it be more efficient to do a twin set up? I would think that it would be easy to plumb two intercoolers symmetrically (one for each side of the car), along with manifolds and exhaust on each side of the car. If you went with a big turbo, you'd run into lag on the track since the transmission isn't going to be able to keep the car at optimal rpms on the track for the VG, right? Versus low lag twins being able to provide consistent power through a wider rpm band.
