Just wondering what kind amileage my fellow bro's and sises get on their singles. I have a t04s and get around 13-15 on the highway. Not too sure about street but I would say ~12.

 

I got about 21 mpg on my 1993 T04S on a several hour highway trip. I get about 10 mpg around town since I'm usually boosting a lot more. I've found that in general I get MUCH better mileage on a long trip on the highway (say 2 hours+) compared to short highway trips of only 30 minutes at a whack.

My 87 TII gets about 13-15 on mixed city/highway and around 22+ on long trips.

O man who knew. That 12-15 only holds up then on a short trip. I did take the highway for aobut 30 min when I calculated that value. Okay, I guess I'm not that bad off .

BTW, what do you usually get on short trips? Also what is your setup?

 

wouldnt lowering the boost when you dont really need it increase your fuel economy?

 

Well yeah, if I could lol. I have no way to control my boost in that fashion. All I know is that I can't boost above 10 psi due to the spring rating on my standard HKS wastegate.

 

Hell I get 12 with my twins, 18 on long trips.
I burned a whole tank in about 40 minutes at Laguna Seca :-D

I get about 12 mpg in mixed driving, but it's mainly stop and go crap.

 

I'm gonna stop feeling sorry for myself. I was getting about 16 mpg in town and 19 highway and expect the mileage to get better with the new rebuild.
