The supercharger probably wont be going on this year, so I dont have a problem with swapping out the pistons and cam. They're fairly inexpensive. But, im not really sure what kind of supercharger I want yet. I like the fact that centrifugals dont spool up until you really get on it so they are better on gas, but who cares about gas in a just for fun car? It would also be concealed though. Nothing shouts power like a damn roots blower popping through the hood. Roots style blowers seem to be cheaper. I need to do more research. If I could pick up a used blower for a $1000 I would do it. I started off thinking about 500hp, now im changing my mind again. It all comes down to the hp-dollar ratio.
