just was mentally going over this and curious if there is any difference in the engine or an effect on compression. let's say you have one turbo that makes 300whp at 10psi and another that makes 300whp on the same engine at 15psi. is the turbo being operated at 15psi any harder on the internals of the engine or is it basically the same thing since a similar amount of air is obviously there which is proven in whp or does the actual pressure have an effect?
