Definately NO BOOST with hypers. You might as well just skip the assembling part and go right to "rebuild with forged", because the process of setting up a boosted engine will destroy them. They can take the pressure, they cant take ANY, and I mean ANY detonation. Evrything has it's performance window...that's the end of hyper pitsons'. I have sen too many mopar blocks broken from that, but they use long rods, so the ends just slam around in the bores when the piston reverts back to powder... 4.6 Fords are just tossed away...
