Talk about serious. This model has more wins than even we could imagine. If you’re a 4150 type of racer, what can we say, this is it! If it’s naturally aspirated or using light nitrous (nitrous shot of 350 hp or less) this design is the one. It has all the features you could ever ask for in a carburetor. Machined stepped boosters, a true race fuel curve (not a corporate design), and a custom multi-adjustable bleed configuration that allows this model almost infinite adjustability. This design flat out works on almost everything. It even sounds tough cruisin’ the streets.
(Dogleg booster shown, annular model available.)
