Boost and MPG
I was just wondering what kind of gas mileage supercharged you guys get. I currently get 14mph with a mix of city/highway. My setup is as follows:
-Vortech HO
-Manual
-stock 3.55 gear

I have the roushcharger on my 07 GT and get about 18-19 with mostly city driving. When I go to my parents its mostly highway/back roads (no stop lights) and get in the low 20's. If I keep the boost out when the lights turn green I get better mileage, but thats doesnt happen offen...

mine's about 13-15 in town (auto trans), and 19-23 freeway. Went down about 2-3mpg in town, and 1-2mpg on freeway from how it was before the whipple (4.10's, intake and tune)

My daily driver tune is 430whp. You are putting out a lot more tq than I am. My car only put down 383 ft lbs of torque on a dynojet.

Could be supporting mods----alot probably is dealing with the tuning. Are you running canned or dyno tuning?? What all are you running?

I get about the same mileage now , that is when I don't kick it , as I did before I got the supercharger. I don't do a lot of just city driving , but combined city and highway I get about 16 mpg during the week. On the Highway I get about 21 mpg ...

I get anywhere from 16 to 20 mpg average between city and interstate. If I do primarily interstate driving at ~70 mph, I'll average 21-23 mpg.
Short lists of mods are:
Vortech s-trim @ ~11psi
Paxton intercooler
FRPP delete plates
Pypes offroad H with resonators
Borla axle pipes and mufflers
FRPP 4.10 gears
Fuel system is stock Ford pump with a KB BAP; 39lb injectors.
I run only 93 octane. Timing is at 18 degrees and with stock tires on Brenspeed's dyno pulled 469/414 earlier this fall.
