I'm just saying I've had both -- I drove 20k miles with the Dinan 3 upgrades and 4k miles in the M3 -- and from personal experience, the Dinan 3 feels much faster.
With that being said, the more time I spend in the M3, the better I am at driving it and the faster it feels. Perhaps when I reach some skill level in driving it, it will feel faster. However, that would mean the M3 is a very driver skill dependent car, whereas the Dinan 3 is a car anyone driving can make fast.
And just to clarify, I have an EE degree, not an ME degree, so the wheel torque explanation was somewhat lost on me without studying it for a while. You could be right about that, but that doesn't change seat of the pants perception.
I never go by what people feel, as that is very subjective. To calculate torque in a gear, you multiply engine torque X trans gear ratio X rear end ratio. The trans and rear end are torque multipliers.
