You should get the idea of decent milage out of your head before even thinking about building a quick NA rotary.
Tuned well you MIGHT pull low teens on the highway.
My street port (very poorly tuned and driven hard) get almost unbelivably bad milage.

Round town you will get 8-10mpg if you drive conservatively.
On the highway its really ecomomic, around 12mpg is typical.
As for on the track, why worry if you get 4-5mpg while having fun.

Really? I used to get 12-14mpg normal driving for a full bridge(but not cut into water jacket). And for a long drive(as annoying as that was to drivewith the uneven engine running at part throttle) I got as high as 19mpg. 50dco weber-long tube header and medium flow muffler. Bridgeports should only be used for track use and weekend warrior driving because of the noise IMO

I get anywhere from 9 around town in cold weather to 22 on the interstate at the speed limit, steady cruising. 1/2 bp-1/2sp, with a Mikuni. The highway mileage was driving from fill station to fill station, no stops in between, so that's probably the best it's gonna get.

I drove around with just my header for 2-3 weeks once just for fun. never got pulled over just throttle down when you see a cop.

I don't mind the noise at all, but the neighborhood I live in now, it would be too cop magnetic. I went to a steetport blowthrough turbo and now I have more power and less noise- win win!
