Engine: super charger belt

[K-Hawk]

I have been reading here that one the problems with early water pump wear is the belt tension. Would it be possible to use an electric water pump/ motor thus removing the pump from the belt circuit?

Electric water pumps are used for drag cars, but won't move enough water to work for over a few minutes. It sounds like you are looking for a complicated solution to a minor issue. It's not like water pumps on supercharged cars fail every 20,000 miles or so. I've owed many R2's, but never found pump failure to be a major issue with the HD pump.

I'll toss this out for discussion.....

My take is that there needs to be a surge valve inserted in between the supercharger and the air bonnet/carb box.
Run the discharge to the air intake hose...after the air filter (to keep it quiet).
My reasoning?
I think that the belts get an extreme load put on them every time the driver goes from full throttle to idle (lifts off the gas pedal).
Yes, the tensioner should allow some movement, but the stalling of the supercharger, even if only momentarily, because of the pressure spike between the supercharger and the throttle butterflies....causes the belts to slip, and that starts the slippage process.
Ever hear that belt chirp when you let off?

What'cha all think?
(Note that I didn't say 'blow off valve', as that term drives some people on a supercharged application).

On my R-2 Hawk the supercharger belt doesn't contact the water pump. Crank pulley/tension pulley/supercharger.

To: K-Hawk,----Yes, whoever dreamed up the blower belts- over- the water pump idea probably didn't receive a trophy for 'Engineering Brilliance' that year!
