Zodiac International - Star Racing Camshafts

Anyone who has heard of the brand name Star Racing knows that it is synonym for horsepower.
Star Racing founder George Bryce is one of the "Gs" in G-Squared Motorsports, the world championship winning cooperation between Star Racing and S&S Cycle Inc.
They have taken the most power out of any gas burning Harley-Davidson and reached 200 mph in just 6 seconds. "Now all of George's knowledge about gaining usable horsepower is available in this 'boundary pushing' range of street and race Star Racing cams.
"In addition to boosting horsepower and torque these cams let Twin Cam and Milwaukee Eight engines sound like a Harley should."
