External Electric Water Pumps Increase HP and Cooling!

These have been on HRC Honda CRF250Rs last year but now we've seen them on multiple 250 bikes. Chad Braun, owner and founder of XPR, explains to Michael Lindsay why teams are running external electric water pumps on their race race machines.

been doing this modification for years on tz250's, rd350 race bikes etc for years. I'm surprised it's not been done on a motocross bike before. great mod for keeping temperature under control and will add about 1hp on a 125gp bike but obviously more during a race when excess temperature is causing a power loss .

Should be added why it improves cooling. The waterpump isn't related to engine RPM anymore while an electric waterpump can spin on full speed all the time. Increased flow means better cooling. It's obviously a bit of a trend now and we'll see if they really keep it on the bikes. It's certainly a performance gain, but it makes virtually no sense to get one for non-factory bikes, as they usually produce less heat by lower RPMs, lower compression ratio, less aggressive cam lobes etc. Very interesting nevertheless!

@keelangerken5154 2 жыл бұрын

Furthermore it can be controlled by the ecu via temp sensor feedback to also regulate engine temp by slowing down or speeding up flow to keep it at the optimum temp for torque or power output

Being outside the engine surely having the air run past it, it would make the pump itself cooler aswell???

It's prob an expensive upgrade.what I want to know is it on constantly when bike is running is it activated on a switch to help cool it between motos.while it's sitting on a stand.does it flow more fluid or just faster flow.alot of questions.

I need one on my K7 750! Not for power, but for better cooling. It's fine on back roads, but as soon as I hit a set of traffic lights well, she don't like sitting there idling after a little "spirited riding"...

Sounds like a good idea my only concern would be if the motor for the electric pump were to burn out you would be in trouble. The mechanical pump is more reliable but who know.

@RadioReprised 2 жыл бұрын

Is it total loss with a lithium battery? Otherwise the drag is just in another form. I like the idea you get full flow even when rpm drops but could you get equal cooling with a larger rad?

It's not total loss.

@actionsportster7686 2 жыл бұрын

Would be nice to them develop better packaging for this. It needs a durable design in a location that doesn't obstruct other components. find a space where it can live ... where the pumps housing, hoses and wiring harness can safely exist and function as a whole to improve cooling and power ... and you will have every manufacturer scrambling to add this to their bikes.

If you watch carefully the video shows 3or 4 different pumps and mounting locations. If your not racing at the highest levels this is probably useless as 99 percent of us don't use the power the bike has

I think it would maybe help a little. But i would question the reliability of the electric pump over mechanical. Not saying it couldnt be reliable but is the risk worth the gain if there is any at all. Honestly even for a track bike and the average weekend warrior i dont think this would be the best modification. Especially because theres only a small small population of riders who could actually benefit to the hp increase. I know my yzf 250 has all the power i could ever need. But hey if they prove this to be as reliable or more reliable as mechanical and make it either stock or easy to install then it would be great

I can see the benefits, but as an enduro/trail rider I'd be worried about it failing due to the electrics (rock/stick/water/electrical gremlin) and me not knowing - I would think mechanical would be less likely to fail instantly. For a pro bike that gets stripped regularly it isn't an issue but not for me.

@codywright1446 2 жыл бұрын

You’re not wrong, but they will likely improve packaging to solve some of those concerns. Most of my riding is harescrambles these days and this could be a game changer imo.

@loopie007 2 жыл бұрын

Sorry, but I would disagree. Regardless of your riding use, water pump failure of any kind is noticed by water spewing out the radiator. 99% of mechanical water pumps and hoses are low and outside the engine. If you could remove the whole system and put a small pump near the center of the bike, it would have less chance of damage from "stuff". These small electric pumps work for years on cars with almost no failures. Then can also run full speed when the engine needs cooling, not just when spinning the engine fast. Great idea. Should have been done years ago.

What did we do here? Get into the realm of thinner cylinder walls on this scooter? If I am another team I am wondering, how are you building so much heat that it became a problem while others aren’t saying they have had to seek alternative temp resolution measures? Perhaps it’s all just a story. Package and sell, but before I buy I need the data on temperature reduction levels from speeding up the flow inside a closed loop system. Same hot water simply moved faster does much? It would seem air flow improvements at dissipation points (and/or increasing dissipation surface area) are still where the biggest progress can be made in temp reduction. This screams we are battling big bore temperature concerns and found progress at idle speeds, or we’re playing with something to sell. Unless you buy into impeller drag and seal friction improvements being a big enough power improvement reason to run one of these while the massive crank seals and huge clutch basket bathing in oil are still 99.9999999% of the drag. Did I mention the countershaft seal?
