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?

Silex

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.
