gearing my zook

finally got the pile of crap back in action thanks to Mud4b with a 1.3 efi conversion :D

Downside is that now I found out how overgeared it is :shock: Its running 3.9 centers (wt diffs), S3 rockhoppers and "31" inch x terrains. I don't have a tacho but it's flat out like a biscuit at 100k's :roll:

The prob is worse because the xterrains measure 30" on a good day :x 29.5 on a bad one :?

Any ideas how to get it liveable :?: I was thinking an upgrade to a genuine 31 along with a swap to 3.7 wt centers (already got a front). But how much difference do you reckon this'll make... like can I then do 110 @ around 4000? can't go bigger than a 31 around here either.... 31's get enough negative attention :roll:

I think if you do both the real 31's and centres that will make a difference. Doing only the centres i don't think will make much of a differnce.

we need the gear gurus here.

cheers

there is a one piece double gear bit involved, so I doubt it, without major work?

mmmmmmmmmmmmm no :D Anymore advice :?:

By my calculations its pulling about 4700 at 110km now :?

3.7's and 31's should knock it back to about 4100 :? 1.3 efi should be happy there I'd imagine.

What muddies etc (road goer) measure a genuine 31 :?: would like to keep the width down too. Will even go a 32 if need be :roll:

go the mongrels
i run 32x10.5x15s on my daily driver and they are great
measure about 31.5 on 8" rim.
with 1.6 efi, s1 gears and 4.1 diffs impulling about 3600 at 110 in 5th

I'll have to wait for your opinions on them as a daily thing then :cool: I would imagine they'd sound like a light aircraft and handle like roller skates in the wet :lol:

i wont be finnished my zook till near the end of the year and i have just sprayed a good thick coating of blackjack/sound deadner all over the floor in preparation for any unwanted noise (and just to be sure i'm going to give it another good thick coating when this one dries out more) but my zook will not be my daily driver thats what my hilux surf is for!

(sorry for the hijack)

I could also go 16" inch rims giving me choices of taller and narrower tyres :idea:

eg I could easily get a 265/ 75 then which is a 31.9" tall 10.5 " wide tyre. That'd fix my gearing by itself :idea: Cheaper than buying a wt center too by the time I sell off my x terrains + sunraysias :idea:

I seached and found new 16" sunraysias would be the go there

could be a simple solution

I run Mongrels as a daily driver....handling in dry is great, and in the wet is much better than I expected. Being built on a radials they have many road holding advantages.

Can't comment on noise due to poor hearing, but I can feel a slight rumble when going slow, and at speed rest of zook rattles and makes more noise than tyres ever could :)

Time will tell how long they last, but so far so good. Have done most of summer, lots of trips to the hills on tarmac, and quite a few extreme 4wd trips..I'm happy, but would recommend new tyres if you can afford them.

I used to run 3.7 centres with s3 and 31's for the road and the gearing was fine at 100-110 km/h was around 3600 3700rpm at 110km/h

There are some good choices for 16" rims I run 255/85 r16's on modified GV rims which are about 33.4x9.5" wide, you could try a 235/85 r16 its 32x9" wide, I have a friend running this in MTR's

235/85 sounds great stephen :) When you say modified gv rims is that just for offset :?: or the center hole :?:

I still reckon speedy wheels will be the go......... but you never know
