hey guys, just out or curiosity what sorta economy are people getting with there Jimnys

running 235s, 30s, ect

[Jezza86]

30*9.5 km2's with a 27% gear reduction to get 4150rpm@ 100kph, tyre presure 32psi, geting 370k from 40l with a m13A vvt
10.8l/100
9.25km/l
usage practically doubles in soft sand

[zammit]

jesus thats vterrific i though it would be a dramatic down fall in economy.

[jimny_timmy]

Fully loaded I was doin 14.5l sitting on 110

[zammit]

you guys find the 1.3 still pushes it along no worries with the bigger tyre, obviously with reduction gearing.

[jimny_timmy]

Yeah it does the job just fine... Although everyone loves more power deep down inside

[zammit]

ah righto, i only wanna run 235s anyway

speak for yourself lol
i must be a gutter minded individual

the m13 is overworked and is slightly labored in a slight headwind in 5th with 30's
so if your nit immediately down changing to 4th (or just driving in 4th all the time to begin with) you can expect 14l/100, especially if your ruining tire pressures lower so your spine doesn't shatter.
i would not want to do many k's (especially on the roads here) with 32 pound in the tyres.

I mean more power in the shape of an m15 or 18 mate

I was getting 300km to a tank - 320 at best with 30" KM's Auto VVT Transfer and my 1.3

I haven't finished a full tank on my 1.8 yet - back tot he stock transfer and 30" KM2's

[Jezza86]

JK what pressure were you running? i was geting about that with 26PSI

[JayKay]

28-30 psi difference is I carry a lot of crap at any time - tools ETC

[Jezza86]

i was also wondering what runing a jimny throttle body does in terms of economy on a M15.
the WOT power figures would have to be lower with the jimny throttle body has more restriction *then the m15 body8, but when the butterfly is the point of restriction (and assuming the air:fuel ratio is maintained) the only extra energy loss is a marginal increase in friction from the additional piston circumference so fuel economy should be fine unless your at WOT. in effect it would be harder to labour the engine.
*edit*

[Docka83]

235's auto vvt m18 get about 300kms running 98. A bit more if I up the tire pressure but you feel it on road.

[Dorfl]

Around 265 klm per tank (~34L) 2008 M13A VVT 33" x 12.5" tyres running 25psi front & 29psi rear
