MAHLE Introduces PowerPak Piston Kit For Wissota Concept Engines

New from MAHLE – the PowerPak Piston Kit for Wissota SBC and SBF concept engines. These pistons feature dual coatings and precision ring grooves for maximum sealing and power. See more details below.

Official Release:

MAHLE Motorsport now offers a PowerPak Piston Kit for Wissota concept engines for both small block Chevy and small block Ford. Featuring MAHLE Motorsport’s lightweight yet strong, low drag slipper skirt forging, dual coatings and precision ring grooves for maximum sealing and power, this new PowerPak is approved for Wissota Auto Racing and Wissota Late Models known for 347 – 360 cubic inch engines generating 500+ HP.

The all forged pistons are precision machined to exacting tolerances on purpose built equipment manufactured by MAHLE specifically designed for piston production and feature precision ring grooves for maximum sealing and power. The top ring groove is hard anodized to protect against micro-welding insuring optimum ring seal over the life of the engine.

The pistons are dual coated with a phosphate dry lubricant to guard against galling in the pin bores and to add lubricity in the second and third ring grooves followed by a Grafal® anti-friction skirt coating to reduce drag, scuffing, friction and cylinder bore wear. This proprietary skirt coating has a cushioning property that greatly reduces wear for both the piston and the bore as well as a substantial reduction in noise. Included in the kit are 1.5. 1.5, 3.0mm ductile iron moly rings.

Features:

  • Low drag slipper skirt forging
  • Dual coatings and precision ring grooves
  • Maximum sealing and power
