The Revolution Design Ultra Backplate is engineered to maximize fuel efficiency and enhance engine performance for OS .21 off-road engines, including B2104, B2105, and their OEM versions. Manufactured from high-quality 7075-T6 aluminum and PTFE hard-coated for durability and reduced friction, this precision-designed upgrade extends runtime by up to 30 seconds per tank.
Optimized Fuel Flow for Maximum Efficiency
The advanced internal design of the Ultra Backplate optimizes fuel dynamics by reducing flow resistance and improving fuel scavenging. When the exhaust port opens, the generated low pressure assists in drawing fuel more effectively through the crankcase, ensuring a smoother power delivery and increased efficiency, particularly in the mid-to-high RPM range. At lower RPMs, the improved flow design maintains a more stable idle and smoother throttle response, contributing to an overall better engine feel and improved consistency.
The Revolution Design Ultra Backplate is a direct-fit upgrade for all OS .21 off-road engines, including B2104, B2105, RNX, and Samurai models, making it a must-have tuning part for racers looking to extend their runtime and optimize fuel efficiency without compromising power output.
