Build an LS1 around a turbocharged application, then let's do a comparison. Still sounds like a fun car though.
My Turboed LS1 put out right at 600.... Thats 1.729. I have dyno sheets to backup. This is also a stock car from the factory. You have to build a 730 HP LS1 but then you could buy a new car with what it would cost. Been there, done that.
