Peter, Top notch work as usual

Thanks Douggie......................

Jeff all my boats are for sport running and never pushed to the point where absolute cooling would be an issue , I agree 100% with Jay also and if compitition running is ever in the works setup would would be slightly different , I almost enjoy building the boats more than running them so I admit to being a little anal with the machining and every little detail........

The best flow pattern is water entering at the lowest point and exiting at the highest point. This ensures the fastest and most complete replacement of heated water out of the jacket.

That is a GREAT point Fluid. Is there ever going to be an end to learning the basic details of FE?

After looking at the my existing jacket designs, the water exit should be at the highest point on the motor, as the hull or motor mount clearance allows. I have some work to do.

Jay (Fluid)a very good point. Reddy, I had all my water cooling lines the reverse of what Jay details and the reason I did this was an easy way to remove the water in the lnes and jacket after a run. I guess it is time for me reverse my lines.
Thanks Jay

Wish I could still update this thread "Ideas on Building a reliable BL System. I would like to add this info about the mounting position of a water jacket exit line.

K so what I'm reading here is every one has there own way of placing their hoses where they think is best, it's always been said "experimenting is half the fun".

I guess from what I see it depends on your setup and if you can place the outlet on the highest point, but from what you said Douggie, your set up worked too. So does it really matter as long as you have good flow?

Why take a chance of getting air trapped in the water jacket? Place the water exit at the top and force the air out as it fills with water.

Reddy I doubt a reliability issue is warrented here , hell 3/4 of the waterjacket manufacturers do theres virtually the same way and I have yet to run into anyone unhappy with the water pickup placement or having severe cooling issues because of it , If you take a garden hose at any angle and spray it on a round object you will notice that it spreads out like a water ripple so trust me the top is still getting cooled , this will certainly be something I am going to test in the spring with a heat sensor on the top inside of the motor to see what temp differance there is the way I have mine and Jays setup . no its not a 100% efficient like Jays but I will certainly live with the 90% it supplies , if you look closly at the mount also you will see the they both have 8 mount holes so Jays cooling setup could be duplicate in less than 5 minutes just by rotating the motor , in fact to make things interesting I am going to rotate the motor with the pickup in the worst possible position and the best then record the differance and go from there , I like to try things myself just to see if the said way holds any water .

This I am not disputing , yes Jays pickup placement is 100% efficient , I just want to see differance there will be between the two , 100 degree's , 50 degree's maybe 5 degree's.................??

Example of testing the common belief
One thing that didn,t make any sence to me was that I had to have a thrust bearing on the motor and the strut , if I used a square end ferrule and square end flex at the strut with only a thrust bearing there it wouldn,t work the motor had to take some of the thrust , what did I discover..........It worked just as good with just the strut taking the thrust and the flex floating in the strut , been using this setup for two years now without a single handling issue in fact all my setups are converted to this so sometimes it pays to try things yourself just to verify it


Ok I will step of my soap box now hopefully without my shoe in my mouth..........................

[ReddyWatts]

Thanks for your opinion Peter. I just really liked what Jay suggested, it makes sense and seems more efficient in cooling the motor. Never thought about the possibilty of getting air trapped in the water jacket. Air rises in water, so placing the outlet at the top will allow any air in the jacket to escape easily.

Reddy I hope I didn't come of like a jackass but I am curious at what point the pickup start being a cooling issue

[ReddyWatts]

No, you did not, that is what is cool about this forum. We come here to share, discus and learn, so keep it coming. It would be boring if we all agreed about everything. ha

I really like your motor mount.

Thought you guys might enjoy a little video on what goes into making one of these mounts.............

Peter, did you ever do an evaluation on the water input/exit temperature discussion.

Cheers,

Not yet Douggie but I think I will this weekend . I have built a test stand fully watercooled with a ubec powered pump and reservoir to test my lipo's with various loads . The motor can be set with the cooling tubes upright , at 45* and at 90* . I will post a video of all 3 runs with the camera glued to my laptop in live mode . I will start each run with the ambient temp at the same level .

incrediable is all i can say !!!!!!!!
