ENGINE DETERIORATION

[adam2007]

what percentage of bhp does the engine lose after every race weekend, so from the first race to the 3rd whats it lost? also what time would u loose couple of tenths of performance??

I would suggest you ask the Torro Rosso guys, they know all about being saddled with old engines!

Ive heard that there is up to a 30% dropoff when a engine enters its 3rd full race weekend. No source tho, so it may not be verified data.

Dude.. no one here would know that.. how many horsepower are lost per race. Or at least no one that could talk about it.

Seems like the Toyota engines have been running pretty well, racking up the most miles.

Sucks for Kubica to lose an engine (#5) after only 30 km. He's got only 4 left before being penalized. I think that will eventually happen because I just don't see him running all season with what he got left.


Note to admin: can you change the case of the letters? All caps is kinda silly.

To answer the question of power drop-off from race to race, I think one has to define power first.

If power is Rpm times Torque, and you don't lose any Rpm, then it must come from loss in torque, right?

And from where in the engine would that torque-loss come from? Leaking valves or piston-rings, clogged-up xhausts or injections system, wear on main bearings?

The Toyotas have been really running well, on the relyability charts they are first.

If you take the relyability as this; Ammount of miles raced over ammount of engines blown/no longer in use, the charts are like this:

Toyota RVX-09: 26780.545km raced, 6695.136km average, no blown.
Ferrari 056: 22205.115km raced, 5551.279km average, no blown.
Mercedes FO108W: 33082.008km raced, 5513.668km average, 2 blown
Renault R27: 22262.336km raced, 5565.584km average, 2 blown.
BMW P86/9: 11100.343km raced, 5550.172km average, 3 blown.

Sutil and Vettel may just beable to do it thru the rest of the season, with some management, I suspect they are both gonna have to do 4 races on one or 2 races just to get back in sync.

Kubica, he is gonna have to take at least one penalty, but im shure with some management he can struggle thru, but struggle he must do, it may mean that his #3 engine can do one more full race weekend, and im shure that his #1 can be used for Fridays, meaning that with some creative management, he can make it thru penalty free.

I can see more blown engines tho, at least 1 more from BMW sauber and at least 2 more from Renault, maybes 1 from Ferrari and Mercedes. I can see Toyota being the most relyable for the second season on the bounce.

Stark contrast for BMW to last year. They need to scrap that crappy synthium oil, and use a real brand.
