FYI,
The D-1X supercharger was designed for the newer generation of cars (2018 to current). But you can do a direct swap for a D-1SC because it fits the same bracket. But if you're not maxing out your current supercharger now just swapping or upgrading to a D-1X isn't going to do much and can even lose power based on pulleys used. If you want more power, spin your current blower faster with either a smaller blower pulley or a larger crank pulley.
On my turd, I maxed out my D-1 supercharger (Oil fed which by the way is better than the D-1SC because of the superior step-up ratio and higher impeller speed). I upgraded to the F-1A supercharger and made a lot less rwhp because I couldn't spin the blower fast enough with the custom pulleys I had........basically, nothing worked. Sold the F-1A and tried a D-1X and that was another disaster because I couldn't spin it fast enough or high enough (RPM). Finally, I bought the F-1D supercharger which has the F-series transmission which is better than the D-series transmission with a D-series impeller and I'm able to spin it fast enough with no belt slippage but no dyno numbers at the moment.
Again, switching the supercharger out will not gain much unless it's maxed out.
I hope this helps
