Our line of Super Stock pistons for Banshees work to add power by simulating that the exhaust ports in your stock cylinder are timed differently which really means the same as hand ported with out the hassle.
The Super Stock is notched on the dome next to the exhaust port to theoretically raise the port, which will raise the rpm range of the engine and develop more mid to top end power.
Re-jetting is required since you will need more gas & fuel for all the extra Horsepower and Torque. Use our JK350 jet kit for open air boxes for the most power gain!
