      one tensioner on the timing belt is more than enough....

          yes there is only one but i'm against incorporating additional idlers, tensioners into the Vee belt system for the additional cost, points of failure and maintenance.

          it would make more sense on an M30 which needs the extra space

            You threw me on the 'timing belt'. You could run without the tensioner and idler and just use the manual adjusters and would be 100% stock BMW non maintenance parts. it allows to run a newer damper and one that's tuned (if there is any real difference) for the 84mm crank that I am running. I also have a ATI damper for my S54 that I am seeing what I can do for a hub.

            Or a supercharger setup 8^)

            (ignore the alternator holding up the SC, that was just to hold it while checking the SC > plenum > throttles alignment)

            Sorry for derailing your thread I though it was relevant to your post, I will make a new thread

                I'm not sweating it Keith, it's relevant. What did you do for the CPS?

                Right on dvallis.
