 High altitude - what about boosting input pressure?
I have a 1993 Corolla (1.77 liter 7A-FE engine, 4-speed o/d automatic). For
business purposes I record all gas purchases (call me reluctant...). Annual
average consumption (miles per gallon) data are:
2000 36.8
2001 38.2
2002 36.5
2003 29.4
2004 34.4
2005 38.9
2006 36.8
2007 34.3 so far.
This 3500-pound automatic fuel-injected car often gets 45 or even 50 mpg on
the highway. The averages above include mixed highway/city driving, utility
trailer hauling, and (16' canoe) roof loads. I notice that the vehicle does
not underperform at high altitudes as older, carb-and-distributor cars
would.
Good luck to you up in the high country. - Jack. |
