315 at the wheels with a V-8 (I know it's a small one) that is twin supercharged is sad, unless it's tuned way down.

Lexus SC430

Under the Hood
An all-aluminum, 300-horsepower, 4.3-liter, dual-overhead-cam V-8 engine employs variable valve timing with intelligence (VVT-i); it generates 325 pounds-feet of torque.

that is pretty bad, that 2 superchargers only give it around 60hp to the wheels. and remember the SC's weren't the only mods done to the car.

as far as twin charging goes, all you would need is a pulley with enough room to pull two shafts, and some custom brackets for them. It's not much more difficult than setting up a TT application in a V style engine. One SC for each bank of cylinders. anyone remember that twin supercharged L88 Vette for sale on E-bay a while back. 800hp in street trim, and 1200hp with race gas and smaller SC pulleys. That was a beast.

I'd like to see the twin charged Mini work out. They did it with a mr2 i believe with great results. SC for lowend, and turbo for high end. it's gonna be a bitch to plub that thought, minis don't offer much room...
