Feul economy, whats that?
1977 f100 2WD. 351 Clevo,C4, 4.3 gears. On the open, straight road cruising at 80kph, it gets about 16L/100K's. Around the suburbs/city (always results in a little playing) turns to K's/100L!!!
It's good that the servo's are close by, not so good Premium is so expensive.
F100racing, I reckon you'd soon fund the addition of a bolt on overdrive unit on your 3 speed with the fuel savings!
Then again, 16L/100k is pretty much what my 4.7 V8 Landcruiser used to get, albeit at 100kmh. So the OD unit would probably just make you 20kph faster for the same 'economy'.
I have thought about an OD unit but don't really need it.
It only hits the open road once or twice a year. Around the
city i have no need for the motorways.
At the moment i'm saving my a$$ off for a carb,manifold
and new stall. Not sure if thats going to help or make it
a lot worse.
Last truck 1988 f250 7.3 idi , auto with gear vendor overdrive, 4x4 got 12 liters per 100kms. That's pretty good mixed highway/town, probly a little more highway tho. (Also most efficient out of the 9 f trucks I've owned)
Truck before that was 1991 f350 efi 5.8, 5 speed, 4.11s with 35s, used to get 25-27/100. Was horrible.
Didn't really check any of the other trucks, had a carby 460 one that had gas and had to disconnect the gas for a week to check tanks, and that was by far worst economy I ever got.
I just did a test, did 656 km for 103 litres, mixed driving mostly highway, and about 50km towing my 20ft caravan! That's with superchip on performance and 6637 and straight 3inch pipe. I haven't worked out litres per hundred yet so can someone? Next full will be real test, towed the caravan 100+ Km, most pretty hard fast.
