Last week I drove from San Francisco To Sacramento and Back....
(224.86 Miles total) "from where I live" and I averaged 20.5 miles per gallon.
Its a 1999 Merc Mounty AWD 5.0 with 70k miles on her.. and a 22 yr old Driver....
I was very suprised tho , I was mashin the throttle a bit and going up hill in my AWD 5.0 Mounty....
I fueled up with 91 octane Before I left, I also shortened The throttle cable, Added some octane booster, I also have dual 40 series flowmaster with cutoffs, I also changed the engines oil to full synthetic after I added "engine restore". then I changed the TC fluid with some Synthetic ATF. I also Sprayed the Mass Air Flow Sensor with some carb cleaner before I left. I just ordered the Tornado insert, 1.7 Rat. Roller rockers, ford racing valve covers, 1" intake spacer. Some Ford Coil Pack, 4-Tower, PN 8241 thanks to JTsmith,
Also I will be ordering some TM Headers, Iam starting to think twice about the DSS 331 Stroker....
Gas Prices around here are killin me at 3.40 a gallon, So basically I want it as fast as it as fuel economical. any other Ideas.. Im thinking of converting the AWD to a 5 Spd manual....
I also will be having jah81592 from hensonperformance burning be a sct chip with a fuel econ setting..... I was also thinkin about a adjustable fuel pressure regulator..
I think Iam on the right path
