in a way yes.

My engine is a 1.6, not a 2.0. Additionally, I am way more concerned with quick spool and broad torque than with ultimate HP numbers. This is for an autox car, and for that I need power that comes on quick and is easily driveable with the car at the limit. A car with 200 peak HP and 175 ft-lbs from 2500 - 8500 RPM will be faster than one with 300 peak HP that has 100 ft-lbs at 4000 RPM and 300ft-lbs at 8000 RPM.
