peripheral port port angle or degrees
 

Hey every one. Im working on my first truly solo build. I decided I want to build a peripheral port engine. Im most likely gonna use a 6port engine for the base and of course some upgrades. What I need help with is were exactly to make the ports, size, and the best angle of the ports for best performance. I already have Ideas and theories but I wanna see what other lessons I can learn and apply to my build.
