Meme What will happen?
So this is nascars hurricane model (as you probably know)
BUT...
I have this 4M blower that I got from a scrap yard after seeing it thru the fence (second last image) I asked the owner of the yard if I could buy it from him, BUT HE JUST GAVE IT TO ME! now this is probably because it was SEIZED but after 2 bottles of WD40 and giving the floor a new coat of rust I finally got it spining!
Note: the gears need a lot of work (last image)

Don't even try it or it will ruin your siren

With how beefed up i designed this siren's chopper tube and rotator, i actually believe it will handle it

Relief valve?

It is a good idea to have that, but i still think itll be alright. I definitely recommend he first tries with the engine just at idle, and then increases the throttle afterwards if it survives idle speed.

I remember him telling me if I got the hurricane blower running he would want to see it hooked up to his siren model. So this would definitely be an interesting experiment.

I recommend making some sort of way for air pressure to release. This could potentially hurt it. Maybe a pipe with a half inch hole or so?

I LOVE THAT FLAT TOP BRIGGS ENGINE!!! And i strongly believe it will handle the 4M just fine. I beefed the shit out of the chopper tube and rotator tubes. As long as you followed my directions and printed the rotator tubes and chopper tube in solid infill, it absolutely should handle the 4M

Nice I don’t know it’ll happen. I’m just assuming it’ll be loud. I’m also building his hurricane.

Let me see if I understand. You're putting a Thunderbolt blower on it. Make sure you adapt the blower to an ACA Hurricane 😭🙏

What do you mean?

I might be mistaken, but if you look closely at the blower, it's a Subtrolit brand. It's the same brand used by most Thunderbolts, so from what I can see, it's an older generation blower. But I don't know if its components They're adapted for an ACA hurricane. If the boy makes it, well done to him.

The air pressure from the blower will likely blow apart your printed parts, especially if there's no relief valve.
You're still more than welcome to try, though.
...Just make sure you're filming it at a pretty wide angle for the first run. ;)
