Mechanics I assume?
So Solberg has lost his top mechanic and number 2 driver? Yes mechanics. Wonder when Hvaal will show up again. |

Are the Peugeots 2 litre or 1.6?

Ok so the problem is down to them over stressing a smaller unit then. I'd have thought the Peugeot engine is pretty mush the same as that in the Citroens isn't it? So why are they failing more in the Peugeot?

If Peugeot were building the engines in house I could see them having issues producing a reliable engine with double the power demands of the R5 specification, but Oreca should be able to produce a reliable engine, shouldn't they? |

I understood that the engines that Peugeot used in Group B times for the 205 T16 E2 were very reliable. I'm no engineer, of course, but wonder if those engines, updated to 2014 standards, would still do well. Back in the days they produced 600+bhp with 1760cc (x 1.7 = 2992cc = 1210kg), without air restrictor. Not with up to 2056cc (x 1.7 = 3495cc = 1300kg) like most SuperCars currently run. For to have a weight advantage of 90kg one doesn't need a 1600cc engine, but can go up to 1760cc... |

Having a 1.6 lit engine (or 1760cc) puts more pressure on the engine and to have it running strong, like a 2 litre, you would a higher RPM. The car may be quick but at faster tracks it dosen't benefit you. Unless its a wet race of course. Frode Holte for example has that problem now, using a 1,8 litre engine in his Hyundai that isn't fast enough for the faster tracks. Laboulle drove a Xsara with a 1.7 litre engine in 2012 if I'm not wrong. Though tracks in France tends to be a little slower, it suits a smaller engine perfectly. |

Liam Doran won X-Games Munich with a smaller engined MINI: sure that was a wet race as well (and quite a slow track). |

I think the last team to build works engines in house were Citroen in the mid 90's werent they Ed?
I am sure JLP and Kennth had factory Citroen engines? And am also sure Kenneths early ZX at least used a 205 based motor before moving on to modern ones later. Wills Peugeot certainly used 205 engines. Not sure MArtin ever had factory engines, he used lots of engine builders in the Escort initially, efore I think building his own. As far as I know Keneth has used Oreca for donkeys years so no reason to change. Them and Pipo are the better rallycross b uilders with Godfrey. Ford use Mountune after Carlssons did Erikssons engines for a while, and Mountune are real engine heavyweights, perhaps explaining why those cars are mong the quickest. |

Besides, the Group B cars had little regulations when they were built and had a lot of freedom to do what they wanted with the cars. There could be more to it than just engine size. I'm not an engineer or mechanic either though |

Such "big" engines as Schanche was using back then are not eligible these days anyway. The limit for a turbocharged SuperCar is 2056cc for quite some time already.

Think the Peugeot was a far superior handling car . Is Blocks Fiesta the transverse engine ? 1.6 or 2.0 ?

2 litre. In my opinion he probably has the best car and engine in rallycross, as close to a manufacture rallycross car you can get right now except for the upcoming GRC Beetle

It's transverse as well. There was a great online primer on RX in Racecar Engineering. They showed which cars had what was really interesting. I also concur that the MSport car is a better solution than Oseberg's right now.

Yep, the Peugeot was defo better handling. At least before Schanche got his RS200s sorted out. But you know as good as I know that in pre-Joker Lap times the winner of the start was in 80 to 90% also the winner of the race. There was not much overtaking coz of better handling, rather after the leader made a driving mistake. I think the package of that perfect 1.75 litre engine (with Pikes Peak gadgets) with its weight advantage helped Alamäki a lot to claim his three consecutive titles.

A bit different. When Niittymäki run his 205 T16 E2 in 1987 there was still the turbofactor 1.4 in use. His engine had 1775cc, the weight limit for cars with 2.5 litre engines was 890kg back then. One year later Alamäki had 1760cc (x 1.7) and its 3.0 litre weight limit was 960kg.
