I didn't expect to be writing this comment on this article hah, but apparently there is such a thing called a surge tank for storing boost pressure to mostly eliminate turbo lag:
It's such an obvious idea that I'm kind of shocked it took them until 2003 to do it. Surely someone thought of this in like the 60s.
I would probably do it differently with a separate supercharger to intermittently maintain another 1-2+ bar of boost to make the tank less than half as large, but that would add complexity, and what do I know.
Afaik the general solutions to turbo lag are 1) a smaller turbo, 2) two turbos in stages, one spools earlier, the other later, 3) a transmission/differential/tune tailored to be in boost near-constantly during acceleration (something like a 10-speed cvt designed to keep you in high revs when accelerating in sport mode; not only keeps you in boost but is the ideal power band for these non-diesel boosted sports cars)
CVTs shouldn't even have a concept of "speeds". I absolutely hate how manufacturers will build cars with CVTs and then make them only go into discrete gear ratios. It completely destroys the entire reason for having a CVT.
I understand that they do it because people don't like how CVTs sound/feel, but maybe they should all have 3 modes:
1. Eco - optimizes gear ratio for maximum effeciency
2. Performance - optimizes for maximum power
3. Sport - pretends to be a normal transmission for a better "feel".
