how much power will under drive pully put out
fox body mustang bone stock..estimated how much horse power will underdrive pullys, cold air intake, and full exhaust get me? any other ideas on starting to building a more power? not looking for a drag car or anything like that i just want i little more power in my pony? maybe like 400-500 hp
Those will add maybe 11 to 15 HP...maybe...If you want 4-500 HP be prepared to spend some big $$$..new heads, intake, E303 cam, headers, mass air and throttle body fuel injector upgrades, super charger, the list goes on. You'll always be working on it unless everything is set up just right. Also you'll never get your money out of it when the time comes to sell and people are hesitant to buy modified cars anyway. If it's a nice, stock 5.0 my advice is leave it that way. It will be worth more if left bone stock. Just my opinion.
Right, over 300HP and your into serious money. Throw the underdrives on, bump the timing a few degrees, add some rear gears in the back differential 3:73:1, some subframe connectors, and a catback exhaust, and you'll have some more pep around town. Always keep your car tuned up and it should run great.
Tom has it correct but just a word of warning before you put in the 3.73 gears make sure the torque boxes are in good shape. These are a weak spot on the Fox body.
