I have contacted the company that advertises them several times, both by e-mail and over the phone. While I do not believe the superchargers will work on our two-cycle engines (I don't want to get into that just yet; it's a whole different topic than what I am going to get into), I think they might have a chance on a four-cycle. I have been working on getting the O.S. FS26C to work in an NTC3 and would like to play with a supercharger set-up on one. Despite multiple phone conversations, and assurances that they had supercharged four-stroke airplane engines, I have had no luck in getting them to call me back or return my e-mails. Every time I call them I feel like I'm Bill Murray in "Groundhogs' Day". I start over every time explaining what I want. They assure me it will be no problem and that an "engineer" will contact me. I have repeated this process several times with them. So maybe a bigger question than whether the supercharger will work is whether you can actually get them to build one for you. Good luck.
