This just keeps getting better and better

Thank man

Hi haha! This week I have more update.
I just got the 2.5" aluminum pipe so let make a air horn for my throttle.
Just do it by simple, flare and cut, that's it!

It just raw but I love it, next week will completeit 8 pcs.
Enjoy

Finally I finished 8 pcs. throttle air horn for my 3uz itb.

[phet_fresh]

Hello!
What is your opinion? I love it. still think about the finish to be brushed or polish.

Something big is going on here, can't wait to see more

Thank man! Will keep to update

What did you use to flare the ends? looks great

[cossie]

Im no expert, but shouldnt all the velocity stacks be equal length?

Cool project!

^this

But it looks good though

There is so much amazing fab work going into this. Wow, kudos man.

You could lathe the mold and press by hydraulic.
This my mold, it standard tool for exhaust pipe.

Thank guys, I'm no professional too. I just think the important part for velocity long equal should be after valve. These air horn I attempt to complete decollate the ITB more than performance function. BTW, respect your!

Oh the stack issue!!!!
many opinions but the better is equal stack, about the resonance, pressure etc...
Thank you again...
Btw, I will keep kool first the healthy engine later

[cossie]

Yep.

I had a conversation about velocity stacks with a friend who has a degree on engines.
He said that with part throttle the resonances come from throttle flaps. But on full throttle its the velocity stack ends that create the resonance.

Also you can use different length stacks to better the power curve wider area than equal length stacks. Then the stack lengths have to be paired with cyliders on same con rod journal (same phase).
