power steering cooler.....

[5UBZRO]

Now on my project i am in the process of fitting up a set of gfb underdriven pulleys....

i am also piecing everything else back together and was wondering how much of an effect does the small loop of p/s pipe that used to run between my old radiator and a/c radiator has on cooling the ATF. if i could i would like to run the return hose straight from the steering rack back to the reservior, rather than running it back through the front as the i/c would now be in the way. would having an underdriven p/s pump cause it to run not as hot?, thus not requiring the need for the cooler. If i still need to cool it i will just run a loop of bundy next to my oil cooler which is in the original wrx top mount i/c position.

it probably would help the oil stay cooler to stop the seals in the rack and the pump from overheating and ev entually leaking...

Could always run a small oil cooler relocated somewhere if you are worried about overheating, there are a few people Ive heard of just removing the piping but I think if you are gonna drive hard in the twisty stuff its better to have a cooler of some sort in there.

Your car is a race car right?

If so, you will need a cooler - best to fit an aftermarket one, the factory "loop" thing is very average - use a small auto trans cooler. The fluid gets pretty hot on the track (especially at Taupo) and it is not uncommon for it to squrit out the reservoir cap.

I am using an auto trans cooler mounted in the drivers side guard - seems to do the trick.

yeah thats the one. that might be the go then. i was thinking of running a similar loop system around the front of the intercooler but it got me thinking about stones etc....
