From what I read, 2013 F1 turbos won't have wastegates and will instead regulate turbo pressure electronically. Is it possible with ACO rules? And how does it work exactly without a wastegate?

Dont get too excited about ceramic bearings, they are nothing special and INA/FAG still offer many exotic all steel turbo bearing options that will work just as well. felix - regarding waste gates, from where I'm sitting thats really not the case, but things may change, in all honesty I'm not a wastegate expert, but I know people who are and the implications are that waste gates are here to stay, they are just too well proven and accepted for a silly regulation to bin them.......check out this mob (DSPS) for waste gates and fresh air valves (for turbo anti-lag (reverse EGR)) for the new 1600CC turbo WRC regs: http://www.dsps.eu/index.html http://www.dsps.eu/2011_wastegate.html http://www.dsps.eu/freshair_valve.html The fresh air valve is basically an evolution of the first system pioneered on the 2001/2002 Hyundai WRC engine, designed by clever folk at Mountune ;-) |

The reason why the Audi and Aston V6s are at least 90 degree is because the CG on a 60 deg engine is higher up--that was a problem with the production based V12 in the old Lola Astons--heavier than the Audi and Pug V12 diesels and a higher CG.
Also, if a 60 deg block is used, where's the room for the turbos of they're housed in the V? At least 90 degrees is what we're looking at--60 degrees is optimal for a V12, but Audi ran a 90 on their V12 because of CG and what not. I think that 90 or 120 is what were looking at here for packaging and weight/CG. |

Who says that Aston Martin are going to go for a turbo installed inside the V? Let's not get ahead of ourselves with assumptions again.

Indeed. Don't forget that the Aston Martin will be a spyder. So moving the turbo(s) to the middle of the engine makes less sense.

Gwyllion? That says they ARE allowed? Ceramic is allowed for those specific bits n pieces.
If twin turbo, AMs job is easy. If a single, then stick it in the vee, as that makes most sense. Even drop it just behind, as CART/DFX Cosworth installation from years ago? |

Unfortunately, in English, that sentence says all items IN the sentence ARE allowed... Anything else, is not.
I have no doubt the original French version states that, but the English wording does not. Unless that is what they actually want it to say? VGT and moving blades are specifically allowed in LMP1 anyway, so I don't see any issue at all, here? Please don't think I'm picking a fight, BTW, I'm not... |

Besides, I like open cars, they're what's been up front through most of the last 10 years and that's when I've been watching the sport. Modern P1s never look quite right (to me at least); the proportions and squary bits are just wrong compared to something like the GT-One, CLR or even the Epsilon-Euskadi. |

Sorry Mr Knighty sir... /end Pedant
Coupe AMR? I have seen a render somewhere, bet on Endurance Crea, of that original side view, with a roof added. TBH, I was more bothered by what looked like a 'Batmobile' nostril at the front. Thinking 60's TV car, not any movie version. Having grown up with 917s, and 512s, PROPER LM cars have a roof on. Barchetta's are little class entries. Despite the 936 and A442! Never mind assorted Audi open models, Bentley was their last 'proper' car. The R18 is a welcome return to the fold! I wonder if some of the reasoning behind an open car, with petrol engine, was the need to use aircon in closed cockpits, or has that gone, while I wasn't reading the fine print? At which point I'm rambling, and you should ignore me. |

Interview with David Richards at the Autosport Show. First part is about the Mini WRC program, then about the Aston Martin LMP1 project.
http://www.youtube.com/watch?v=tEtMi...layer_embedded Single-car entry confirmed for Sebring, first chassis has been manufactured, engine first run on the dyno this week. |

The single car at Sebring is, I think, the ALMS season long Lola Aston?
There's no real 'news' in other words, which explains his total absence from the show yesterday... |

No, it's a single 2011 LMP1 car. Cytosport's car is privately-entered, DR was talking about factory cars.

"-- we'll be doing a few more races in States and in the Le Mans Series"
So does that mean that the factory team might do more ALMS rounds than just Sebring and PLM? |

Possible, considering DR's emphasis on 2011 being a year of getting miles under the car's belt I'd say that they might go for the longer races at Laguna Seca and Road America.

They plan to be there, but the bodywork hasn't been made yet, and the engine only went on the dyno today...
This is just a tad ambitious, IMHO! Still, good luck to them, and I hope they will be there. |

Exactly. Audi has track tested the R18 and doesn't think it will be ready for Sebring, while Aston hasn't even put a car together yet and they think they can make it? More power to them if they can!

Granted, AMR is dealing with a gasoline engine, but even at that, this program seems to be on rush order.
Audi have had the R18 on track since November, but they're not risking a Sebring debut, and even Peugeot may be pushing it with a 90X debut at Sebring as far as a proven car, and we know that they've been testing since the very least September/October, if not earlier, like possibly July. Only reason why the ARX-01e will be out for Sebring is that the tub is a proven design, and the engine/gearbox is proven (probably a destroked 4.0 LMP1 V8 and updated Wirth/Xtrac gearbox from the ARX-02), and that it takes form the ARX-02 the LMP1 design experience, though the two cars aren't obvioulsy directly related. I think that AMR may be pushing it unless they have Audi like plans for the new car (a huge number of 30 hour test). I think running the performance balanced cars until the new machine is well tested is a better choice. It seems that the program got the green light a little late, as Audi designed the R18 back when they were designing the 2010 R15 and the Pug was probably designed in a similar timeframe. It'll be interesting what the AMR timeframe has been so far, as engine dyno testing has only begun and only one tub has been made. |

I asked Adrián Fernández on Twitter something similar to "Will you have an ALMS programme with CytoSport and Aston Martin?". He answered "that's right". He wrote so somebody else that he will do all ILMC races but China plus Lime Rock and Laguna Seca.

So Lime Rock and Laguna with Pickett in the old Lola and Sebring and Petit in the new car?
