front with a thermostat that opens up to a second rad when temps get high enough. Given your space requirements, that might be a solution. I'll see if I can dig up some pictures of the dual-rad setup I'm referring to. It was pretty ingenious.

How much room do you have? you can do a push and pull setup also if you have the room.
