Freeway flyer with 1776?

[Next_Racer]

I know nothing about transmissions, sorry to say. I would like to replace our transmission on our Splitscreen bus (1963). The bus has a 1776 engine with 60hp and 110Nm torque. The new transmission will run with reduction boxes again. I was thinking about a freeway flyer with 3.44 R&P and a 0.89 4th.
Would that be possible? Tires size 215-75 R15

edit:
Using the stock 1.39:1 reduction boxes

Thanks

I think u need lots more engine or do the reduction boxes and no less than a 3.88. Even then it'll be tough.

Your stock gearing would have been:

.82 fourth x 4.125 R&P x 1.39 RB = 4.70

Your proposed gearing would be:

.89 fourth x 3.44 R&P x 1.39 RB = 4.26

Probably doable, IMO, particularly because you are keeping your original 1.39 RBs and running a mild 1776.

If you plan on keeping your 1.39 RB, an intermediate option would be:

.82 fourth x 3.875 R&P x 1.39 RB = 4.416.

Bolt in and go, but talk to your tranny builder first to determine the correct R&P based on your tire diameter and engine output and driving needs!

^^^^^ What Bruce said.

3.44 would be an absolute mistake. With an engine less then 100 HP, and taller then stock tires. I would stick with a stock geared transaxle

Ok the 3.44 is not a option!
But would this be an option?

1st Gear: 3,78
2nd Gear: 2,06
3rd Gear: 1,26
4th Gear: 0,82
r&p: 3.88

yes, that sounds like a good choice with 1.39 reduction boxes

Hey, key board jockeys!https://weddleindustries.com/gear-calculator

plug in some numbers and figure it out! Don't forger that the ring and pinion number is multiplied by the reduction boxes.

Also, there is NO SUCH THING AS A FREEWAY FLIER! A custom geared transaxle maybe

Have you played with the numbers with this?
http://www.thesamba.com/vw/archives/info/rgb_calc.php

Can we assume you are still running the origional small nut transmission?
The simple option would be to just get the R&P changed Bears or Cogbox if you are UK based

A quick play with your Tyre size ok 4000rpm may be to high for extended runs but you get the idea.

RPM Tire Diameter Gear Ratio R&P RGB SPEED AT RPM
4000 27.7. 0.82. 4.375 1.39 66
4000 27.7 0.82. 4.125 1.39 70
4000 27.7 0.82. 3.875 1.39. 75
4000 27.7 0.82 3.44 1.39 84

Ok does not answer will the engine actually push the bus with ratio x

Thanks for the info guys.

I've bought this gearbox:

1st Gear: 3,78
2nd Gear: 2,06
3rd Gear: 1,26
4th Gear: 0,82
R&P 3.88

I'll let you know within a few weeks how it runs.

Well you bought what is commonly referred to as a freeway flyer. It's going to suck. Whoever was your trans builder should have asked what your stats were and then talked u out of it. You'll be downshifting lots to 3rd. Have fun.

You guys can't do math at all?

With the reduction boxes it's geared almost the same as a 1970 bay bus.
I don't see a problem, it should work
5.375x.82=4.41
3.88x1.39x.82=4.42
