Me too. I dont see other option. At least from ABD and Jerez tests....frosty125 wrote:From what I have heard and seen the Compressor is at front.
According to the autosport+ article, Arai is quoted saying it's a quality issue and not design.Facts Only wrote:I've just re-read the Autosport story and the quotes from Honda and they both use the Terms "faulty" and "redesign" which are contradictory. Either the seal was faulty (IE Not made correctly to the design/quality requirements) so should just be replaced with a non-faulty item or the design was wrong in the first place in which case the seal wasn't faulty, the design was.
Perhaps they mean that the sealing system is faulty, IE that it doesn't work as intended due to an oversight at the design stage. From experience this can happen quite often as a few microns can be the difference between a seal working perfectly and oil/coolant pissing out everywhere (anyone remember the dyno' fire at HPP?) so can be a bit of a trial and error process.
With it being a 2 day turnaround I doubt they are changing the design of a rubber component as there isn't enough time to re-tool, likely if will be a change to the size/interference/tolerance on a machined housing that can be re-designed and re-made in a matter of hours.
That's just my speculation anyway, I don't think this is a serious thing at all but it is losing them valuable mileage.
I don't know. Just saying that shaft seals are a bit complex to redesign and make in a day. So I figure the seal is off the shelf if it is a shaft seal. ( A whole bunch a stuff in the lip of a shaft seal).WilliamsF1 wrote:PlatinumZealot wrote:But you just don't redesign and build a seal then assemble the MGU-K on an engine then ship it to Spain in a day.
Therefore the seal has to have a fast lead time. If the seal is for a shaft, then this means it must be off the shelf. If the seal is just a gasket, hover, then I can sorta see them redesigning, manufacturing and installing it on the PU in a day.
Isn't the MGU for Honda made by Mclaren?
They would not use that kind of seal in the KERS. The seals you see on high speed shafts don't really look that that one.tok-tokkie wrote:Seals can be cnc machined from bar stock. An example http://www.alibaba.com/product-detail/C ... 80953.html
That's still enough time to do race simulations and qualifying simulations. They need this test to iron out the rest of the engine issues, the next test ideally they would arrive with a race spec engine and hopefully 2 cars. Let's not forget Honda aren't alone here, Renault have made quite a big change to their engine and are also experiencing some issues. Let's hope Alonso get's a full day of running today.bauc wrote:From Ted SkySport's F1:
"McLaren tell us that the engine hasn’t run on full power yet, so they don’t know where they are at the moment. It’s a very difficult situation for them. Aerodynamically, it’s an adventurous car but they just don’t know if it is working yet because the engine and the energy-recovery system isn’t working yet!"
I'm starting to get worried now as (not counting today) we have 6 more pre-season test days left

Probably just excess Oil.
Oil levels wrong again? McLaren engineers showing their frustration by burning it in front of the engine guys?Thunders wrote:Can't be that bad if McLaren tweets such a Pic.
