FPS Automotive

 Here are some pictures; more descriptive and technical text to follow. This car makes 303 hp at the wheels. You can contact Doug Lewis for more information on this developing modification.  You can also read more about this car and it's owner on Don Donelson's "Super SHO" page.

The prototype car. It is a '91 belonging to Don Donelson.

Rear of the engine view. Note the relocated coil pack.

Front of the engine view. Note the shaft that drives the supercharger at the other end.

Detail view of modified intake. Um, Doug, the dryer tubing is a little cheesy, even if it does come straight from Vortech and costs $18.00 per foot.

Doug Lewis tests the increased torque.

Naughty! You can do this in a stock SHO, but it takes a long time to get there.
 

SHO Shop

 Powerdyne offers a supercharger for the SHO. The SHO Shop offers two kits (6 psi and 9 psi) that include all of the other goodies you'll need to install.
