Message : FMIC's are intended to be mounted up front and air still goes through it. Air is also pushed under the car and from the stock intercooler holes. Why don't all the other cars with front mounts overheat? PrimeSpeed sold a FMIC to a customer that lives in CA and he has a stock cooling system and everything is ok. He has never overheated even with the AC on. I will try to get his name for you. Zroc lives in New Orleans and hasn't had any problems either. Does Project Z have to have it so you can mount it? If you are really scared, add a bigger radiator and a cooler thermostat.


: : those days, meaning over 85°, not counting the humidity you can not add a factor to it. If you block the only source of air flow or limit it you are playing with fire.
: : FMIC looks good but there are better alternatives to lower intake air temp or to gain couple of H/P like bigger and better ventilated SMIC, water spray, air to water, ice box.

Sure air goes through a FMIC but it gets heated quite a bit by the intake air charge, then it gets heated more by the oil cooler, then finaly the air gets to the radiator.

A lot of air goes over the car as well instead of through the air inlet because the thick IC core is a large restriction in the nose of the car. Air is not pushed from under the car because that is a low pressure zone and there is a belly pan. The belly pan is there so the radiator gets more air accross it.

I don't think any of the FMIC cars ever gets road raced where you are at WOT for more than just a few seconds. I am just about sure that it would be almost imposible to keep a car with a FMIC cool under those sorts of condition. It is pretty hard to keep them cool even without the IC blocking the air. Road racing or legal top speed events are way harder on a cooling system than just playing on the street, even playing hard.

The Daltech Escort World Challange Z had a hard time staying cool with a FMIC.

The car already has a Koyo radiator water injection and air guides to keep things cool.

Keeping cool is a secret to relaiblity for a powerful motor driven hard, If you can keep an engine from detonating, keep it cool and keep it lubricated you have gone a long way to make a motor bulletproof.

Z's when driven on the circuit overheat easily. This one can be driven up to 17 psi on a 100 degree day and not get hot.
