F1 V8 engine running @ 20.000rpm on a dyno! *Video*

Pretty insane, and the sound :shock:

the say that the have now a engine that will do 21.000rpm :shock:

21k RPM is an amazing feat.

 

[Renesis]

imagine if they had rotary F1's

 

[hajj]

Dont think rotary engines are allowed by the FIA

Why are the engines reving to 21k rpm?? This years engine dont rev that high, arent the V8's meant to last for a while (eg 2 or 3 races or something?)

 

[p0w3r]

the V8s are also lower displacement, so they can rev higher safely

 

[jayjaya29]

The 2k more revs over this years v-10 engines makes up for the 2 lost cylinders.

So basically they V-8's rev higher then the V-10's to make up for the lost horsepower.

the reason they rev the V8's higher is not to make up the power defecit (though that is the end result), it's purely because the V8's *can* rev harder than the 3.0l V10's, and with F1 motors revs = power, so they rev them as hard as they can. As said above, the V8 can rev harder due to it's reduced moving mass (pistons, cranks etc) which results from the lower displacement.

Of course a 2.4l V10 would rev higher still...

 

[jayjaya29]

Yes a 2.4 V10 would rev higher, the main thing in revving this high is to taking into account the moving parts. The pistons and all other rotating parts have to handle the amount of pressure they are under while moving at 21k RPM. I think right now the pistions undergo 7000g's of pressure in the V10 engine. So you have to have really good materials to rev that high.

and good hearing protection

thinking of the pistons belting away at 21k rpm just amazes me though

On a tangential note, does anyone have a link to the F1 engine playing some piece of music?

^ you mean like in the Honda tv ad? or an engine playing a piano?

Acceleration.

Sorry the engineer in me is coming out. haha You are right though. The internals of these engines go through a stupid amount of stress during a race.

 

[jayjaya29]

Yeah, I suppose you can say I'm wrong. Its still amazing.

 

[Labcoatguy]

^ you mean like in the Honda tv ad? or an engine playing a piano?

I suppose the latter; this one would be where a certain RPM would match to a specific note.

tit's purely because the V8's *can* rev harder than the 3.0l V10's

the V10's can rev harder as well.
an engine keeps increasing revs as long as it can keep sucking in air. so if you put the headers of the V10 on the V8 (which has less dissplacement) it will rev higher so it consumes an equal amount of air/min.

so if you put bigger headers on the V10, it will rev higher as well. but you do have to make sure all your different parts can keep up

There is a dance track that uses a sample of an F1 engine in it. I have it on my comp but can't remember what its called (and I'm not going through 6500 songs for ya sorry)

I'm sure someone else has heard it. Its got a guy saying SCHUMACHER through it.

 

[ArosaMike]

Well someones gonna get sacked at cosworth! They sound surpsiginly similar to the V10s actually, which is great. I big into engines so it's really cool to watch that!

Yeah, but just imagine it for a moment, it would sound like a dentist's office instead of a race!

Yeah you are right, a rotary engine would rev far too high, it would sound funny!
