Is More Flow Better, Is The Smallest Intake Port That Flows The Most The Best
rocket engines produce thrust by the expulsion of an exhaust fluid that has been accelerated to high speed through a propelling nozzle.... ant got nothing to do with a 4 stroke internal combustion engine....DWB!
Thrust is a force the same as torque is force. Thrust is not "one rotation", just as torque is not "one rotation". That was the point of my analogy. But we're all good now.
P=fv
V is analogous to rpm.
More revs will always produce more power, all things equal.
Combustion engines produce a range of torque over the rpm range.
A "torque" engine tends to produce more down low and less up high.
A high revving engine tends to produce less torque down low, but makes the same or more torque at higher revs.
Power=torque*revs. Half the revs takes twice the torque to come out equal. Show me a "torque build" that ever doubles a race combo. Yet race combos often run twice the rpm of so called "torque" builds.
All the equations always support the higher revving system making more power, accomplishing more work, or reaching a faster speed within a set time or distance.
The high revver wins the drag race every time because of this.
This t'aint hard. No need for rockets or any other tortured analogies.
Torque is great, but without rpm you have a dumptruck. Sure, it'll get to 25mph in a hurry, or from 25 to 50, but then it's out of steam (power).
rpm = v because torque has a rotational vector. But again, torque is the force that moves, and rotation is simply the vector (direction) in which it is applied.
It's a bit disigenuous to suggest that a high-revving engine is not also a "torque" engine, because the more torque you make at those revs, the more power the engine produces. Hi-revving engines that have little torque down low have lag, are pigs to drive on the street, and the narrower the power band (torque curve) the more gear changes are required to keep the engine on the boil.
I honestly don't see what is so controversial about reiterating the fact that torque is the force that moves the car and that higher torque at any given rpm = more power. A flat torque curve is very much an asset on the street.
Because not everyone wants "more power" at the sacrifice of driveability. Maybe you guys do, I don't know?
I hope they all build junk with a TQ curve that’s higher than the HP curve and then be disappointed in what they have.
I built exactly that. A 408 with more TQ than HP, a flat TQ curve from 3500-5300rpm, changes gears at 6500rpm, has posted 11.6 at 121mph in a 3400lb car and is fun to drive. You can drive my car anywhere. I drive it to the track and drive home and touch nothing except the tyre pressures.
I'm not at all disappointed in what I have – I've got exactly what I wanted. Not everyone wants to drive a peaky pig with all its power above 6500rpm just so they can have bragging rights.
But I get that some people do.
