[QUOTE="TwizzleStix, post: 1618325, member: 32095"] It means I'll have more turbo/airflow than required, such that I can set the tune any way I want without worrying(too much) about the boosted air temps and/or exhaust manifold pressure causing detonation and ventilating the block. Turbocharger compressors are great to provide boost to the intake side, but in doing so, the turbine also creates a high pressure in the exhaust side. If pushing a relatively small turbocharger to deliver high-rpm boost, the exhaust manifold pressure can exceed the intake manifold pressure such that the extremely high-temp exhaust gasses can be blown back into the cylinder and go BOOM!.
