Red Bull RB8 Renault

Obviously it's a component that would be very sensitive to surround airflow/heat/vibration, so not entirely surprising that it's okay in other installations.

According to AMuS it was the bearing of the rotor.

Lotus have 1 failure - Grosjean in Valencia. So 2 for Red Bull, 1 for Lotus.

Red Bull have had FOUR failures. Two for Vettel in races, one in practice. And one for Webber in race.

Lotus have also had failures in testing, as have Caterham.

Actually - the R30 Pirelli uses as test mule has had quite a fair share of failures. Have Renault been using that as an on-track dyno?

From the article, it sounds like basically they made modifications and fixes to the 2012-spec alternators (which, let's not forget - was reliable all the way from Melbourne to Valencia, and then Valencia to Monza) and they're fielding those. Not any special designs AFTER the failures.

Yes, it sounds to me like the other cars that use Renault engines used the new spec alternators in Austin. No problems from them so RBR feel like its the best way to go.

They more feel like they don't have 2011 specs any more ...

Hi. It was mentioned by Renault that the alternators suffered in low RPM corners
here:

Ok, its logical, in the low RPM range less current is produced by the alternator.

Just look on the graph.

As I'm understanding the article, the alternator suffered because of overcurrent. Either Renault went over the limit with the new alternators or the car is simply demanding more current than the ALT produces. There were some talkings about Red bull using separate tanks for cooling fluids and oil, so they can pump the fluids all over the car, just where they want the additional weight. Those pumps could draw too much current in low RPM.

Cheers

Interesting thought ziggy and well done for thinking of a completely new cause for the problems - and for supplying backup data to go with it. If I knew more about that stuff and could verify it's plausible I'd +1. Does anyone know if this is conceivable?

Isn't it 3 for Red Bull now, Vettel=Valencia, Monza. Webber=USA

Thanks.

Only Renault powered cars can run these separate tanks because of engine reliability or cooling issues and only Renault powered cars suffered from that failure, even Caterham. Sorry can't find the link right now.

New RW for the USGP

It's interesting how they quickly adapt upgrades by others (ie. sauber exhaust). Deffo less time than Merc's coanda exhaust.

fortunately the Brazilian track has not as much slow corners as the CotA

Ya, would be interesting to know their experience with the DRD from YDT. I wouldn't be surprised if they were the first (along with Sauber) to make it work properly.

What does this have to do with the RB8?
