Well i am still in the info gathering phase right now but here are some rough #s. The Powerdyne super charger head is around 2k and i have no idea on the mounting bracket yet since i dont know how hard it will be to build. I can assure you that an install of this type will be much eaiser and faster than the alpine kit. Install should be around 3-4hrs at the most. And you will not have to mess with fuel and oil lines just the serpintine belt and intake. AS for the fan discussion, i have had mine on for a little while and have had better cooling than stock. While my Ax was in the shop the Isuzu tech commented that he liked it and it worked much better than the stock one. I do still have yet to test it in extreme summer heat but i am not worried. I will keep you all posted on the progress.
