Need a Water Pump Pulley
I have decided to go after the overheating issue in my race car once and for all. Anybody know of a source for the larger diameter water pump pulleys that high RPM 13b's are running? I have the Racing Beat Main and Alt pulleys on the car, but at Mosport you can see the temps climbing as the rpm's go up. I want to control cavitation.
I would also look at used ones, if somebody has one in their possession that they don't need. Double shieve please.

Mazmart makes a replacement water pump that doesn't have the cavitation issue at high RPM... Also, its not ment to be underdriven.

If your turning over 8000 rpm buy the pulley kit from Mazdacomp. The water pump pulley will not clear the stock crank pulley and the Racing Beat still cavitates over 7500-8000rpm, ask me how I know. We have to tape the front of the car on cooler days to get it to warm up now!

With the new setup, the car just wants to run above 6,500 rpm and will easily pull to over 10,000 rpm. I am limiting it to 8500 rpm to avoid destroying the apex seals, but even steady state running over 7,000 rpm the car still starts to warm up too much.
Thanks for the info.
