  • Will a turbo kill mileage?

    Thinking about sticking either a turbo or supercharger in the old workhorse. A buddy a mine who owned a 97 RS told me it would cut my gas mileage in half, because "more air intake means more gas consumption." If that's so, then why do cold air kits claim to improve fuel economy?

    Anybody got any ideas?

    Gas mileage is 50% car and 50% you. It all depends how you drive. People told me my 4.10 gears would kill my gas... nope, then they told me the cam would kill my gas...nope. I baby the car so I get around 27mpg in the city. As long as you stay out of boost on a turbo you should get the same mileage, maybe a tiny bit worse if you have bigger injectors and such.

      i have heard from those with turbos that it will actually increase your mileage as long as you stay out of boost.

        As long as you are not "on" it 24/7 you should be fine.

          A turbo will take your engine's effeciency way up, and a effecient engine gets better gas milage, now when you stand on it im sure the added fuel intake will kill you but as long as your not on it all the time you'd be fine

          You should talk to the guys in the FI section, they can tell you from personal expeirence, but they'll probably tell you that if you have to ask your not ready to turbo, you should go read up on FI for about 2 months straight, then consider it

            also the car wont be so underpowered, which will help with mileage, also it depends on the size of the turbo, if it spools really fast you'll be in boost more meaning more fuel is consumed, something that doesnt "really" spool until you put it to the floor would be ideal for mileage

                Here is a method to cut your gas mileage 5%. It is already incorporated into the Prius and will be in new cars.
                When you get to an intersection you know will be a long light...TURN OFF THE ENGINE. When you are waiting for someone at a shopping center, airport, train station....TURN OFF THE ENGINE.
                Some guy here in Florida last week stopped at a 711 to get something.
                He left his SUV in the parking lot with the engine running (burning $3.00 gas)...some young guy jumped in and took it. Fortunately the police caught the guy and recovered the guys SUV.
                If you burn gas only to make the car move forward, you will burn less of it.

                  yea but then you use other components way more than you would normally. my idea, COAST. use your brakes as little as possible, because all they do is reverse the process of accelerating aka using gas.

                    I suppose turning off my engine might help my mileage, but I bet it'd kill either my starter or my flywheel. I think the guy earlier had a point when he said use the brakes as little as possible, and coast as much as possible. Does constant use of cruise control help?

                        you can probably do a better job than the cruise.
                        turbos were invinted for diesel fighter airplanes, in WWI, specifically for long distance flights. if you have very very little boost it will help gas mileage.

                          they were invented before world war I, and their purpose was to give planes higher altitudes. at higher alts the air is less dense, but the turbo crams it in.

                            Yes, and not only that, but keeping at near-constant speeds helps.. such as when cornering.

                              yea, that too, I had the article on it, but my room looks like a mechanic's room. ;)
