Hello all, I am wondering if there are any of you who have had issues with your power steering systems on Cayman S that have seen track time. I have a friend who experienced this recently, and I am currently wrapping the power steering line on the engine in thermal heat wrap and adding an external front mount power steering cooler. I will have pictures as the project progresses for those interested. I believe the failure point on this car to be between the main reservoir and the pump itself. The red pressure fitting on the back of the main reservoir was also on its way out, but had not yet failed. I will keep this updated as I make progress. All work in engine bay is completed, except for bleeding and filling, and the front mount cooler is mocked into place but not yet hard mounted. It will be fed with a few holes in the center grill. Lines into the cooler are -10 AN fittings, and use a 3/8 mineral/hydraulic oil resistant line to tie into factory system's return side.
Edited to add some pics from the engine bay:

With A/C compressor out


View of line where it snaps into Reservoir


Where line makes the curve to drop to undercarriage. Grommet was re-installed, where gold U-shape is.




View from above with line reinserted into reservoir.


Similar as above pic, different angle


Pump and compressor reinstalled.


There is a Cayman buried in there somewhere:

 

A well known problem on Boxster/Cayman of any year running comp tires. High steering forces often boil the PS fluid, the return fitting at the PS pump fails and all your fluid is left on the track in turn 9. Your fixes are proven to work. Do inspect/replace the return fitting as it is probably heat damaged.

 

Know where to get the red fitting in the reservoir for the return line? not sure if you can get it separate through porsche parts

 

An underdrive pulley helps (but doesn't entirely solve the problem). Adds approx 6whp as well. I happen to have one for sale. Sorry for the shamelessly self-serving post.

 

Anyway we can get the photos back up?

 

Will try to over the next week or so, al my photos were removed from my old hosting site, slowly getting them transferred to a new one, but am a little strapped for time until earyl Feb.

 

Thank you it is appreciated!

 

I have a new BBI pulley of the latest Gen (for Cayman/Boxster) for sale if interested.
