  • 3.8L FI gas milage

    Yeah, so i have seen the gas milage of 3.4Ls on turbos, but what about 3.8L? Right now i drive my car pretty easy, unless i am racing, i shift ever gear at 2,500 or lower, especially when i get to 4th. Anyways i get 20-21 mpg all streets, and no freeway. Once i throw Tiagos kit on what should i exspect to get, asuming that i drive the same? And what would the procharger kit net me?

    a few links down the exact same topic was posted.
    its under the name "Fuel milage while boosted?". . basically though mileage wont change much until your car comes under boost but the turbo will definately get better mileage. i have only heard good things about that kit on this board. also try checking under the turbo kit questions link also on this page they may have more on the mileage in there. another thing to try (and i dont mean to be a prick) is to do a search. the search on this page works very well. i hope this helps

        Search. Shouldn't change much unless you're hitting the boost ... so you'll probably average a little lower, but cruising on the highway should be no different.
        I opened up my exhaust a bunch, so I expect it to go up some.

          as everyone has verified, gas mileage wont change until under boost.

          for example, and for comparison:
          the buick grand national still gets like 22mpg on the highway, and can cruise at 100mph without the turbo spooling. but get it into boost range, and your gas is affected.

            Yeah, i know about the turbo, but what about supercharged?
