How many t-cases do you see?

1,150:1!

Mikronized

oh my god... that's hardcore..

It'd take about an hour just to get from your driveway to your street!

crawler#976

ok,

let's assume 5.29 r/p

first gear on a W56 tranny is 3.95

and 3 stock t'cases @ 2.28 each

for a crawl ratio of 247 to 1, 109 to 1 and 47 to 1 crawl ratios- thats COOL!

__________

BUT,

add a 4.7 gear set in one t'case and it's 510 to 1

add two 4.7 gear sets = 1052 to 1

and the Triple 4.7 Crawler is: 2169 to 1

___________

But wait, we're not done yet!

how about triple 5 to 1 gear sets, and going to a R151F tranny at 4.31 for first gear?

that gets us to 2850 to 1

tooooooooooooooooooooooooooooooooooooo slowwwwwwwwwwwww

The customer shifters are going to extreme pain to fabricate.

Was the intended for a 4runner or a on-going joke
supporting the local 4x4 shop?

And to accoring to Crawler#976 excellent calculations
@ that gets us to 2850 to 1. It would be insane to place
so much torgue on the universals or drive lines.

Maybe it's time to break out the Insanity Clause.

Thought I might jump in and give more exact numbers.
Keep assuming 5.29s in the diffs.
given that the picture appears to be a R150F with two R1FA reduction housings and then a V1FA t-case.

stock ratios would give you:
3.83 x 2.28 x 2.28 x 2.56 x 5.29 = 270:1

with dual 4.7s:
3.83 x 4.7 x 4.7 x 2.56 x 5.29 = 1146:1

I assume you added an extra 1 in your ratio scott. I believe my second calculation is what you actually have there in the picture. To answer your question, I only see one...

If I put that in my taco I would have to mount the third stick in my bed

Here is the page, go to the very bottom. 3.83x4.7x4.7x2.57x5.29 for the final ratio of 1150:1

And since we can never get enough, check out the videos here. The last one with Marlin's red truck shows it moving, if you can call it that, at 1047:1. Cool. It could only be better if Marlin himself was anrrating, "Fifth geeeaaarrr, fourth geeeaaarrr, third geeeaaarrr, second geeeaaarrr, first geeeaaarrr, yeah!"

Nah, 1,1150 is a number you only learn about in really advanced math placement classes! :pat:

44Runner

HAHAHA, I knew I should have taken more math while I was here. I had no idea!

crash

Heck, I only have 2 t-cases and I am 316:1

lcopelan22

I don't know what "placement" math you tested into but where i come from it's 11,150.

That's pretty awesome! It looks as if all you need is traction, and you're good to go. I'd say slightly lower gears would be nice for over here in the east, but something that low would be useless due to traction issues with mud and slick rocks here in the east. Very impressive!

What's it going in...pics?

44Runner

I doubt it is going/has gone into anything. It is just for show...

85runner

In that case, Lets show it installed in my truck over some rocks!!!

ravencr

Traction would be the key, that's for sure!

I'm perfectly happy with my 151:1 (with the ability to go to 724:1 if wanted) and more than a foot less length. And I've essentially got three cases if you count the granny low as a 1.98:1 case multipied by a 3.55 first gear (7.05:1 overall ratio).

I'm dropping down a little. I actually found the 2.8 - 4.7 - 5.29 a little low. My dana 60s have 4.10 gears. I'm not about to change them. I think I'll llike the slightly higher gearing on the trails, but on the road... I'll be glad I have 2wd low.
