So i thought itd be interesting to see what kind of gas mileage people are getting with the mods they have done.
Ill be first to state my mods and mileage.
4.0 SOHC
4.10 gears auto tranny
Wix Air filter and silencer removed
NGK V-Power spark plugs
Freshly rebuilt rear axle from Ford
New front wheel bearings from Ford
33x12.5r15 Pro Comp Xtreme M/T tires
15x8 Pro Comp Xtreme Alloy aluminum wheels
3" body lift
2" Torsion twist
216 miles on the odometer when i filled up
filled up with 19.4 gallons
compensating the difference from the stock tire:
heres a way to calculate wheel circumference:
29" stock tires
29/2=14.5
14.5x3.14=45.53
33" mud tires
33/2=16.5
16.5x3.14=51.81
51.81/45.53= 1.137
equals 13% difference in registered mileage
216x1.13=244
244miles/19.4 gallons=12.5 mpg
i would really like to improve on this, i drive as slow as possible as it is.
im going to change to a smaller tire (31 or 32)
and do a catback exhaust
a XCAL2 would be awesome but i dont think that will happen anytime soon
