Your profile says you are a student. From what you've demonstrated here, my guess is that you're not a very good one.:? I'm going to try one last time to teach you something about Superchargers and how to use them correctly and efficiently!

Start by reading this entire article (most of the references in it are from BDS "Blower Drive Systems" if you know what a blower is you should know this is one of the top blower manufaturers in the world) http://www.digitalnoesis.com/trucktech/boost.shtml

You wil notice that the optimum FINAL compression ratio for blower efficientcy is around 12.4:1 for 91 Octane fuel..... That's the FINAL compression AFTER boost!!! That means that if you start with an engine that is already close to that compression ratio, your blower is not going to provide the optimal compession ratio and you're defeating the purpose of the blower and you will not get the performance you're looking for unless you run a fuel like AVGAS (115/145 octane) or maybe 106 octane racing fuel... In any case not very practicle for a street application!!!

With that said and trusting that you have read the article..... If you still want to make the uninformed statements regarding blowers and compression that you've been making, then you truly are not the sharpest knife in the drawer.

END of lesson......
