Hi I'm not exactly sure where to post this but looking for some advice.

I went to a road course today and after about 12 or so laps of the 3 mile course (Toronto motorsport park) I noticed my power steering fluid was boiling in the top up container. With the hood open and the car just running to cool the turbos a bit the power steering fluid was bubbling. Even after i shut the car off it was still bubbleing for a few miniutes.

I havd the APS twin turbo kit and the power steering top up container is somewhat close to the pipe that goes from the turbo to the intercooler.
I can take a picture tomorrow if needed.

Any way I was quite concerned about this. Has anyone else experienced this or advice to share?


thx

 

You probably need a better power steering cooler.

 

+1, the nismo ps cooler might not even be enought for your aps twin setup. dunno

 

Thanks for the feedback guys.

How much bigger is the Nismo one than the stock? there does not seam to be any space to put a bigger one in.

Has anyone else installed the nismo power steering kit with an APS TT system and where did you put it?

 

Don't waste your money on any PS cooler "kits". All you need is this:

Double the size of stock, mounts in the stock location and costs $30. We have 4 cars in Vegas using them, one of which sees track and autocross use.

 

Nice find i8acobra - thanks for sharing!

 

Nice find indeed. Alot of people pass up stoes like this. Always getting ripped by some high price product, (like Stillen) when there are other solutions that are just as great. With a reasonable price.

 

i8acobra,

Thanks so much for the info. I will be ordering one. At only 30 bucks it might cost me more to get it shipped.

Cheers.

 

That actually "looks" just like the nismo ps cooler--same double size and same mounting location, but this find is definetly cheaper! Good find

 

So retarded question:

What, per say; is the diffrence visualy when you have boiling and when you have cavitation from the return back pressure in the resivoir?

On startup the PS fluid when my wheel is turned cavitates or rather you can see the fluid returning and it looks a little like the fluid moving arround. But no bubbles. The obvious answer is to return the wheel to a neutral position and check. But visualy, doe the boiling look more like simmering water. I've realy never seen PS boil.

EDIT: After doing some research on diffrent PS fluid products, their MSDS's show an average operating temp range of -40F to 175F. The boiling points I've found have ranged from 297F for the average grade and 395F for the heavy duty stuff. That being said, at what point does the plastics get brittle or deform?

 

You're welcome.

Although I don't have a problem spending money on my car, I'd much rather come up with my own cheaper solution to a problem rather than buying someone's overpriced off-the-shelf "kit" (see also, my homemade catch-can DIY).

 

Of course, you can always switch to a higher-temp PS fluid like Redline has.

 

I'm running that Summit cooler. I even bought one of my local guys that cooler . We'll see how it hold up at the next autocross and track event.

 

Nice find, i just ordered one! Saved 70 off the BS nismo/stillen/whatever

 

^ Summit Coolers FTW!

 

thanks alot, I'll be buying tonight

 

Thankyou Istan , so far its holding up great. I have 3 autocrosses and 1 trackday on it. No more burned fluid and it even mounts in the stock location. Just use the zips thru it into the stock bolt holes in the bracket. I even used my stock lines!!!!

 

gonna bump this from the super zombie dead, the link isn't working, is the part from summit a actual cooler or just a bigger reservoir?

 

It's a cooler,http://www.summitracing.com/parts/DER-13200/





I run this one now, it takes rock damage so much better. Some fab work required. http://www.summitracing.com/parts/BMM-70265/

 

I use one of the standard Hayden cores (12x5 I think). It's on the flimsy side, but we don't have to worry about debris in the autocross world like the track guys. I'd run something like the one Terra mentioned above if you are prone to rocks/debris (aka track days).
