The last time we checked in on Tym Switzer, his Oberlin, Ohio-based outfithad tuned a
Nissan GT-R with 1,000 horsepower. Now the firm is back with its latest street-spec creation based on the
Porsche 911 Turbo. Switzer Performance has dubbed the project F900, a fitting name because it has flex-fuel capacity to run on gasoline, enthanol or a mix of the two - not unlike the
Koenigsegg Agera - banging out a prodigious 900 horsepower in the process.
