what a pass
amazing dyno sound
Switzer Performance Innovations (SPI) of Ohio, USA, has made one mean drag strip ass kickin 997. This monster named the SLEDGEHAMMER makes over 850 all-wheel horsepower running on racing fuel. Can run 0-60 in the mid 2 second range 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. 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
