Two questions and aspects are, recirculation vs venting. Do you see any situation where recirculating hot air to the airbox, open to the ram air tube and before the supercharger, offers more power than venting the hot air?
The other would be whether pressure is blown off sooner.
When talking about available power, don't we generally mean at full throttle, or if restricted, at as much as the butterflies open?
In this situation, how would the differing blowoff valve reduce power? Closed either way.
Is it possible that if with throttles closed or nearly closed OEM isn't blowing off pressure at some point that aftermarket is blowing off pressure, then OEM might give more sudden part-throttle response, to an extent a naturally aspirated superbike wouldn't, while aftermarket would have only atmospheric at the throttle bodies and have more typical throttle response? Makes sense, but a question maybe as to whether that's helpful, and also any such difference in throttle response seems a different question than reducing hp as claimed.
