This should please Mateschitz no end, don't you think WB?

I don't understand your comment. How is Honda connected to Mateschitz? The only potential connection I see is Honda could have taken over the PURE project that could have been started by Mateschitz some time ago. But that is a very long string.

The turbo is only one of five sub assemblies that are limited in 2014. You can only use five units of each type of sub assembly. And I see some risks for the turbo as well. The temperatures will be pretty high on those units.

In most cases people will locate their turbos in the central rear part of the engine and therefore near the electronics and the temperatures can reach a thousand degrees and that won’t be an easy matter to deal with. Managing temperatures will be one of the main areas we will have to work on.

At least one manufacturer had severe problems with the turbochargers, as they exploded in series during testing with the power of a pistol shot, so they even started to think about some "safety box". But they managed it and it is great now. But the temperature problem remains...

Besides, there is already a japanese connection to Red Bull, why I don't think he will mind the Honda-presence.

The engine homologation changed this. There were much more manufacturers leaving than arriving, and I don't see this imporving outside the rule change window - even with Honda arriving one year late I'd bet they will be the las ones to hop in.

If you read what i said then read what you said, you see we both said the same thing except i added that after Quali they cant change the maps they have, which is what i was poiting out with the computer hookup. As in after Quali they have what they have for the race, and it can be 10000 maps or 10.

I see what you meant. But don't see the problem. This just proves that they CAN have a qualifying specific map if they need it. Which is what we were discussing ...

yes they can have as many engine maps they like, the limit on the trottle pedal to torque map
I would guess it is to prevent bypassing the limits on how that map can look (passive TC?)

Outstanding thread. I am drinking every word and learning every page. Thanks for your contributions, (especially WB and expensive) they are noticed and appreciated. =D>

Is there any manufacturer that you all know of who is leading this new 2014 engine front as far as overall power is concerned? I read here that it seems Ferrari may have some issues, but nothing major, but little from the other guys--Merc, Renault, etc...

Secondly, since Honda is joining the fray in 2015, does this mean that they basically can get an older car from Macca and run it all they want on their own testing schedule/tracks for all of 2014 since they are not contractually bound in 2014 to follow any rule set? If so, does this not present a H U G E advantage for them in 2015?

The specification of he power train is very narrow and some crucial pieces like injection systems and software are going to be controlled by the FiA. It makes me think that performance wise we will see relatively small differences. But there is also reliability which will play a role at least in the first year. My money for the best engine would be on Merc because they would have the deepest pockets and most resources of the three.

Honda can test their engine in LMP1 or in an F1 car for next year, but that is not going to be much of an advantage. The other guys will get a steady stream of competition data to improve their design and all four have limited time under the freeze scheme to optimize things. I don't believe it will be an advantage for Honda.

I too would love to know what the problem was? I did notice that Renault had turbine wheel burst bolts on the turbine.



The turbine shafts will probably have to be larger then normal to run closer to "Shaft Critical Speed" that these turbos will be running at to maintain the high load for efficiency the MGUH will require.
