The friction surface of a vented rotor consists of two metal discs held together with vanes of metal which creates tunnels that let the heat escape. We call those cooling vanes. With the solid rotor, the friction surface consists of only one metal disc. This greatly reduces its ability for cooling. It is a common misunderstanding that you can choose whether you get a solid or vented rotor, this is NOT true.
Blower surge is one of those hot-rod dynamics that presents a paradox to enthusiasts. In one ear it sounds like the engine is struggling if not defective. Then the other ear is treated to a throbbing cadence of performance pulses that help define a unique cool factor that not everyone understands. On one hand blower surge can be so smooth and melodic that itâll put a crying baby to sleep.
