I don't know about that. The turbo would have way more torque through its RPM range, unless it was grossly oversized with tons of subsequent lag. I've seen plenty of twin-turbo 302 'Stangs beat big-block Camaros with about the same power.
My turbo Bug and Dad's aspirated Bug both make about the same power but mine is quicker and has higher trap speed. Dad is a better driver and our cars weigh about the same.
