Found This At Hot Rod Magizine website About” Pegasus”:
The Turbonique exhibition match-race fleet also included Jim Costilow’s Turbo Stang Mustang from Pennsylvania, Gene Canham’s Turbine Dart from Chicago, Jack McClure’s Sizzler Z16 Chevelle from Florida, and Roy Drew’s wild 183-mph Black Widow VW Bug, which crashed and subsequently appeared in full-page Turbonique magazine ads of the day
Did Some Digging …Not Much available ,But Heres what Phil Burgess wrote in the “insider” http://www.nhra.com :
“Turbonique exhibition match race fleet of cars that also included Jim Costilow’s Turbo Stang Mustang, Jack McClure’s Sizzler Z16 Chevelle, Roy Drew’s Black Widow VW Bug, and the Rauth & Venetti Pegasus Mustang. According to an article in Hot Rod magazine, the Pegasus “burned a pressurized mixture of Thermolene, nitrogen, and oxygen, the insane speed of the turbine output shaft was tamed to 7,250 rpm by an 8.3:1 reduction gearbox then fed to the quick-change rear axle and slicks.” I also found an article in Garage magazine that clarifies that these cars used “Turbonique Drag Axles, which appeared to be a center section for a quick change differential, but with a mutant spaceship tumor growing from its hinder. That tumor was, in fact, a rocket engine providing direct drive to the rear axle. When not in use the car would drive under conventional power through the front driveshaft. When the driver hit the ‘panic button,’ the rear-mounted rocket immediately engaged and began channeling One Freaking Thousand Thermolene-addled rocket horsepower to the rear skins. Total weight: a scant 100 pounds. It was advised that the driver keep his thumb on the switch during operation since, having no clutch or fuel metering, the only way to control acceleration was by shutting off the fuel supply.” Turbonique, of course, also went on to help blow the minds of race fans by teaming with “Captain Jack” McClure on a wild rocket-powered go-kart in the 1970s. “……WE HAD McClure at Dover …Had Velcro on the back of his fire siut to “stick” him to the Kart !
Bud Faubel had a Turbonique axle set up on one of his hemi ’65 Dodges, it just boiled the tires, while running MPH’s almost as fast as the fuelers.
I never saw the turbo kart at Dover, but did at Lebanon, where Jack ran 180+ with it on half track passes bacause the heat from th emotor was burning through his fuel lines!
Oh, yeah, I’d do that!
