Looking at dyno's and comparing power to weight ratio I believe the 28i that's running will out steam around 100mph were the 35i will have the legs.

Its like saying an 35i with tune and downpipes will be simular performance to an 35is (stock).

Enclosed is an Dyno of an 28i,35i & 35is

Also around the track, the 28i standard since is lighter by 100kg has simular times around the track.


What I have found for comparison reasons is comparing the 328i and 335i - like for like cars but different engines.

Motortrend Figure-8

328i 0:25.90
335i 0:25.70

I do not believe it will be quicker - just simular
How about air temperature
