I had some extended brackets fabricated to allow the chamber to not rotate down towards the tank as much. I did not have to dent the front side near as much and it still had clearance from the hood. I also had to dent the section next to the hull right past the coupler a little. It has been running on the wifes ski all summer and no problems. If you run it hot, the power rips and it sounds trick. I have another chamber that I am going to try on my 760 SJ as soon as I can get some more brackets made up and get my old headpipe screws refitted with the pardaddy oversize adjusters. :woot:
