Good Electric fan(s)

ok so heres my issue my twin turbo iroc will stay at 165* while idling all day long with both fans running , the minute i start driving it it will reach about 215 which is to hot for my taste.

on all my turbo cars i like to keep the engine right around 180-185* while cruising at the dragstrip this will usually end up around 210* at the end of a pass

i believe my biggest issue right now is that i have a 4 inch thick inter cooler core mounted in the nose of the car restricting what airflow i would normally get threw the rad at speed.i also believe the factory fans don't pull enough air, unfortunately i don't know how much air they actually move.

ive tried everything from 160-180-195* thermostats , ive tried no thermostat, ive tried restrictions as well to try to slow down the water flow, the results are always the same at speed

can anyone suggest a aftermarket fan or fans that would be better then the stock 3rd generation dual fans ?

the regular fans generally pull enough for a standard engine and perhaps slight upgrades,

do you have a hood scoop or any type of cowl hood

no i dont, im actually changing out the iroc hood for a flat base/rs model hood to go with the whole sleeper theme

the only other thing i can think of is to try wraping the turbo headers/downpipes and see if it makes the car run any cooler , but i dont think wraping up the headers/downpipes are going to make enough of a difference

Yeah, I would be thinkin' that there just is not enough air available. Have you thought about re-positioning the aftercooler in the rear of the car, pulling air from under the car?

that would be a plumbing nightmare, im going to try sealing off the nose by building some ductwork form the opening in the nose of the car around the intercooler and radiator and see if it helps. this should force all the air to go threw the intercooler and radiator instead of around it

A third gen Camaro has to have the airdam in place under the front or you wonīt get air circulating into the rad while moving.

what we have done before is to remove or cut out the inner fenders and either put your intercoolers at that location with pull through fans or put fans them self at those locations.

got some ideas from the guys over on thirdgen.org. my intercooler is mounted 2 inches ahead of the radiator behind the front crash bar. its been suggested that i remove the front bumper cover and notch the crashbar to fit the intercooler infront of it. this will push the intercooler right into the opening of the front bumber cover and give 7-10 inches of space from the rear of the intercooler to the radiator.

i dont know if this will allow more air to flow threw it but it should deff allow to car to pick up more air undernieth to go threw the radiator, as right now there is only about 1.5-2 inches on the botom opening for air to get past the bottom of the intercooler

or i can try to push the bottom side of the intercooler twards the front of the car effectively mounting it on a 45* or so angle in the nose.
ill prolly try that first and see what happens

If you are running more boost from your system, you will noticed a lot more heat.

On my integra the smaller pulley caused incredible operating temperatures.

Iīve just made a new dual fan setup with a thinner fan shroud on a Jegīs aluminum radiator.
The fans are 12" Flex-a-lite Trimline Electric Fans 112which are the bigest side by side I could fit.
I did try an 18" fan but it failed miserably.
I thought about a 12" with two 9" but you just canīt package them onto the area of the shroud.
My setup does leave areas without through airflow so I split the shroud down the middle with a divider on the rad side to increase the fanīs "suck".
Shroud is 30mm deep.


This is my previous deep fan shroud setup, I went to thin because here I have no comfortable access to the front of the motor.It was a pig to make as well,
you have to get around the lower hose and steering box.
The idea was the fans could suck from all corners of the rad, the thin one does the job just as well.
