x'ed,

I read on the Thomas Knight site that it was simply an extended shaft on a replacement alternator that allowed the existing belt to drive this 'supercharger'. I do not understand how you figure you would need more batteries for this type of installation.

On his 'electrical supercharger' system, then yes you would need the additional batteries to allow for the electrical drain during operation and a second alternator to recharge those extra batteries. The electrical supercharger system that they have utilizes several high RPM starter motors to turn the impeller(s) of the supercharger and are a serious amperage draw.

I to enjoy your posts x'ed, I am enjoying them now... we all need to keep everyone on track and try to avoid confusion on this stuff so the correct information is presented so it can be evaluated for the best benefit of the forum users.

Cheers!
