Mat, those pulleys are what I thought I bought, but I find that
I have a 2 inch alt. pulley which will require the alt to get up
to approx 20,000 rpm AT 8000 Engine rpm. This is unnecessary and
takes a lot of HP on its own for no need or result. The load is
such that the fan belt will not drive it over 6000 RPM. I say
that as it could also be the water pump but I think not. First
step will be to drastically reduce the Alt speed to around 1:1
engine speed. Will be interesting. Thanks Neil.

From the rx8club group, they say the stock
generation rx8 water pump will start cavitation around
6000-6500rpm using stock pullies. This guy simulated the pumps
and got around 7000rpm.
