lol u should have got a turbo.

i have seen wastegates plumbed into the intake piping to control boost. if u have an large adjustable bov u can just disconnect the vacuum line of the bov and adjust it till it hols 5 psi, i did this when my car was having over boosting trouble. but its noisy.

No as as far as I know they go in the vacum line to the wastegate that turbos use and delay it opening up.
I think some supercharger has by pass valves or clutchs on thepulleys, these could be used...

no but you can always use a bov to bleed off boost, just dont hook up the vacuum line to the top and make sure it is ajustable, so you can ajust it to the boost level you want. 8-)

Im not getting upset. If anything I would be on your side coz I have a charger on mine as well. One of the fastest e-series Falcons is charged and here in Perth. Only diff is his is +ve displacement.

May be a similar set up on the intake pipe like a waste gate or a valve of some sort that would vent at 6 or 7 psi? Im sure a turbo shop of some sort
could have enough ingenuity to come up with something.

I'm not sure what ECU you're running, etc, but you could always set your rev limiter lower, so that its making the 6 PSI you want at say 4,000rp rather than 5,500rpm. That is if you can adjust your limiter.

Or TUNE it to the higher boost level ?
So you want power earlier ???
Isn't that the reason why s/c is better???

I thought that with a centrifigual blower the boost is always going to be linear....

Put the 9psi pulley on, retune and get off the throttle at 6psi :)
