Switzer Porsche F900
The Switzer F900 is a low-emission, 900 horsepower, flex-fuel monster of a Porsche built by a pack of wild-eyed savants in the middle of rural Ohio … but the story behind this first F900 started a few years ago. Switzer isn't talking about their first cars – those fast and furious DSMs. Forget about those high-horsepower Eagle Talons and Mitsubishi Evos that terrorized the streets and strips of Ohio. Forget, even, about those first Porsche few “rescue missions” to put right what other shops had put wrong. Forget about all of that – because the rest of the world has. As far as the rest of the world goes, the story of Switzer Performance and the Switzer F900 Porsche begins with Sledgehammer.
The Switzer Sledgehammer, of course, was a thousand-horsepower, all-wheel driven 997 Porsche Turbo whose YouTube fame was assured with a series of 9-second passes and a standing mile top speed of nearly 200 mph. The most impressive part of the car, however, wasn't a quarter-mile time or a TexasMile certificate … it was the engine. “The engine,” explains Tym Switzer, “was 100% Porsche. It was bone-stock.”
Most engines, even those emblazoned with storied and iconic names, could never stand up to such abuse. Not for long, anyway. The 997 Porsche Turbo's engine, however, is not like most engines. “The 996 and 997 used an engine that was designed for GT endurance racing,” says Tym. “Porsche used forged internals, beefy connecting rods, and a hundred other tiny detail changes to make sure that engine, in its full-race GT1 configuration, would put out massive power, hour after hour, race after race. It was built for this. Porsche built it for this.”
The Sledgehammer begat the P800, a streetable, comfortable, 800 hp pump-gas conversion that turned a “regular” 997 Porsche Turbo into something really special.
Right about the same time that Switzer's R911s started finding homes, however, another Switzer “skunkworks” project had started to steal some of the R911s thunder. It was a Nissan-based project car called the E900, and the “E” stood for Ethanol.
“The E900s took advantage of some of Ethanol's unique properties, like high octane equivalence and cooler burn, to make over 900 horsepower without relying on toxic race fuels,” explains Tym. “They were great cars to work on and dyno-test, actually, because they were so clean your eyes didn't water the whole time you were running them. You could finally breathe in the shop with the dyno going.”
It wasn't long before the Switzer E900 GTR conversions caught the attention of one of Switzer's Canadian clients, who happened to be driving a different Switzer car … one of Tym's first Sledgehammer 997 Porsche Turbos. The very same Sledgehammer, in fact, that still holds a number of informal “forum” records for stock-internal quarter mile e/t, 60-130 mph time, and standing mile top speeds. A serious car, in other words, and a serious driver. A driver who'd experienced a lot of seat time in a fast, famous street beast who had come to expect bulletproof reliability and bullet-like speeds … and he wanted Switzer to build him an ethanol Porsche.
What you see here is just that. The Switzer “F is for Flex-fuel” F900 Porsche 997. A car that is part 800 hp pump-gas Switzer P800 Porsche, part R911 race-ready Switzer R911, and part Sledgehammer – when the mood strikes the driver, of course. “Until then, the car feels just like our other P800 cars. It's just like stock, except it just keeps pulling strong after the stock turbos have given up. Once you get it on the ethanol, though, it really takes off. Just like the race gas cars.”
Visually, the F900 is a standard 997.1 Porsche Turbo with a few decals hinting at something special – but one look into the engine bay does much more than hint. The new car features Switzer's MONSTER intercoolers and CNC_machined y-pipe intake, as well as proprietary Switzer turbochargers breathing through Switzer's “standard” 997 sport exhaust. The flex-fuel techno-whizz-bangery is handled by a series of specialized senors feeding data back to a stand-alone ECU solution that adjusts injection and timing on the fly, ensuring an appropriate tune for whatever fuel is handy.
