Roush CleanTech Starts Production Of Ford 7.3L Godzilla V8 Propane Fuel System

Sponsored

The new Ford 7.3L Godzilla V8 has proven to be a popular choice among Ford Super Duty buyers thus far, as well as an intriguing toy for tuners and racers. But this is an engine that was designed to provide economical and reliable power for both retail and commercial customers. Now, the latter have an alternative fuel option to choose from as well, as Roush CleanTech just announced that it has started production of its new Ford 7.3L Godzilla V8 propane fuel system.

The company’s propane autogas technology integrates Ford’s new 7.3L V8 engine in a variety of Class 3-7 chassis. The Gen 5 Ford 7.3L Godzilla V8 propane fuel system features a number of innovations, include stronger and lighter forged fuel rails and a support bracket that keeps the engine fuel distribution well organized.

The propane-powered engine is designed to meet current and future emissions requirements as well. Roush CleanTech’s Gen 5 is certified to California Air Resources Board’s optional low nitrogen oxide emissions standard of 0.05 grams per brake horsepower-hour (g/bhp-hr). The Gen 5 system also reduces greenhouse gas emissions, which helps optimize fuel efficiency, and it can operate on renewable propane, which further reduces emissions and carbon intensity values.

Propane has become a popular alternative fuel for commercial fleets in recent years, due to the domestic fuel’s reduced costs and lower emissions. Roush CleanTech is celebrating its 10-year anniversary, and over that time period it has sold more than 37,000 vehicles across the United States and Canada.

The company is also a Tier 1 supplier and Ford Qualified Vehicle Modifier manufacturer, which means that all of its propane autogas vehicles retain all of the expected Ford performance characteristics, such as horsepower, torque, and towing, while also maintaining the OEM factory warranty. Roush CleanTech’s latest Gen 5 propane fuel system is available to purchase now.

    It’s pretty much a given that this engine will be the new gasoline and propane option in the BLUEBIRD VISION school bus where the V10 was for many years.

    The compression ratio of the new gas 7.3 is 17 percent higher than the old tech 5.8 liter V10. The 6.8 had a weak 9 to one compression ratio which is lousy for propane because LPG has 104 octane. The higher compression ratio of the two 7.3 engines is 10.5 to one, meaning significantly better MPG on propane and also much faster acceleration. The other lower 350 HP 7.3 engine probably also has a lower CR, but i haven’t seen the specs of the CR. It will be used in the F650 and F750 versions, as it is designed to get better MPG than the higher horse version used in the F250 and F350’s. All cars and trucks use the Blackberry QNX system to control all the electronics on cars and trucks, even the Italian and Korean made cars as well as the Rolls Royce and German made cars. Expect at least 20 percent better MPG with the 7.3 on propane compared to the 6.8 liter V10.
