1.15 to 1.25 tq are average guy fully built engines gross dyno #. For a less efficient engine probably gonna be under that like 1-1.15 tq so like 1.08 tq average, really if your good at guessing peak tq and powers peak rpm, just need to 0.9 x tq x rpm / 5252 = hp, say a 440 makes 470 tq and hp @ 4500.
