Paul,
            With the motor mounted as high as possible in my glastar
sportsman, I find I have to mount the alternator on the side which
presents two problems. 1 the drive belt to the alternator now almost
rubs on the ignition sensor. 2 the belt is only driving on about a 1/4
of the main drive pulley which will allow slippage unless very tight.
So the alternative is to mount an idler pulley at 2 o'clock to the main
pulley which cures both problems.  Has anyone done this already? If so a
brief description will help, or better still a photograph!

Neil.


Yes I am well aware of that problem.

The best thing to do is do away with the CAS and trigger directly
off the e-shaft. That would allow mounting the alternator higher.
Both the 3rd gen RX7 and the RX8 are done that way.

Second best is an idler pulley if your EFI system cannot handle a
e-shaft trigger. Lots of idlers are used
on various engines. I think the 3rd gen RX7 and RX8 engines had them.
