HAHAH 300hp on stock internals and 10psi annoy no way the stock engine can't handle that. Unless he has his fuel and timing tuned to the T even then don't think he will be making 300hp. Pretty much the setup i have can be anywhere from 190whp-220whp at 8psi depending on how well your engine is before you turbo it.
