I can see using only the air-air intercooler on the straights or when there's a surplus of cooling capacity from the wind and switching to only the water-air one in tight corners with the added benefit of a quicker gas-response time. What do you guys think about this?

EDIT: suppose I misunderstood a few things. Only the works team runs the air-water intercooler?

I would rather think that there could be a bypass to the cooler for throttle reponse. But maybe this is not needed due to the MGUH. Also there could be some sort of PRV in the inlet tract.

What is this? Are you sure the spelling is correct? Search engine dont find anything!

“We are often asked the question of whether there is actually any technology transfer between race and road car engineering. The answer is resoundingly ‘yes’ – but it’s a more subtle process than bolting bits from one car onto another”, says Paddy Lowe, Executive Director (Technical) at MERCEDES AMG PETRONAS. “There are examples of direct transfer – for instance the NANOSLIDE technology used to coat cylinder bore surfaces. And then there is indirect transfer, where F1 serves as a research laboratory for developing new solutions and showing the world what is possible.”

Tribology (surfaces): The development of surfaces breaks down into two areas: surface characteristics and coatings. When it comes to coatings, engineers are looking at changing the material of the surface to improve the way in which it interacts with its environment. For example, an aluminium engine block has a poor tribological surface, so that surface is changed with a coating that has the desired properties. This is where NANOSLIDE is used by the new Mercedes F1 V6 Turbo engine because the friction between piston and bore liner is one of the single biggest frictions in the engine – and of paramount importance.Nanoslide was developed starting in the year 2000 by Daimler and is protected by more than 90 patent families and over 40 patents. Since 2006, this technology has been employed for over 200,000 engines so far. Initially starting with the AMG V8, the application scope was widened and Mercedes-Benz will roll out this technology even wider in the near future.

These are two different "technologies". Beryllium is an element with outstanding stiffness and low density. The supposed "nanoslide" is a coating for the bore.
