Over the past couple years DPR has been developing what we feel is the optimal set up for the Zenoah.
We are proud to introduce our newest developement, the Pro version of our WildChild engine line up.
All new piston design has been added for less cylinder wall drag, optimal transfer port flow and improved port timing.
We are offering an in house, highly modified CY piston, We have found that the CY piston offers supperiour casting in the wrist pin area for better flow through the transfer ports and a more accurate and consistent placement for the wrist pin. We also relieve the top portion of the piston to prevent cold siezures as well as relieving the wrist pin area to prevent siezure and limit the amount of cylinder wall drag.
We have also found the CY intake manifold to provide a better sealing surface between the manifold and cylinder. The intake manifold is port matched to each cylinder for optimal flow.
These new modifications are only available in our PRO line of engines.
