New FRP/Wiseco E85 and Race Gas Piston
FRP Engineering is proud to announce our all new line of extreme performance Race Gas and E85 Pistons for Audi - AAN and 3B inline five cylinder engines. They are the result of a considerable engineering partnership with Wiseco Piston and have been proven in the FRP Land Speed Record holding S4 sedan.
These are the first "flow and compression optimized" racing pistons for these engines utilizing true 3D dome milling and Aero Humps that interface with the intake valves during overlap to enhance cylinder filling and increase scavenging of burned exhaust gasses.
