Message	Here's my unscientific "real world" observation. After I had a lightened crank pulley, lightened chromoly flywheel and SS driveshaft installed, my tach needle would "blip" much quicker up and down when I tapped the gas pedal. Now that may sound trivial at first, but I equate that to improved "throttle response." Now that I think about it, since the X axis on a dyno chart is RPM's, and NOT time, then the area under the curve would probably NOT be greater, as you said. I didn't have time to examine your references. I'm two minutes over the end of a thirteen hour shift at work. See ya!

Your argument sounds specious to me. - robo (sebring1970) 23:02:15 01/24/05 yes but the time it takes is - J4Play 03:56:47 01/25/05 true, if you're measuring power, but how does that - robo (sebring1970) 06:24:50 01/25/05 how long it takes to reach a certain RPM will be a - J4Play 07:43:19 01/25/05 but how is what you describe represented on a dyno chart? (n/m) - robo (sebring1970) 17:42:37 01/25/05 how else is torque measured on an intertial dyno? - maglito 01:05:56 01/26/05 no, you would have lower peak HP/TQ also. Because ... - ScubaSteve 09:39:16 01/25/05 yeah, more energy to START a heavier object turning, - robo (sebring1970) 17:45:43 01/25/05 i still havent seen a comparison between oem and others - Chris(NJ) 06:47:40 01/24/05 yes. search for my post from 4-5 years ago regarding the CF - Bernie (OOParts International) 15:34:04 01/24/05
