Cooling an issue with an SR powered 240?
Cooling an issue with an SR powered 240?
Using an S13/14 with an SR swap as a track car, does cooling become an issue if you hav a FMIC on the car? Does the FMIC steal all the air from the radiator?

If this is a "track car", you'd already have had an upgraded radiator (koyo, etc), and this wouldnt really be an issue =)

On a race track the fan does little but get in the way.PGBrian wrote:people manage to run it pretty hot.my guess is because they are stupid.
here is my opinion: DONT GET RID OF THE STOCK FAN.
Drifting is another story because airflow is not direct.
The problems SRs have are as follows:
1. Coolant flow in the head isn't the most ideal. Few FWD guys have been trying to come up with new ideas on keeping the coolant temps more stable throughout the head.
2. The water pump cavitates above 6k with the stock pulley. You will need to underdrive the stock pump.
3. Airflow to the radiator is slowed and heated by the FMIC core.
4. Incorrect fan shroud / fan choice. The twin 12" fans are popular but reduce the ability of the radiator to flow air at speed greatly. The fans were designed by FAL for FWD applications with little room. I highly suggest a single 15" fan over the twin 12".
Basically you need to add adequate ducting to force as much air as possible through the radiator. This means preventing air between the intercooler and radiator from being lost out the sides (top, bottom, side to side), taking in fresh air where possible, and expelling heat (vents).
$50 at Home Depot will do a good job at dropping track coolant temps a solid 5 or more degrees.
Not all cores are created the same as well, Koyo's aren't the best track cores because they have a habit of slowing the airflow too much which reduces the ability of the radiator to function. They are cheap and work fine for short events though.
