Frequently Asked Questions

What compression ratio is this piston designed for?

This piston is designed for 10.5:1 compression ratio and is best suited for stock or mild builds running on pump fuel.

Why hypereutectic instead of forged?

Hypereutectic alloy offers superior thermal properties and low expansion ideal for air-cooled engines, providing quieter operation and tighter ring seal than other cast designs.

Will this piston work in my 88 cubic inch engine?

No — this piston is for engines bored to 95 cubic inches. Do not use in stock 88ci displacement.

Can I run boost or nitrous with this piston?

No — hypereutectic pistons are not recommended for forced induction or nitrous. Use forged pistons for boosted applications.
