F1 » Honda lays out engine token plans ahead of Spa


Just a note about what Arai is being quoted as saying (changing the gear-train system) for less friction, something that sups-up power produced. The above as being quoted can mislead the less technical or the less conversant with technical matters to believe that Arai was talking about the transmission (gearbox/diff) gearing. What Arai was talking about was the gearing pertaining to the engine (timing gears and the two way planetary gearbox having a reduction ratio of 50k rpm too 15k rpm which is used between MGU-K and crankshaft). This tiny reduction planetary gearbox connection to the crankshaft was the first problem (structural) encountered by Renault at the very first test when the new PU’S were first introduced, it took Renault (as I predicted at the time) 20 weeks to fix, some on here Taipan included will remember/will know what am talking about.

F1 » Button and wife gassed during burglary in France


Racemaster: Foremost, just glad that no one was hurt. If they were in fact Anesthetized involuntarily, things could have ended far more dire than they did. Someone would have to know precisely what they were doing to fill an entire house with just the right amount (a lot I am assuming) of gas to only knock out the occupants! Then you have to ask where these serial robbers are getting the gas from in the first place! Sounds like this has been going on in that region for at least 5 years!
Following the subject after this "Button gassing news" experts has been quoted as saying that gassing a house through the air conditioning system is highly unlikely.

F1 » Honda: We didn’t imagine F1 comeback to be so hard


Wrong. BlackMike is spot on. Arai himself says a dyno is totally inadequate and performance and reliability of the PU can only be adequately assessed once it is in the car on a circuit. McLaren built a 'size 0' chassis that compromised PU design and there was clearly a lack of communication between the two companies on this. Seems Arai himself never said that "a dyno is totally inadequate" no engineer worth his salt will ever say that. The size "O" build you talking about (Ron speak) is not new, in fact it migrated to McLaren exactly from RBR. Both car design (tight packaging) did cause PU problems, but that does not absolve the PU manufacturers from their short comings. In the old days when FERRARI where doing the most testing on their own track, McLaren were the prime movers to have testing cut.

F1 » Ericsson: Sauber's 2016 plans convinced me to sign


tommytrojan1: No offence intended, but what exactly were his other options? it's not as if he had the chance to step into another drive. Nevertheless, I hope his optimism bears fruit next season at Sauber. It would be great to have as many cars at the sharp end as possible instead of just making up the numbers.
Logic tell me that anyone of the Sauber drivers had not one but another four chance of finding another seat in F1.

F1 » Honda: We didn’t imagine F1 comeback to be so hard


As to their (Honda) ICE power output shortfall, Arai also talked about their need to improve their combustion system (the all-important power producer in an ICE), Turbo boost is unlimited by the rules, both Mercedes and FERRARI are reputed to be using a maximum of 3 bar boost which is limited by the maximum fuel flow permitted, to be able to use that sort of turbo boost at the maximum fuel flow permitted without running into the all destructive detonation, they both have the “ specialised fuel” to do so, and also they are making use of the maximum number of sparks permitted by the rules per cylinder per engine cycle (rules, single plug, single coil, maximum 5 sparks per cylinder per engine cycle). This system is said to minimise detonation apart from expanding combustion for a longer duration during the power cycle (crankshaft degrees).
