Supercharger and MPG
Do any of you notice a MPG drop after installing the supercharger outside of when you're really getting into the machine? I'm curious if the drag of the charger belt affects this much, or, if like a turbo system, the difference is small when out of boost range.

Me too. I get 13 in the city, driving mellow, or hard. I got about 17 before the blower. It gets about 23mpg on the freeway.

I have 3 2005+ Mustangs, 1 with a Procharger HO Stage II kit, 1 with the Paxton Novi2200 kit, and 1 with the Impulse Garrett TWIN TURBO kit.
Of of these things SUCK GAS! All of these cars have stock t-bodies and JBA shorties (except the turbo car obviously) and no cams.
The turbo car actually gets about 14 around town. the blower cars get between 10 and 12. And when your foots in it, all bets are off. I ran my car at Irwindale Speedway on the outer over to inner oval drift track for an entire weekend. My dash said .8mpg average!
Good luck! ;-)

Significant drop in mileage, even when out of the throttle. From 18-19 in the city to 14-15. Depends on the traffic you drive in too, stop and go is a killer for economy. If you can cruise at a steady rate it's much better.

I'm not super concerned about MPG in general, but I am the type that enjoys power, but can manage to stay out of boost for the majority of my driving. My dads vehicle, a pretty heavily modified BMW 335, still gets great mileage despite being pretty far from stock. I realize that its a 6 cylinder and that helps tons, but was curious if the MPG loss from having to drive a belt all the time for the supercharger was significant. I am more experienced with turbocharger cars, and should I pick up a Stang, I'd probably be leaning more towards the Hellios (or whatever its titled) system.
My current car gets about 28 hwy and 18-20 city, however my car before that, a 66 gmc that I fuel injected, got 10 reg, 14- hwy, so having a car in the middle wont hurt me too badly.
Any years that fair better for FI than others on these Stangs?

The spark plug issue with the 2005-1st half 2008 mustangs would be enough to make me get a 2009+. The spark plug issue is with 2-piece design in the plug that is prone to breaking in half when the plugs are removed, leaving half the plug stuck in the head. There's a process to get it out, but I'd MUCH rather skip the possibility of that every happening.
In the 2nd half of 2008, ford switched spark plug & head designs so that this isn't an issue anymore.
