Achieving big power with turbochargers is relatively easy, but making huge horsepower while retaining driveability is an enormous task. Peak at the dyno charts and you'll see Switzer's 997 Porsche P800 makes no sacrifices on the road to 800 HP.

I was invited to the Nelson Ledges Raceway in Ohio to test-drive SPI’s latest projects: the Porsche 997 GT2 and Nissan GT-R. Initial laps were treated as a warm-up both for the machines and me, but my pace quickened as I began to rein in all 800 hp from these retuned sports cars.

Switzer have been hard at work all last week fine-tuning the latest version of their 996 P800 PKG. The new Switzer-modified Tial Alpha based turbo design offers a substantial increase in power AND response compared to K16s, and dramatically improved response and smoother power delivery compared to conventional turbo kits with similar power claims.

This past weekend's Milemarker-1 event in Miami was supposed to be little more than a fact-finding mission for us. We were going down to log one of our customers' P800 GTR Nissans in extreme heat, and see what we could see. It was a bit last-minute, but we went into the event without expectation ... and came home with back to back runs over 190 mph!
