Guys you will have to check with "MAZMART" for performance figures.........Greg if you
have been following a previous thread you will recall that Mark Steitle has adapted the
Renesis water pump to his 20B powered "Lancair ES..........See his post on the subject

Chrissi,
I'm sure you won't have any trouble converting to the Renesis water pump. Just band saw the wp housing from a Renesis front cover. All but one bolt lines up with the 13b front cover. Install a heli-coil in the the one that doesn't line up to any holes in the housing. You may need to make a spacer to get the 13b crank pulley to line up with the renesis wp pulley.
If you don't want to use the stock Renesis thermostat housing Paul Lamar sells an adapter that mates to the Renesis WP. It directs both the inlet/outlet toward the firewall. I welded Wiggins couplings to the thermostat adapter. The main purpose of the adapter is to provide clearance for the p-port slide throttle. If you aren't using a slide throttle, you can probably use the stock thermostat housing.

Same here, if it works and the numbers are good I will buy it. Will it work for a 20B?

I wonder if they have any data as to what the stock flows and what the modified version flows?
I like to know what $265 is buying… :>)

Renesis waterpump with improved impeller for more efficent flow and cavitation resistant at high rpm...........A little
pricey but Christmas is coming !!.......................<:)
The purpose of the pump is to improve on Mazda's design since we are able to precision hand build each unit and have vast experience with rotary engines being raced amid torturous conditions (Having raced and won at 12 hours of Sebring, Daytona 24 hour, 24 Heurs du Mans and won multipe championships). What our pump does is move a greater quantity of water out of the block quicker (As allowed by the thermostat) to be exposed to the cooling elements. This is accomplished by superior design. We start with brand new water pumps from Mazda and install our impeller that we've designed. Our impeller moves more water and prevents cavitation by having much tigher clearances (To every surface), helical shape, closed back and conical introduction. Our design is reminiscent of that used on the R26B 4 rotor engine and does not require any under drive
pulley to slow it down.
