If you have ever wondered if GZM has a crank driven motor mounted driver's side VP104 vacuum pump solution for LS motors with electric water pumps. The answer is yes. Here are pictures from two different customer setups that were installed this year. The two customers chose slightly different pump orientations using our standard UVPM102 mounting bracket but both look like solid installs. The latest install, the customer opted to go with a Gilmer belt setup.

Special thanks to the customers that have taken the time to document their installations and share the picture with us. We are going to work towards collecting pictures for more of our systems so that future customers have good reference material.

We offer three different crank mandrels for the setup based on which balancer / balancer bolt you have on your power plant. If you are interested in one of these systems give us a shout.

Several people already know but we wanted to make it official to all our GZ Motorsports Facebook followers. Kyle and Paula Hanrahan have purchased the GZ Motorsports operation and have relocated it to the Hanrahan Performance Products shop in Hopkinsville, KY. The business is now known as HP Vacuum Pump Systems LLC (DBA GZ Motorsports). Bill says he has officially retired but is still acting as a technical resource to us to help insure we can provide the same quality products and customer service that customers have come to expect from GZ Motorsports. We have updated the business address and email address on the GZ Motorsports page, and we are working with an outside source to get the information update on the GZ Motorsports website. The business phone number has not changed. Please let us know if you have any questions.
