STAR Machine specializes in crankcase vacuum technology for the motorsports industry. Using sound engineering principals combined with creative concepts and modern manufacturing techniques, STAR Machine is dedicated to providing only the finest quality vacuum pumps and components. Each pump is dyno tested and must meet or exceed the free flow and peak vacuum levels STAR Machine has published in our Performance Graph before it is shipped. Star Machine factually represents our pumps performance, size and weight. We don't use vague terms such as "lighter than" or "more volume than." We provide you with the exact weight, dimensions and performance of our products. The availability of 3D Model downloads of our vacuum pumps is an industry first.
