Re: Specs for Compressor - Calsonic 73111FA132 AND discussion on substitutions for Subaru Ej25/22

There ya go Andrew. I got all of your Vanagon threads merged in to a single place. Now you don't have to hunt for them all over the site.

Re: Condenser upside down.

Wow. Working hard at installing a condenser backwards. Your picture clearly illustrates how a multi pass parallel flow condenser works. The hot gas enters the top through a #8 fitting. The gas occupies a large volume. As it cools, it decreases in volume and increases in density. By the time it gets ...

Re: Choosing the right condenser for a custom AC sistema.

Yeah I don't have that kind of flexibility on an A9L ECM. Nice that you can do all of that

Nice.

Being able to pull the fan speed up when you need airflow over the condenser regardless of ECT is handy.

Re: Choosing the right condenser for a custom AC sistema.

Yeah you can't trim the 15229250 with the inducer ring, but the fan shroud is not as important either.

Are you running the 15-4958 electric clutch?

Nice video Chris.

I have had good luck with the GM 15229250 fan if you have room (20 inches) It can be loud with the clutch locked, but it does move the air.

Re: When charging by weight, fill to max?

Old residential hoses with a .250 bore I bet.

4000 psi Imperial stuff is .187 bore nominal.

Re: AC is AC.........Caterpillar backhoe

Saying CAT backhoe is like saying "Chevrolet truck" It could have many different systems. I have found GM V5 / V7 variable displacement compressors on Excavators. Safe to say it could be a few things causing nearly equal pressures on this system. Compressor shaft not turning. Could be a ba...

Re: Choosing the right condenser for a custom AC sistema.

The 14 x 18 condenser is tiny. Without enough airflow it would never work well. Cabin size does not matter with the doors hanging open. The belt drive fan moves enough air to make it all work well. the aftermarket fan moves far more air than the OEM 4 blade ever could. Condensers need good airflow t...

Re: Choosing the right condenser for a custom AC sistema.

Good airflow is the key. I just finished up a 1965 Ranchero for a local. Not a lot of room in that radiator support, so the biggest parallel flow condenser that would fit was a 14" x !8" The usual SD508 clone, and the vintage look under dash evaporator. Typical customer buys the lowest pri...
