Serpentine belt tensioners
Hi gents,
Have been reworking my supercharger mount and have found a slight problem...
Due to the space and canted over engine I really don't have many options on a tensioner setup. I was looking at maybe doing a manual tensioner
however the usual suspects on Google are coming up with conflicting information (I know what are the chances of that).
Some are saying that the belt contact area is more important than the tension put on the belt (180° of contact is the goal). I know that a automatic
tensioner will be better for when the belt starts to stretch or heats up, but on the other hand its not going to have the service span of a usual tin
top. I'm thinking maybe 1/8th of a turn on the adjuster as needed might create a little sweet spot and save me some headache.
Any suggestions?

I think I'd suck it and see how it went. However it's worth pointing out that auto tensioners help with variations from pulley lack of
concentricity, and so help with bearing loading. But that may be negligible if your setup is pretty good.

Thats what I have to work with ATM. Just the SC and tensioner on one belt. No real span to work with

Can you not have a bracket running from the right mounting point, over the top of the SC pulley, to another mounting point (SC flange or whatever else
is around there)?
With a bracket above the pulley, you could perhaps use something like:
Self-adjusting
tensioner
I have no idea if that one pushes the right way, but it is just a suggestion of type.

When i ran a supercharger, i used a fixed adjustable tensioner (Range Rover P38 air con tensioner pulley) which has an off set 8mm mounting bolt hole.
If your pushing boost boost pressure a bit and belt stretch becomes a problem then try using Gates Racing Blue belts....they really do make a big
difference.
