If i were to put the vf34 with sti pink injectors and an upgraded fuel pump with an up pipe and turbo back exhaust then get a pro tune and run 17psi what should i do in the 1/4 mile and if you have this setup how much miles per gallon do you get

 

roughly in the high 12's to low 13's depending how well you drive

 

thanks but what about a wrx with just an air intake and up and down pipe

 

well in the 808 i have no clue

but if i drive all highway on the mainland i can get 340-355

 

Well I have a 02 wrx with turbo back and a up pipe with headers and a bov and I was running a low 14 but I had a bad boost leak.

 

i wish i got that much miles per tank but i only get like 230-240

 

who cares about gas mileage wen u have that set up man its worth the loss!!

 

I have a vf22 setup in my 03 wrx and I did a 12.9 at an altitude of 2500. I'm not sure how a vf34 would compare to that.

 

How much boost were you running

 

19psi and on 103 race gas.

 

340-350? even at stock i never got that kind of mileage!

 

/\ that's gotta be highway mileage...I'm running a VF-34, STi Pinks, Helix catted DP, UP and an Apexi GT Spec exhaust with HKS intake....I'm lucky to get just over 300 per tank.

 

LOL! ****... i have vf34, pinks, walbro, catless dp, up, header, catback, shortram and inlet hose with RA gears and now im lucky if i get 250 a tank

 

if you stay out of boost, a bigger turbo will actually INCREASE mpg by virtue of better VE due to lower exhaust backpressure.

if you can drive it, high 12s are not impossible. hell, down in puerto rico they're running high 11s on vf3x.

 

stock i got 370 once

granted i put in 15.2 gallons

but i hit it

yes these numbers are ALL highway
