Without question, the highest performance pistons available for high output, high rpm 4-stroke engines. Available in both stock and big bore. Pump gas and race gas compression ratios.
The 12.25:1 compression Venom pistons will out perform ALL other piston brands up to 13:1 compression, yet still be perfectly safe and reliable using pump gas.
The Venom 14:1 compression pistons are the highest performing pistons, and should be used with race/ high octane fuels of 105 or greater octane rating.
Beyond the static compression rating of a piston, there are many factors that influence the longevity and performance of a piston design.
