Re: ED supercharged
Is a smaller pulley available for your setup? If so, you could probably get it to squirt out some more PSI, but your blower might not last as long. If you have a Powerdyne unit, I suspect it's already maxed out at 6psi.
What's your air intake like? What's your fuelling system like? Might be time to upgrade to a larger blower.
As for the head gasket, an AU steel gasket should do the trick, but unfortunately since it's thinner it'll add a little to your motor's compression :(
