as long as your not in boost, you shouldnt use much more fuel. im turbo now and i honestly dont see much of a difference , and my car is running extremely rich!

 

Well my 1st gen hahn turboed neon gets like 28 in the city and 35 on the highway last time I took her out but shes been storaged for sometime now since shes way better lookin and with the engine the way she is I like her in storage . I think 1st gen neons our better for gasmileage than 2nd gens and thats including srt4s also. My acr srt4 was not bad she got like 25 in the city and 30 highway with all the mods I had that helped.

 

From what I heard the Super is connected to the engine by a belt or something, so the engine has to work harder to power the thing. I can't read or write, though, so I might be wrong.
