Power/Torque on a F1 car?

you could well have a point there, I just took the figure for granted. It looks more like a figure for a turbo engine or a diesel.

[DasModell]

no N/A petrol engine that i know has more then 130 Nm/L ..

[henk4]

yes, b.t.w. did you get my email that I sent you through the ten tenths forum?

[DasModell]

yes .. and i replied ..
did another try . i've put it in the sports;car&Gt forum also .. maybe ..

[henk4]

so I noticed now, not Dani either

[DasModell]

is dani filth a romanian name .. don;t think so

[henk4]

to me it's a filthy name, I'll be in Romania in the final week of November, most likely in Bucurest only, may be Constanza too.

[DasModell]

lol .. yeah .. i think that what it is .. a filthy name . .. it a british band vocal name ... but i'm afraid i'm stuck witt it .. on ten-tenths .. ... on other forums .. thwy call me "modelu" de la DasModell

you said you've been around before .. did you have the pleasure to taste our wonderful wines ????? home made????

[henk4]

I had some, but it didn't make a lasting impression. (neither negative nor positive).

Had to reply to this one. The torque of an F1 engine is approx 325 to 375Nm, right about what Reek says

As for the torque/horsepower coments, have a look at the following, this should sort you out.

Lotus 49 Cosworth DFV power/torque curves ..



using the formula ... BHP = torque X engine_speed / 5252 .. u get 233 lb-ft ... blah .. i didn;t do the math .. myself .. can someone convert those to normal figures .. i mean . Nm ...
anyway .. 233 lb-ft ... at max power rev .. as u can see in the graph ... but max torque is something around .. 250 ... at aprox. 7000 rpm

[ReeK]

400 BHP ~ 300kW
250 LbFt ~ 336Nm

So the torque from the DFV isn't much lower than current engines, but because it developed it at half the rpm, that's why it develops about half the power. Which again proves that Power is more important for a race-car to accelerate...

[JJ72]

Torque is power.
Horsepower is the work done.

you need torque to get the acceleration while Horsepower determines how fast you can accelerate with that force...actully mush more than that but i can't explain it well.

and probably a wrong explanation too.

but the need of torque correspond to the mass of the vehicle.
a light car require less torque to accelerate. and for a F1 machine, which is surely very light, can demand less Torque.

Bravo, excellent article good job figuring it out. Excellent discussion here.
