i have a question i have a 98 auto mustang gt. stock the car runs a 15 in the quarter mile.

now i have added a 8psi supercharger(powerdyne) and a superchips computer programmer flowmaster 40 series mufflers took off four of my cats and have msd ignition wires. does anyone have a guess what my new quarter mile time could be maybe high 13's?

with your mods you should be capable of running high 13s. I would HIGHLY recommend getting a REAL dyno tune it can make TONS more hp/tq and your car will be safe. With the tune companies throw in you can risk blowing you engine up and more. A tune is a wise investment to make.

Current Mods - Off Road H, Flows, 4.10s, Shiftkit

PI heads are the cylinder heads ford used on the 99-2004 mustang GTs, better flowing, and better cam profiles... the heads/cams (and their matching intake/exhaust) are the main reason the 99-04 GTs are rated about 40 HP higher than the 96-98 GTs
