if you are looking for cool factor, the blower is the way to go. the instant throttle response and the sound are both awesome. Turbos on the other hand are free horsepower. a blower may give you an extra 300 horse at say 10 lbs of boost, but its using 80 horse to spin it. the turbos would net you 380 horse at the same boost level.(using no power to spin them. Plus the turbos quiet down the whole deal quite a bit. Also, they are easier to effectively intercool, ie cheaper). a water to air intercooler using raw water could give you an air intake charge that would only be about 10 degrees above the actual water temp, even at 10 or 15 pounds of boost. Thats where the real horsepower numbers come in. intake air temp with a blower at 15 lbs boost will be around 250 degrees, as the roots type blower makes alot of heat, however alchohol cures that issue right quick. hope that helps.
