The Importance of Compression Ratios and how to Measure Them » DR-1103-PISTON-01

Funny Car teams replace the pistons after every race pass and every second qualifying pass. Pro Stock teams replace them after every 40 passes approximately, and weekend warriors replace them every 12 to 18 months, sooner if their engines are nitrous-assisted. Frequently, piston changes lead to compression rate changes.
