113864, RE: Why go so large in TB when the manifold is so small?

Well, the quad TB setup is a perfect design for a motor that has an astronomical redline, which would require a LOT of air. A motor with a 6000 RPM redline will use half of the air that a motor with a 12000 RPM redline will (well, at redline, anyways), given that nothing else changes (like the VE, etc...). Mind you, in order for a motor to stay effecient at 12000 RPM, those would need to be some NASTY camshafts, and a heavily ported head. At that point, an open header and quad throttle bodies would be VERY helpful.
Me, I'll stick to a this turbo thingie.
