I.M.P.B.A. Sept. SAWs

I'm told the key is to super cool it before the run. now this comes from a very smart pencil pusher, so who knows. All I know is he has way more functioning brain cells than me

[Doug Smock]

Warm cells and a frozen motor.

I'm told the key is to super cool it before the run.

I don't doubt that for a minute.
I'm going to give Mr. Neu a call and see if there will be any ill effects from freezing the can and stator of one of his motors.
It is possible to build an evaporator to install on that motor. Then all a guy needs is a jug of 404-A and a recovery system. Just so happens, I have both.
We might have to do some testing in that area.:D

You need to be a little careful with the super cooling. If the esc isn't REALLY water proof, the condensation that forms on the cold parts can short it out (ask me how I know).

Forgive me for kinda hijackin the thread. I kinda lost sight we where disscusing advantages for saw setups. My app is more for endurence races. One of the things Im trying to do away with is drag from pickups and intraducing water into the hull. Not to mention real radiators tucked into intakes with running fans would look really freekin kewl.

It's a shame the government won't let us vent refrigerant anymore. A clever fellow could store enough onboard to keep things pretty cool for at least a mile.

Brian, Did you see anything noteworthy while you were cooling things off?? (other than the smoke from the ESC)

Laws are made to be broken! J/K.

Also wouldnt the oil on the motor bearings get a little stiff under super cooled temperatures? I may be way wrong but have not kept up with oil tecnology.

My father was in the refriferation business way back. When we did summer house calls the number one problem was dust in the condensers. We used the high pressure in the freon tanks to blow out what we couldn't reach with a vacuum. That's a big no, no today and would be an expensive way to do it. Back than a tank of freon was about $15 bucks now I'm told its 4-5 times that.

[Doug Smock]

Yep,dirty condensers are the #1 cause of system failures and the easiest service to perform. People don't think about it until they have a problem.
You DON"T want to get caught venting refrigerant. You can be fined $10,000 and up to 5 years in prison.
R-22 is $46.00 for 30#. Last I checked R-12 was over a grand for a 30# cylinder. I haven't purchased any 12 since 1995.

[Steven Vaccaro]

Doug my father wanted to ask you if they are producing r12 any longer?

[Doug Smock]

No sir, they quit producing 12 several years ago. You can still buy it, but it has been "reclaimed". The virgin stuff is gone from the wholesalers.
If I remember right, they will stop production on R-22 in 2030.

What about the small c02 tanks they use in the really small paint ball guns!!!might work


just thinking

[SJFE]

If it where the carbon fiber tanks that may work. If I remember correctly from my painball days the carbon tanks where for No2 only. I dont know of you can co2 put in one of those tanks.

I have a shocker that was setup with a carbon wrapped tank because it was short and fat with a ton of volume. We used co2 in it. Some places wouldn't fill the tank. But that wasnt a problem since I brought my own fill station with me.

[Doozie870]

I havent seen the thread/artical but Rod (hydronut) was telling me about a Nos system kind of like the ones from tower for nitro trucks,that guys had modified for FE use, non flammable non corrosive as far as I know.
Didnt mean to distract the thread with this, just trying to help my saw cousins!

[Doozie870]

good luck everyone, let em shatter!
