Why Choose a Piper Billet Cam?
- Ultimate Material Integrity: Machined from solid steel billet to eliminate the porosity and "lobe-softness" often found in re-ground original castings.
- Optimised Power Delivery: Designed to transform the 'A' series torque curve, providing significant gains in mid-range punch or top-end power.
- Enhanced Valve Train Life: The superior surface finish and precise lobe geometry reduce friction on cam followers, a vital benefit for high-RPM A-series builds.
- Proven Racing Pedigree: Piper’s 'A' series profiles have been the backbone of winning Minis and Sprites on historic grids for decades
Installation Tip: To ensure maximum longevity, always install a new camshaft with a fresh set of high-quality cam followers. We recommend using a high-zinc (ZDDP) assembly lube and following a strict 20-minute break-in procedure at 2000-2500 RPM to correctly "mate" the cam and followers.
Key Point: Machined from brand-new steel billet for maximum reliability in high-stress competition engines.
