Thunderbolt Blowers?

:TBolt: I am a little confused with the thunderbolt blower types.
All I know (and may not be correct) Is that the A1 blower is the quietest and has the 'Pulsey' sort of sound. I am not certain of any others? Could someone explain and possible find videos of sirens with different blowers so I can try and find a difference with hearing. Thanks! Tom :TBolt:

I'd like to add though that the "loud" portion of said blowers affects the single and dual tone heads differently. For example, the 6M due to its slow running gave it a smooth distorted sound. A dual tone 6M might appear a little quieter than the 5 and 4Ms. The 5M gives the dual tone head a very loud buzz and seems a quite a bit louder than the 4 and 6M (but also consider it has twice the airflow as well. 320 CFM I think? My thunderbolt ran off one.) The 4M is the most common. Now on single tone heads the bigger blower doesn't seem to affect the sound as much when we talk about 4 and 5M blowers. It may or may not have been louder but honestly it's sort of hard to tell. The 6M however because of the pulsate (and because the original single tone bolt was designed around the 6M) seems like it is definatly louder than the other 2... not by a whole lot but yea it does seem a bit louder. But if you can, listen for yourselves!

Yea maybe. I know that my baby ran off a 5M or I'm pretty sure anyway given the date and the blower case.

Sorry for a bit of a bump but if you want to be able to tell just the blower apart by sound then the 6M blower makes a pulsating noise, the 5M makes kind of a humming sound with a hissing undertone and the 4M makes a LOUD humming sound.

Has anyone installed a smaller pulley on the 5m or 6M?

Greenfield it depends on single or dual tone. But yes usually 6M blowers have a pulsating sound.
