ooooh...ok, here we go again!
i think there'll be lots of 'just put a turbo on it' in this thread, but hell, I think twincharge is cool
You'll need valves in the system, to bypass when one thing is flowing more air than the other. I think the simplest system is:
Intake:turbo:SC:Manifold.
In which the SC is always running. Now, maybe the turbo will flow more air than the SC can possibly have stuffed through it, but I think this is how the HKS kit did it. On the plus side, the car will always respond the same, just as if it was a bigger motor with a turbo on it. But maybe the SC can't hack it, and it will definitly act as a restriction in the system eventually....
Slightly more complicated:
Intake:turbo:Bypass:SC:manifold
So when the turbo's really boosting, air is diverted around the SC. I guess you could turn it off, or keep it running. But now, when you back off in a hurry and get back on the power (like in a corner), you're opening yourself up to heaps of bizzare things to happen. Odd power delivery, sudden jerks, etc. All the things you don't want So maybe the solution is some sort of electronically controlled valve, which is also linked to a small computer which controls the SC. In this way, you'd have a little control over what was likely to happen when.
Then there's all the other options, like having the SC before the turbo, etc.
I think the key to it is going to be a really good valving setup, controlled electronically, so that the car always responds predictably.
*edit* I tried to rep you for starting this thread...but I hit 'enter' halfway though leaving a message and my computer freaked out. I *think* you got it
