Frederic's radiator cooled intercooler.

[ECMnut at aol.com]

Some good examples of factory liquid/air intercoolers are
1.) Syclone Typhoon
2. Lotus Espirit Turbo
3. Toy MR2 turbo 
They have totally separate cooling systems, with a chiller
intercooler and pump, all tied together with heater hose.
The Syclone folks use a shurflow RV fresh water pump 
to replace the wimpy bosch unit..  It moves twice as much 
water and corrodes less.
