Re: liquid cooled ht

After all that welding is the bore anywhere near still round or will you have to bore and resleeve it? What are you going to use for a radiator? A heater core maybe?

Re: liquid cooled ht

Really cool project Taco!!!

Don't forget to put some sort of thermostat in the system.

jauguston:

To answer your previous question about the benefits of liquid cooling...

Liquid cooling provides a much more uniform and controllable method of heat dissipation.

With air cooling there is always the potential for hot spots.

Re: liquid cooled ht

Jim,

And it is your belief that the folks that designed this little engine didn't take that into consideration and the lack of water cooling is the reason they blow up all the time?????

Jim

BTW- Where is the head you and then your wife later promised me months ago???

TBH I don't think they took much into consideration when they "designed" these lil engines lol, yet still they don't seem to "blow up all the time" ...for me anyway ;)


*puts mod hat on*

...and I gotta say, if ya wanna discuss product delivery (or lack thereof) with one of our vendors, it'd prolly be better to call him, send a PM or email, and/or even make a post in http://motorbicycling.com/f3/find-dealer-review-1730.html instead of here in someone else's thread as that kinda thing tends to derail the topic quite badly.

Re: liquid cooled ht

What you may want to do is grab some auto parts store ads, I see specials in them quite often that read "Heater core sale! Priced from $10". Just go in and say "I want the $10 heater core". :D

Re: liquid cooled ht

How is the project coming...? I was going to water cool mine by just wrapping the jug with copper tubing and using a radiator from a liquid cooled computer system (Had a fan built in) to cool it down.. only problem is the pump is only rated for 145 deg. So that kinda stopped me. I would like to see this thing work! Good luck!

Re: liquid cooled ht

Griff,

The copper tube idea has a problem. The area of the tube that is actually in contact with the aluminum of the fins is very small. The thermal transfer of heat will be minimal. You might actually find your engine running hotter because the copper tubes will block any air flow. give it a lot of thought before you go to all the trouble of doing it.

Don't forget to use the full cooling capacity of the cylinder head.....fill it up to the brim with ice cold water!laff

On a serious note, it looks good and should work just fine with the right pump. Keep it coming!

Yea, like the old water cooled hit and miss engines, just be sure to take corners at full speed to keep it from sloshing out! :D
