F1 will see a complete change in engine regulations in 2014, and we're having a closer look at what that means exactly
I wasn´t told the details, but the turbines they used at first were simply overchallenged with their monumentous task. So you are right with your assumption. But I don´t think the picture shows the turbocharger we will see in 2014.The turbine shafts will probably have to be larger then normal to run closer to "Shaft Critical Speed" that these turbos will be running at to maintain the high load for efficiency the MGUH will require.
Ferrari supply the gearbox to both Sauber and STR. RBR supplies a gearbox to Caterham. Not sure who Marussia use, since they are the only ones with the Cossie. Maybe still X-Trac?Holm86 wrote:They all build their own. And Williams does as well. Don't know about Lotus but I also think they build their own. There's only Caterham, Marussia and possible Force India who doesn't build their own boxes.SectorOne wrote:How many build their own gearbox?
Ferrari, Red Bull, Mercedes, Mclaren? Or do they use Xtrac?
I have no earthly idea. I did a lot of reading on the BMW turbo project and some of it written by Rosche himself but I have never come across that bit. But 1000 Nm at the time must have been very unusual in a racing machine.xpensive wrote:In 1985 when Nelson had 1300-1400 Hp in quali, the torque entering the gearbox could hit 1000 Nm, but I have heard that this gearbox came from an old 1943 BMW tank prototype, when the company tried desperately to compete with the PanzerVI.
Isn't that true WB?
Well....hopefully technology analytic's has improved over the past 20 years.MOWOG wrote: "We will go back to a time such as 20 years ago," Mercedes team boss Brawn is quoted by Auto Motor und Sport. "The technology is so complex that I expect a lot of failures. So there will be a new element of surprise," he predicted.
I'm thinking 38 tons might be heavy for an F1 car. LOL.WhiteBlue wrote:BMW designed a tank hunter prototype "Rutscher" in 1943-45 with a 3.5 L I6 engine and an Allklauen ZF 5-25 gearbox.

The group 4 version was naturally aspired but the group 5 version had bi turbo. The late M1s were assembled at Ron Dennis' Project 4 factory in England. The late turbo version used in America was topping 800 bhp reportedly.xpensive wrote:But that Procar 24-valver was never turboed, still had 450 Hp, right?
