car was COMPLETELY stock when i bought it, and i checked the code on the diff tag a long time ago. it was 2:73, but i'll have to go count the teeth i guess. At 120km/h, in 5th i'm about 600 rpm's higher than before.....
thread back from the dead! i am happy with the swap. I know the accelleration is improved, but i think i was expecting more of a 'snap' when i hit it, i think its because its a smooth accelleration that i'm not getting the punch i expected.....
unanswered question: if i'm at 2400 in 5th (at about 75 mph) now with the 3:73's, and was at about 1900 before, were the old gears 2:73's or 3:08's????
ok so i just did some math, and i think that makes the old gears 3:08's???? this makes no sense to me because the diff code came back as 2:73, so who would swap 2:73's to 3:08's on an otherwise COMPLETELY stock car??? ideas?
Okay, I just read about 5 of the posts on here, and got tired of hearing that you're supposed to break-in gears. IF your gears are installed correctly there is NO break-in period. How many nascar stock cars do you see "breaking-in" their freshly installed gears driving up and down the street calmly and gently. Or how many funny cars do you see making grocery runs, etc.
Even if they are installed incorrectly there is no break-in period, they're going to get f'ed up no matter how you drive it.
Get gears installed professionally and drive it how you want. That's it.
I know this is a huge debate and this won't end it, but I just had to say it.
Getting back on topic now:
As far as being dissapointed; If you actually noticed the difference for the better then it worked. If not, then you either chose the wrong gear ratio or you're driving your car differently.
I went from 2.73's to 3.73's and noticed a huge difference. You're old gears should actually have the ratio stamped on them.
HP is what spins the tires, torque puts the HP to the ground, gears are torque. You don't get a lower gear ratio to spin the tires, they're designed to get the power to the ground and get a better launch off the line.
Can someone supply some info from a gear vendor stipulating that no break-in is required. At that point I might change my thoughts (though probably not since a break-in hurts nothing).
We're talkin about street cars that will have this gear for hundreds of thousands of miles here, not track cars that receive hugely expensive (and treated) parts which are inspected/replaced constantly.

Have any of you ever "broken in" gears on a brand new car???? Doubt it. Same thing, isn't it?
lets start with this question...how useless is 1st at wot now?
