    Hope everyone’s doing well. Just had a quick question. So I purchased a 2021 Slingshot S tech manual. I went ahead and did the Polaris Tune that gives it the same HP as the R edition. Now…onto a little more power. So I was told that either the 2020 or 2021 was when they did the new engine. So...
  2. For Sale
    $22,500 OBO or trade. I have over $45,000 in it but I understand the options do not add much to the sale value. Supercharged and VERY fast when you want! The picture does not show all of the options as it was taken in late 2017. She is in excellent condition and needs a new home since with my...

    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...
