RPM for all motors? If so, then beyond that RPM the motor only gains HP and must rely on said HP to keep accelerating? I'd think; /html/ba-autox/2000-01/msg00154.html (9,484 bytes)

Re: Rotary torque & noise (score: 1): Author: "Donald R McKenna" <donbarbmckenna@earthlink.net>; Date: Tue, 25 Jan 2000 21:54:23 -0800; My understanding is that torque and Horsepower cross at 5252 RPM in all motors (if they will spin that high). I think HP = Torque x RPM / 5252. Therefore at 5252 RPM they are equal. Most engines we; /html/ba-autox/2000-01/msg00158.html (8,650 bytes)

So, by your logic I will accelerate faster with 500ft-lbs at 5000rpm than 500ft-lbs at 1500rpm? -Andy Do Yo; /html/ba-autox/2000-01/msg00175.html (8,330 bytes)

This is definitely true, for example, if you look at many of Spoon's cars, they make identical peak horsepower to their stock counter parts... but they have much more area under the torque; /html/ba-autox/2000-01/msg00185.html (8,702 bytes)

Re: Rotary torque & noise (score: 1): Author: Andy McKee <andrewmckee@yahoo.com>; Date: Wed, 26 Jan 2000 11:13:52 -0800 (PST); Unfortunately, the peak torque figure is also "little".:-) I liked the one magazine test where they did full throttle acceleration with an S2000 and shifted at 5500rpm (instead of 9000), resulting i; /html/ba-autox/2000-01/msg00189.html (8,758 bytes)

Re: Rotary torque & noise (score: 1): Author: Andy McKee <andrewmckee@yahoo.com>; Date: Wed, 26 Jan 2000 13:59:49 -0800 (PST); Actually, I was looking for 1hp = 550 ft-lbf/s and 60 sec/min to get the 33,000, with the real question being where the 550 came from (typical English unit garbage). Two means to the same end. I just; /html/ba-autox/2000-01/msg00198.html (10,442 bytes)

I remember. The 550 is actually 552.59. 1 horsepower is 746 watts, 1 lb. ft. is 1.35 n*m. 746 / 1.35 = 552.59. and This is WRONG (though i; /html/ba-autox/2000-01/msg00204.html (12,517 bytes)
16. Re: Rotary torque & noise (score: 1): Author: Andy McKee <andrewmckee@yahoo.com>; Date: Wed, 26 Jan 2000 16:38:36 -0800 (PST); So how come it is 746 watts per hp? You're still missing the question. Unit conversions are fine and dandy, but I was wondering how 550 ft-lbf/s became 1hp. *snipping extreme Clements verbiage* Mike; /html/ba-autox/2000-01/msg00207.html (10,038 bytes)

That's why power determines acceleration, while Torque and RPM are equal contributors each of which in itself means nothing. Now let me take Katie's advice and provide a simple example.
