Interesting, allbeit probably rubbish charge cooler

There doesent look like enough turbulence in there to pull any heat from the charge.

Looks like the sort of thing that might just work in a short term application (eg with an ice water tank for the drags), but a separate radiator is merely adding an extra heat exchanger into the equation, compared to a normal air-to-air intercooler.

The losses from two heat exchangers are very likely to be worse than the losses from one heat exchanger. I would call that a less efficient system.

Actually charge coolers are more efficient than inter coolers, why do you think the IC cores are so big compared to a comparable charge cooler cores.

This is because water is better at cooling than air is (it has a higher latent heat). The only problem is that the pre-radiator before the chargecooler uses air as a heat transfer path.

So i suppose use a chargecooler with a big pre-rad and a decent pump
