Uses engine coolant to cool air charge into manifold.

what about air to air ? a little more plumbing and bother, but good none the less. i bought a chinese 450x300x65 cooler for AU$165 you may be able to get stepvan/dodge ones over there. i haven't fitted it to the car yet, so i don't know how good it is.

After cooler or intercooler or both

my .02 the point of the after cooler is to heat up the air more.. However, in doing so dont you remove O2 and make it less efficient? I just bought a step van 4bt and was thinking of doing installing the after cooler but I just can't seem to think why go this route instead of an Intercooler of even both? pros cons I am not sure I know for a fact though that all the reall high HP diesel engine Like cat E ratings etc have both 3412 TATI pumping 1500+hp at 2300 rpms. True these engine last as long as a chocolate candy infront of kids at halloween but they still get hp out of them... Can anyone clarrifiy best route/action to take...:confused:

well, technically if there is only one turbo, they are all aftercoolers. it seems to me air/air might be better. ambient air temp is cooler than engine coolant. their purpose is to cool the air to lower intake temps.
