F1 » Hamilton: There is always room for improvement


ProfessorX:
really Sunny, do you really believe that? You do realize how easy it is to shift the weight of the car rearward right? It's an optimization game, and Merc STILL have it in the bank, more lateral movement and a larger envelope to play in. Ferrari are definitely improving, but what your saying makes no sense.
. Profs, If as you say what I said doesn't make sense, it means that what you said makes sense, but for the sake of those reading us. Paddy Lowey (the enforcer) said, "China is front end limited". which means that contrary to you he knows how easy it is to shift weight, which is limited by the rules stipulating that, weight on Rear wheels 53.3/54.5% minimum 366kg, and weight on Front wheels 45.5/46.7% minimum 311kg.

F1 » Hamilton: There is always room for improvement


And in addition to my post/s about the two configurations/modes the PU is used during qualifying and the race with the resultant differences in power outputs. The information I have says that all four PU’S on the grid are just tipping the scales at a combined power output of over 800HP for 33.33 seconds per lap at a boost of 3bar and maximum fuel flow rate of 100kg/h at 10500RPM with wastegate/s opened, with the differences that two of them are being forced to run at much reduced output for various reliability reasons.

Mercedes will rush forward (from the planned for Spain upgrades) to China a new front wing and a new diffuser in an attempt to combat tyre Wear (degradation). FERRARI will introduce minimal updates in China, and will concentrate on their as planned upgrades for Spain. Contrary to what has been said track and ambient temperatures differences or not between Malaysia and China, tyre degradation in China will be a problem, but this time it will affect the fronts more than the backs. Wishing all respective fan boys the best of luck.

The following technical information pertains to FERRARI, numbers/calculations are from Barcelona race track. First it is important to understand the rules/regulations constraints, ES maximum capacity 4MJ. MGU-K output to engine maximum 4MJ/lap. MGU-K harvesting maximum 2MJ/lap. MGU-H output to MGU-K, ES and compressor is free. MGU-H harvesting is free. The turbosupercharger/MGU-H is used in two modes, race mode with occasional overtaking/defending boost mode and qualifying mode (full boost mode). Qualifying lap at Barcelona race track, the turbosupercharger wastegate/s are open (engine exhaust bypassing to tail pipe) and the compressor is at full boost (3 bar) ran by MG-H with engine at full fuel flow at turns 1-4-7 and 10 and for the rest of the permitted 33.33 seconds of the lap. In this mode the engine is at maximum power. To be continued.

Continued, with wastegate/s opened the engine gains 20kw/17-30BHP but in the process the MGU-H has to use 60kwof power from the ES to power the compressor. With the wastegate/s closed the 20kw/27-30bhp reduction in IC power is compensated by 40kw generated by the MGU-H. Hope that some will find this information of interest and that it helped kill some waiting pain.

I don’t see anything wrong neither in what Lulu said nor in the headline, as room for improvement/s on a formula 1 car and in operating it only stops when the project at hand is written off. From time to tome there are days like this that hits all websites (slow news) but this is not helped any by us regulars because all we seem to be able to banter about/push each other at, is my driver/your driver my team/your team, in short we excel only about fanboyism, when there is so much more to talk about in this sports we follow more so at a time like this. I will take this opportunity to lessen this “China waiting pain” and take the opportunity to share some very interesting technicalities that with others on here that might be interested, “like me” are always trying to understand and “better” their knowledge of the F1 technicalities, so with apologises to Lulu, his fan boys and those not interested and also to the purists re the proper topic/s. Please read on my next post.

Race mode, the wastegate/s are closed, the turbosupercharger is ran by exhaust gasses, the MGU-H harvests when off throttle, also harvests and regulates the maximum turbosupercharger RPM, when occasional boost is used the wastegate/s are opened and engine goes on full fuel flow and boost, in this mode engine power output is less than in qualifying mode, except when in boost mode. In qualifying mode the (wastegate/s open) engine power output is + 27-30 BHP more than when wastegates are closed because of exhaust back pressure with closed wastegates. To be continued.

F1 » Teams play down Mercedes engine parity concern


But can a PU that has not been used have a hardware development improvement added? If so, can it be applied to the works car units in isolation? Because that is what Fernley implied. A repeat, A PU (hardware) that is in use/being raced cannot be developed upon (have developments added, but software can be modified/developed, if the PU being raced/in use is replaced with a PU with added development tokens, the PU which it replaced cannot be re used because it becomes the latest homologated unit. There might be two different SPECIFICATION PU'S in use by those using the same make of PU, but that will be because when a developed PU is pushed into use by one team, another might still have the original PU version in it's cycle (being used). I know that its Fernley, but What Fernley said/implied was wrong.

F1 » It’s not been a perfect start, admits Rosberg


zib:
107SS2009: Toto Wolff 13 march, “Another re-think will also take place at Brackley”, “Maybe with our very fair-play ideas....Maybe in future we need to make decisions that could be a little unpopular with the Germans or the English”.
If Nico is not able to hold off Vettel, things ll get tough for him. Let's see.
And do you think that Lulu would have been able to hold-off Vettel if he didn’t dive into the pit entry?
