Pinz cooling

Jake, how did they do? Have you been able to check head temps for consistancy from cylinder to cylinder? I wonder how much time and trial and error was spent back in the Alps getting it right.

They didn't spend much time on it... Believe it or not the system doesn't have very much in the way of cooling at all... The wild thing is this vehicle is designed to work primarily in cold climates and it does not even have a thermostat or any sort of flaps at all, only an oil T stat.

There are no vanes and no deflectors to divert the air where it needs to be and the #2 and #3 cylinder temps illustrate the need for it with no doubt!

I definately have some development to do to the pinz cooling system!

I'm guessing that the pinz is more like an air cooled farm tractor when it comes to the way the loads are put on the engine. With the low gearing it never really gets a long load.

But when you are towing 11,000 pounds with another 2,000 in the back of the Pinz that changes...

The redline on the engine is 4,500 RPM. It's under load all the time but it's designed to be.

It would be interesting to put a quad CHT guage on it (or is it a 6..) those iron jugs really look they would hold the heat, at least next to that beatiful set of Nickies you posted. It would also be interesting just to beat the hell out of the pinz in stock form in the summer just to see how it holds up, then fix it. Some of tjhose heavy duty aircooleds just keep on taking it. ...Like the 50 HP Wisconsin used in alot of farm equipment and in the plaster pumps.
