Default mpg question

i am currently getting 24 mpg in my 89 lx coupe with BBK 70mm tb, long tubes, H pipe, billet underdrive pulleys, k&n filter, taylor wires and super 40's, my question is if i put an electric fan, electricwater pump and a 5-6 psi s/cwill my mpg's increaseat all?
Thanks.

The mpg that you are getting right now is pretty damn good. With a blower you will definetly see a decrease in mpg as your car will deamnd alot more fuel.

With a blower you have the option of staying out of the throttle which will not make the engine demand muchif anymore fuel then a non blown motor. Stay out of boost and you gotdecent mileage. But when ya got the power on hand staying out of it is much easier said then done. You may find yourself passing more cars then normal.

Even when your off the boost because you will be running bigger injectors.

I've never seen 20+mpg, i'm lucky to get 15 most of the time (lead feet run in the family, 47 tickets and counting)

Stock and in good shape the cars are good for 20+ mpg. I regularly get ~25 on the highway aslong as I'm not going faster than 80 or so.
