It does sound like a lot, but ... In around '87, Performance Bikes did a test using a GPX750 motor, and measuring the parasitic losses from various components. I'm far too lazy to try and find it, but if memory serves, the water pump sucked up about 3% of total power.

That said, it was over 25 years ago, and I'd imagine that water pump seal technology has moved on since then. Worth a try though, I reckon.

Cheers,
Brian


Do not walk behind me, for I may not be leading.
Do not walk in front of me, for I may not follow.
Do not walk alongside me, for the path may be narrow.
Just piss off and leave me alone.

In my opinion you will just ruin the water pump. If you want to do something just replace the mechanical water pump with an electric one and measure the gains.

I doubt you will see 5hp even with the stock water pump completely removed.

But with electric water pump u will benefit from consistant temps and flow of coolant instead of stock goes faster as u go faster wen u realistically need most of the cooling wen your stoped at stop light or traffic.

Curious if you have a link to a decent Electric pump? I have an overheating issue on my ZX-7R and have married it down to the pump, radiator, or oil cooler. I wouldn't mind trying an Electric pump if they're reasonable.

I may not be perfect, but at least I don't ride a Suzuki.

Get a chep heater pump from a big car,I got mine from an X5 BMW SUV for evaluation purposes.

Then if your problem is solved you can buy a pump with a controller and remove the thersmostat etc.

Can't remember, I'm afraid. The guts of the article was looking at where power generated from the end went eg. if the fuel / air mixture created 105 hp, and if there was 75 at the wheel, where did the other 30 go ? Friction, heat loss through the exhaust, trnasmission losses, all that kind of stuff was covered.

Will see if I can find it sometime over Summer.

Cheers,
Brian
