Industrial Injection Dyno DaysClick here for Pictures from the Industrial Injection Dyno Days event on August 14th, 2010. Congratulations to Steel on his 731 Horsepower Dyno run and to Gene Tourangeau on his 868 Horsepower Dyno run! Both were in the top 10 overall! Steel's truck is a 2006 F-350, for which we built a Commonrail motor from the ground up along with a custom set of GOS Twin Turbos! For more information on Steel's truck, other GOS Cummins conversions, or to find out more about a conversion for your own vehicle, check out the GOS Rides section of this website!
