you reply to every thread i am in, lol

ANMVQ · 09-16-2013, 02:25 PM

I wsa around 15-16 MPG with mine :/

Chuck33079 · 09-16-2013, 02:27 PM

With boost and 4.08s, won't you get 0 miles per gallon since you're just sitting still spinning the tires?

brucelidat · 09-16-2013, 02:45 PM

sam at GTM said to expect a 5-7 mpg loss

Baer383 · 09-16-2013, 04:58 PM

I get 24 mpg on the hwy with mine.

brucelidat · 09-16-2013, 05:10 PM

Is that relatively traffic free cruising on the highways? How much did you get before the kit? I would be cool with that, but it's hard to throw out what Sam said, though since they make the kits. I would start a SC mpg thread poll, but I know I will be flamed for caring about MPG, haha.

Cruising down the highway I get that,but trust me once your boosted you won't give a sh!t about gas mileage.

Unless I'm missing something a closed loop map setting should get the same mpg as anyone's closed loop map setting. I get 27mpg straight highway. I should get the same with whatever bolted on as long as I stay in closed loop. My subis were 27mpg also pushing over 330hp to the wheels. Open loop is another story. The fact that your asking about a supercharger is irrelevant, the question should be "with my SC what will my right foot and pedal get me for mpg loss?" If your car weighs the same as a NA car, driving down the highway your mpg's should be identical.

It won't be I can say that first hand.

yes, but my bigger concern was Sam's 5-7 mpg loss estimate, haha. I the traction thing was a big issue, I could just swap out tot he stock pumpkin.

I would think the additional parasitic drag from the blower would eat up some gas, even in closed loop.

Yeahhhhhh

And to maintain speed you need to press the gas pedal taking it off the closed loop and since you're S/C vs Turbo'd you'd have to burn even more fuel to turn the SC (right?)

Oh, and synolimit, your Subarus are turbo'd, very different beasts

Chuck33079 · 09-16-2013, 10:16 PM

You'd still be in closed loop at part throttle, but you're right on the rest.
