I'm making a hybrid (so to speak) air/water ~ air/air intercooler out of my Action Fab stretch. What I''m planning to do is box in the upper "original" core while leaving the lower half core exposed to the atmoshpere.
This is a weekend cruiser which will see more street time than track time, so I wanna keep it partially air/air to help alleviate any problems with heat soak of the water/air part. My buddy Neal Whyte ran his car this way for several years & I'm taking it a step further by adding a resevoir (stainless, sits where the stock coolant overflow bottle is) and pump to circulate the water/ice/alky mix & help increase the cooling capacity of the unit.
