I recently did a bunch of upgrades to my Turbo II (safc, new turbo..etc..), and amazing I'm getting about 50 miles per tank MORE than what I had been getting.

Usually about 260 Miles Per Tank, these days (whereas before I ran out of gas at 220)

Wondering what the norm is.

 

I usually get between 220-230 mpg with just an intake and exhaust.

 

I get about 130-150 miles per tank.

 

I'm not sure, because my gauge is broke. But I normally refill it at 200 miles.

 

11 mpg!?!?! I get 240 & about 220 with A/C, about 17-18 mpg.

 

kinda off topic but how big is the fc turbo 2 gas tank? i have a half bridgeported motor in mine so i know its gonna suck ***. and using premium doenst help.

 

16.6 gallons for S4's? I think thats what it is.

I average 150 miles a tank. Running on the rich side though.

 

dam you guys i average between 280-300 miles per tank.... most i've ever gotten was 315 least i've even gotten was 200.

 

With a bad O2 sensor I got 280 mile to the tank. 0_o

I usually get 315 or 320 to a tank. But I have an N/a. :-/

 

Ok, you N/A guys dont count.

I got 150 miles on a tank, with bad spark plugs, old O2 sensor, old fuel filter, nasty fluids (oil, tranny, coolant), and some other crap.

I've done all that stuff, but haven't driven it yet on a full tank.
I filled it up about halfway, and got close to 100 miles if I remember correctly, somewhere like 80 or 90 miles.

Your are probably seeing better fuel economy thanks to your SAFC. If you boost for the majority of that tank, it will be in the mid 100's

 

I'm getting 230-260 miles off a full tank and all I have is an intake. Everything else is stock.

 

i get about 13-14mpg after a put an hks intake kit on it.

 

lol yea it kinda sucks. But again, l am vacuum leaking a bit so its causing a bit of a rich condition. But I dont think the injectors and fuel pump help much either.

 

i get anywhere from 250-300 in my s5 n/a.

 

240 - 280 with all my mods and a light foot

 

Sure we do!
