ESP High Rev Piston for GP460 Reed Engine

ESP High Rev Piston for GP460 Cylinder/Case reed motors

A great replacement piston from ESP for the GP460 engine that was converted to a Reed Valve Induction Engine, (cylinder reed or case reed induction). Now with the “High Rev” feature, (5.5 deg more open duration for the ex. port) for more mid range and top end power that runs great with ESP reed ported top end kits. It will work in any GP460 reed valve engine with a 12mm wide, centered, (middle of the intake port), added reed transfer port, (your width can vary, and will work fine.). Oil grooves and oil holes are added for longer piston skirt life on the intake side of the piston, (helpful for The GP460 and RC engine reed valve engines). Of course, the quality top notch too. Everything is from ESP and CNC machined/hand finished to perfection. You can reach Doug @ ESP by phone at 616-458-8103 if you have any questions.


Work done:

1) High Rev feature.
2) Half Moon intake skirt shape for cylinder reed pistons, (works perfectly fine on reed case builds too)
3) Reed port window, angle machined to aid flow for better cylinder filling.
4) Oil grooves and oil holes machined on the intake skirt for more reliability.
