Subject	I'm not so sure. Your argument sounds specious to me.

In Reply To	what if the flywheel weighed 200lbs instead of 27lbs ? posted by ScubaSteve on January 24, 2005 at 12:49 PM
Message	For example, if you hooked up a million pound flywheel the engine obviously wouldn't turn - 0 HP, 0 torque. But once the flywheel weight got light enough such that the engine could turn, then the max HP should still be attainable, it would just take longer to reach it. Since dyno curves do not measure time (the X axis is RPM's) then the dyno curves would be very similar at most "realistic" flywheel weights, or drivetrain weights.

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
