Water pump pulley OD Easy one for someone.
What diameter is the stock LS water pump pulley?
Finding a reference motor in the UK is nearly impossible, and I have a new water pump that doesn't have a pulley fitted.
I can machine one myself, but need an approximate OD to make it easier...

Original question was looking for info for smaller diameter pump pulleys. My thermodynamics class way back when would disagree with notion that running water faster thru a heat exchanger would cause higher temps. We did a lot of testing with different cooling systems for our specific application and after a certain coolant velocity there was little effect, but flowing too slow significantly increased temps.
Too long a dwell time can significantly decreases efficiency as temp delta decrease early on it the radiator passage….whereas faster flow increases temp delta between coolant and air which increases cooling efficiency. So, I would err on side of increase flow speed.
So, anyone know of smaller pump pulley suppliers without having to CNC my own?
