Cadillac-Powered Streamliner from Spectre Breaks World Speed Record at 330.7 MPH

Spectre Performance Infidel

This past weekend, the record for world’s fastest gasoline-powered land vehicle was set by Spectre Performance’s 1900 hp SpeedLiner. Powered by a twin-turbo 1970’s Cadillac engine with 1200 ft-lb of torque, this speed demon, nicknamed Infidel, blitzed its way to an amazing 330.7 mph at the Bonneville Salt Flats in Utah at the hands of driver Kenny Hoover. The Infidel was built by hot-rod accessory manufacturer Spectre Performance at the behest of founder Amir Rosenbaum, who has vowed to keep pushing until they reach 400 mph.

The Infidel SpeedLiner is a marvel of creative automotive engineering. The engine was pulled from a 1970’s-era Cadillac and then punched out to 528 cubic inches by CAD Performance. They also installed a pair of 88mm turbochargers. The nosecone was taken from the fuel tank of a Voodoo Canadian fighter jet. The biggest challenge for the Infidel Team was to fit everything inside the incredibly narrow shell. Installing a differential, turbos, water and oil tanks and all of the other components was a true feat of ingenuity.

Amazingly enough, the Spectre SpeedLiner was built by “feel” without the benefit of any computational fluid dynamics or wind tunnel testing. Amir Rosenbaum wanted to run flat out at Bonneville and then see where the salt settled. They will now go back and make tweaks and changes to move the bar forward yet again. This is a great story which we will continue to follow…
