Default 4.44 final gear vs. 4.77

Which is more street friendly, and what will the S2000 top out at with both of these?

The 4.77 would not be highway friendly, but would be fine around town, and the 4.33 would probably be fine for street or highway. Assuming top speed is around 155 MPH with stock gearing (4.10), the calculated top speeds for 4.33 and 4.77 gears would be around 147 MPH and 134 respectively. I didn't calculate everything down to the n'th degree, but these numbers should be relatively accurate.

hmmm...decisions decisions....i'm assuming you made a typo and you meant the 4.44s top out at 147? Would the difference in acceleration be highly noticeable between 4.44 and 4.77?

What would make 4.77 not appropriate for highway use? Is it the high RPM's at highway speed, gas mileage or something else. I have been thinking about this mod and have been toying with the 4.77. Thanks for any info.

Go to The Reverend's garage (http://reverendsgarage.net/index.php?conte..._calculator.php), where you will find a really nice gearing calculator. Using this calculator, you can see that 6th gear with 4.77 gearing will be about the same as 5th gear with stock gearing (4.10). The 4.44 gears would be between 5th and 6th gear (stock). If you don't think it would be annoying to drive on the interstate in 5th gear (stock), then you should go with the 4.77s. Your gas mileage will decrease a bit, but probably not significantly.

BTW, it wasn't a typo about the 4.33 gears. I didn't know there was a 4.44 gear set available.

Wow.... a group buy would be awesome. Also IF your into quarter mile times and so forth i believe the 4.77 would require one more shift in the quarter mile. They both would require and extra shift to 60 mph. The extra shift in the quarter mile might add to your time enough that you'd get a time that is close tho the 4.44.

Also i understand that the 4.44 gear is about an 8% (7.7) reduction in size. Would this directly transfer to your times .....example say you run the quarter mile in 14 seconds
8% reduction of 14 is 1.12....so would you be able to run 12.88
I realize there are many variables but if you where to run the exact same run would you get a true 8% reduction....If so this mod would stomp on a s/c for bang for the buck. Ok Just wondering..........also wondering when the big "x-viper" is going to chime in....he has had his for a few weeks now....i am sure he has tested it to the limits by this point.........wow...the 4.77 is a 15%reduction.....Wow....if this translate to 15%of 1/4 mile times we are talking close to two seconds......oh my. i have no idea if these reductions translate directly to times so please and mechanical engineer types please chime in.

I remember hearing someone saying half a second on your 1/4 time with the 4.77. Hypothetically speaking...

It will not reduce your 1/4 mile times by 8% or 15%. It would be more like increasing the amount of power by 8% or 15%, which we all know is not going to improve 1/4 mile times THAT much. You will still be limitted heavily by your launch and gear shifting.
