Let us know, Kelly.
 
I have a Racing Beat underdrive (20%) = main pulley=20 and a Racing beat underdrive (20%) alternator pulley (I presume that = means the=20 alternator is 40% underdrive).  At idle my low voltage warning = light begins=20 to glow especially after starting the engine.  It slowly feeds the = battery=20 but really wants more rpm to get the voltage up to the 14 volt=20 range.
 
However, my water pump pulley is pure = stock and=20 with the 2.85 7000 rpm is certainly a possibility.

OK Guys,
    If there is anyone still planning on using = old=20 fashioned "V" belts and
a mechanical waterpump listen up.......After detailed analysis = (with a=20 ruler
and calipers) I have found out that the "Star Racing" large = diameter=20 water
pump pulley is 5 inches in diameter and is designed to be used = with=20 the
reduced diameter "Racing Beat" excentric shaft pulley used by = most=20 of
us with 13B rotary (86-91) vintage.......The "Star" pulley is = the=20 largest that
can be used with the "Racing Beat" pulley and probably should = be=20 considered
a must have item for those using the RD1C, 2.85 redrive and = planning=20 on
extended running at or above 6500 rpm.......IMHO......The use = of this=20 pulley will
keep the pump well away from its cavitation rpm and reduce = the=20 power needed
to pull it at high rpm.......The "Star" pulley has a 17mm = (.669in)=20 pilot which
fits the 86-88 13B waterpump.......If you have a 89-91 13B , = 13B or 20B=20 Cosmo
pump its pilot is 19mm (.748in) which can be bored out=20 easily......Before
everyone runs out and buys one of these let me order one and = verify=20 all
I have guessed about here........FWIW

I need a larger diameter waterpump = pulley (dual=20 V-belt) for a 13B rotary. From
your website it appears that your "Star" = engines have=20 what I need. What year
of pump are they designed to fit and how = may I=20 obtain one ?
 
Thank You,
