the factory speedo is off by a couple mph.
your personal opinions dont argue against the math.

the speedo is off a tad bit, so is the tach.

First off, to clear things up, i didn't mean to come off as a jerk or show disrespect to anyone. I just found it hard to believe of how much margin of error there can be. I appreciate all of your responses, as you did take the time to help me figure this out. So if i came off as a jerk, i apologize.
With that being said, my tire sizes were (new ones now) OEM, and i had about 32psi all around. I would still stand behind my figures, but if you guys are saying the factory speedo/tach is a little off, than i guess my figures don't matter.

yeah, that burnout must give you that extra 1mph...
can you step outside of the box you are in and try to comprehend what you just said?
my figures arent wrong, and i'm glad i wasted the time to map them out for you with that kind of response.
p.s. - if you are burning out - that means you have no traction, thus you aren't accelerating.

Doesn't anyone here have trap times, or something to give us a better idea of what kind of performance 4.57/4.77 gears will give?
Common now...
I agree with Spec_Ops. Everyone's experiences will be different.
However, if we had a set of 5 Quarter mile trap timeslips to compare, all stock S2000s with 4.57 gears... we could average out the 1/4 times and at least get an idea of the performance gains.
Sure, there's ENDLESS variables to consider. But we can all agree that a stock S2000 can almost never break a 13.5 in the quarter (right?
).

A perfect scenario would be:
"MemberXYZ took his S to the track, in stock trim. Ran 3 times and here they are: 13.9, 14.0, and 14.1"
"Then, MemberXYZ had 4.57 gears installed. He went back to the track and ran 3 more times. This time he ran 13.5, 13.6, 13.7..."
Whatever... you get the point.
This helps to gauge performance increase because you reduce the effect of some variables such as weather, driver skill, tires, track conditions, etc.
REDUCE... not eliminate.
But, in tht scenario we could gauge that MemberXYZ increased his performance with gears by around half a second in the 1/4 mile.

it really just depends on how fast you can switch gears because you'll be switching more with 4.77's 1 extra gear shift can significantly make a slower time. im heading to the track with my 4.77's to see what kind of difference ill post time slips asap. i chirped 4th with the stock gears. i recently chirped 5th

I wish my stock clutch held up that well. I can't get the clutch to grab hard enough on a 3-4 shift or 4-5 shift without overpowering it. When you're shifting are you staying in VTEC or dropping right below engagement? I shift at around 8400-8500 so I've got a few more horsies on tap than you do when I reenage for certain. I definitely overpower my clutch before my tires. Maybe my clutch is significantly more worn than yours, cuz I know these tires aren't particularly grippy.

Different day could make all the difference. You'd have to find a day that has approx same temp, precip, sunlight, amount of that sticky compound on the track, same line up area, the driver will be slightly different, etc etc etc....I could keep going but you get the idea
Its not like you could go to the track, install the new gears the same day, and go back later in the day. The gears need to break in.
Point is, best way to decide is to get a ride in a geared s2k so you have something to compare your stock to
