These rules are the rules that Hanging Rock Speedway used with their stock Predator ( out of the Box ) class. The only changes to the rules are so they are easier to read and adaptable to Patriot Speedway
Our intentions are to continue the class at Patriot Speedway in it's original form. We will run this class with EL tires only.
Age 15 years and up : 375 lbs class....
Open Clutch and axle gear rule ....(no skip tooth allowed)
RPM rule on the governor.
To get to the rpm you want, adjust the throttle stop screw to come in before the required rpm rule. You may remove the spring on that screw and replace it with a nut so that you can keep it locked into the desired rpm.
RPM will be checked with a tach of tracks choosing
5500 RPM max.
An engine that is over the rpm mark will be disqualified. Arguing with us over what’s legal and what’s not will not be tolerated. The governors must kick in when checked.
No claim in this class, Protest only. Must finish in the money or capable of moving into the money in order to protest. Must finish behind the person you are wanting to protest. No protesting behind you. (See protest rules under the note section)
1) The engine must be OEM out of the box…hemi heads are allowed in this class
