So why don't you plot E92 vs F80 torque curves, and show me where E92 is better even allowing for a momentary lag in boost on F80. What you'll conclude is that you're choosing to ignore a heathy torque increase across the entire rev range due to a blink of an eye 'lag' period.
Your obvious misunderstanding of lag continues, lag is a DYNAMIC concept which has very little to nothing to do with a dyno gathered torque curve and almost for sure can not be "observed" in your M6 video. In addition, I care about an engines peak hp much more than it's torque curve. Yes a broad flat torque curve is desirable but so is a high redline a lack of drastically falling torque approaching redline.

We do not yet know the new engines displacement, but if you call 3.0-3.3 liters large, OK. The latter idea sounds great, go with a design to assuredly have more lag, which BMW, like many F1 teams, are going to great lengths to reduce or eliminate.

Wait, I thought journalists know nothing about cars. OK, as long as they help promote your position they can be quoted and have a valid point, but when they have a contrasting opinion they then "know nothing".

Ugh.
