That is pretty damn sick! Is 23psi pretty typical for those motors?

23PSI is not unheard of at all.

Thanks Robert, these cars sound better by the minute. I would rather have one of these over the 5th gen or challenger all day long

6000.00 is too cheap for this kind of power!

I wonder how much the stock exhaust is holding it back.

A blower system for a vette runs about $6k unistalled, correct?

A stock LSX probably wouldn't have lasted one pull @ 23psi.

True. But you do need over $6k in mods. It's all relative.
