actually I had a question about the turbo and diameter. I hear a lot of chatter about 3in piping, but most of the test setups that companies design their turbos and test on all have 2.5 exhausts. example is the FI turbo. And they also mentioned that using 3in they couldnt achieve proper functionality and performance. why is that? I would automatically assume more flow/less resistance=better performance. and is .5 inch diameter really going to restrict air THAT MUCH. is it the difference between 500 and 550? or are we just talking a few puny ponies?
