Hyper-Valve
How the Hypervalve works!

Generally, internal combustion engines are delivered fuel from a fuel cell in a variety of methods. The method used in most RC applications is to create a pressure in the fuel cell from the exhaust in order to push the fuel from the fuel outlet of the fuel cell to the engine. The problem with this method is, as the RPM of the engine changes so does the exhaust pressure of the engine. The fluctuating exhaust pressure changes the pressure in the fuel cell due to the unrestricted channel used to connect the exhaust to the fuel cell. This major pressure fluctuation creates a non-efficient flow of fuel to the carburetor as well as a lag in the engine response due to time required to pressurize the fuel cell to push to the engine. The engine response is the time difference between when the throttle body is advanced until the time the engine changes revolutions per minute as well as the time duration to perform the change. The delay in engine response is partly due to the time required for the pressure to build up in the fuel cell in order to supply the engine with the additional fuel from the fuel cell required to increase its revolutions per minute. To increase efficiency, output power and improve throttle response the fuel cell needs to hold a higher and more constant pressure such that fuel can be delivered to the engine as the throttle is advanced. The Hyper-Valve System is a fuel boosting mechanism that holds the fuel cell at a higher pressure for an extended period of time while engine RPM fluctuates due to normal use of the RC vehicle. The unit itself is small and lightweight while very simple to install. Hypervalve Info
