[Roadsters] Water Pump Pulley

[Steve Jacobson]

Howard,
We use a SB Chevy unit on the 1600.  You can get a alum one from local parts
store or Summit part# SUM-G3963 ~$31.  Big hole is OK, but will need to drill
new holes for the pump flange.  Can then also use std water pump spacer shims
if needed.  There is one for the short neck and one for the long neck SB
pumps, this I think os for the short necks.  Overall depth about 2.5-3", 6 or
6.5 inch diam.  USes ~3/8" belt.

Just talked to a local 2L roadster racer this weekend, he runs fine with a C&R
radiator, stock pulley, says he never uses the fan. C&R wanted him to run
stock pulley??? Some ducting in the grill to keep the air in.

Subject: [Roadsters] Large Diameter Water Pump Pulley

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....
