True, my diesel truck has around 1200ft/lb of torque and 625hp. I only make 43psi of boost. I think the engine is 16-17:1 compression ratio. On the 5.9 Cummins the torque is real close to double the HP. Sometimes more. Playing in the diesel world, turbo drive pressure and timing will also effect cylinder pressure.
