Hi Paul & Group,

I'm going to use the stock Renesis alternator on
my Bush Caddy project, but I can't find a supplier
for a larger pulley.Does anyone know of a supplier,
or have any information on what other pulley might
work?I have found sites that sell the eccentric
shaft under speed pulleys but I don't want to
change that pulley just the alternator.

Thanks,
Bob

In the over all scheme of things the speed
of the alternator should be down on the list.
Have you some info that suggest the alt.
will fail if not slowed down?

Bob,
I used a 4" alternator pulley from Canton Racing.

Mark is using a 20B which has a lower redline than the
RX8 engine.

Mark, how is the p-port sealing coming?

On the subject of pulleys; for redundancy I was hoping to double belt the
water pump and alternator. I have a dual v-belt alternator pulley but I'm
having trouble finding compatible dual belt water pump and e shaft pulleys.
I'd be just as happy with a serpentine belt as a v-belt if only I could find
compatible matching pulleys.

You have a 20B right Jay?
13B stuff should fit. Check with Mazdatrix or Racing Beat.

Yes Paul I have a 20B (A991)
Madatrix does have a dual v-belt main pulley that, assuming it fits, would
leave me only needing a dual v-belt water pump pulley. So far that's the one
that proving to be the most difficult to locate.

It can always be made. I have a shop here in Santa Paula that
might make one on an NC lathe for a couple of hundred.
More than one would bring down the cost.
Does anybody else want one?
