Ok... So I have thought about it and there is something called a Hot Flow Bench that turbo manufacturers will use to see what kind of air a turbo will move at set pressure differintials by doing this they can tell you at what psi it will make the coolest air charge and how much boost it is capable of to check its effeciancy and anti surge capabuilities, I guess in theory you could do this to a N/A motor to simulate boost for a turbo and then the same for a blower on the same motor, All things being the same open headers on a dyno there should be no back pressure for either motor. With that said, At a 1:1 pressure differntial the turbo motor is making more power with its spent energy than its using to make it And a blower motor makes alot of power only using some to produce it either way your making more power than you started off with and making alot more that is using to make it. I personally like turbos better but dont have anything against blowers either, If blowers were not so outragiously priced I would have one by now ( I hope china is listining ) In my first hand exsperiance turbos come on alot harder (tourqe wise ) than a blower of the same boost level most blowers keep coming with the rpms where a turbo comes on early and stays there. Sorry if I seemed bent out of shape but I feel like were beating a dead horse with the whole back pressure thing.
Joe,
Sorry about the spelling but my computer at work wont let me download the spell check.
