[Roadsters] Large Diameter Water Pump Pulley

[Andy Cost]

I got a pulley off a Chevy 350 from the junk yard.  It worked fine except
the center hole was not big enough to fit on the roadster shaft.  It was
easy to drill out.

Hi All,

Does anyone know where I can purchase a Large Diameter Water Pump Pulley.
Preferably not for a Kings Randsom

I need to slow down the water pump to try and get my engine cooler on a
Solex
Equipped U20 engine on my Race Car.
I am already using a 4 core radiator and ducting to direct the air straight
into the radiator. I need to pull the water temp back 20 degrees c or so.
and
this is one step.

I know one is made for the SR20, but is there anything around for the U20 ?

I installed one that I think came from the Z family that was slightly
larger,
but I would like to try and extra step to something like an 8" diameter as
the
engine mainly runs 4000 to 7500 for circuit racing , up to 60 mile events.

Oh, it is a highly developed race only engine professionally built by a race
engine specialist.

Regards,

Howard, Datsun 2000 Solex 3 of them: one race one road(nearly) and one
wreck.
