Just wanted to see what your opinion would be on Lotus' views.
Why is the blown floor seen as a performance improvement.
I never said it wasn't a performance enhancement, and given that it almost HAS to have negative characteristics, I can't think of a single reason anyone would use it if it didn't make them faster.
The things that we as outsiders know are limited, but we do know that every exhaust used today is less effective than what was used last year. If this were not so then everyone involved in designing every F1 car would have to have been too stupid to see this great advantage. That would include the Holy Newey.
We can guess that the negative impacts of todays exhausts are not as great as last years. I can't think of any way to estimate how much less.
We can assume that the ratio of performance gain to negative impact is not as favorable as last years. If it were better they'd have been using todays exhausts then.
So, if the outright performance is lower, the negative impact is lower, and the ratio between them is lower, how could it be possible for say Lotus to get a bigger gain out of it than was possible last year?
I'd say wishful thinking most likely, though it is possible their car is so underdeveloped that massive time is there to be gained. They do have some clever people on board and we have seen back marker teams make sudden big gains in the past.
What I've said all along aplied only to top teams. You can't assume the McClaren or Mercedes is plain underdeveloped. That's both silly and rude to the many top level engineers involved. You CAN say it about Lotus, because while they have some clever people they don't have enough of them, and they certainly don't have enough money.
I still say whatever is wrong with the Ferrari is a glitch, something gone wrong. Since the only thing that's changed massively in recent weeks is the tires, I'd bet something about that change really doesn't get along with their car. Pirelli is unlikely to change their tires back, so it's going to be up to Ferrari to change their car. This is fundamentally different from "gaining performance", this is fixing a problem and REgaining peformance.
I still hold that is exactly what happened with McClaren. Whenever Williams gets its act together, same issue, though in their case it will be reliability performance regained.
And I'm still saying you can't claim these systems, any of them, are worth a second, or even 1/2 a second, in isolation. For one thing, any diffusers performance is going to be directly impacted by the rear suspension and rear aero around the diffuser. Again, I'd ask you to look up those bouncing Marches to get an idea of how badly wrong it's possible to get things.
Also, all of these systems impact the rear only, and given a mandatory C of G, there exists an ideal Center of Pressure, which unless you can balance with more front DF you've just moved rearward. This means that whatever your exhaust blowing is doing, it can't ever be as important as your front wing.
