In an effort to introduce natural gas into racing, Patrick Racing has selected Katech Engineering to build its engine for the 2013 American Le Mans Series (ALMS) Prototype Challenge Class. Over the next month, the companies will work to convert the existing 400+ hp (298+ kW) Chevy engines to natural gas, followed by static and dynamic dyno testing. “There are some inherent benefits to natural gas as a fuel,” said Stephen Chue, President and Technical Director of Katech. “Apart from its domestic abundance, appealing cost, and sustainability, it’s a strong replacement for gasoline or ethanol. Natural gas comes out of the ground at approximately 130 octane, making more power feasible when managed properly.” The use of natural gas in racing engines will also help the ALMS continue as a leader in green racing and keep it at the forefront of automotive technology.
