i am pleased to see that 4th got a bump, while 6th (and 3rd) remain effectively the same.

the bump to 5th I don't know what to think - the old 'top speed' was at the top of 5th, right?

So now either:
A) top speed will be lower (at the top of the new 5th)
or
B) top speed will be in 6th somewhere.

Not that i really care about "top speed"; I'd actually prefer more acceleration in 5th between the two choices, but now the quoted drag limited figure in the magazines might go down - i wonder what people will think?

regarding the bump to 1st and 2nd:
any ideas on what that will do to the 0-60 time? (stock VS stock)
- I guess it is OK for NA cars, but my hunch is it will be too much if you add any real power to the car.

whats important here is we get a cruising rpm in 6th gear at 70mph that is the same as the old car, so we shouldn't see a loss of hwy mileage.

Jason, thank you for the data and secret8gent, thank you for the charts!

All of the changes look good to me! Shorter 2nd is nice, that should help out with lower speeds in 2nd. 3rd gear is almost identical, which is also fine.

4th now looks to be nicer/more usable on the hwy (and so is 5th).

Guys, make sure you post this information elsewhere on the site... I don't have the time to correct everyone who whines about the 4.77, and now that there's effectively no change in 6th gear, someone should mention that whenever someone _does_ whine. So, spread the word. Thanks!

before knowing the actual ratios in this new box there was a concern that 6th gear with the 4.77 rear would produce a decline in mpg.

not sure if someone else asked this... and forgive me for the possible "dumb question", but

Is the ring and pinion on the 09 the same as the 04-08? In other words, can I update my current R&P on my 04 with an 09 R&P and get the 4.77 final drive ratio?

so a mass produced 4.77 gear with mass produced prices that fits? This should be interesting for STU applications (Baggy, if you read this... this is an allowable update right?)

with those gear ratios and you blowing satans hairdryer, i would hope not. our current tranny ratios arent exactly FI friendly and the new one is even worse IMO

I wonder who will be the first to venture this direction. I will be EXTREMELY happy if it indeed works!!!

Was just searching for some info on what gear oil to use in the transmission. We bolted a 6 speed to our 12a bridged 1st gen this year, and have started having some issues with it after about 6 races. We were using just some syn. 80-90, but with the 7.25" clutch, I think the issues are more about the speed drop of the transmission relative to the motor (what Jason was talking about). We are on our way to Spokane for a double race and are going to try some Redline 75-90ns (wanted the 140 but couldn't find it locally). Took it for a lap up the street and it felt really notchy, but it was cold. Hope it helps. We have a cooler on the trans and it runs a consistant 180, just not happy with the shifting.

Yep, at least probably much cheaper than the FEED's 4.777 gearing set

jeff,

what transmission are you talking about? as this thread is about the 09 transmission..

making sure everyone is on the same page.. if you want info on the redline ns oil. you might search teamrx8. he has posted a bit of info on it..

and good luck!

beers

So if I'm in the market for an 08 or 09 RX8 for a daily driver with track toy privileges, perhaps I should hold out for the 09 because: 1) stronger transmission all around, 2) 4.77 final drive for a little better in town grunt?

Thoughts?

09 in 04-08 RX-8 Rrevs @60- 2nd - 8358 / 3rd - 6065 / 4th - 4353 / 5th - 3698.5 / 6th - 3077

All in all not a big change RPM difference wise. I don't have a feel for what that would translate to in acceleration numbers.

Mazda needs to re-think the 5th and 6th gear ratios as there is no need for anyone to be doing heavy acceleration on these two gears. These engines have a bad enough reputation for fuel economy as it is. My Fc and Fd run at 3,000 rpm at 75mph and get 27mpg on the highway.
I'm intrigued by the possibility of a more robust transmission, along with the prospect of a slightly taller 6th speed for use in my 2004; but, I'd hoped for a top gear ratio closer to what the autos have, so unless my transmission grenades out of warranty, I don't think this is going to be the panacea I'd hoped for.

Tangent: does anyone build RX-8 6 speed manual boxes with custom ratios?

Hmm I see they sell this 5.125 rear diff gear ... this is good for NA ... but once you go turbo/Sc this will be completely useless.

one is seals for rotor

other 2 is the gear ratio change.

Damn 5.125!!!!!!

Also, biggest upside to mazda oe FD is keeping my 100k warranty on my tranny that will eventually lose the 4th gear syncro.

I'd love to throw in the 5.125 and lose all possible highway mileage though lol
Out of curiosity, know any way of ordering?

Consider it handed

At around US$2,500 for the 5.125:1 Part; I doubt there will be many takers...

The FEED 4.77:1 crownwheel and pinion set is here:

http://www.japanparts.com/db/partsli...ey=226-009-021

226-009-021 and runs around US$700 ( with our RX8CLUB discount applied ) + Freight

One of our best selling RX8 Parts; we've shipped these to several countries, and ( of course ) these are for the *earlier* Models, not the '09!

Yep, who the HELL will buy that , not for 2500 bux lol !

I will consider that 4.777 gear when I reach 60-70 K miles, by then it should be a good time to take it down and replace some worn out stuff inside plus this new gear
