My dad's friend (long time family friend) just bought a 2012 GT500. It's bone stock and has just a bit over 2,000 miles. He knew what he was buying when he bought it, but I don't think he understood how bad ass they really are till he went online and found out that 750+whp is easily achievable. I knew a fair amount about the 4.6/5.4 2v and 4v engines, but I haven't kept up to much with the tolerances and capabilities of the newer engines. How much boost can you run on the stock engine of a 2012? Also, how much horsepower can the stock engine handle without it being a ticking time bomb? I know these things are very capable, I just was wondering what they will hold up to. Thanks.
