Well i have room in my axiom and in the trooper i looked at, mine will go pretty much where the stock air box was. I will say that my mounting bracket is a little different than most kits but i think it will work well. I do have my stock fan removed but i want to make it so you can install it on a stock engine. I do understand the pros and cons of a centrifugal kit vs a roots style. But the aftermarket blower market is almost split in half between the two styles. This kit will come on little later than the alpine but thats okay with me. If this works it will be listed on the powerdyne application list marketed by me so i am getting pretty pumped about it.
