The new MXR v2 .21 Nitro Engines made by O.S. is now in stock. This is the same engine that Dakotah Phend has used for the last year except with red anodizing instead of orange. Includes the Airmax High Flow air filter for maximum engine power.

 

The MXR v2 Team Edition is hand assembled and pre-broken in by the Ultimate Racing Factory using a dyno so that every engines is exactly the same and fully broken in. Although the engines does not need any further break in, they recommend idling 1 tank to lubricate and seat all the parts, and running 2 tanks on the track with a rich top end carburetor setting before putting a full race tune on the engine to be safe.

 

The 2141 pipe is the Ultimate Racing Smooth pipe for a linear power band and recommended for small tracks. The 2142 pipe is the Power pipe for maximum bottom and top end power. Both pipes are super strong and provide the best fuel mileage.
