yea the diff makes alot of diffrance. i now get 80km @ 2000 rpm not 3000rpm & get 100km @ 2600 rpm with the 202 standard Bedford 4speed & cresta diff (3.45:1)

i'm happy for now.. but the clutch is very heavy so may have to look at somthing there..

Gday,
Ive inherited my late fathers 76 CF Motorhome, its a long wheelbase dual rears with 202 motor and 4 speed manual
He had a ford 9" diff conversion and changed the ratio to 4.1:1 but she runs out of puff on the highway at 90KM/h

its running 14 inch tyres and has extractors for more power.

Would changing the ratio to 3.5:1 or lower get me similar results to your camper?

My camper is fiberglass 10 feet wide 21 ft long and nearly 9 foot high so she pushes a fair bit of wind and weighs about 3.5 tonnes

any ideas on how to make her keep up with the traffic on the motorway?

thanks

Ian from Brisbane.

change it to a 3:23

You might have trouble if you change the diff ratio with the 202 hauling that kind of weight especially with the wind resistance getting up to 100k. You might cruise at a better speed but it'll take you a long time getting there and your trans won't like you one bit either. I rather think that if you want any better performance out of it you are going to need to consider an engine transplant along with a new diff ratio.

Ian, stay with the 4.1 ratio, or even look at putting it back to the bedord lowest ratio at 5.1 and put in a 5 Speed, good low down power and 5 gear for the open road. The cheapest way by far. I run a fully worked 202 and 3 speed Trimatic with overdrive and low diff ratio in my Camper that sits on 2-3 tone. Magic is  all I can Say, but ofcourse Rouge is right, if you don't mind spending the money a transplant is the go, or the above if you don't want to spend that much but get a little more power.  Cheers, good luck.

Sorry for taking so long to respond, I've been on the road as part of my work and this is the first opportunity to reply.

Im not wanting to change the motor, cause its only done 12k since a total rebuild my Dad did on her and she runs really sweet.

Reading over some correspondence he had a bit of a fallout with the crowd that did the diff conversion and they talked him into the 9" 4:1:1 and he traded in the origonal 3.5:1 diff but he was upset that he was not getting the 100KMPH +  hiway speed ( Having driven her from Cairns to Brisbane, I know the fustration of having all the traffic backed up behind you cause you cant keep up with the speed limit and keep having to pull over cause you cant get the old girl past 80 kmh on the 110 freeway.)

If I leave the diff and the motor as they are but looked at swapping the gearbox for a supra 5 speed like the W59 with over drive around .8 and first gear 3.59:1 will that still be quick off the mark at the lights and pulling up hills, but give me the top speed on the hiway with out reving the guts out of her?
Im not very good at working out the ratios so any laymans help in understanding what I need would be appreciated.

Alternatively, if I put in a trimatic, auto box, which you seem so happy with for your van (and would mean my wife could share in the driving as she cant handle a a manual  ) What set up would be required? Are all trimatics the same or would I need some specific model for my big heavy rig?
Im in Brisbane so where would I go looking for an auto box or the supra

Thanks in advance for your interest.

The Trimatic is only 3 speed so you will still have the problem with top end. There is a Trimatic with a overdrive fitted so this would give you the top speed you require, but you would be very luck to find one, not sure even if you can get then in OZ. I have one in my van in NZ. So your best bet is to go for the 5 speed they are lower geared than the 3 and 4 speed boxs  in the first 4 gears and the 5 gear will give you the top end you are looking for. The only problem you are going to have is the clutch set up it needs to be light on the foot for a smooth drive, some of the guys on Buga have over come this problem I think, so have a talk to them. Cheers
