Power steering cooler option.
 

Anyone see these? This company has a ton of different sizes to pick from. Here is just a random one.

It's tube and fin but I'm sure you can find one much bigger than the OEM one to cool things down. All of them are in the $30 range. Much cheaper than other options.

Better than stock, yes; anywhere near enough for AutoX, hell no. I run the PS cooler kit from Z1 and I still boil my fluid by the end of my heat. For HPDE it might be enough but I can't say for sure.

I'd guess this and yours are the same size but different styles. You running better fluid too? They have kits including a fan but say oil cooler. I wonder what makes a tranny, ps and oil cooler from them different.

Redline synthetic fluid. The key to heat rejection is surface area. This tube and fin just doesn't give the fluid enough surface area to give up it's heat. Fluid rejects its heat into the tube which then gives up its heat to the fins and then the fins into the air.

The stacked plate coolers offer greater surface area for the fluid to give up it heat.

Only difference between tranny, ps, and oil coolers is what the manufacturer decides to call them. A heat exchanger is a heat exchanger regardless of what you want to call it.

Right. If you're still boiling than whats it matter? What side effects do you have?

With the cooler I have the the boiling isn't as bad as it was with the stock cooler. Generally it stops boiling before my next run whereas the stock cooler the fluid just kept boiling throughout my heat. Long term, if I don't change out the fluid frequently I'll probably have a PS pump fail.

fwiw I wasn't trying to rain on your parade. The cooler you found is a great alternative to the stock one. Just wanted to make sure the autox guys didn't buy one only to have buyer's remorse.

Well ill go look at it. Maybe buy 2 for only $66! Hook it up that way.

I got the Z1 power steering cooler too. You can see it on the left side of the picture.

What's the bar? Something nismo?
