Re: 86 Bronco 134a all new system can't get better center vent air better than 50 degrees

Way too much hysteresis in these new switches. Adjust the cycling switch to turn ON at about 35 psi. The evaporator does not need to spend long above 33f to de-ice in a cycle. Ignore the "off" pressure. Right now you are averaging 37psi evaporator pressure - 40f Blow warm air over that and...

Re: Thanks for the add and RV2 questions

I usually gut those. It is easier on the ones with a tube that goes straight through - I bore the tube out & run a tube straight through the can & braze the tube to the ends of the can. It still looks OEM for a 100 point car - just a straight through tube in reality. With the angle fitting o...

Re: Thanks for the add and RV2 questions

Several ways to deal with this issue, but it depends on the actual muffler in question. Mopar bought parts on the open market & used whatever was in hand - so if you cold post pics of the mufflers you are dealing with it would be a big help. As far as the trash in that line, it has the lowest ve...

Re: A slightly differnt A/C system

The Peak lost it's luster for me when the ninnies paved it. Older records should be considered on their own merit, and Paved Peak records listed as a whole new event. No, the blown flathead will go in a light motorcycle frame - here is the slipper clutch I built for it: . http://ffv8.com/uploads/3/4...

Re: A slightly differnt A/C system

Yeah, I always wondered about that. I guess in 1970 the evaporators were just oversize to account for the added oil - he only thought there was an actual benefit. The oil leaving the compressor is carrying the heat from the mechanical parts, while the refrigerant leaving the separator goes on to the...

Re: New Sanden squalling above 3000 rpm

You could go with a nice V5

1985-86 Cavalier, 1985-91 Grand Am.

Or ignore it & buy a better audio system.

Re: A slightly differnt A/C system

Lots of experience over the past 45 years. Screws were just part of it... I remember the engineer from Harrison Div. that was teaching the RSES courses explaining the theory behind a 12 to 15% OCR. He explained that the oil became saturated with R12, and foamed in the expansion process. If the syste...

Re: A slightly differnt A/C system

Yeah, we used to make some tiny refrigeration stuff - all 400 hz power. High speeds, light weight. There was always 400 hz available if there was a turbine on board. With all of the PMDC stuff that is around now, it looks easy... until you see the electrical racket produced by the digital electronic...
