    Great News! Our supply bottleneck with Rotrex has been taken care of and supercharger kits are in stock now! This is the ultra reliable kit we have been selling now for a couple years that has everything needed to bolt a Rotrex supercharger to the Slingshot engine. If you are on the fence...

    I have a new 2017 SS base, which I am starting to customize. With all the kits out there now, I thought there would be more talk in this area here. I could not find any threads on this discussion so figured I'd start a poll and get your opinions on what you think is better.

    We have been super busy, but finally had time to test some custom cams we had made for us and the results were pretty awesome. For those that are not super familiar with the cams on the LE5/LE9, the cams have integrated passages in the front that allow oil to flow up to and back from the cam...

We had a great time talking with everyone and answering lots of questions, hope to see everyone there next year again!

    I just wanted to write a quote post about the installation and information about the actual kit itself. I called Dave at DDM Works - they did not have any supercharger units in stock.

    We had a great time here on Friday, a bunch of folks showed up for a dyno day and also a Rotrex install. It was really nice to meet @Sling Cat and have the chance to install a Rotrex supercharger on his Slingshot. We thought it would be fun to time an install this time since we haven't timed any...

    We were very happy to get one of the early 2.5" Welter Performance dual exhaust setups to test with our DDMWorks supercharged Slingshots and we are pretty happy with the results. While driving the exhaust is still able to be heard, but since it exits behind the Slingshot now, it makes cruising...
