Maybe so, anyway hopefully we will have announcement from Mclaren next week.Thunders wrote:True, but this Year winter Testing starts later. And i don't know if PP pulls a Newey and wants to develop until the very last second.
I was not denying the problems that they faced running the turbo. I was just saying what could be the original reasons for them going with a high rpm concept.hemichromis wrote:I understood that the major problem was that when the turbo was spun to the high speeds it was designed for it caused vibration?!PlatinumZealot wrote:The reason why Honda chose a higher rpm turbo first time out is for reasons of spool time and efficiency... Yes. Efficiency.
The faster the turbine spins the more exhaust pulses each blade can capture. You get a better use of the pressure pulses. If you design your turbine for a higher operating speed you can be sitting pretty if everything else is perfectly aligned. You see the exhaust pressure pulses are many times faster than the rotor and some of that energy is wasted as reversibility when the hit the rotor. Honda was probably hoping that they could achieve a steady turbine loading throughout the lap and run the turbine at a higher rpm reaping these efficiency benefits. Their turbine map is designed around this high rpm range too. Real world problems obviously put fire to their concept though. The MGUH was not strong enough - poor charging to the battery.. high back pressure from the small turbine.. leads to higher combustion chamber temperatures.. not a flat enough compressor map coz the compressor is small... a whole bag of problems. I think now they realize that the pulse usage efficiency of the turbine is a secondary importance to the efficiency the MGUH and a larger turbocharger can make up for.
Where did you get this information?
I expect McLaren will launch the MP4-31 (perhaps in early February rather than the end of this month, given how late the tests start compared to previous seasons) with it's basic design philosophy on show, then roll out the test package for the first winter test. Or do a press event on the morning of the first test in the pitlane before testing starts.Thunders wrote:True, but this Year winter Testing starts later.

I think that was only 177th time.....GoranF1 wrote:for 178th time....no new parts at Pirelli wet tyre test!
It's ok mate...CjC wrote:Thanks!
And hey I won't bother asking anymore questions to get the answers that I didn't know as I am clearly wasting your time
.....at least maybe Honda has work out ways do run full deployment for a larger amount of laps,whitout making any changes to hardware.
STR will use the Austin spec.Big Mangalhit wrote:So no new parts on the wet test, that is a given. I do wonder, though, is it possible to run the last spec 2015 engine, with all the tokens used, even if the engine was only run last year on a dyno and not on track? Like for instance the full token used 2015 ferrari PU that STR will probably use.
