Outer Limits 4x4 Board

What eco should I be getting from my 1hdt 80 SERIES. Its completely stock apart from 3" mandrel exhaust.

Can I get some standard tyre size figures?
And some from dbigger tyre sizes (33, 35 muds)?
Also what rpm at 100kph?

Cheers

I get about 12l/100km I have had it down to 10.5-11 but yeah that was driving very carefully.

Now with a roof rack on, I am getting 13-14L/100km

Mine has 32inch tyres a bit of weight and Exhaust same as you.

Why don't you also post up your figures?

Because my figures are all over the place and I dont have anything to compair with. I bought it with 35 muds (puts the speedo and figures out)and stock 4.1 diff gears. Also have been driving it a bit hard. Ive also been using moreys diesel aditive to clean out the system a bit (higher octane) so that changes things aswell. Ive just put 4.5 diff gears in it.

4.1's - 35 muds = 2350rpm at 100k's per hour (90 on the speedo)
4.5's - 35 muds = 2450rpm at 100k's per hour (100 on the speedo)
It doesnt sound right, but that what it is.

Im trying to gauge how much difference it has made to my eco, but nothing to compair it with.

Roof racks make that much difference?

A roof rack as well as my right foot. The note of the new exhaust is great.

Just post up what you were/are getting, someone will come along with the same mods as you and say they are either getting the same or different.

last tank i got 13.6l/100kms which was driving camping/4wd/hwy/daily with a heavy right boot.

usually get high 12's when driving conservatively.

with 33 mt's and 3" exhaust. figures adjusted (speedo is 5% out)
