Well it looks like i am keeping the fit no one wants to buy it. So i am more than likely going to do one or the other not sure which yet. But was woundering what is ur MPG with the turbo or supercharger thanks for any input guys

 

turbo will yield better mileage over s/c

 

exactly.....supercharger is driven from the crank and takes hp even when its not making hp....stay out of boost with a turbo and your mpg will remain the same.

 

I plan on boosting mine this summer. But I am waiting to see if gas prices go over $5/gallon first

 

I have had turboed cars before i know if i stay out of boost it will get them same. I am trying to see what a fit gets when its in boost so some one that drvies there car in boost alot chime in please. I hear the SC fits get around only 3-4 less MPG than they did when they were stock. So i just want to see peolpe who have them tell me what they are geting. thanks for the input.

 

I've been getting within 1-2 MPG of my pre-boost averages.. which to me is pretty damn amazing since I'm certainly not shy of teh booost. I got 33-35 in the city before boost, and now I'm getting 30-34 according to my last 4 tankfulls. WOOT!

 

My best tank on the Base KW kit was 41mpg. I avgd about 36-38 religiously.... i am now at 12 psi and am avging about 34mpg.... thats with big 310cc injectors. If i mash all the time... thats a different story. When I was at 8psi I did a canyon run and still got 30mpg on that tank.

 

BTW this guy gives nothing but bad info lol.

 

u can take my car for an example
07 fit sport AT (really trying to juice it)
380km-400km per tank before turbo
300km-320km per tank after turbo
here u can c the difference

 

when i first got the HKS kit on, with the tune that is come with i did 34mpg highway.

 

It depends on how you drive.

If I drive hard (boosting a lot of the time) I see about a 10-15% decrease. If I drive like a granny and try to stay out of boost, I don't see any decrease in mpg.

 

So, I fixed my rich idle problem a few days ago (some of you will remember my battle with 11:1 AFRs at idle).

Well, long story short my gas milage has jumped another 3 mpg!

Which makes sense, I guess, as I'm not spewing all of my 94 octane goodness all over the pavement at every stoplight, but it sure got me excited! Especially with gas being down to $2.19 here.. my gawd it's cheap to run this car!
