Classic Austin Mini Cooper 73.5mm , 1380 powermax piston 9cc dish - SINGLE
$179.95 Classic Austin Mini Cooper 73.5mm , 1380 powermax piston 9cc dish - SINGLE
Made in a hyper eutectic alloy with a high silicon content to provide tight cylinder clearances and quiet running characteristics, manufactured by a world class piston manufacturer to "MAR Motorsport specification" uses an optimised crown and dish (9cc) shape for improved swirl/burn. The A-series always gives better performance with a larger piston dish and smaller chamber volume. It also means that an otherwise standard 1275 cylinder head and engine block the bore size increase can be used initially where required as there is no big problems with compression ratio. These are totally different to the original Evolution piston stocked pre 2012.

Top ring is 1.15mm, Chrome face Second ring is also 1.15mm height Oil Rings are 4mm

When Omega quit making A-Series pistons, Mini Spares took it upon themselves to design and build a better Piston. Recruiting the AE Hepolite Group for their unquestionable and renowned design and manufacturing expertise, the goal was to produce the most robust piston possible given reasonable cost and weight limits. Applying current technological advances incorporating their very latest hi-spec AE109TF lightweight alloy and special double heat treatments, the result is an extremely durable piston that will withstand greater cylinder pressures at higher RPM than any other currently available.

Piston Fact File
Created: January 30, 2000
Over the years, there have probably been a dozen "stock" 1275 pistons. Currently, three different designs are available from AE/Hepolite as "stock" replacements. All have an 8.4cc dished top, but compression ratios are carried by changing pin height (Pin height is the distance from the top of the piston to the center of the wrist pin- see dimension "A" shown here).
