Has anyone tried the Rotrex Supercharger on a Rotary Engine - particularly a convertible?

 

never heard of it.

link? info?

 

I had never heard of it before either, but a quick search uncovered this web site.

Of course when it comes to superchargers, people generally go with a nelson/paxton unit. what are you looking for exactly?

 

VW mod?

 

well not only VW's but it's a very short list. Here are the supported kit list:

Audi, BMW, and VW

 

That's a lot of Euros! Looks like it adds gobs of hp though. I'm assuming it's an entire kit with pulleys, etc. I'm assuming you'd try to fit it to an NA 13b—aside from fuel and intercooling—I'm sure you could get an adapter made for you at a local shop. Pulleys are probably not gonna be the correct ratios though. Unfortunately it's a steep price to "experiment" with that particular supercharger. I have yet to see anyone pull one off, say, a Millenium S and try to adpapt that. Makes one wonder if Mazda ever adapted a supercharger to the 7…
