It looks sharp, but why is there no inter cooler? Compressing the air makes it hot. Hot air is less dense, kinds defeats the purpose of compressing it. (Well partially, at least) Thats why most serious turbos / super chargers have an inter cooler.
It makes me think this wasn't done for power, it was done for looks and bragging rights....
One bad thing about those roots superchargers is that they get heat soaked very easy. After a couple of hard pulls that thing is going to be HOT. probably the only type of intercooler you could put on that thing would be water/meth injection.
