Drag racing is a gas -- and when it comes to Roush's new Mustang racers, said gas is propane.
The pair of Mustangs, set to compete in the NMRA Ford Nationals series, are powered completely by propane. Roush sees the fuel as a "right here, right now" green alternative to gasoline that could be used to lessen our dependence on imported oil. The company has already launched propane-powered F-150, E-series, and Super Duty conversions, but it expects the Mustang racers to capture more of the public's attention.
In order to run the fuel, Roush has equipped the Mustangs with some modified motors. The 5.4-liter V-8 is a unit originally built for Ford's GT super car, but the engine has been stripped of its super charger, treated to more aggressive cam timing, an altered compression ratio of 12.5:1, and other modifications required to run the fuel.
The car shown here, built from a 2005 Mustang, will be the first example built and ultimately piloted by Donnie Bowles. Bowles' Mustang will be on display at this year's SEMA show, and will be tested later this month. The second Mustang, built for Susan Roush-McClenaghan (Jack Roush's daughter), will be based upon a 2010 Mustang, and will debut in February 2010
