Yeah, that's a nice supercharger, street legal and fully backed by Toyota...brings a stock 2.4L up to 191HP, that's pretty dramatic...I personally would prefer the super over the turbo, simple design, solid power from the time you hit go to the time you redline, and you generally get much better wear out of a super than a turbo, on the charger itself and the engine as a whole. I read that it takes approx 11HP to run a super since it's belt driven off the crank, but considering the fact that it will generate about 60HP extra boost at 5000RPM (60-11 =49, bringing 142 to 191) that's a fair trade of power I'd say!
Wish I didn't have to buy myself back out of debt before I can get one!
