This is what I dont understand. To my knowledge the roush Supercharger is a terrible buy for the money and the horsepower gaines. They are so milled for so much. Saleen is a great looking supercharger and a great price but after so much you cant up the boost. The procharger looks great along with the the Novi 2200 but they have way to high of boost for the power. Why dont more people put Kenne Bells 2.6L Big Bore on there cars. The kit is more money then most but you can switch out pullies for more boost and you dont have to retune the car. Also it runs at lower boost with more horsepower. Whats the deal with this. Can someone tell me why this is?
