Mine is second gear with a 22re front case in high(2.28) and rear case in low (4.70) and 5.29 in the axles on 37s and don't have a tach so don't know rpm there's a chart some where but I'm to lazy to look for it :****:

I'd don't have anything cool, or with power. But from what I have seen, topping out in the mid to low 50s in 3rd(drive) seems to work very well for most hill killers.

With the iroks at 6000 rpm (im assuming your case is 2.0): 1st- 34.6 mph, 2nd - 57.4 mph, 3rd- 87.3 mph.
This seems way too high to me, do you stay in low rpms alot using the high stall? If your not reving motor high enough it will seem alot lower than it actually is with high stall. This would slow you down alot. or have lomax gears?

Not very familiar with toyota stuff. is that two transfer case gears (to be doubled?) What the ratio in 2nd gear in tranny?

With the stall it flashes to 3200 maybe alittle more. If that's figured in low range those speeds seem way off to me there's no way it will run almost 35 in first low range. Something there don't seem right ???

i know its weird, it has to be the stall converter. id be willing to bet if you went lower on stall you would feel more sluggish.

I guess it does but I climb most things in second. I can be on dry blacktop in 2 high and friggin blister those 42's. I no the numbers don't lie. Maybe the motor has a little more power than I think. I no it's not under powered by any means. I just can't see it running 35 in low range 1st gear hell it would be cranking 10 grand. I've got the rev limiter set at 7 and don't think I've hit it yet.. With the stahl it's hard to crawl things because it's up in the rpm and blows the tires off. I've been debating on smaller stahl or gears. What would you guys suggest ? I know the things I should be easing over and small climbs I could go up at a slow speed I'm coming out spinning at around 4 grand or better. I in no way have a bouncer or anything close to one . It's just a good trail jeep . Moderate hill climber. I guess when it feels high geared is on long easy trail rides, the things you should be cruising about 2 grand. With the converter unless it's down hill that's not happening.

If you are going to have 500+ hp i would go with 3.0 & 4.56 or 3.8 & 3.73. We went from 4.56 to 4.10 in ANGER MANAGEMENT(Nick Cooper) with a 3.8 because he was running out of gear.it seemed to help a little but, now he wishes we would of used 3.73. I would try to keep your final ratio somewhere in 13 to 15:1 area.

well, if you decrease stall you are gonna be putting alot more load on engine at lower rpms and it may seem alot weaker. There are several ways you can do it, the easiest might be doubler on case, or lomax gears. Runnin gear would have to be in the mid 5's to 6's to get it down, but then your gears are weaker than they are now. the lomax case would be a huge change and would be stronger than what you have, you wouldnt be hurting yourself anywhere and i doubt you wanna do gears and case both, thats just even more money. if it were me id look at doubler or lomax and decide what speed i wanted to have and choose whichever one gave me that.
doubler 4.0 case - 17 mph 1st
29 mph 2nd
44 mph 3rd
lomax case - 23 mph 1st
38 mph 2nd
58 mph 3rd
doubler 4.0 case - 17 mph 1st
29 mph 2nd
44 mph 3rd
lomax case - 23 mph 1st
38 mph 2nd
58 mph 3rd

My 2cents which isnt much!
Rig, the retro rockrod
Wore out 305 180/200hp at max.
700r4 208, d300
43 tires 4.56s
With the 300, in low 2.62 i think. It was fine crawling. Very seldom i ever used the doubler.
When i was trying to shoot hills i would start un first and shift to second, second had plenty od wheel speed, but my motor was not enough to pull it on anything very steep or long. If i would have had more motor, i think that combo would have worked really well!!
My next build i plan to run a 3.0 of some sort, and 4.56s not sure on tires just yet.

That looks pretty good. Would you change anything if you could? im having trouble now deciding 3.0 or 3.8. Would really like the lomax 205 i think. 3.8 would have to be atlas.

Rpm's multiplied by 60 multiplied by tire circumference ( actual diameter x 3.14) divided by 5280 divided by crawl ratio.
(6000 rpm) x( 60 min) x (11ft) / (5280 ft) / (crawl ratio)
your crawl ratio looks off.
first set up:
1st: (2.52x2.43x6.72) = 41.2.......20.6mph
2nd: (1.52x2.43x6.72) = 24.8.....34.3mph
3rd: (1x2.43x6.72) = 16.3.........52.1mph
2nd set up:
1st: 38.3..........22.8mph
2nd: 23.1........37.9mph
3rd: 15.2.........57.6mph
I understand that figuring mph like this is not exactly right because you lose a marginal amount of power from motor to wheels, but ive checked the software that accounts for this and my numbers arent but 1 or 2 mph off at most.

That was the second time I had the buggy out and so far I love it.Last rig before this one I had a doubler with 4 to 1 low and 5.13 gears and it was too slow at times . Didn't have the wheel speed sometimes . Had stock engine also. The new one I think has the best of both worlds , has some wheel speed and can still crawl.Roy_Hobbs said:
