Hi guys been doing some reading about porting,is it true to say that opening a port to much(ie converting an 8 port into 4 larger ports)can actually have problems with flow charactoristics than the standard euro 4 port.Like i was once told that i big muffler on a small powered car can cause back flow because the engine doesnt have the power to push the fumes out all the way.If the inlet manifold is matched to the port size and the injectors are in the middle off the new port will there be any problems with getting the fuel down the chamber.Is it also fair to say that the bigger port will benifit with higher boost.
