if yes, ill do a better stop plate under the correct angle, but it really limits the travel of the tensioner. how much is good? a little more or less or exactly corresponding the marking when installing its at 15C

No mate, once is enough. It's pretty easy to make, just cut it out of some 10mm aluminium plate on a band saw and drill and tap a hole. It don't need to be all fancy like I made it, but mine is going into a hotrod so it need to look nice.Tazio wrote: Any chance you made more than one of those plates? That looks like a good solution for adjusting out belt stretch on the fly.
