im installing an aftermarket turbocharger but i dont know the specs on how much psi the stock intake manifold on an 03 ranger edge 3.0 6c can take. if anyone can help me please let me know the info. minimal setting on the tc i want to get is 8psi but i want to know if the stock can take more boost than that max output on the charger states 480hp i wonder if the stock manifold can handle anywhere from 8-16 psi. please if anyone has info please post!
