Simply not correct. Torque is multiplied through gearing, horsepower is not. |
The 1M puts over 100 more lb-ft to the wheels than the E9X on the average a wheels dyno, ie dynojet. ~360 lb-ft for the 1M plays against around 255, which is where my comment came from.
Taking gearing into account, as you suggest, the 1M 1st (4.11) gear and final drive (3.154) give torque multiplication resulting in a peak of nearly 4700 lb-ft to the rear wheels in 1st gear, while the M3's engine and gearing results in 3900 lbs-ft, or 800 lb less.
In second gear the 1M is putting a peak of 2600 lb-ft of torque to the wheels while the M3 has 2300, 300 less. Thus in lower gears where you're traction limited the 1M is trying to put
hundreds of lb-ft more torque to the ground than the E9X M3, which is much of where it gets its tail happy character.
Does that address your concern?
