which .. is not enough according to contourholic ? ..

=but they don't say if u run it higher how much more vacuum u get :

Air pressure - 75 PSI Min.,180 PSI Max.

Air consumption - 4.2 CFM @ 90PSI

4.2 cubic feet a minute sounds like a twin cylinder pump of at least 1HP or so ... I know mine is that and get's pretty damn hot after about 10 or 15 min.

if your doing it once a year i guess it could be a viable option .. BUT i would like to see them state 29.9 " Hg for whatever higher pressure ... we do enough guess work .. leaving that to chance or guess is just another variable in a world already overfull of them ...



If you have A/C Gauge set, you can pull the vacuum in stages. Run the compressor (for the air powered VP) for 10 minutes. Close valves, rerst the air compressor, the run again. Will take longer, but it sounds as if you have some time and a place to mess around.
