has anyone actually had any experience with these superchargers? it looks like three starter motors connected together. they say it can be used in pulses( i would imagine so the starter motors don't overheat), and that it can generate up to 100 horsepower. and it is a fairly universal fit. seems to be legit. just alot of added weight. i think you have to add a couple batteries. just wanted to get someone elses take on it.
