Increasing the efficiency of a SMIC

[old guy]

What paint did you use.

Very interesting stuff on the intercooler. Nicely done!

I used Akzo Nobel color matched paint mixed ready to spray and Transtar Quick Gloss Acrylic Urethane catalyzed topcoat. The key is the topcoat. It flows really well and sets up fast which is critical when you are spraying outside without a spray booth.

The best setup is a water cooled IC, side mounted, with a remote radiator including a dedicated pull through cooling fan, located behind the lower grill, forward of the A/C evaporator/radiator using a cooling water circulating pump. The size of the remote IC cooling radiator is small enough to be mounted easily, without blocking the evaporator and radiator enough to effect engine cooling.
Since the IC on our cars functions mainly as a heat sink absorbing heat from the hot charge air from the turbo compressor, a water cooled IC has many times the heat absorption capacity compared to the mass of an air cooled IC. Water has the unique property of being able to absorb the most heat before the bulk temperature of the cooling water starts to increase. A water cooled IC with plenty of cooling capacity can be very efficient and compact size.
