No problem about the thread jack.
I'm sure this'll be recreated in the kill section later.
Any bench racing discussion until then is fair game.
We got a high revving I4 in a light car vs a low tech, low revving pushrod V8 in a heavy car.
Their torque to the wheels, to propel the car, is up for grabs right now.
Fun fact about NASCAR is that they have the highest piston speeds in professional motorsport.
High stroke + high rev (9000+) = 'merican supposed low tech in the lead.
So there you have the big trade off in cars.
Usable powerband and application vs peak of performance.
Personally, I like a daily driver engine that I can 'blip' and take off.
Wringing an engine out for more revolutions only equals more wear vs an engine that can produce the same amount of torque to the wheels at lower revs.
If we're talking about track vehicles I might change my stance solely for the music a higher revving engine is capable of.
Then again, a track car should have one selfish purpose only.... the feel it gives to the pilot.
