Since I had them handy, I figure I’d take few pics.

From left to right, Greddy, Ruf and 935/937 manual boost controller.





I found the Greddy one while looking for a 935/937 unit years ago and it was just too cheap to pass. I never used this one as when I was ready to mount it in the car; I already acquired the Ruf one. Seems to be well build and you actually need to push down on the knob to engage it to set the boost, so no tools required and secure.

One again, found the Ruf one on my quest to find a 935/937 unit, price was also good. I used this one for a while in my car. A bit annoying to set because you need (at least I wanted) to lock it with a nut using a wrench, it makes for secure setting but not easy to set on the fly.

Last winter, I found the 935/937 unit by luck and was able to get a good deal. First drive with this one today. You can set the desire knob resistance using the hex nut on the side. So once set, no tools are required to set the boost on the fly. It was very easy and quick to set my boost level.

Very cool! I assume you have the vent line plumbed into the upper chamber of the wastegate?

Let me know if you decide to sell the Greddy unit.
