Message	I can't see any way gears can increase engine HP, but I guess they could more effectively transfer the existing engine HP to the ground? How does that sound? Any physists/engineers wanna explain?
Follow Ups	ok on those 4:10 richmond gears ...I never saw a dyno with / - Andrew(nj) 05:34:53 08/23/07 I gained 6-7 MPH On my trap speeds with the 4.10s.

(n/m) - Octavian 08:07:39 08/23/07 but you would still run the dyno in your 1:1 gear (n/m) - Atl300zxTT 08:12:16 08/23/07 1:1 at the trans, the final gear ratio is still different. (n/m) - spyhunterTT(nj) 10:03:51 08/23/07 thanks for the clarification (n/m) - Atl300zxTT 10:30:16 08/23/07 indeed - aliaZ 08:58:27 08/23/07 Re: indeed - GPA 10:00:45 08/23/07 For a fixed driveshaft rpm, the rpm of the axles goes down - 300zx90 (CO) 10:22:16 08/23/07 Horsepower is a derivative of torque, so - Octavian 10:02:31 08/23/07 This is getting deep..... - GPA 10:06:30 08/23/07 LOL, you are not making 50hp with the gears. You are - Inzane 10:07:52 08/23/07 LOL, I know, but its odd that the mph go up because - Octavian 10:19:15 08/23/07 Good point. However it could be that w/ the gears you spend - Inzane 10:30:23 08/23/07 Basically, I believe the Leader Gears make more efficient - GPA 10:33:20 08/23/07 yep (n/m) - aliaZ 10:43:49 08/23/07 Less time to accel, but your accel-ing at a higher rate. - John B.

(n/m) - GPA 19:25:10 08/23/07 Clarify: - RSR 07:56:01 08/24/07 please read up on inertia dynos before posting this stuff (n/m) - ztunerz 12:47:38 08/23/07 Correct info, incorrect explanation - ZCulture 12:39:17 08/23/07 yes, but it depends on the point of reference - aliaZ 14:39:17 08/23/07 Re: Gears are a torque multiplier. - Kenny 09:09:46 08/23/07 werd.
