Ok, post 258. Lots of torque curves drop quite rapidly and it does not matter. IMO, dragging the torque curve flatter, longer means you are out of induction. That’s not a good way to make power.
Part of my point was you can’t just manipulate torque (especially above peak) and not hurt horsepower.
Which, BTW may be calculated but again, you can have all the torque you want and have zero horsepower. That’s not good is it?
No matter what, you have to have RPM. Otherwise no work gets done.
Show me any performance calculator that uses torque and I will renounce every word I’ve ever said about horsepower.
