man i want this sooo bad
|
I am in Dallas, Tx.
This is a direct swap. |
It prob be easier to just swap diffs than the gears alone. plus 4.77 could be for racing, and stock for street use... If i had money id be on this.
|
well im guessin he wouldnt want my 4.44 gears
|
Would this fit on a 2004 AT rx8? I assume it would
|
i'm confused now. i'm finding a new one from mazda for a grand.

I think that may be for just the ring and pinion?
what sort of gains should i expect? |

hmm. interested. i got a quote to put it in. mazda says 6.5 hours, but it won't take that long. i figure i can get it put in for around 350.
what sort of gains should i expect? |
Yes, there will be no power gain. You will just have a little faster 0 to 60 time.

Youre not going to gain anything. The car will rev up faster in gear so your top mph for each gear will be lower but it will get you up and moving faster.

that counts as a gain. i wasn't thinking hp gains. i meant what exactly was the overall benefit. and this was answered nicely. i had sort of a vague idea about why this would be good. now I know exactly why. so thanks.
and i'm still interested in this. |
On a stock tire RX-8, the difference at the top of 2nd gear at 9k rpm is 68.84 mph versus 64.07 mph with the 4.77 gearing.
Mechanical leverage (torque) goes up by a little over 100 ft/lbs at the rear tires. Yes, I am anal enough to have built an entire spread sheet which calculates this, taking into account everything down to exact tire circumference. :) |
