Default Boosted Gas Mileage Thread.

What kind of setup are you running on your daily and what mileage are you getting out of it (on what gasoline also).

I fill up with 91 and get roughly 440km/tank ...

440 x 0.62 = 272.8 Miles

and it never goes over 9.3 Gallons or so to fill it (with about $0.75 extra) so that is ...

272.8 / 9.3 = 29.33333 Miles/Gallon.

Boosted D16Y8 daily driven at 6.3psi, street tuned, RC440s, and I drive it how it should be driven.

when i took my old setup, 750cc's drag kit to the beach, it was just over a half tank left on a 125 mile one way, but never got into boost on the way down. once you tip out of vacuum, it was a race between the tach and the gas gauge. i dont even want to know with my 1200's now.

I get about 250 miles per tank with my LS@7psi if I keep my foot out of it. On a good fri/sat night though with lots of cars out, I get about 15-18mpg. Or half a tank in an hour and a half. Gotten as low as 180 miles per tank.

I figured it was pointless to make another thread about this. I'm averaging 25mpg, a little higher all highway and a little lower when it's mostly city or I gave it a couple WOT runs. Why are some people getting such good gas mileage? Are you sure you're not tuned too lean?

I was getting 25mpg last year on Ethanol, RC1000's with twin Walbro's.... with a good amount of spirited driving in the process. AFR's were 15-15.5 most of the time.

it really depends on what transmission you have too. I have a b16 transmission, and drive 80 miles a day down the interstate doing 80mph at 4000rpm sitting around 14.9:1 AFR. my MPG seem to be better in the city where I can stay in lower rpm.

Man...i'm getting 20-22 city and 25-26 hwy on my turbo GSR.





But that's on E85 so all in all, its actually pretty good AND costs $1.91/gal compared to $2.69/gal for premium. If you do the math for mileage lost and money saved, i'm still coming out ahead...not to mention the whole 106 octane thing

I wish it was that cheap here, but i'm not complaining at $1.91/gal either. My gf is a grad student at U of Nebraska so i might be taking advantage of that cheap cornjuice pending a move south...
