Gentlemen, rate your engines!

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

I was reading CAR and they said after talking to several sources it looks like there is about 290 lbs/ft of torque in the V-8's.
Simon: Nils? You can close in now. Nils?
John McClane: [on the guard's phone] Attention! Attention! Nils is dead! I repeat, Nils is dead, ----head. So's his pal, and those four guys from the East German All-Stars, your boys at the bank? They're gonna be a little late.
Simon: [on the phone] John... in the back of the truck you're driving, there's $13 billon dollars worth in gold bullion. I wonder would a deal be out of the question?
John McClane: [on the phone] Yeah, I got a deal for you. Come out from that rock you're hiding under, and I'll drive this truck up your ass.

I'm a little skeptical about that. Those engines have a very short stroke and not conducive to high torque numbers. I'd reckon it's more around 210-230 at best. My 4.8l truck engine has that much torque with twice or more stroke.

The math does not add up. i would place the peak torque to be about 200lbs if that.
To finish first, first you must finish.

I understand that you are using F1 Championship, but rFactor has mods for 2006 and 2007, and they are quite good.

Maybe you could extrapolate from that.

As well for rFactor, there is a very detailed BMW F2007 mod as well that is the basis for their sim AFAIK.

You must remember f1 engines achieve over 100% volumetric efficency in your calcs. A truck engine will not.

In 2006 Toyota claimed their engine produced approximately 740hp at 19,000rpm. This equates to 205lbft of torque, so the peak torque figure must be slightly more than this, maybe 210-220lbft?
