Best way to test performance gains from a change in final drive ratio is a 3rd gear running pull. Get a buddy to drive with you before and after the gear change and time a pull from 30mph to 80 mph. You'll see the advantage of gearing changes in the real world that way. This is also a way to see the advantages of the ap2 motor/trans changes as far as acceleration is concerned.

NOOO! That "test" takes advantage of all the strenghts of the geared car and none of the weaknesses. At low speed in a high gear the geared car will STOMP a stock car b/c it has both a gearing advantage and it will reach peak power sooner. It's the same reason an AP2 will kill an AP1 if you go from 3rd gear at 10mph. If you're going to do a roll comparision start both cars in VTEC or it's completely pointless.

I agree. New gears give a mechanical advantage in 1st gear only, then the extra shifts will even the playing field with a stock car. As a perfect example, the gear changes AND bigger engine in the AP2 didn't make it appreciably faster. People just want a 'quick fix' to make (at least in their head) their car faster. Unfortunately, more power and less weight are the only solutions.

I'm not sure where you got this information...but it is incorrect. Have you ever driven a stock AP2 and one with 4.56 gears??? Judging by your post...I would say "no".

First, I'm not sure what you mean by a 1st gear only "mechanical advantage".

After you do a 4.56 gear swap in an AP2, it almost renders 1st useless. The RPMs pick up so fast you need to be a fast shifter to take advantage of the speed. With stock gearing, an AP2 drops out of VTEC shifting from 1st to 2nd. With the gears...you are now able to stay in that sweet spot and build more power. Again, you need to shift at a much quicker pace then a stock AP2 to maintain speed.

This is not just a "quick fix" or something "in my head". My car is faster then it was in stock form and builds power quicker. I have proven that over and over to many stock AP2 owners. However, I didn't do the gear swap to make a quarter mile machine. I made the change to help my car hit VTEC and it's power band quicker. This swap really helps when tracking and hitting the twisties. If you lived closer to me, I'd take you for a ride. That way, you will see exactly what a properly driven geared AP2 will do.
