Current Power

[Robin Plummer]

Can someone tell me what the F1 teams current engines put out in horsepower and will the power be reduced by next years rules?

[Glen]

Close to 900bhp, or so they say.

The one engine per weeked will change engines quite a bit I think - it's double the mileage per unit. Maybe they'll extend the idea of using diferent engine maps, and still retain the ability to rev to the max, but need to hit the "boost button" (change to a higher reving map) to achieve it. I also think it will change the way that things are managed during the weekend - I'd imagine that as few laps as possible will be done in practice.

BMW - around 925-930 BHP
Ferrari - 915-920 BHP
Mercedes - 915-920 BHP
Honda - 910-915 BHP
Renault (wide angle) - 900-905 BHP

Just estimated guesses, i'm not sure how much exactly.
(heard that Mercedes had around 920 BHP, BMW has the most powerful so must be higher and Ferrari can't be too far behind)

Hope it helps a bit...

[Glen]

I think Renault are still well down on the others, ASCII Man. Like 50bhp down. No-one ever gets to know the real numbers so it doesn't really matter so much, but I don't think anyone is much over 900, and most are in the 880 region. All based only on wht i've read, so could be complete cr@p!

[Robin Plummer]

What about Toyota and Ford/Jaguar any ideas?

[Robin Plummer]

930bhp from a 3.0 V10 thats 310bhp per litre!

I remember at the end of 1994 the Ferrari 3.5 V12 was kicking out 870bhp @14,500rpm and the Renault 3.5 V10 approx 820bhp how things have developed with higer revs and a smaller capacity!

[ASCII Man]

Mercedes had a major engine upgrade in August, which was reported to have over 920 BHP.

Toyota have a very powerful engine, somewhere in between the Merc/BMW engines, only the car itself is slowing them down.

Don't have a clue about Ford though...

[Dani Filth]

no way Ferrari V12 in 1994 had over 800BHP .. on their web site they only say over 700 wich is more beliveble

[ASCII Man]

I think i saw a BHP figure on Sato's Imola 1994 tape that Ferrari did have around 870 BHP with their V12 engine.

[Valve Bounce]

You guys are just pulling numbers off a dart board. I bet if I said BMW was pulling 940 because I heard it from Jack the bartender, nobody would doubt it.

[Dani Filth]

nobody would doubt you've heard it from Jack the bartender .. but about the 940 ... i would doubt it

[Robin Plummer]

I personally never belive commentator when they say in F1 that a team is 100bhp down on the others (such as they did with Renault in the past). Becasue in a car with similar aerodymanics and the same weight they would be a lot slower than 1 second a lap!

[Valve Bounce]

Well how do we explain the 3 second gap to Minardi? They must be running a V8

[Robin Plummer]

I can explain the Minardi gap. It is like my mates Mk3 Escort. The front brake disc's and pads are touching all the time slowing it down and making the discs glow. LOL!

[Champ69]

from f1 racing- July 03
Ferrari type 052 - 890@18.7k
BMW P83 - 900 @19.2
Imlor F0110M - 860 @18.2
Renault RS23 - 810@18.1
Cossy CR-5 - 860 @ 18.2
Cossy CR-4 - 810 @ 17.8
Cossy CR-3 Not much @ too much
Honda RA003E - 840 @ 18.1
Toyota RVX03 - 855 @18.4

but I have also read that honda think that they have the third most powerful engine on the grid but it is a bit of a anchore.

dont think they've managed to keep one together long enough to measure it, especially the one in the back of the Jordans, Pizzonia and Wilson have had a few problems as well.

[speedbump]

All I know is my Honda engine has 125hp

[Adam43]

...and blows up if you are a Canadian?

[ElScOrChO]

Anyone knows the torque of these beasts?

[speedbump]

No.
So far so good 265000km I just don't push it over 7000rpm down the straights to often.

[speedbump]

The torque must be incredible.
I wish I know as well.

[Splatz the Cow]

What?

No, the torque would be quite low.

The engines are only good at high revs.

My guess is 500 to 600 Nm at around 10000 to 12000 rpm.

Ah! That must be Villeneuve's problem, pushes it over 7000 too much!

I was just waiting for the JV comment

Honda has been in the racing business for a long time.
Don't know the exact history.
They did F1 years back, back into F1, CART racing and now I think IRL.
They know what there doing.

Just thought that there engines should be one of the top f1 engines by now.
The BAR chassis may not help matters aswell.

Let's calculate the torque roughly. Assume an F1 engine produces 800 hp (equals 588 kW) at 18.000 rpm (equals 300 rps(econd)).

P(ower) equals T(orque) multiplied with the rotational speed, so P=T*2*pi*f. We want to know the unknown T, so T=P/(2*pi*f). Fill in the situation of above engine: T=588400/(2*pi*300)=312 Nm @ 18.000rpm. This is the torque at maximum power, so not the maximum torque! We don't know that value, so we'll have to estimate it. Usually for normally aspirated engines the maximum torque is about 15% higher than the torque at maximum power, so roughly an F1 engine has about 360 Nm.

If we assume that ánd we assume that the power at maximum torque is roughly 15% lower, so 500 kW, we can calculate an estimated rpm as well with the same formula. f=P/(T*2*pi)=500140/(358*2*pi)=222 rps. Times 60 gives 13.300 rpm at which maximum torque is reached.

F1 engines are far different from regular petrol engines, but give or take 5% these assumptions will hold some truth.
