96 4.6 HSE with 265-75R16's BFG All Terains, OEM gearing with Superlift true speed speedo/odo correction module. Conical K&N in OEM air box, Power Chip and Borla CAT back system, 98K miles. 11.0 to 11.6 MPG over the weekly comute of 32 miles round trip. It is a mixture of highway and surface streets. Usually the trip computer says my avetage speed is around 30MPH � 5MPH. Best was 17.0 MPG ,cruise control set to 70 MPH, on the way to MOAB, 750 miles one way. Top speed around 110 MPH. | ||

Average MPG should be 13.5 to 15.5 depending upon how you drive. All 1997 Range Rover have engine immobilizer | ||

I used to get 13-16, but I just took out the EAS and put on some Dobinson shocks with 32in muds now I get 9-10 in the city and 14 on the highway. Andrew, where did you get the speedo/odo correction module? Have you noticed much difference with your K&N air box? | ||

Superlift makes the TruSpeed Speed Signal Calibrator. I seem to remember someone having an article on the web about fitting that to the RR but don't recall where at the moment. http://www.superlift.com/speedcal.asp | ||

With my 95 4.6 P38A (currently at 156,000km - 97,000 miles), around town I get 18 litres/100 km on petrol and 22 litres/100km on LPG. On a trip at freeway speeds, 13 litres/100km on petrol and 18 litres/100km on LPG (you blokes can convert to US or Imperial MPG - the rest of the world will understand litres/100km) Ron | ||

Robert, Pugsly is correct on the Odo recalibration module. Just contact superlift and they can get you set up with the right unit, roughly $100-$150 I think. You have to splice it in between the ABS processor and the BeCM so putting it under the passenger seat on top of the BeCM is a good place to mount it. I wrote down all the connections and stuff you neet to make I'll try to dig it up. The conical K&N filter is better. I was getting really frustrated with the OEM K&N replacement filter as it fit very poorly in the air box. The only way I could seal it was to "right stuff" bond it to the lid. This made cleaning it a bugger so I pitched it after a years time. The conical filter has as much surface area as the OEM filter. My thinking is that the pressure drop across the conical shape makes for a better feeding of the air into the MAS sensor and intake tract to the plenum. Hopefully its more laminar and less turbulent than what the air box did in trying to send the filtered air across a large rectangualar cross section. The good thing is it is still sucking air from outside the hot engine compartment. I ran the EAS air filter into the air box as well so its sucking cooler air too. E-mail me if interested and I'll shoot some digital pics of it for you to take a look at. Ron, your 18liters/100Km on petrol makes my head hert in trying to convert it to units I live with. But thanks for the SI take. AP | ||

Hi Andrew, I thought of giving the figures in MPG - but I'd use Imperial gallons so you'd still have to convert it 8-) Ron | ||
