hey fuel consumption..
 

hey im only getting 240ish K's out of a full tank in my GC8... is this normal? - I use to own a white gc8 wrx 1BHU-355 and that would get around 380ks... any one know if theres somthing wrong or if my fuel tank is tiny or somthing...

More info?
How many litres does it take to fill?
Mods on car?
Got a bov?

Do you thrash your car or what? I get 150kms before its hit the 3/4 mark on the gauge...usually 550km for a tank in mine. No mods

More info would be great. Fuel economy is effected buy a few things. Your driving style, city/ country driving, mods, faulty parts such as air flow meter, o2 sensors, air filter blockage, air leaks, tune even tyre pressures and wheel alignment

thats bout right for me going all out at collie froma full tank :S
do you have a bigger fuel pump or big injector or atmos venting bov?

Sorry didn't read what I wrote :)

Orly?

Regulator holds pressure nothing to do with fuel volume or fuel consumption, plus it's at the end of the fuel rail after the injectors....

The tune & the injector duty cycles it produces directly affect the consumption.

A dead oxygen sensor or Ecu water temp sensor will cause it to run rich all the time & drink the go go juice.

A dead AFM causes lean running & awesome economy (whilst it's parked for a rebuild) :D

I have an atmo bov, 272 cams, I run 25psi.......I still get 400-450 km on 3/4 of a tank, average fill is 45 litres = 9-10l/100km approx.

Is it tuned? What ecu?

Sorry didn't read what I wrote, yes fuel pressure reg only regulates pressure, ecu controls fuel quantity
My bad
