Polaris AXYS 800 - Billet Head Kit (2018)
-
Easy bolt-on power for your 2018 AXYS 800! This head has twice the cooling capacity to keep your motor running cooler to maintain horsepower by staying below the 120-degree timing curve.
- BMP Billet Head Kit for 2018 AXYS 800 HO Motors
- Low altitude kits gain 4-5 mid range and peak horsepower
- High altitude kits gain 8-9 HP in the mid range, and 7-8 peak
- No jetting or EFI changes required when just running the head
- Head can also be run with our durability kit and no fuel changes (10-11 HP combo!)
- Fuel controller is required when running in combination with our pipe
- We recommend running BR9ES NGK plugs
- High altitude PN: 04-315-H
- Low altitude PN: 04-315-L
We offer two different dome configurations:
800-37.5 is a 12.5:1 compression ratio that works great in the 6000-9000 ft range and bolts on 7-8 HP in the mid-range and 5-6 HP peak.
800-41 is our lower 11.8:1 compression version for sea level to 6000 ft and gains 4-5 HP. The stock 12.1-12.2:1 compression ratio makes the motor's detonation sensor kick on very easily and won’t allow you to lean out the motor for extra power. By bolting on this version it allows you to lean out your machine with a fuel controller and pick up 5-6 safe horsepower. Some people have purchased this version simply to make it run cooler and less likely to set off the detonation sensor and put the sled in limp mode. This dome-design is different than others with a unique wider squish band and radius giving you great power and better reliability.
This head does not require a fuel controller when run by itself or with our durability kit but you must run in ethanol mode. If you run this head with our performance pipe, you will need a fuel controller.
