this is some 'murican experience here but i have seen supercharged v8's go to around 800 on dual two and half over that you need bigger pipes so since you are on a stock motor and realistically shouldn't be shooting for more than the 5-600 range you may be surprised. supercharged cars can do funny things in the exhaust compared to turbo's. other than that one point your exhaust looks pretty open so you never know you could make more power with that restriction in there than if you slapped up a dual 2.5" Being that the rotrex chargers are centrifugal and there map seems to be geared more for smaller flow this may actually be pretty likely, then again you have two of them.
