After all, we're talking about twin induction for a measly 3.5 liters. The amount of VE loss there is negligible compared to the heads/valves. Again, cams and compression will be required to eke out more N/A power here and that comes with a price on pump gas with todays emmision requirements.

Save your tooth fairy money and wait for a good TT kit. Bolt ons are going to be a joke with this one.
