The key question with such an idea would be to work out how best to equalise the engines so that the backmarkers and old technology does not outperform the new machinery.

And which teams should be equipped with the V8? Only the backmarkers Caterham, Marussia, HRT or more "small teams"

Helmut Marko wrote:So far we have developed the current car down to the very last race. We have also pushed the parallel development of next year’s car. That has served us well so we will stick to it. Sure 2014 is in our focus as there will be fundamental changes. But the main point will be cooperation with the engine supplier, as it is there where the biggest change will happen. We are waiting on the final rules for the 2014 cars and my guess is they will immediately follow the signing of the Concorde Agreement. We have a very close cooperation with Renault and are in the loop with everything that is happening there.

It is very annoying to see that we are spending huge money on new developments when the world is collapsing around us. But these decisions have been made; the door has been closed behind us and now we have to find the most reasonable way.

• will there be an equivalence formula for the small teams to keep the V8s and how will it look like?
• will they agree to a separate limited budget for power train development from 2014?
• will there be more technical liberations in the years to come?
• will we see sales price caps for engines?
• will there be more manufacturers like Honda and Porsche?
• how much power will be available from the compounding function?
• how lean are the new engines going to be on fuel air ratio?

1 equivalence should be offered via a 10% higher fuel rate

2 compounding power is an artificial concept
(all such schemes cost some crankshaft power (by increasing exhaust pressure upstream ofthe turbine), and conceal that cost)

IMO mentally adjusting the recovery of the Wright 'Tubo-Compound' for our very different CR, boost pressure and compressor load suggests genuinely free recovered power of 10% ie 65 bhp
(improving efficiency in-cylinder eg from 2014 injection reduces scope for turbine recovery)

more recovery is possible, but is only 'free' to the extent that it outweighs its cost (in crankshaft power)
rule changes could force this
such recovery would be done by heavier loading (than in 3) of the GUH to give EGR effect with rising rpm
(to maintain both constant (before-ignition) cylinder pressure and constant massflow over the normal rpm band)
this is thermodynamically better than loading as in 3 below (because it uses optimum CR throughout the rpm range)


3 FAR 99% - 101% stoichiometric generally

the GUH load will be increased as engine rpm rise, controlling the turbine rpm to give constant massflow matched to the constant fuel flow, giving compound power and maintaining 99-101% FAR (simpler strategies have less scope for energy recovery).

leaner running would only occur in the lower gears, when there would be a little part-throttle time and leaning is useful

From what I see it is sporting a twin scroll turbine housing similar to the Audi LMP1 engine.
The light blue part at crankshaft height should be the MGUK and the MGUH lies in the vee.
The intercooler looks a little bit small in my eyes regarding the huge air flow. Also the placement between the tank and the engine makes no sense in my eyes from a mounting point of view and in the way cooling air has ro be ducted there.

IMO the layout will definitly change until 2014. The installation on the dyno may be a hint that the definite intercooler is in the side pod. But dyno and car a at this stage two different things.

If you read the interview in Racecar-engineering (as posted before by WhiteBlue and Scarbs) Rob White describes this picture as "very provisonal" model that shows the basic design guide lines of 2014 regulations, not the cad drawing of actual engine.

That is not going to be the case. There are some other things that are misleading.
The engines wont even need 1 bar of boost to produce the 720hp range. When the writer says they will have 2 to 3 bar and yet be less powerful, it's even more obvious he doesn't have a strong grasp of the subject.

I cant remember what was the fuel flow limit right now, but his boost pressures are way off. You are looking at over 1 thousand horsepower with 2 to 3 bars at 12000rpm, not to mention 15,000!
