Billet water pump, who's interested?

I still havent ordered up your newest parts. I think it sounds like a great idea. Not that i need one. I havent had any issues with over heating. Then again I shut it off when not moving or waiting. I see people buy for three reasons:

1. For the cool looking cover only.
2. because their bike overheats every once in awhile or always when in tight single track. might buy both impeller and cover.
3. complete falure of the pump.

right now i would fit in the posser section of option 1. You know i like the bling!

for me it would depend on the price and future issues. For others, I think it would be great to offer this. Just another great and sometimes needed aftermarket part for supporting the line. Im supprised no one has done bigger radiators. Or at least Larger tanks for the bottom of the radiators. If someone fabed up larger tanks, you could take it to alot of radiator shops in town to have them welded up. or juts cut the bottoms off halfway and evtend the bottom about an inch or two to add more fluid.

I really like that between a few of you guys, yall have cornered the market in the husky aftermarket. I like it.

Clay.......I am IN, name the price (within some reasonable amount of course). I have seen the boyesen and other HiPerf type impeller/cover types this sounds like a good move.
As for now the good crew at GP motos will let me salvage a used one off one of the race motors tonight,,,which is no sweat and will get me through this weekends appointment at (RynoLand). R

Mike there are larger rads out on the market, I can't remember the company,,,its on a Mike Kay post somewhere. He has one on his bike if I recall correctly (yes just one along with the other OEM)

I am sure you folks know much more about it than I do, but in my experience a higher flow rate does not always mean better cooling. The fluid needs to stay in the radiator long enough to cool the desired amount. I guess I will have to take off my impeller cover and check to see if mine is in good shape. If I need one and an aftermarket one is priced similar as a factory one, but is superior, seems silly not to get it. Ken

i have had experiance with that but only in my car. Never had the problem in the bikes though. I had a high flow water pump, thermostat and a huge radiator. I overheated worse than before. After talking to alot of the shops, it was decided I was moving the fluid to fast. They said the antifreeze wasnt sitting in the motor long enough to transfer the heat from the motor to the fluid and carry the heat to the radiator. I changed to a 190 degree thermostat, (higher temp than before and not a high flow) and it was solved. So it can happen

Ill look into that. thanks.

If you can make parts that truly will lower the operating temp of my bike, I'll buy them.

For me if it meets or exceeds OEM engineering design parameters in both strength and efficiency I am in all the way. Wait that is exactly what motorhead said. Sounds good.

Haven't heard of this issue on '07s, so this is primarily a '08-9 problem?

I'll be interested in one for sure.

I believe that George and Mike have given the advice of slowing down the flow rate to improve cooling on these bikes. I am by no means an expert, but if one of them care to chime in, It may help Clay improve the impeller for cooling.

How about making a variable vain impeller,,,,,,like they make some turbo turbines...To put it in laymen s terms,,,,its kind of like a flex fan for a car but instead of having the blades flatten out when the RPM's increase the blades actually get a steeper angle when the RPM's increase. I have an idea for a design but it would be a little hard to make.

Is it possible to play with volume & efficiency (lack of cavitation)?? I mean increase volume but lower velocity???
It's late, I'm tired & idea's are just poppin into my head

You could do that,,but that would also mean the velocity in the higher RPM's would also be lower,which also might cause problems with over heating because the fluid isn't being sent through the rads fast enough.

You mean like George & Mike's theory about slowing down flow for more cooling time in the rads??? :smirk:

It would be interesting to have three or so different blade pitches, a temp gauge & some real world testing

Yeah,,,,,just like I said a few posts up. When the motor is at a lower RPM the blades of the impeller are almost completely flat so they hardly move any fluid....but when the RPM's increase the blades start to turn outward(the pitch starts to increase) in turn moving more fluid,,,make seance....

Kickstand out for prototyping work?

1st,,,,I dare ya to remove those cyl fin damper rubber hose things on yer Austrian air hammer!!! Its like ringin church bells!!!
2nd works connection still makes weld on foot peg wideners (I forgot how small they were),,,K this is all tongue in cheek of course. riiingg diiiiing

PS I would stick close to the OEM design parameters on the dims for the impeller. I am sure they computer modeled a standard parameter for avg speed,air flow through the rads, cooling efficiency of the OEM coolant, flow rates and flow speed to capture the heat from the engine and lose enough to the air based upon all of the above. That said,,,,,,my darn bike was friggan overheating with 30%race fuel, and Maxima cool aide with slightly on the (safe) rich side jetting. All that said,,,mostly in jest,,,Once ya got it dialed in I will gladly go for some functional bling!! Thanks R
