All I know is that my buddy had same exact setup as I have with a tune and was at 310 rwhp. Even weighing 200 lbs. less I would be surprised this guy would run even or beat it. That's not very many bolt ons either

 

I go to scc too! lol

 

I raced a S197 about four months agao and the only mods all I had, were the flows, o/r h-pipe, and K&N cai. He beat me but it wasn't a slaugter. Also, my cams alone probally gives me just as much hp as all of your bolt ons.
