Still, twin turbos are the shizznit. Amazing car you have there.
Kenne Bell is certainly an option though one most closely associated with Mustangs. Magnusson also makes larger superchargers too though and there's always the centrifugal type too. Hands down a turbo system is the most efficient though it does have a different 'personality' than driving a supercharger based system.
