With 12 World and National Records and 9 Championships already under its belt in its debut year, the new Patent Pending - Pro Systems SV1 Series (SV- Single Venturi) line of carburetors is the most innovative, power producing and throttle responsive designs available in carburetion today. 


The SV Series line of carburetors are designed for maximum performance in all categories of operation.  The SV1 is designed for Street use applications, High end bracket racing, Class racing and Nitrous applications when maximum power output and all around clean crisp and predictable performance from a program is required. 


The SV1 is a bit more expensive than our 4150 and 4500 series carburetors, so weigh your needs before considering the purchase.  Our 4150 and 4500 series carburetors are we feel, the best "bang for the buck" value in the performance carburetor world.
