1340 cc EVOLUTION - 8.5:1 COMP. RATIO
The J&J 390 Hypereutectic alloy makes it possible to build a light weight piston that creates MORE POWER, Runs Quieter, uses Less Fuel and Lasts longer than other pistons made today. You can now forget about running loose and noisy oil burning pistons because of the low-heat transfer rate of the alloy this helps keeps the skirts cooler and piston expansion is kept to a minimum. Hypereutectic pistons can be installed tighter than other performance pistons thus a close fitting piston rocks LESS, supports the ring better, and seals the engine for maximum power. The combination of a low heat transfer alloy and high compression ring placement INCREASES power and fuel economy. The high ring placement alone reduces detonation and increases the top ring temperature.
Our J&J pistons are the finest Hypereutectic pistons produced today.
