> Whisper air control valve by Second Nature (single) #56001 $3.39
Yesterday afternoon, I bought one of these at the local Petsmart and rigged
up my own testing system to check it out ... turns out that it's not really
a regulator but merely a control valve. As such, it doesn't clamp pressure
at a given point but bleeds off a fixed percentage. This effectively means
the more boost you have, the more timing advance (or less retard, depending
on how you look at it) you'll get, which sounds backwards to me.
Has anyone else looked into this yet or have I overlooked something here?
