Ok, so bottom line, ive got a problem with my s13 overheating, but its only when i drift (which is 90% of the time because its a track car only). It takes about 3 laps on an average day for the car to overheat, and around 1 if im running a bumper. I have the e-fans running full time because it doesnt seem like they do s***.


I have...
-koyorad aluminum radiator -Flex-o-lite dual electric fans (has a shrowed with a rubber seal that
runs around the circumference of the radiator...very nice)
-stock thermostat (never replaced)
-huge fmic (which i think blocks the airflow to the radiator)

but heres the weird part...
I have an aftermarket aurometer temp gauge which is installed in the upper radiator hose. when my sr starts to overheat, the gauge goes all the way up to 230*F, but the oem gauge stay right in the middle all the time. The oem gauge will read when its cold, and seems to work, but once the car worms up, the gauge stays pinned to the center (half way between hot and cold)
