Hey guys! Just checking in. I've run across several threads posted here via Google searches, and thought I might as well sign up.
My car is a 2008 Mustang GT. Yup, a modern muscle car, and one of the dumbest things to buy if you're trying to save gas. It's a long story how I wound up choosing this over a 2007 Toyota Yaris, so I'll spare you the details. I like both sporty cars and small economy cars equally, while my wife despises "dumpy" cars. You can connect the dots.
Anyhoo, I've got the 4.6L V8 engine, and a manual transmission. I consistently achieve 25-26 mpg (per tank), and on my last tank I managed 27.3 mpg. My only functional mods thus far are a K&N drop-in filter.
My goal is to consistently break 30 mpg with a 300 horsepower brick.
I have just ordered a set of Airtab VGs to experiment with, and as soon as the warranty is up I plan on installing a full Western Motorsports CAI (without a performance tune) just to reduce intake resistance.
I also have a 2006 Buell XB12Ss "Lightning Long" that I commute with when I can (sometimes it's just too inconvenient). My fuel economy on the Buell typically ranges from 48-50 mpg.
