Anybody running Properfekt? I currently have a standard recirc on an R26 282bhp. Are they up to the job or do I need a piston type? Don't want a BOV or DV. Thanks Mike.
The replies have been overwhelming.. I have bought and fitted a Properfekt. Nice bit of kit. Came with 2 springs. The piston was stuck, where they had red greased it and put the piston in, just needed pushing back and forth couple times then it moved nicely. When fitting, top right bolt is easy, bottom just takes patience, but if you cut a grove into the face of the top left bolt, you can screw it in with a screwdriver, then nip up with a spanner. Took me about 15minutes to fit the new one. Sounds good too, makes a slight flutter sound. So far, would well recommend.
