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.

That is 393nm right? Much much more then I imagined.

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.

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?
