Idaho BS thread in the PNW

I just did some more math and 4.88's would put a 40" tire into my stock rpm range. haha.

It will be cool to see what my acceleration looks like after this Although the locker may not be enough to keep both tires from breaking loose with those gears. haha.

 

Before i bought the taco i was looking for a 4runner but couldn't find on i liked and this deal was too good to pass up. even if i return it to stock sell all my accessories then sell the truck for 14-15k I'm still sitting pretty.

I think you would be significantly higher, like 3300 with 4.88's. It looks good on paper, but go put a tape measure to your tires. I bet they measure out to 32", maybe less. I have 4.88's, come put your tires on and we'll go for a ride. I bet you'll change your mind. I vote for 4.56, then you can get the thick gears and don't have to change your carrier, unless you plan on getting an arb up front in which case I say go 4.88 but get bigger tires.

 

lol just do it! don't think anymore haha

well your UCAs, and front coils/shock i think can transfer over to a 4 runner..doubt the bumper then..could mod the roof rack to make it fit. lights you'd keep and the winch.

WHo knows maybe the bumper lines up lol

either way, im sure you'll pick a sweet ride. Just don't forget about us

 

i'll keep it in the family the 4r and taco are kissing cousins

 

Yeah that is all on paper. And I did measure my tires the other day and they came out right at 33 actually, but they are supposed to be like 33.08 or something, so yeah the rpms will be higher, especially as the tire starts to get towards the end of it's life. I do plan on going to 35's or 36's one day, but these 33's are still pretty new so I will ride them out.

Oh and I do plan on going ARB up front if I do regear. As has been said before, it is almost stupid not to do it since you are already in the front end.

 

i think you'll be happy with 4.56

 

Fawk that if I'm going to do it, I'm going all the way I don't drive this thing for the fuel economy I have a car for that

 

Then do it. you'll want gears before a crawl box any way

 

Did you not learn anything from Honey Badger?!!! haha. I don't know how many times I heard Jared say crawlbox before gears, although I think that depends on your goal. In a buggy/crawler I agree with him. I felt like my tacoma performed just fine in Moab with the 3.73's. It's on the freeway, where I want the gears. I'm not lacking for power or anything, but with the 33's the transmission favors 4th gear over 5th, so it will be nice to have some torque restored at freeway speeds.

Also username, I was just looking and you have the 6 speed manual, while I have the auto. On paper with tires that are exactly 33" and 4.88 gears, your rpm's at 75mph would be 3165, while mine would be 2669. Your 6th gear ratio is .849 while my 5th gear ratio is .716.

 

I have a 5 speed manual.

too many choices and I'm not following this thread as closely as i had been. forgive my ignorance.

 

I was think about a crawl box too. But you have to get new drive shafts and other stuff. Would be the same cost wise as a front locker gears and oba or co2

 

Yeah, I'm sitting at about $2000 for the gears, locker and OBA, while the taco box is $2000 itself, but the tacobox would be amazing for crawling.

Mike and JW discussed this a little in Moab, but were unsure about some of it. I researched it out when I got back and was kind of surprised. So to figure out your "total drive ratio" or whatever you want to call it, you take your first gear ratio*tacobox ratio*transfer case ratio*diff gear ratio.

For me without the tacobox, that is 3.52*2.566*3.73=33.69. As you guys probably know, that means that you engine has to rotate 33.7 times to rotate your tires once.

Add in the tacobox with the 4.7 gear ratio and you get 33.69*4.7=158.34 That is a huge difference. Getting 4.88's instead of the tacobox would only get me to 44.08.

Just to put this into perspective, my engine red lines at 5500rpm. On 33's with the 33.69 ratio, I would red line at 16 mph. Regearing to 4.88's I would redline at 12.3 mph. With the tacobox I would redline at 3.4 mph. With both the tacobox and 4.88's it would be 2.6 mph.

Sorry to pull a Ben but that is a huge difference and I kind of think this math stuff is cool

It really just depends on what your needs and wants are. I like the Moab crawling, so a tacobox would benefit me greatly, but due to possible current circumstances I may be getting gears first.

In your case Monte, the choice is lockers vs tacobox which is pretty easy, because the tacobox wouldn't help any (in fact it might make things worse) without at least a rear locker. I already have a rear locker so the choice is front locker vs tacobox which is a little harder, cuz the front locker isn't as useful as a rear locker.

 

Actually a taco box would help a lot. I made it up everything I tried fine. My biggest issue is I can't stop on a hill due to the large tires and power loss with my 4.10 gears.

But if I got the crawl box id gain my low end and beadle to go up obstacles much better.

I was also considering not regearing if I got a taco box cause then the taller gears do better on the hwy.

Either way for me..none if that ishappening this summer lol

 

Haha. Guess it depends on the obstacle and terrain haha. Take the obstacle in my sig pic. Without lockers you either had to get some good momentum or pick a good line. With my locker, I made my own line on it.

When I said a crawl box wouldn't help you much without a locker, I was picturing obstacles where a tire would come off the ground or in loose rock where traction loss was highly likely.

 

Its all about the line

And even in that situation it would help a lot due to such a low ratio

 

Could you imagine something with triple transfer cases? haha. Granted I don't think there is much a 1000:1 ratio can do that a 100:1 ratio couldn't also do. haha

 

Let's build a custom rock buggy with three lol

 

Haha. We'll use a transmission with a 4:1 first gear, followed by 3 transfer cases with 4.7 gears and finish it off with 5.29 diff gears That's a total of almost 2200:1! haha. That would make my engine with 33's redline at 0.25mph! 50" tires would redline at 0.37mph

 

Looks like you are taller haha. How was the first day of work on your own?
