Besides, why worry about beheamoths like LS1's - it's when you get beaten by a little white Colt that you need to address the concerns:

Anyway, back on-topic - to beat a stock LS1 we need to be pushing 255hp at the flywheel which would bring us on par in the power:weight stakes, although weight reduction is where our cars will really come into their own.
