Star Machine

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.

With four distinctly different mechanical pumps and an electric pump, STAR Machine has an ideal vacuum solution for any racing application. No longer do you have to settle for a compromise when choosing a vacuum pump. Size for size and pound for pound, no other vacuum pumps can match the performance, efficiency and reliability of STAR Machine pumps.

At STAR Machine, vacuum pumps are not just another page in a sea of products in a catalogue. We specialize in vacuum pumps; it's all we do. Extensive research and development, on and off track testing and feedback from past and current world champion racers and engine builders has led to what STAR Machine has to offer. Our pumps incorporate precision coating processes to reduce wear and friction. Port locations with respect to vane timing have been optimized. We are the first racing vacuum pump manufacturer to utilize a one-piece aluminum shaft/rotor combination. This design eliminates fastener failure, key/keyway wear and dissimilar thermal expansion rates which allows reduced clearances for greater efficiency. We use precision sealed bearings with outboard locations for isolation from extreme heat, contamination and ease of service. Strategic profiling results in more surface area for better heat dissipation. Mating surfaces are o'ringed to insure sealing. The proprietary vane material is superior to others currently used in racing vacuum pumps. These features all contribute to pumps which operate with less friction, less heat and less wear. STAR Machine pumps are typically run at slower speeds than other pumps while maintaining better results.

Most of our pumps contain a provision for a built in vacuum regulator eliminating the need to cut holes and welding. A pump-mounted regulator also reduces additional oil from being scavenged from the crankcase when the vacuum exceeds the regulator set point because its location is outside the crankcase. This location also allows ambient air to flow directly into the pump, instead of only heated crankcase air, helping cool the pump thus reducing parasitic loss. All STAR Machine regulators are infinitely adjustable, there are no springs or shims to "fool" with. Simply loosen the jamb nut and turn the head to increase or decrease the vacuum set point. All our regulators have screened inlets to keep dirt out of our pumps and out of your engine. In addition to the pump mounted regulator STAR Machine also has traditional models, inline models that can be spliced into a hose at any location and models that mount directly onto other pumps containing -12 AN fittings. All internal parts are interchangeable.

Every company in the world tells you they have great service. The truth is that at one time or another we have all had our moments with someone we have spent our money with and wish we didn't. At STAR Machine we feel our service sets the standard that any business should be trying to achieve. Nothing we print here will convince you that our service is different than anyone else.

We encourage you to ask anyone with a STAR Machine vacuum pump about their experience with our company. We are very proud of the relationships we have forged within the racing community and cherish the privilege of our customers business.

We look at every pump application on an individual basis to ensure you get the correct pump for your application. Once the correct pump is determined we further fine-tune your application by selecting the proper pulley ratio to satisfy your needs. After all, would a specific pump and ratio that's ideal for a four cylinder engine that turns 11,000 RPM and trying to maintain 10 Hg. also be the ideal components for a 815 CI Pro Stock engine that turns 7600 RPM and trying to maintain 22 Hg.? You don't have to be a vacuum specialist to know the answer. The ideal pump for any application is the one that satisfies the requirements with the least parasitic loss.

Weather you're a professional engine builder who has been using vacuum technology for thirty years or a racer with no prior vacuum experience, our experience is at your disposal.
