Our Patented design is revolutionary in gaining throttle response, fuel economy and overall power in RC racing engines.

 Developed for 1/8 scale off road and on road racing to provide better mileage and power by utilizing a dual chamber design.

Similar to a double barrel carburetor in a car when the throttle is open only a 1/4 of the way it is only using a small side of venturi which creates more turbulence and intake charge velocity. But when you need all the power its is there, wide open throttle uses the entire venturi and both chambers so no loss of power.
 
Adds off the line acceleration, overall power and fuel economy. But is tunable to fit any of your needs.
FIts all .21 to .32 sized RC car engine carburetors
