Tym Switzer has been quietly running Switzer Performance Innovations (SPI) in Oberlin, Ohio for several years, building show-quality exhausts and bolt-on performance products for twin-turbo Porsche 996 and 997 models.

With his latest project, Tym and the crew at SPI wanted to test the limits of what would be possible with stock 997 internals. His crew had no problem getting 700 wheel horsepower from 997 turbo engines. This was not enough and they wanted to go a bit further.

This led to a project called SLEDGEHAMMER, that is a bolt-on performance package for 997 twin-turbo Porsche’s that delivers over 850 all-wheel horsepower on race fuel. That’s over 1000 hp at the crank!

Switzer reports that (despite backing off the throttle early) the first SLEDGEHAMMER went almost 195 mph at the Texas mile. Additional performance figures read like the stuff of legend: consistent 0-60 times in the mid 2’s, less than 5 seconds to go from 60-130 mph, and 9.8-second quarter mile elapsed times with trap speeds regularly in excess of 145 mph.

In addition to extensive ECU tuning, the SLEDGEHAMMER package includes SPI’s in-house developed headers and sport exhaust, as well as SPI’s MONSTER intercooler package and SPI-massaged GT30R turbos.

The SLEDGEHAMMER package retails for 49990USD, more details available at Switzer Performance Innovation homepage.
