OUR PROCESS

When your engine arrives at our facility, it undergoes a detailed inspection & disassembly process. Our dedicated Clean Room is where the cases are meticulously cleaned using a proprietary process that removes all oxidation, dirt and grease, ensuring when you receive an EVP built engine, not only is it new on the inside, but it looks new on the outside.

Our specialized technicians expertly assemble, setup, calibrate and test your new engine, set to your customized specifications.

Prior to shipping, every engine is filled with oil and we let it sit for 24 hours to ensure there are no leaks. Once the final inspection is complete, the oil is drained and the engine is packed in a wooden crate to minimize the risk of shipping damage.

BRINGING POLARIS POWER TO THE NEXT LEVEL.

Here is the first of many new big horsepower XP Turbo products - brought to you by Evolution Powersports.
The OEM cylinders are a thin wall cast material and do not provide an ideal sealing surface for the head gasket. With EVP XR Series Billet Cylinders, we are able to provide a stable sealing surface to go with the BC/ARP CA625 Head Studs.
The integrated iron liners further provide the needed strength for the increased cylinder pressure of the big power / high boost applications. The closed deck design still provides ample cooling around the top of the cylinder while providing additional strength on the deck surface.
Our NEW Billet Cylinders coupled with the Brian Crower XPT/Pro XP Engine Components are ready to take Polaris Power to the Next Level. The EVP Billet Cylinders are 100% direct replacement – no block machining is necessary.
