t-bolt clamps dont hold any better then worm clamps up to about 32 to 35psi , If the piping is clean and you use good hoses then you dont even need a bead role and everything will hold with STD type worm clamps
What yu should be asking is , how much will the turbo safely make before just pumping a lot of hot air , and how high can I go with the tune you have ?
From what I have seen from the roush turbo is it is ver limited to about 19/20psi , it will go more then that but it starts dropping off fast
