AERO OPTIMIZED INTERNAL SURFACING

The Rad Valve is the ONLY air intake system available with aerodynamic internal surfacing. Internal precision surfacing treatment eliminates all hard edges that interrupt with the proper delivery of air and fuel. Attention to the specific air and fuel requirements of each machine's unique engine pressures gives the RC2 Series Rad Valve the ability to reach consistent peak horsepower gains, optimizing the power profile to produce instant, explosive movements of air. The Result: Unparalleled performance.

X-CROSS DUAL CARBON WEAVE

The Rad Valve's Multi-Staged reed petal stacks feature the absolute highest quality aerospace grade carbon material interwoven into specific tension combinations that maximize power delivery and peak horsepower. Boyesen engineers specifically tune the carbon matrix tension using a proprietary weave formula and special layup techniques that optimize each Rad Valve Reed to work in unision with the engine unique intake pressure pulses for each make/model/year machine.

MS PLUS FLOW OPTIMIZATION

Boyesen's race-proven MS PLUS Optimization uses multi-staged reed petals to distribute the engine?s pulse forces over more surface area. By using a multiple reed petal stack, it is possible to acheive peak horsepower and durability. The patented multi-stage design incorporates a specially shaped top reed petal and a ported bottom reed petal. The top petal is lightweight and resilient for crisp throttle response at partial throttle or low RPM. The stiffer, bottom petal is ported to provide maximum flow and horsepower at higher RPM.
