PWN carburetor features an innovative half-moon slider design that allows the flow rate of the main nozzle to better fit the large bore venturi. Equipped with two units, they function at high speed or low speed accordingly to achieve the vehicle a big boost in power, throttle response and overall engine performance. The special features of PWN carburetors are its short overall length for improved top end power and a redesigned slide for improved engine response. Performance throughout the entire power band is excellent. Definitely one of the best options for tuning and racing projects.
