19 kwi 2012 · The steering wheel is right around 10" diameter so 267 in-lbs would be 27 lbs per arm (one pushing one pulling). The important thing here is that this is generally just during turn in and then quickly falls off during steady state turns. Generally the SS torque is ~100 in-lbs.
Race engines tend to have peak torque at or near peak power, so ~1000HP @ ~11000rpm = 647.4Nm for the 1.6L turbo hybrid. Or ~700Nm for 1000HP at 10000rpm. The 2.4L V8s had 350Nm according to Ross Brawn: https://youtu.be/9dr-Ixwy2XI
The following formula can be used to calculate engine torque: torque = (horsepower × 5,252) ÷ rpm. In this formula, 5,252 is the RPM at which horsepower and torque cross over on a graph showing the values at various RPM, assuming that the scales on both axes are identical.
Estimate Converter Slip. Wallace Racing BACK to Auto Math. In order to get a realistic value, use: Your finish line MPH (from ET slip) Your finish line RPM. Your Transmission Gear Ratio at Finish Line. Your ring and pinion (gear size) Your circumference or roll out of the rear tires. (not Diameter)
