Hydro-aspiration?
I was just wondering if anyone with a water cooled motor is using some sort of water aspiration to cycle water through their motor more rapidly?

RE: Hydro-aspiration?
Actually, you don't want the water to flow through the engine too rapidly, you will wind up actually overheating the engine. If the water flows too swiftly through the engine, it will not allow good heat transfer thereby overheating the engine. We have seen this a lot in full scale boats where people remove the thermostats from their eninge.

RE: Hydro-aspiration?
Hydroaspiration is when water is passed through a tube at a high rate of speed, if a hole is placed at a ninty digree agle into the tube that the water is passing through it creates a tremendous sucktion. What my idea was to make a turn fin on my 1/8 scale hydro with a reverse waterpickup port in the lower part of it. As the fin goes through the water it would create a sucktion that could cycle more water through the boat..... I do understand about the water being passed through the boat to rapidly it will not cool it, how ever the rate of flow can be slowed down with different size hoses, couldn't it? Just exploring a new idea that I have not heard of....

No reason not to try it but personally I would rather pressure feed than suction drawn.
Pressure feed does not create much in the way of drag and is pretty reliable.
sucking water through the system would still a water pickup though wouldnt it ?

Yes, thats an idea.... what valve to you use, and where do I find one... have any pictures....? are you using a aspiration type setup?

I would be pressure feeding and suction feeding at the same time, that is why there would be so much water being cycled through the engine and components.... A larger tube after the head would slow the water down before being sucked out....

One negative to this system is that in the event you get debris or whatever obstruction into the cooling system and lose flow, you will not know about it until the engine overheats and stops. With the more conventional pressure systems, the flow is visible by the discharge of spent cooling water overboard.

RE: Hydro-aspiration?
yes, gofast you are probably right. I just wanted to explore the possiblities of getting more water through the motor to cool it down even more. Super cooling + super high octane + ceramic coatings= more hp..... That is all I really wanted to know. I was unaware of the water going through the motor too fast and not able to cool the motor, until I started this tread. I will reframe from starting stupid threads from now on.

RE: Hydro-aspiration?
the only stupid question is the one NOT asked,I'm relatively new to the r\c boating scene,(8mo.),and I ,as well as others learn from these not so stupid threads...

any kind of air/water valve adjuster that will still flow the same volume of water when completely open. I havent found one that i like yet, but am still searching. Right now im just using a T-fitting with a screw...not the best but works fine.

Wharehouse Hobbies has a inline fuel valve that would work: http://www.easycart.net/whobbies/Fuel_Systems.html (second item)
