It takes pretty much the same amount of air to make 1000whp regardless of the motor, some engines are more efficient than others, but a 4G63 making 1000whp at 50psi is about the same amount of air as a 7 liter making 1000whp at 14psi. It's going to be around 100lb/min of air regardless of the boost level that it happens at.
