Kinda sad to see the mention of Cosworth in the next-to-last paragraph. I really wish they could still be in The Game.Ted68 wrote:A brief article on the new engine.

This seems to comingle acoustical and gas flow concepts. Acoustical pulses are excited by the pressure wave essentially at the exhaust valve opening. However, the pulse wavelength is a function of the resonant length/diameter of the pipe and the open/close- end configuration of the pipe. The wavelength determines the spacing of the pulses in the pipe and, accordingly, the position of the pulse relative to the valve at any given time.rscsr wrote:[That's a rather good idea, but with one caveat. The difference in the pipe lenght is rpm dependent. I estimated with a speed of sound of 700m/s a difference in pipe length of 0,292m (at 12000rpm) and 0,343m (at 10000rpm).
But after thinking about it, I don't think they would care much about the not equidistant pressure pulses, as a pressure pulse is at 10000rpm about 2m long (if we assume exhaust valve opening time of 180° crankshaft angle). So you wouldn't need to worry about that the overlap of pressure spikes (or they would make 2m long exhaust pipes to the turbo, which I don't think is very likely).
Not very likely in my view. The fuel flow limit is a strategic issue and has been defended by nail and tooth over the last five years. Todt has the upper hand now because F1 as a whole frowns on last minute rule changes. The manufacturers as one man would put up a riot if the fundamental data of the engine were to change in the very last minute. So you can forget about that thing to happen.rjsa wrote:...a little messing with the SECU can bring up the fuel flow limit and may be even the revs for some fine tunning of the show.
Is this official already? Not only Domenicali is worried about the test situation (absolutely justified imo), but also Rob White recently expressed his concerns about the possible scenario that Honda could do an unrestricted test season in 2014 in contrary to the regulation-bound current manufacturers and could be the winner takes it all in 2015. Given the complexity of the new power trains the situation is unsustainable. Reffering to Joe´s brilliant article you mentioned above, it´s obviously all about power and money. One should suspect that Ecclestone and Walker are trying the other way round: They can´t stop the turbos anymore, so they want to disavow them by provoking technical difficulties in the first races of 2014. No additional test plus additionally increasing the rev limit (because of the "sound" ) could lead to some engine failures, doesn´t it? But it´s not even worth discussing. We won´t have the aerodynamic-focussed F1 with frozen engines next year any more, in fact the hybrid powertrain will call the tune from now on. And if something gets more important it should be considered more.WhiteBlue wrote:http://www.f1today.net/en/news/engine-m ... 14--report
Report about an additional engine test day probably in January 2014 in the Near East.

The Japanese manufacturer will return to the Circus to promote the Lexus brand. The engine was designed and will be built in the factory in Cologne and will therefore not be made in Japan. "
Asked about which team could use Toyota/Lexus powerplants
"Currently the more interesting team without a contract seems be Williams (who has already had the Japanese customer engines in 2007 and 2008, ed), but it would not surprise me even a concern for McLaren "
