here is my situation: I bought the Mustang GT V8 because I wanted a V8 power and sound. Fun times. I did a ton of research, and the Mustang GT is the car for me. I bought it, then took it up to my local track and pulled a 14.8. That is because my local track is at 5800ft. I did not know the altitude would have such a huge effect. It is bothering me. I have this great car with a great engine, but really, if I am honest, I am probably pulling something like 250hp at the flywheel way up here in Denver. We just bought my wife a beater 01 volvo with a 5 cylinder turbo, and I swear, that thing is nearly as fast as my GT. I was at a local road course getting whooped up on by a BMW 1-series. The 1-series has a turbo, so its actually getting much closer to factory power numbers even up high. So, my questions, is there a good, mild turbo I can bolt on that will get me into the 320hp range? I am not looking to push the limits of the engine, just want something that will get me into the performance most people get with a NA 4.6L at sea level. I know there is a procharger mild supercharger, but I am concerned about the loss of low end torque on those.
