Williams Toyota 2007

And it can rev to over 21,000 rpm

[Pitwork]

The Cossie engine is still one of the best on the grid. It's more powerful than the Toyota and the BMW... sonic analysis reckons it's putting out 755bhp at 20,100rpm.

But that power don't mean shit if the engine blows up on the first lap.

huh? i always thought f1 engines were capable of at least 150 more horsepower, or im not up to date and those are the power figures of the new V8´s?

[fpv_gtho]

Youre probably still familiar with the V10's, which were 900-950hp

Sonic Analysis? The can work out the power by analysing the sound?

Oh yes. It's all to do with sound pressure levels apparently. They can also analyse firing orders (with a 'super-stereo' mic), efficiency and revs.

Oh and the cossie V8 revs to 20,100rpm in qually and 19,600rpm in the race - not quite at 21,000rpm yet.

What they do is measure the revs the engines do which is the actual sound analysis part, then sub that into a generic formula to estimate power. Its the same sort of stuff where they predict race stints based on how long the fuel nozzle is connected in a pitstop. That all uses a generic fuel consumption figure
