Engine cooling mods for the Gencoupe

This is what I have thus far for cooling system & keeping temps down in engine bay:


-Silicon radiator hoses (MODE)
-Aftermarket radiator (Mishimito)
-Aftermarket radiator cap (Mishimito)
-160 degree Thermostat (GrimmSpeed) - not using currently
-Throttle body coolant bypass

-Turbo Blanket (ProjectPTP)
-Heat wrap tape for EM & DP (ProjectPTP)
-SS exhaust manifold heat shield (MAP)
-CAI w/surround block off from engine heat (CP-e)
-P&P w/ceramic coating turbo, intake & exhaust manifold (MAP)
-Intake Manifold Thermal Barrier Gasket (Exceladyne)
-SS 2x thick exhaust gaskets (head>exhaust manifold, manifold to turbo & turbo to downpipe) (Grimmspeed)
-Race FMIC & wrinkle coated piping (Buschur)

My mods so far for cooling:



-GrimmSpeed P&P and Thermal coated Intake Manifold

-GrimmSpeed P&P and Thermal coated Throttle Body

-GrimmSpeed P&P and Thermal coated Stock Turbo

-Grimmspeed Phenolic spacer

-GrimmSpeed 160 deg. Thermostat

-elite auto engineering heat shields

-ark grill (have seen and avg of 2-5 degrees cooler intake temps with this grill)

-venair radiator hoses

-1.3 kg/cm2 rad cap

I have the phenolic IM spacer. I took the drivers side fog bezel and ventilated it. Don't want to do the passenger side as it would allow too much rain water to hit the air filter. I have put a baffle between the air filter and engine compartment. This stops the pull of air from inside the engine compartment on that side of the air filter. I need to seal off the areas between the IC-condenser-radiator and open the bumper cover up in front of the APG IC.

I've ordered the Forge silicone radiator hoses. Where as the hoses don't help reduce heat directly they can take the increased pressure of a 19 lb radiator cap. The Forge upper hose also is one piece. This eliminates the metal to metal contact of the OEM radiator coupler pipe under the IM. I don't have this yet but also plan to see if I can wrap the upper hose in some sort of radiant barrier.

An oil cooler is a must and what I have is marginal it appears. But still kept the oil temp a lot lower that without it. I've also installed an aux cooler for the PS. Got rid of the aluminum loop pipe that is OEM. Need to bypass the heated water that goes through the PS pump mount. I think this adds a lot of heat to the PS system.

Yesterday I tried to install some leds to indicate what fan speed is running, hi or low. With the BR tune the low speed fan is on all the time unless the high speed fan comes on. The fan stays on regardless of vehicle speed. It appears the only time the high speed fan is on is due to hi pressure in the AC system. I could not get the hi speed fan to come on at any temp below 225F. I guess a manual switch for track days may be in order to force the hi speed fan on.
