Powerworks has air to water to air aftercooler (to add more boost safely), & if you can find them a pulley kit to increase boost from 10 to 18 psi. ProCharger is good for peak power, but the roots has excellent power deliver for street.oh thats a lot [wiggle]
which one is better ? jackson racing, or powerworks ?
I know that both of them no longer produce. but wich one is better for the stability and are they diffrent in performance (for example psi) ?
