Whats the problem with this, sounds ok to me, still have the same BHP, as now 750, will be smaller, use less fuel so the car will be lighter. Energy recovery, ie kers so embracing the new tech. Dont forget the mid 80's BMW 1.5 turbo cars had about 1300bhp in Q when set to 5.5 bar and 800 for the race and they where pretty special to watch too. http://www.productionparadise.com/spotlight/cars-and-landscape-photography-324/rainer-w-schlegelmilch-12283.html |

You are correct, it was a bit of knee jerk reaction from me to the hierachcy chipping away again at what is supoossed to be the pinicle of motorsport. Thinking about it, that sort of power with todays aerodynamics might be something special. |

Rev limit of 10k is going to stifle things a bit.

The old BMW and Zakspeed 4 pots had a max of 11500.
Most 4's produced max power at about 9500 I think with tons of torque.The 6's reved higher as you would expect.
Capping revs is not ideal but 10k should be ok. If they need more should be easy to up the limit a bit.

Unusually, I'm with Bernie on this one - why bother, especially when there's not much money about. They think VW will be keen, but I bet a couple of others will drop out. If Ferrari and Mercedes didn't back it, that only leaves Renault
Did I say VW, I meant Audi, so at least some of the diesels will be off the grid at Le Mans

Bet you they won't be fuelling up with the "rocket" fuel used in the original turbo era.....85% toluene amongst many other interesting ingredients.
and I suspect that they won't be running at 5.5 bar boost - that was Berger in qualifying at Monza in '86 (I think) before they started restricting boost.
As a volumetric equivalent of a normally aspirated engine, in a turbo engine each bar of boost doubles the effective volumetric capacity (rather like compund interest). So, 1500cc at 1 bar boost is the equivalent volumetric efficiency as a 3 litre engine, x2bar = 6 litres, x3 = 12 litres, x4 = 24 litres, x5= 48litres etc.. you get the idea. That's why turbos are so effective -but the higher boost you go, the finer the control has to be over the fuel, timing etc. That's why the qualifying engines in the 80s were "hand-grenade" specials running at 4-5 bar in qualifying and 2-3 bar during the race, and why mixtures were run rich to help valve cooling and prevent lean running - led to the lovely overrun flames....
Lots of other factors came into play, such as the tyre wars of the time, fuel concoctions, and the fuel limitations on consumption during the race. I suspect it will all be a bit more controlled now....

I'm as big a fan of the turbo era as anyone, but I agree with MGM on this one, I suspect the turbos this time around will be quite a bit more regulated than in the good old days of the mid-eighties. Those were very special days, 1300 BHP for qualifying around the old Österreichring was some prettty serious stuff, definitely a man's game back then. That said, turbos will be an interesting switch, but I doubt we'll see them allowed to get to the sort of horsepower figures we saw in the eighties.

Indeed, and some may remember the rather less than controlled (but jolly spectacular) Arnoux/Villeneuve duel from the early turbo days in '79 in France when 1500cc turbos were mixing it with 3ltr normally aspirated http://www.youtube.com/watch?v=kl2tIFxSEGA&feature=relatedenjoy, along with murray commentating....
