Need for hi flow water pump?
Other model mazda water pumps are known for cavitating at high rpm. Since b6/bp aftermarket internals are coming down in price (rods, oil pumps, etc), many of us are starting to build motors capable of high revs. Curious to hear feedback about a new, hi flow water pump? Do you think it's needed, and would you buy it for 2X the cost of a OEM pump?

I doubt it's needed. I would be interested to know how many HP a wp pulls when the motors turning 2K, 5K, 6K, 7K, etc. From what I've read mechanical wp's and fans pull more and more power the faster they spin. For example Moroso sells an electric water pump that replaces the stock one and says it pulls 7 amps and adds up to 20HP. If we could find another 10hp or more with an electric conversion, that would rock.

Something like that and adapt it to turn our pump. Maybe sell the stuff to adapt that kit to work on a miata or something. They say mechanical pumps pull 15-20hp at high RPMs, plus it's more rotating mass the motor has to spin, it would probably help response as well.
Edit: it would be cool because you turbo guys could program it to stay running after the engine shuts down to cool the engine a little and cool your water cooled turbo too. I might buy an electric kit and see if I can make it work

For double that price I'd be interested.

The problem is going to be caused by engine speed, not engine power. Though higher power will exacerbate the problem. Since so many of us seem to be building 8k capable motors, I wanted to throw this possibility on the table.

I believe the rotary water pump is $225, but please don't hold me to a price point at this time. This is just exploratory at this point. But what we DO have working in our favor is the BP core pumps cost about $25/ea less than the RX pumps do.

FI cars already have overheating issues on track; I'm not sure how much I like the idea of reducing overall water flow.
I would be interested in a high-flow, high-RPM pump if it would help reduce temps; I would not be interested in anything that reduced flow.
