it's the mating of the CF plenum chamber to the aluminum base. as I said, I love that design also, but it could use some improvements for a boosted motor. if force is equal to the pressure times the surface area, then imagine what kind of force those horizontal surfaces might see at 10psi? 20ps? 30psi? I don't know what type of surge tanks you have tested, but typically CF pressure vesels have an an AL core. Crossectional shape also effects how well the vessel will hold pressure, so a cylinder will hold much better than a box etc. I'm not saying it can't be done, just that it would need to be very beefy, and due to the nature of CF, where (for the parts an average person or shop would construct) there are a lot of variables not strictly controlled. How sure are you of the resin content, how will the resin react when heated, etc. there are many things that could lower the strength of the part, and other than Nixit I doubt many of us have the knowledge to calculate what is required, nor the ability to fab it to a standard where the calculations would be accurate.
