3.308
 

I already posted on Bill's Facebook. I really hope he can get 15 in on this deal, and that it goes this time. My car would finally be complete with a set of 3.308's

Hmmm

holy jesus fuck do want!

In.

If you're in, tell Bill Wilner via his face book, email... He said only 15 needed for the group buy this time. Need everyone's help to make sure it's a go.

Already in touch with Bill. I may buy a few sets and put them on the shelf if he gets close but can't bridge the gap. If that happens, the markup won't be small, so get yours now :)

If I didn't already have a 3.63 waiting to go in I would definitely be in. How much power do you need to put down for this to be faster than a 3.63 with a 6 speed? I imagine it is a lot considering the 3.63 needs something like 300rwhp before it is faster than the 3.9 on the track, correct?

I have money to throw around. I have an stock engine 01 with a 3.9 and a mildy modified 04 MSM with a 4.1. What will this 3.308 do for me? Will it help either car?

I checked the FB page. He has no source for speedo gears, so track only if you like an accurate speedo. He also said he will make a thread here once it is official.

I spin in 1st, 2nd and a lot of 3rd. If it's a choice between being able to put power to the ground and speedo gears, I'll pick power any day. If I have to, I'll get a GPS speedo (or just tape the popular speed limits over my current speedo, lol)

I have 3.63s in a diff already. Still buying 3.308s. This will probably be the only chance you ever get to buy them.

I'll take two (2) sets.

I'm in!

MiataRoadster 3.3:1 R&P GB teaser
 

Well, so much for a tease on FB…the cat's out of the bag now.

:party:

My plan is for a 3.3:1 R&P to become an on-the-shelf MiataRoadster catalog product that, after the initial GB, will be readily available at a higher price point than the GB. I will have an exclusive on it with the manufacturer and I'll be happy to talk wholesale with dealers, if any are interested in carrying it.

To make it happen initially, the manufacturer needs 15 paid-in-full orders to amortize setup costs. There would be a 90 day turnaround time for the first batch to come in, then there would be a constant availability.

From the response to the tease on FB it seems at least the 15 takers are out there. Of course, we'll see how many actually put their money where their mouths are.

I'll start a GB thread soon when I'm prepared to accept orders. In the meantime, feel free to contact me to express interest at Bill@MiataRoadster.com.

I hope we can make this happen, as some of you are aware it's been a pet project of mine since at least 2008.

Thanks for your interest!

Bill

If you guys are super worried about speedometer, would something like the YellowBox not work?

https://www.miataturbo.net/attachmen...ine=1384096450

Official home page of the Yellow Box Speedo Recalibrator

It would. I was thinking of designing such a thing, didn't know it existed already.

Yellow Box only works with electronic speedo/odo on NB/NC, won't address issue on NA.

I'm sure there will be a random source or something that can be hacked together to make the correct speedo gear. Its just a freaking little piece of plastic, there's probably a hobby gear that only needs the inner hole changed with a dremel to make it work with the sender.

Whats the chance that these are going to be stronger than the stock gears? People are going to see this who were going to the 7.5 or 8.8 for the ratio and the strength and would come back to the miata diff if they could get both. If the gears are stronger you can make everything else in the rear end stronger with the crush sleeve eliminator, MSM OSG, and MSM axles.

ABS plastic from a 3D printer would probably not be stable enough in the elevated temps in the gearbox. But who knows, it might work.

A speedo gear for 3.6 will not be very off (it will read 9% low).

My "3.6 speedo gear" reads 10% high as it is...hmmm

I wouldn't ask for your money and sell you junk.

These will be "race" caliber parts, made by a reputable manufacturer.

(That means better than stock gears.)

Who's the reputable manufacture?

No, Erat, that's the actual Name of the company "A+ Reputable Manufacturing"

This would be preferable to the 3.63 for me. I'm in when you start looking for $. I'll probably see it here before fb.

The manufacturer will be named when I post the details about the GB.

Thanks for your patience!

If there's one thing I know about Bill, its that when you buy one of the MR products, you're not just going to get that product, you're also going to get every part to install it, and then some other parts that go along with what you bought that you have to look up what they do because you had no idea that you actually wanted them, and you'll end up with a small tube of more loctite than you'd ever need to do the install. So knowing bill, the R&P kit will come with new diff bearings, a tube of grey RTV, some loctite, all the seals for the diff, and a crush sleeve eliminator kit, along with a few parts I didn't even know were in the rear end even though I've had a bunch of them apart and swapped ring gears before. :p

I'm guessing that Leafy is referring to the shifter kits. Thanks for the kind words, but the differential is, well, different.

I can't offer "crush sleeve elimination" as part of a kit because that's a specialized machining process where the machine shop has to have the actual pumpkin and gears in their possession to create a solid spacer tube. I can refer people to a respected colleague of mine who offers that service, plus others including reinforced saddle caps.

The following will be explained in more detail when I formally announce the GB, but my plan is to offer people two kit options: "Basic" and "The Whole Enchilada."

"Basic" kit would include the 3.3:1 ring and pinion, a crush sleeve, and a pinion nose nut. This would be for people low-mileage differentials where they are confident that their bearings and seals are reusable.

"The Whole Enchilada" kit would include all of the above plus (4) bearings and (3) seals. All of these would be genuine Mazda parts.

I can also arrange WPC Treatment as an upgrade for either option: WPC - Metal Surface Treatment / Micro Shot Peening

FYI, cryogenic treatment is not recommended by the manufacturer because the gears will be heat treated.

Thanks for your interest and patience!

Weir performance already makes the crush sleeve eliminator for our rear ends. So no need to have them custom made. They get around the custom part by having a basic solid tube made and having shims.

Thanks for the tip! I'm going to set up as a dealer for those and I'll make them part of "The Whole Enchilada" kit.

Just found out that I can adjust my speedo calibration with my Hydra.

A simple GPS device should take care of the need for a speedo. Or just tape numbers like O5pearl suggested, haha.

:yippee:
Was looking into doing this myself...easier to give Bill $.

Yeah I'm probably going to end up getting a set of these since they make the 6 speed gearing make sense. As much as I didnt want to spend this kind of money this year.

Get Adam (revlimiter) to make a customer set of gauge faces for 3.3 gears. Done.

Odometer will never be right.

What Savington said. Even if it was possible it would be difficult to make to scale and it would look really weird because it is a percentage scale not a fixed amount that it would be off.

Excuse my ignorance but why would someone want these gears? I know with 4.10's I use 3, 4, 5 & 6 on the track. Would I then use 1, 2 , 3 & 4?

Are you trolling?

If you're cruising at 80 on the highway would you rather be at 3850rpms with 3.90s or at 3250rpms with 3.30s?

I have to think above 300whp you're going to pick up some significant overall acceleration compared to stock gearing with a 6 speed. 3.90s are great with 100hp, but as power increases you're really rowing though the gears. Maybe it's different for all out track cars, but these seem like a great idea for those of us who spend most of our time on the street.

Of course not it was a serious question.

See for yourself: http://www.grimmjeeper.com/gears.html

I just want all you knuckleheads to buy 3.3s so that maybe I can get into a set of 3.6s on the cheap. ;)

:loser: I only use 2nd gear with the 4:10. But with these gears I could use 2nd gear of a 6 speed and run ALLOFIT.

all this talk of allofit when bob keeps popping 6speeds on track with a 3.6 and 350whp lol....in for lots of broken 6speeds

but I'm seriously tempted to get these......ugh

I'm building a list to see how many sets people want so far.

So I can cross-reference between real names from Facebook and silly forum names here and get an accurate count, please email me @ Bill@MiataRoadster.com with: the # of sets you want, your full name, shipping address, and phone #.

Details will be announced formally later this week.

Thanks,
Bill

^ Done

I forgot to ask, please state your silly forum name when you contact me so I can cross reference who's who!

emailed with my silly forum name

Let's go everyone!!! I want my 3.308 gears!!!

emails sent

I think for me it would only help first and second gear for street driving and maybe autocross. on tracks it would make 6th gear not so useful I think. My car on some tracks would like the 3.909 and others like the 3.636. I think to really use 6th with the 3.308 you would really need over 400rwhp to push the speeds achievable. The hp needed per speed starts getting real non-linear in the 140 to 160mph range, gearing the car to go 180 is not going to make it faster. I also don't care about highway cruising gear.

the 3.308 to me is interesting because it might make some other transmission work that might be light and strong. I don't know what one that would be however. The stock six speed has 4 track useable gears I would be slower with less. A 5 speed Jerico maybe.

I'm pro 3.3s because I care about cruising speeds and rev'ing past 4-4.5k while cruising is plain annoying and pointless....bringing that entire range down ~1k would be amazing and make the car a more livable vehicle. (I have 4.10s now in the MSM)

Do we know what the group buy price difference is going to be? Thats what stopping me now. I dont have any need for these gears until next off season, but if the price difference is going to be significant I'll buy them now and sit on them.

Leafy, it is on the FB link.....
"MiataRoadster tentatively, $525 + $15 domestic shipping = $540"

Maybe one day we'll see a 1.6:1 ratio...You can't blow up 4th gear in a 6 speed if you're only using 1 through 3!!!

Yes, but what will the normal price be.

Perhaps there are uses for a Miata not on a racetrack.:idea:

Yeah, what makes this R&P attractive to me is that it would let me drop in a bolt in tranny solution that can take 300ftlbs reliably and end up with a 2nd gear that makes sense.

I know it sucks to have to cough up $540 for a lot of people. Believe me, I don't want to sink any more money into my car, but I'm going to do it for these gears. Leafy, I know you want to wait, as well as others. But, if Bill can't get 15 people on board - no one gets any 3.308s - EVER.

For me, it makes entire sense throughout the gear range. I can take off from a start without spinning and I can cruise on the highway at 3000 instead of 3800. As I said, this would truly complete my set up for what I want out of the car - a fast, sleeper street car, powerful with great handling.

I'm begging you guys - whoever is serious about getting these, please get them now. I don't want to have to do some huge hybrid trans swap in the future to be able to do what these gears can do for me, for a LOT less time and $$$.

If you are that deep into plans, get two and sell the extra one later on, to make sure the project gets rolling.
You will probably not loose more than $100 (if you will loose at all) reselling a new set.
