When i put the procharger on, can i expect it to decrease MPG as expected or will it act like a turbo and actually increase MPG?

I cant imagine pushing out 350+ hp on a regular basis would increase MPG. From things I have heard if you drive your car conservatively you can maintain your normal MPG or close to it. But romping around all the time wont help at all.

well yeah of course, but that works the same with a turbo, if your WOT all the time, you can expect to WOT to the gas station. but just reg driving. and you said not much of a difference so thats always a good thing.

oh.. and i'll be pushing 500+, but just wondering about the application of it in general.

Ya I dont know what the procharger adds to a cobra so i didnt want to go overboard on HP. But 500+ is a nice number when you want to shut down some ricers. What kind of mileage are you getting now?

disposablehero27

well i actually dont' have to good of an idea, the speedo has been off for almost two years now from the 3.73 install, and i just went to 4.10's... so i'm not really sure, and if i put the procharger on stock it'll be 434hp, but i'll have alot of work done to it before she hits the dyno.

i have to get that dallas speedometer calibrator soon. few more weeks and she'll be dialed in.

How far off is your spedo?

disposablehero27

it depends on how fast your going.. the 3.73's but an extra 7-10 on it.. the 4.10s are anywhere from 4mph-21mph. at 95 i'm going 75 and 50 i'm going 30 something.. i can't remember.

yes, with just normal driving, your MPG's will go up.

Superchargers make the engine more efficient. Add that with good tuning and you can see as much as 2-3 MPG gain.



provided you keep your foot out of it.



When I RoushCharged my 5.4 3v in the F-150, I saw a .5 MPG gain. But then again, I was in the boost alot. When I kept out of the boost and drove like a sensible person, I saw almost a 2 mpg gain
