They managed to lift the power with 50% from there culminating in the M3CS engine and retain those characteristics 
If this was the limit for the 3l I6 with no compromises and to reach 500+ hp it was needed to decrease compression and increase shovel size (inertia/lag) that’s not worth it. Then the engine need more displacement or power should have remained on S55 level IMO.
And yes, an AT can hide much of the lag as it did back in the 80s when huge lag was rampant in FI engines. |
It's a bit concerning.
Are they trying to turn it into a GT car or something???
