looking to change my axle ratio

So the companies that you listed before that are running this setup you are so fond of, the ones that I spoke of in the post you quoted, they are now somehow not valid?

 

Allan said the drive shaft slows down in direct. So, no way it should run hotter.

If you run a 3.55 in direct and you hit a faster engine rpm, your in the wrong gear and should upshift to OD. The engine rpm would go up to maintain your top speed, but you have 1 or 2 more gears that you should use if you have a 3,55. it would be stupid to run a 3.55 in direct unless your downshifting for a a hill. If you rpms creap up, then you should be in a higher gear.

 

Not more power to turn 2.64, mor power to climb a hill

 

If bruce says it, you can take that to the bank...He is a motor and gearing genius.

 

You do relize that if motor rpm drops, heat drops. this isnt an affect of being in driect or not, it simply you slowed the motor down by 200 rpm when you shifted. gte it back to the same stress and rpm in the od and it will heat up more.

 

ok ok I agree. Maybe a few more gears?

Lets compare the setups:

Low gear is 39.263 on the 10 speed OD setup
Low gear is 39.4416 on setup "B"
Low gear is 39.4152 on setup "C"

High gear is 2.6625 on 10 speed OD setup
High gear is 2.64 on setup "B"
High gear is 2.64 on setup "C"

Next gear down is 3.55 on 10 speed OD setup
Next gear down is 3.3528 on setup "B"
Next gear down is not known on setup "C" but would be very close to "B"

Startability would still be acceptable, but we have narrower gears like a 13 speed.

Would that be acceptable?

edit: I forgot to add the ":1" these are ratios after all.

 

Excuse the correct spelling etc, but I fixed that for you.
You're welcome.

Like a 21 speed bike, you have 2 ratios you can control. You could climb that hill with the biggest sprocket on the peddles but the smallest on the back. The fron in this case is your rear end. You can choose a gear set and stick with it. the sprocket on the wheel is our transmission (backwards from a truck) You still have 7 gears. Choosing the smaller sprocket on the peddles will give you a lower 1st gear, but once your moving, you have enough play in the wheel's gears that it really doesnt matter.

 

yea, but, the trans makes up for that. if you were turning the trans imput by hand it wouldn't matter as long as i got the truck moving.
