What size cooler for power steering?
I've removed the stock ps fluid cooler to get room for my larger oil coolers. What size cooler should I replace it with? It will have to cope with track conditions.

Well... I wouldn't call 4 coils of 3/8" aluminum line much of a cooler.
It's very much like the 911SC's that had a loop of -12 line as an oil cooler. It didn't do much, which is why it was never used again. Which is why everybody installs a real oil cooler.
And they really don't need to do much because there's simply not a lot of heat generated, nor is there any air even directed over them.
My new LSx 951 doesn't have one. And I'm running 300 Yokohama slicks on the front. There's zero PS fluid issues. And those are about as sticky and wide as you'll ever get on a 951... and I can promise you... the car is pushed hard.

I put dual oil coolers on my turbo a few years ago and used a 10 ROW-8AN cooler for power steering, mounted it in front of the radiator.

tufs, if you do decide to use a cooler i have a suggestion..
if you have salvage yards look for the 1980s/90s volvo 240/740 cars, they have a small setrab cooler with -6 or so fittings..its mounted in front of the radiator.
see this old post of mine for pictures.

Thanks guys.
I'm tempted to go with Tony's suggestion. After all I live in a cool climate and the widest tires I will use in the front is probably 245s if I ever get good enough to handle that much front bite.
Tony, have you ever measured the ps fluid temps? I'm tempted to stick an adapter on the line and see what the temps actually are.

I don't have a cooler and running 275s up front with no real problems, but then again I have electric power steering pump and it has a fairly large reservoir.

Thanks Tony. That settles it. I'll go with no cooler for now. I can always add one later if needed.

Power steering cooler delete???
I'm pretty sure the soft line between the power steering cooler and the reservoir is leaking on my '86 951. I'm not ready to shell out $180 for a new cooler/line assembly. I also will confess that at the moment, I'm a little too lazy to remove the cooler and attempt any sort of "proper" repair. So, that leads me to this thread. It sounds like I could simply bypass the cooler altogether. In this scenario, I would just run a line from the return line that comes from the rack, directly up to the reservoir. This sure seems a lot easier and cheaper than trying to deal with the cooler.
Am I missing anything here?
Thanks.

how about just cutting the crimped end of that hose off the cooler and then running a new piece of hose from the cooler to the reservoir, held by clamps (maybe fuel injection style clamps)?
not under any real pressure and it's clamped at the reservoir end anyways...
