I know that these guys are a Yank company but that is quick, 0-60 in the mid 2's.

Switzer Performance Innovations (SPI) of Ohio, USA, is a renowned tuner of Porsche products, specifically for the Porsche 996 and 997 models. At some point SPI, through owner Tym Switzer wondered what the limits of a tuned 997 would be, how much horsepower a stock engine could take.

Soon SPI was working on this ‘experiment' and the results are here for all to see. The car aptly named the SLEDGEHAMMER makes over 850 all-wheel horsepower running on racing fuel. That translates to over 1000hp at the crank. The figures were produced from a 997 twin turbo engine through extensive ECU tuning, the use of SPI-developed headers, a sports exhaust system, an intercooler package and SPI-tuned GT30R turbos. Every part of the system was constantly metered and tested by SPI during development.

On tar the SLEDGEHAMMER creates something close to what would be considered magical numbers. The 0 - 60mph time is consistently in the mid-2 seconds, and its massive tractability is shown by a 60 - 130mph time of less than 5 seconds. The quarter mile is trashed in 9.796 seconds and 195mph was almost achieved at the Texas mile, an abandoned air strip in Texas.

Any interested party can purchase himself a SLEDGEHAMMER package for US$49,990 through SPI's website.

Wow…. That’s some good performance. That’s a HUGE intercooler

Oh… and sledgehammer was the name of the corvette that did 400kph….  Back in the 80s or early 90’s?

Huge claim of mid 2's, would have to have some serious traction. I wonder about reliability. Non the less. Interesting config.

Yeah, nice video. Have a great dyno video of an Audi Twin Turbo RS6 engine being tested at the ABT Sportsline factory in Germany. (ABT Sportsline available in Australia). Have to post it on YouTube, one day. They literally try to kill the engine as a proof of their tuning capabilities and famous reliability. Also drove their family station wagon tuned to 700 horses and filming just on 300 km/h on the autobahn. 0-100 in just over 3 seconds. Shame we have limited places where to enjoy such beasts in Australia.
