Brand new to the forum as well as the new owner of a 1998 Chrome Yellow GT convertible. I bought the car off of eBay from the original owner. The car has 14,000 original miles on it. The car looks and runs like it is brand new.
When the previous owner bought the car he shipped it to Steeeda. They modified the engine and suspension. I have cut and pasted what was done to the car below:
35th Anniversary supercharged Mustang GT convertible, 5 speed manual transmission. 17,600 miles, one owner, always garage kept. This car is as close as you can get to new for a 13 year old car. Car is chrome yellow, with black convertible top and dark charcoal leather interior. Boost pillar gage and shift light have been added. All power, air and Mustang factory 460 radio, with cassette and cd. The engine is 4.6 V8, single overhead cam, with Vortec S trim supercharger, making 12 PSI at 6,000 RPM. The supercharger is also equipped with a Vortec after cooler. In addition to the supercharger, the car is equipped with a 90 MM mass air meter, 77MM throttle body, 40 lb fuel injectors, power pipe air inlet and K&N filter. A STEEDA short throw shifter has been added. The suspension has numerous upgrades to include cross brace kit for engine compartment, upgraded frame braces, adjustable strut braces and STEEDA rear control arms. The exhaust has been upgraded to 21/4 stainless steel pipes, flow thru Cat back catalytic converters, and dynomax mufflers. The ring and pinion has been upgraded from 3.23 (factory) to 3.55 posi-traction. The car is also equipped with 17 inch chrome Cobra R wheels. Front tires are Kumho Ecsta Supra 255-40-17 Z and rear are Kumho 275-40-17 Z. The original Mustang wheels also come with the car. All work was professionally done by STEEDA Racing. On the dyno the car makes 402 horsepower and 403 foot pounds of torque. The undercarriage and engine compartment are just as clean as the rest of the car. This is a fun, and easy car to drive. The car is fast and a great buy.
The car is everything he says it is and more. My question is 12 psi of boost too much for this set up?

If that is a stock motor not forged then the answer is no. Stock internals cannot handle that kind of pressure u will end up cracking a piston if u run ur car hard after a while. Timing is important but the overall compression will be ur problem. I am speaking from experience.
