I know also, and many is overdriven too, maeby he ran it with too high rpm or had too heavy pistons and rods. With overdriven set up, it will like to run higher and higher. I have blowed up one sbm with 6-71 turning it up to 15% over and 9000rpm, bearings didnt last that couple runs. I'm happy that the crank and the block did.
About twin blower setup, cant say anything good performance vice, if the are not sync they just push air around intake. Just put one big one or one small twin screw and start enjoying it.
