I own a TII, 98000 miles, 25 HWY

 

42 MPG in mixed driving.

Oh wait, you mean the RX7 XD
Last time I checked it got 19 mpg, that's driving on very steep mountain roads redlining multiple times every day. (Stock S4 13B, 5 speed)

 

not enough... gotta pay to play though

 

Just got 20 average this tank.

Only thing I'm not looking forward to with my Turbo engine swap/build is the decrease in mpg.

But it will feel soo good to step on that peddle
!

 

my car seems like it is running fine and I can barely get 200 miles on a tank. 88 N/a vert with no mods but RB headers. I think I may need some spark plugs maybe? it has been a while...

 

70 bug with cosmo 13b-re. Stock ports, 11-13psi, microtech, running super rich 11 to 11.5 afr's on WOT pull, premixing, 91 octane, methanol spray above 6 psi, stock twins. Getting 8 city, 12 freeway. All miles are hard miles, smashing throttle every second I can

 

I have two s4 turbos one with big streetport, 3mm seals garrett to3/o4 with 1600cc Indy injectors run by microtech ! I'm lucky to get 250kms from a 68l tank! Round town and highway! Excuse the metric I'm an Aussie ! It's running that rich it makes your eyes water from its stainless 4" single exhaust with no cat ! tough , and is constantly afterburning fuel and shooting up to 3 foot (there you go) flames ! Love it ! Worth every cent . I wish I could afford $120 a day to constantly drive it! Te other is a streetport with a hiflo s5 turbo and stock ecu ! Dual open 3" exhaust! And I get 300ks for the same $$! Expensive but worth every cent .

 

I have no clue but Ive gone about 72 miles on a quarter tank. Just got the car so its all new to me
