that looks really cool. I wonder how long that motor would last like that though.

If he tunes it right it should hold up just fine. So long as he keeps the boost low on both the blower and turbo. The 4G63 can take stupid amounts of abuse without letting go.

Is it worth the performance though? Wouldn't it be better to have either a single turbo or single supercharger boosting in higher amounts?

Thats just it. I would think you could do better with a bigger turbo. Problem is Lag. You could bassically eliminate boost lag. I don't really see the point though in an AWD car that launches at like 6k RPM. I have seen it done on several MR-2's though. They had crazy powerbands with a torque curve to die for. The set-up isn't so much about peak power, as the powerband. If you do it right, you can have zero lag from the S/C, then just as the blower starts running out of breath up top, the turbo is spooled up and takes over. Probably more effective on a car that revs really high and can really take advantage of the benefits of both power adders. I could see it being really useful on a road course or autox car moreso than a drag car.

You figure Zooomers red GP ran 9.9 or 9.8 twincharged. Thats also without wheelie bars. Only 9 second GP IIRC without them.
