Re: im trying to decide where to mount my new ic heat exchanger
Firstly, I wouldn't expect too many people to respond in the 2-hour time frame you permitted... However...
I'm assuming that you're using a water-air heat exchanger. With the size you mentioned, I don't think that putting it in the location you suggested will affect the coolant temperature at all. However, I don't see it as beneficial to performance. If you're going to throw something between the grill and the radiator, you'd be better off going with a larger air-to-air IC, as the water-to-air system only works well in colder climates, or as a single-use system in a drag-race application. If you're in CA, I'd definitely go A2A.
