Hello, i have a 2006 ford mustang gt automatic with about oh...10,000 miles on it. I have been very satisfied with the power it delivers but recently I've been thinking to go a little bigger. I have made no upgrades on this vehicle so far besides new tires.....I've been doing alot of research about superchargers recently and I have no idea which one will be the best.....Roush claims their new supercharger puts out 145 more horsepower and 98 more lbs. of torque. while Saleen has a supercharger that puts out 100 horse and torque. I've also looked at Ford racing superchargers and according to them i can only get the 400 hp upgrade.....but anyways any feedback to my research or comments would be great...please note that i am a bit of a newbe but i do know what i want....i'd take more acceleration then top speed....any feed back would be much appreciated, thanks!
