Outer Limits 4x4 Board

Just wondering how others fuel economy is with this conversion??

I have dual fuel set up on mine at the moment and seriously thinkin of taking the gas system out so it can be tuned properly.
Thanks, Tim.

hey im running the manual with 4" lift and 35s with no speedo sendor and im getting 25 - 26L per 100km

Im getting aound 18-19L per 100km, with auto, 2inch body, 2inch suspension and 33's. (swb)
Hoping to get it down around 15L per 100km.

well i havnt got the 5l in my GU yet but im hoping to get around the 14-15 on highway and high teens round town taking it easy!(on gas)
thats with 33's,4.1 diffs and 2.5 inch lift!

iv got a custom made loom and speed sensor,hsv chip,snorkle and hsv headers!
had the head port and polished,shaved and set up properly for gas!
all new rings ,bearings, belts,chains,leads plugs etc


now only bout 3 weeks away

Hi ,I've got the 5lt in my GQ dual cab with 2" lift on 33's, getting around town about 19-20lt /100k's and on the Highway about 16-17lt/100k's,just got to try and keep the foot of the loud pedal a bit more nope to hard

Im not expecting too much from it then.
Keeping of the loud pedel might be a bit harder now, has some cracks ruond the muffler so im just goin to get 3"cat back

Highway usage quoted there, is that at 100km,110km,120km? Smurf.

Simcoe, are you using gas injection setup? Didn't think it was possible to get that good economy from gas?

no not running gas injection Mongrel, im just "hoping" with all the head work done and custom speed sensor and new gas computer/mixer etc and keeping off the load pedal that it shouldnt be that thirsty!
or to put it bluntly, im hoping it's alot better then my 4.5..

iv also had some advise on exhausts and iv been told to get 3 inch for first half of the system then 2.5 from then on!
ie 3 inch from collector to 3 inch cat then 3 inch to muffler and 2.5 from the muffler out the bum!

iv already got a 2.5 inch system so i just need a 3 inch cat and piping for the front!

also Mongrel, what gearing and tyre's are you running?

Average of about 100-110 km's, sits on about 2100- 2200 rpm in 5th sitting on the 33's ,with a couple of sh#ty injectors that need to be replaced

Funny, that exhaust system you suggested... Is what mine has now, mines drops back to 2.5inch after the cat before the muffler, with the dual fuel.
Not sure on the diffs, 33inch tyre's at the moment.

the gearing will be my biggest "look into" im thinking..
currently sit at 2300@100km/h(GPS) 33's with 4.1 diffs!
110 see's about 2500..
sounds abit to much for my opinion for a v8 to be reving!
time will tell!
looking into 3.9's

also anyone got any hsv 304 headers lying around??
i need some!!


woot
