No_6 Posted September 11, 2006 Share Posted September 11, 2006 I'm just curious as to what other people are getting out of their car. So far, my car is getting around 22 MPG on the freeway. When I put the spurs to her, it drops to about 15. Ouch. This is with a 1700cc x-flow with 149.5 peak horsepower on tap (and no, the motor isn't particularly fond of lugging around under 4k, though it does so dutifully).

slngsht Posted September 11, 2006 Share Posted September 11, 2006 That's pretty low I think. I've only measured mine once... mixed twisty road driving, and cruising at about 75-80 MPH. My car is almost 1700 lbs without me, and has a 5.7L V8. I got 26 MPG Link to comment Share on other sites More sharing options...
Mike Rohaley Posted September 11, 2006 Share Posted September 11, 2006 I usually average 28mpg with about 25% of the time being highway miles and squirting off the line whenever possible on the streets. 100% highway mileage is around 32mpg (at 70mph...ish). The car is a 2001 fuel injected Zetec, completely stock mechanicals save for the lightweight flywheel. On the track it probably drops to around 10mpg, however, I never bothered to check exactly.

JohnCh Posted September 11, 2006 Share Posted September 11, 2006 Welcome to the wonderful world of crossflows and webers! Your mileage is only 1-2mpg worse than what I used to get with my old 120hp crossflow. My Duratec on the other hand has 190hp and typically returns 25-28mpg in city/back road driving. Of course it doesn't sound anywhere as near as good... If the mileage is a concern, then you might want to consider installing a 3D ignition system. I explored this before switching to the Duratec and heard from a number of people who reported much better drivability and another 3-6mpg. -John Link to comment Share on other sites More sharing options...
stevet Posted September 11, 2006 Share Posted September 11, 2006 No 6. That sounds about right. My old crossflow (145hp) would get low to mid 20's on a cruise, but drop to 14/15 when pushed. It's worth learning to tune the webers so you are getting the best from the engine (and each gallon), plus the looks you get from the neighbors - rubber tube running from carb to ear - can be quite amusing http://www.usa7s.com/aspnetforum/images/emoticons/biggrin5.gif Link to comment Share on other sites More sharing options...
