You pray you can find one.
Or you can plan in advance and have one spare. |

Is there any word on who the supposed OEM branded Ginetta is?

the DSC article said:
"expect an OEM-badged engine deal for a manufacturer never before seen at Le Mans." So I'm thinking someone like Volvo or Hyundai......so a decent manufacturer that wants to transition to a brand profile like Audi, BMW and Mercedes have......20 years ago Audi were nothing special, now look at them. |

There was the Dacia/Wizzair rumour doing the rounds a while back (sounded pie in the sky to me ), originally linked to the sale, then no sale, of the 2 Perrins, I believe. Perrin indicated the programme would still emerge, but with a different LMP1 manufacturer.
But that's pure speculation on my part. Who nows, until... |

Random post: Ginetta has turned a profit.
"In its accounts, LNT also report that Ginetta made good progress in growing its markets and increased turnover by 49% to £9.2m. International exports accounted for 28% of all Ginetta’s new car sales in 2017 due to the expanding model range in to sports prototypes and the competitive success of their GT4 model globally. As a result, Ginetta made its first gross profit in the year. The company said this demonstrated that the long-term strategy of sustained investment in product range, and manufacturing capability, is on course to deliver a programme of improved profitability in future years." http://www.thebusinessdesk.com/yorks...Nov_2017_Daily |

Mechachrome 3.4 V6 = LMP1 engine porn.....i am convinced whoever uses this motor will be flying.

Something goes beyond my engineering understanding, but what's the deal to make an engine rev up to 9000rpm when max power is achieved at 7000rpm?
wasn't better to make a milder torque curve but max power reached higher? basically like a NA engine (or ford GT GTE engine). |

I would like a proper explanation of that too. But I guess if you can safely rev past peak power then you can change gear and drop back to somewhere near the torque peak and so maintain acceleration. Maybe you can accelerate better in a lower gear just past peak power than you can in the next gear up at lower revs.
And you can safely 'over rev' past the power peak if you are slipstreaming. I'm making this up, obviously. |

I think they have been incredibly conservative with the torque and power figures released. For this capacity i would expect 8-900NM torque, and to be comfortably wellover 700hp.
Regarding revving to 9000rpm.....i think it boils down to how much fuel in the tank there is to burn, versus tank capacity, pit strategy and so on......the engine can be run quite hard, but if you can achieve competitive pace via short shifting and saving fuel, then thats the direction to go. F1 engines only rev so high as the FIA mandate it to make noise and keep the fans happy, but the F1 engine folks have openly admitted the same track performance can be achieved with drastically less rpm, but the engines will otherwise sound dull as hell. |

Indeed endurance single turbo engines with an insane pressure boost are all small sized, not over 2L (porsche V4, SGT L4, mazda AER L4). About rpm, guess that's the simplest solution. ECU lets the engine rev up to 9000rpm, but being max power released at 7000rpm already, short shift all the way. Actually is the same about 488 GTE, according to bop sheet, car loses turbo boost at 7100rpm (or 7500rpm, only in IMSA maybe) but during onboard, drivers always upshift just passed 6000rpm |

It is not so different from a Porsche 962 engine from the IMSA GTP era. Even it had almost the same power with 2.8 L.

Due to straight line testing in December, at least.

I'm beginning to doubt that anyone other than Manor has committed to Ginetta, so maybe they will run a factory car themselves, even if only at Le mans. Alpine may see a class win carrot in P2 as a better option than a P1 programme . Hope i'm wrong, i don't feel they should even be allowed in P2 this year.
