Makes since to control the output of it, yet I wonder how far away it is from the memorial.DJ2226 wrote:It sounds like it has 7 or 8 ports. It sure has a mighty quick linear wind up for a 220 HP engine driven siren. That has me wondering if they are using the engine to drive a generator and blower. The generator powers a motor that drives the chopper. If that's the case then they could control the output of the siren, which could explain why it sounds so muffled. It could be that they are driving the blower at half speed so they don't blow people's ears to hell and back given that this thing has the potential of a T-135.

Probably; it could be powered by the accelerator in the cab, though.ArrowShooter1003 wrote:Is there a way to adjust the blower so that it will run at full power?
