Supercharger and MPG - Page 2

So buy a 2005 to 2007 and change out the spark plugs to the single piece Brisk Silvers. Problem solved and save some coin. Otherwise, your power adder options are endless. If you have the extra $$$ go with turbos. Single or twin doesn't matter. More torque and more horsepower. Turbos negate the fight between twin screw and centri superchargers.

(In my best Mr. T voice) I pity da fool who's askin bout mpg and forced induction!

Seriously though, I'm averaging in the 17's combined. Highway only will get me about 21-22.

I average 12mpg. 100% city driving short trips. I've had it out on the highway once since I put the blower on and it got 22mpg.

I drive about 50% highway 50% city, and my average before the s/c was about 17-18 mpg, now it is down to about 16-17mpg. Nothing reall significant, but like they said if it crack into it a few times, it is a huge drop, but that's to be expected

Approximately 20 on the highway
about 17 in the city.

before the blower I was getting about 25 on the highway
and about 21 in the city...

At times I have a problem keeping my foot off of the gas and get about 14-15 miles in the city 17 on the highway...moderate driving.
