    Bringing an old thread to life but I thought from memory the one I used to drive twenty years ago was like 42psi boost with the 525 red top?

    10 pounds will tell you nothing to speak of. You need o air it up and see how long it takes to b;leed down.

    Maybe work for a busted one, no way to see if it leaks like that.

    You can not test one like that it will not build boost in nuetral.

    Great video but a note of caution NEVER put a body part in front of the plug . It can hurt you bad if it pops out at pressure
