Just wondered what actually raises the piston/diaphragm. Is it the vacuum drawing it up or the boost pressure pushing it up?

Depending upon the type, both act together. On 26th Jan, 2012 Tom Fenton said:

yep, on most valves if the little pipe comes off it wont have boost pressure helping it stay closed and it will start dumping, mine does this around 15psi. On 28th Aug, 2011 Kean said:

Thanks for the responses. Is there anything available that just works off the boost pressure without the need of the vacuum pipe? I would like to limit boost to 10psi, I already have a bypass valve for when the throttle is closed. Or could a normal bov limit the boost with the throttle fully open? Cheers |
