How did they get it to run on 87 octane with 11:1 compression? It has to have aluminum heads, did they cut out timing? There's no way you could run any kind of boost with a supercharger on that engine. Sounds really cool though! I say go for it if you have the $$$, but you may want to lower the compression to at least 9:1 or so if you want to add a supercharger.
