Club 80-90 Forums

you could get 65 @ 3100 ish with 6.16`s but you`d have to run 245 /75/16`s and i`m not sure you`d manage that with the 16" arches.

with my tyres you`d be about 3300 @ 65mph

what tyre size you running?

i'm running 205/80/16 on standard steels
just checked that size (245/70/16) it has a 40mm bigger diameter or 5.45% bigger. What width rims have you got them on?

i`m running 255 / 65 / 16 on ml`s. think their 7"

you should get 65 at about 3300 with those tyres and a .7 4th. still a bit short really.

you must be doing nearly 4000 @ 65 now.

I think 60mph is 4300 and 50mph is 3900
Just looked it up 60mph =4130rpm
50mph = 3400rpm

So is a .7 4th the longest you can get then?

Would love a diesel rev counter to fit in place of my clock

yes i think .7 is longest 4th. aidan would know for sure.

lloyd are you sure those figures are right. seems very low geared even for 6.16`s

got it from here http://www.rjes.com/html/gearbox_types.html" onclick="window.open(this.href);return false; my code is AVU (6.17)

looking at that again, its rubbish! based on 14" wheels
this one is better http://westfield-world.com/gtc.html" onclick="window.open(this.href);return false;
with my ratios and gears
49.2mph = 3000rpm
57.4mph = 3500rpm
65.6mph = 4000rpm
So not as bad as i first thought
Whats a good rpm for constant driving on a AAZ?

thought those figures were wrong. the rjes figures are for much smaller tyres. my figures will be closer to correct with the size tyres you have.

Panic over then 60 on a TD gearing is 3200ish, saying that I kind of headed off when we did the foot down test

I never chased you though
It just sounds as though i'm thrashing it by going over 60. Really need a rev counter

And the two stage fan kicking in? maybe it was slightly highish.... Chuffed it isnt as bad as it could be though

Fan wise, it does run a bit hot, if I do a constant 60 it will sit to the right of red light, but water temp is about 90 and oil temp slightly higher so not to bad. But hit a hill and temp climbs quickly (it falls quickly as soon as hill finishes) I have a feeling that the rad is not as effecient as it could be, looks to be original one. So might get a new one. But all this could be normal?
Gears are better than I thought, but the van feels a lot happier at 55 than it does at 60

AAZ's do get hot on long gradual long straight climbs on motor ways, but like you said soon cool down again.
