My '07 GT is still supercharged. Vortech standard V2 SQ S-trim with standard pulley (3.8"), 4800 rpm stall converter, 4.10 FRPP gears, BMR driveshaft loops & rear tunnel bace, SLP line lock, SLP catted X-pipe, 45K volt coils-on-plug, FRPP 3V0 spark plugs, UPR oil seperator, FRPP strut tower brace, etc. A couple months before I traded it in, it put down 393 rwhp on a Mustang Dyno (would have been about 415-425 rwhp on a Dynojet Dyno), and last fall I ran an 11.79 and a pair of 11.85's in the 1/4 mile on drag radials. It has nearly new 255/45/18 Continental Extreme Contact DWS tires, slotted brake rotors, ceramic Hawk brake pads, and Optima red-top battery.
Car is in excellent condition and has just 28K miles on it. Engine oil was changed every 3K miles, trans fluid has been changed a few times, diff fluid has been changed once, fresh spark plugs just went in a couple hundred miles ago. Our dealership's service department did all the installs (including the supercharger) and it was custom dyno-tuned by John Garner at the HorsePower Ranch (just outside Seattle) with a very conservative tune (as it was my daily driver). I bought this car brand new in October '06 and have all the service records for it.
The V6 Pony Grille was an easy install in my GT bumper. I snipped off the V6 mounting tabs and made my own mounting plates (concealed them under the radiator cover so nobody can see them. As the V6 grille is slightly smaller than the GT opening, I used marine-grade, black weatherstripping to fill the gap. The weatherstripping is the same texture and color as the grille, so nobody can even tell it's there unless I point it out and they look very, very, closely.
I can't believe our dealership has dropped the price on my '07 so much ($21,950 currently). They are going to lose money on it when it sells at that price! Kelly Blue Book "private party" value is $23,100, and that's without any of the mods! Trade-in value is just shy of $21K w/o any of the mods. This is just too good of a deal to pass up for someone who's looking for an 11 -second S197 GT that wants a daily driver.
