Agreed! NO reason to DISPARAGE ANYONE... Livernois is an excellent company.. they may charge more than you think is fair... but they are what they are because they know what they know and they know what it costs to do things their way.
However, If one would install a Devils Own kit, complete with tank, controller and braided lines, it probably could be done for that price, provided you didn't have to remove the front clip. If you have a custom CAI like 4DR had or like I have, there is room for the pump below it, and the tank can be installed above pump somewhere inside radiator, and not restrict air flow. It would also take someone who had done this many times...
I might modify Torrie's system to do some or all of this. But.. if you are mostly looking for power for short bursts, or serious strip time, Torrie's system works fine, you just have to make sure it is primed if you are running long wot runs, like at the strip. Honestly, I never saw any time I didn't have spray, but like everything... S...T happens... even with Alky Control controllers that Livernois sells!
