Hey folks, if you haven't heard there is a company that may be willing to make a tall 5th gear for the t50 trans. This would allow you to have a 4.77 rear end and still have under 4000 rpm while cruising at 115km/h or so.

This was ready to go into production but some trouble with the earthquake in Japan has made TeamMfactory a little bit uncertain about going through with the production.

Here is the original thread:
http://forums.club4ag.com/zerothread?id=74956&page=1

Please, if you think you would buy this gear at a price of $350 USD PLEASE send Patrick an email expressing your interest.

pcseto AT teammfactory DOT com

I think that if he gets enough interest from all over the globe he will be less worried about being stuck with 10 gears. 10 gears is all that is needed to be sold for this to be a success.

Thanks,
Grant

PS, I apologize if this isn't the best location but I wasn't sure where else to put it.

both myself and delazy expressed interest at the time, but as such he was short on numbers at the time.

havent heard anything since....


FYI this longer 5th gear is really only useful if you using a 4.7 final gear as it would bring the RPM BELOW 4000rpm @ 110km/h, instead of 5000+rpms.

Calculator gives me 3,500 rpm at 112kph.

I can't stress enough that this might not go through if Patrick doesn't think people will buy 10 or more gears. Please email him if interested.

LOL! 4.77's sit on barely 4000 @ 110.

whats the original 5th gear ratio?

and what is a real figure for revs you would sit on with this gear?

Stock 5th is 0.86.

Speed in gear 1-5 stock 5th @ 8000rpm - (top speed w 0.773) - RPM @100klm/hr 0.86 5th - (Rpm @100klm/hr 0.773 5th)

4.33:1
57-100-146-203-236 - (262) - 3380 - (3050)

4.556:1
54-95-139-193-224 - (249) - 3580 - (3200)

4.77:1
51-91-133-184-214 - (238) - 3750 - (3370)

5.4:1
45-80-118-163-189 - (210) - 4250 - (3800)

Looks like a good idea for any street driven rig with 4.5 or better.

you sure? the site still lists them (tho doesn't say the ratio)

http://www.revolver-jp.co.jp/products/drivegear.html (Over Top Gear 42,000yen)

And xero, I have a 4.7 final gear and 5th gear @ 110km is just below 4000rpm with a standard box and 205/50r15 tyres.
dunno where you're getting 5000+ from?

I know mine has a 4.1 and sits at 3,600rpm at 110km/h. With a t50 and 195/50/15. So I can see that a 4.7 is going to crank it a fair bit higher.

4.777 / 4.111 = 1.1622 (yes you can do this as its the ONLY variable changing)

3600 * 1.1622 = 4183.78rpm @110km/hr

Which is pretty much smack on with me. with 185/60/14 (pretty much same overall rolling diam. as 195/50/15) and standard t50.

My zorst is actually really droney below 3500, so my car actually got MORE bearable with 4.77's than with 3.9/4.3!!LOL

to give you guys more accurate. 860 ratio drops about 500 revs every 3500 so at 7000 it is 1000 revs if final 5th is. 880 its about 350 revs or 700 over all so .737 will be about 600 to 700 revs and about double this at 7000rpm

.886 trd ratio 3950rpm and .737 is 3200 rpm
this is at 100 kays per hour or 63mph

Albins here in Oz will make any ratio you want for 5th, they would have no trouble making a custom ratio like you guys are looking for. They will make a full custom gearsets for a T50 in any ratio's you want except 4th which has to be 1:1. They are very flexible on making custom ratio's and can do the same as a TRD gearset etc.

From memory they will charge $350 per ratio so the same price as the gears your after, they will discount the price if several of the same ratio are made.

Yes, these are being made!

Team MFactory is making them, there should be a physical product in a couple of months.
