Cruising at the peak tork rpm gives the best miles per gallon.

 

I drag race a 10 second 1987 Buick Grand National which uses a 231 CI V6 with a PT70 turbo, so I agree with this.

There's another saying: "Horsepower is how fast you hit wall; torque is how much of the wall you take with you."

 

Used to have an 01 Lightning that was pushing 17psi. I wish I had a GN. Found one local for 8700, but it's a bit rough, lol.

 

Just imagine how much faster it would have been if the 17LBS of boost was on top of a 7 litre engine instead of 5 litre engine.

 

Actually, how much of the wall you take with you will be based on your kinetic energy. Speed + Mass.

HP and Torque are intimately tied. HP = (RPM * Torque) / 5252.

 

Torque and engine size mean nothing! (Almost)
1. How fast you can go from traffic light (or quarter mile)
The only power matters. 2 bikes of the same weight will drive with the same speed if power is the same!
That means that if you have 2 liter engine your RPM can be twice less than 1 liter engine bike and power will be the same. It is very simplified explanation.
The reason riders like big engines is because they can feel their asses going into seat at lower RPM.
86 Kawasaki 250 Ninja has 14000 RPM redline and it is very light bike so it is pretty fast. Question is at which RPM rider will release clutch.
Only high power will give you good quarter mile time and highest speed.

 

That's really not the context of the question or the statement, and you know it.

Give me a 5.0 with boost and I'll make just as much power as a 7.0 without. The point there being I just made the same power with less cubic inch. Keep it in context, lol.

 

Harley started with a horsepower priority, switched to a displacement priority, and ended up with a torque priority. How's that for covering all the bases? The emphasis went from speed to power to smooth operation.
