Default AC and Gas mileage

I know that my PT is not the normal GT (2001+Hahn), but, My gas mileage sucks when I run my AC. Almost 50 miles less a tank with AC running. I normally get anywhere from 250 to 280 (colder weather)per tank, and barely 200 with AC blowing. Anyone else have similar results? [:I] In DC so the humidity is bad and I needs the AC!

Around town, I find little difference in mileage between AC running and AC off. On the highway, AC will drop the mileage somewhat but running with the windows down will lower the fuel mileage just as much due to increased drag and buffeting.

AC ain't free. It sucks a lot of power to turn the compressor.

4 cylinders pushing a 3500 lb refrigerator. It is a lot to ask. We get about 22 to 25 mpg with ours. I wish it was better but I can live with that.

I get 22-24 mpg in my 5 speed GT with or without the AC on. Don't really notice a loss of mpg or power from the AC. I am running far more hp/torque than stock so it doesn't take much to get my GT moving. I do run pretty easy with AC on, too. How do you like your Hahn? I've heard nice things about those. Upgraded internals and intercooler. Nice. What boost are you running? I have a dual stage BC and am running 15 on 1st stage and 18 on 2nd.

Still running 6psi, but, planning to get Greddy BC to raise the stakes. I really like the system and it is a blast to drive. Still working out bugs in other systems so may have to delay the BC for awhile. Thanks

I get 260 miles to the tankful, running it down to the chime. AC makes a difference, but well worth it in DC summers!
