It wont hurt your epoxy just your pistons....lol. Make sure when setting it up you talk to someone that can explain how to use alky as your fuel. With n2o some say never use alky get a seperate tank of gas to spary with the n2o. We have never had a problem with alky and that is what everyone in my group uses with n2o. If yopur still thinking about a dry system you might give boondocker a call, their tech support is really good. Im not sure (really not sure it may or may not) how well alky will work with there system. With Boondocker you get fuel by pressurizing your carb and forceing more fuel in but since alky already uses x2 fuel as gas im not sure how well it will work. Call them they will know for sure. I get all my advice and buy all my stuff from GT Performance. PM me if you need his #
