I have a 2000 VX with what I believe is an Alpine supercharger. Anyway its an Eaton M62. I was just rebuild and has a new pressure release valve. My problem is no boost . I installed a vacuum/boost guage. I get -20 on idle. Full throttle I get 0. When I blip the throttle I see the pressure release valve close momentarily and reopen and stay open. When I floor the throttle it does the same thing. I looks like there is not enough boost to allow the valve to close or too much vacuum. There may be a problem with the the way the vaccum lines are run. I have all the lines after the charger connected together (Fuel pressure reg, release valve, and intake manifold) and every thing pre-charger connected. Does anyone have clear picture of the vacuum/boost routing on a Alpine system?
