just wanted to say that the cheaper one (link i posted)--

states the max vacuum is
28.3" of Mercury at Sea Level @ 90 Psi

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 ...

its just a car to get from pt a to b usually it does it nicely --AIM: chronon1 95 Tour SE, 2.5 lliter 24V DOHC V6, 5 speed manual
