here were the results:
30.1mpg....60mph....2180rpm....17 miles....193watertemp.....700ft
35.1mpg....50mph...1825rpm...15 miles......190warertemp.....650ft
I'll run the same stretches going home on friday and post up.
Also got my first tank to tank fill. (well 1/2 a tank) went back and forth to work about 29 miles 90% freeway. stop and go about 1/3 of trip. And one trip at 70-75mph
The kia trip computer said 25.0mpg, the actually fill up was 23.65 over 198 miles
Need to run a couple of 350-400 mill tanks to get a better feel.
But gas in San Antonio was 3.09 -usually 3.18 - (less 12 cents HEB grocery store card) and I didint want to pass that up!! 
I think that the data tells me 2 things.
1. need a lower and probably up grille block to warm up faster. ran the 50 mph AFTER the 60 mph and the water temp dropped (190 was the high. it was 186-188 at times) The 193 for the 60 is also pretty low.
2. The 70 series tires seem a logical next step. Lower rpms will help. maybe I can get down to 1975rpm at 60 mph! |
30.1mpg....60mph....2180rpm....17 miles....193watertemp.....700ft
35.1mpg....50mph...1825rpm...15 miles......190warertemp.....650ft
XXXXX.....60mph....2045rpm..........
XXXXX.....50mph.... 1736rpm.........
Dropped about 100rpms with the larger tires.
Remember they are used and I like the ride alot better with the larger tire.
Havent had a chance to test mpg
