Specific Circuit Intercooler Requirements

[myfgturbz]

avo make a cooler, ejz-747 has a avo cooler on his fg, and had 450rwkw in it and its as small if not smaller (in height) than factory cooler) worth looking into

Water sprays onto the outer core of your Intercooler will help out heaps.

dunno if allowed on the track?

space the bonnet off the hinges .. I did it to a jeep once .. temps went down 11 degrees

Probably a stupid suggestion, but would there be any way a top mounted intercooler would help?

Would need something like the vent/scoop in the territory I'd imagine, but it seems that radiator airflow is more important than intercooler flow?

edit: either that or some sort of seal/shroud between the intercooler and the radiator - forcing all the air that comes through the intercooler to also go through the radiator?

not having a dig at you but why is it you seem to be the only one having trouble with this? Most are complaining about heat soak in the cooler, or brakes failing at the track not so much car overheating. I thought these things did pretty well in the heat...

Drain the coolant and run a water with three scoops of clothes washing powder. We use it on site to clean out radiators and cooling systems. The caustic in the washing powder works a treat in breaking down scum and oil from the cooling system. Then flush it all out after cruising for a couple of hours. Don't rev if hard coz the water pump will froff the water and cavitate the water pump.

Also ensure you are not running to much antifreeze. Use the minimum amount of antifreeze as you can as straight water will always cool better then a coolant mixture.

Also check ya head gasket with a coolant tester and ensure your thermo fans are sucking into the engine and not blowing out of the engine bay.

Are you using stock thermos? Or aftermarket fans? Are you getting 12.7-13v at the fan motors? ( check this by back probing the wires in the plug as you want load on the circut from the motors while you test this.

You can also check to make sure all your coolers are horizontal to the ground. Any angle ether side of horizontal with cause more restriction to air flow as the air will have to change direction as it flows through the coolers.

It was a humid day close to 30deg when this occurred.

Frustrating because can't chase any lap times due to overheating.

The brakes used to be the first to go but they have been well sorted now. I've been doing this a while. Synthetic fluid with 318deg boiling point.

Even with the Race Spec only Project Mu H16-013 pads (for Brembo) they are holding up well now.

Proper brake ducting including enclosed fibreglass shrouds on inner front hubs to removed foglight on drivers side. (Straight from the control V8 brute ute series. 100mm dia high temp orange brake ducting.) I've cracked 2 sets of dba5000's straight through and have gone back to 4000's because they are cheaper.

Ideally would use an Alcon or AP 6 pot caliper with proper air vane rotors but cant justify the cost. Current set up is outlasting engine temps anyway.

The passenger side foglight is blocked with an engine oil cooler so the passenger side brake duct starts from under the intercooler. This may be part of the problem with air flowing under the intercooler and not directly through the radiator.

Will be doing a full pressure test soon. Head gasket may be a possible cause.

Will still be ducting the radiator a bit more effectively closing off the top and bottom and also bonnet vents just behind the radiator with a similar design to the RS Focus.

Will be relocating the power steering cooler and possibly cutting the top off the stepped PWR intercooler.

Make sure you do the pressure test at engine operating temperature. And I think it will be more accurate to test the coolant for carbon and residue chemicals from combustion.

[nelsonian101]

Had a quick check and no obvious head gasket leakages but have always had problems with the thermostat housing, but never this bad.

Could this be causing the problem?

Have replaced the gasket a few times now, but should I replace the top housing/cover too?

(Needs to come off anyway when the 82deg goes in anyway)

I wouldn't think it would matter. You would just loose coolant and you would top it up as required. Don't forget to change your thermo fan settings as you'll want them to come on earlier with the thermostat as well. Or just pull the relays and bridge the battery wire to the output wire and have em run flat out all day. You could also try a higher pressure radiator/expansion tank cap. A higher pressure cap will keep the coolant more dense and will pull more heat out of your engine and transfer it to the cooler/radiator.
