aarang Posted May 18, 2009 Share Posted May 18, 2009 Hey guys, my car is a 1980 ZX with the non auto climate control A/C and heater which is still vacuum operated. It has a turbo motor at 10 psi of boost. I am wondering if I am damaging the vacuum pots which control the heater under boost, because they were not designed for turbo applications. Has anyone run into this before? I have been running the turbo for two years with no dire effects as of yet.... all still works OK. I was thinking of putting a check valve in line so the heater only sees vacuum. Anyone done this before? Thanks in advance... Aaron Quote Link to comment Share on other sites More sharing options...
nismopick Posted May 18, 2009 Share Posted May 18, 2009 They are the same controls for turbo & n/a ... many people are running 10+ psi boost on a conversion... They just don't move on + boost ... only vacuum. Quote Link to comment Share on other sites More sharing options...

aarang Posted May 21, 2009 Author Share Posted May 21, 2009 I don't think the controls are the same for turbo/non turbo (non auto climate control) as I have dismantled both types of cars. Similar, yes, but not the same. The turbo also has an external vacuum pump to actuate the controls when under boost. Anyway, I have already installed an inline check valve to make myself feel better!
