Don't forget about the boner.....

This is my second exhaust valve build. Its meant to improve low rpm power with an expansion chamber that is set up for higher rpm performance. It will add to overall pipe volume with a simple 1/4 turn of barrel/spool valve.

Re: Don't forget about the boner.....

This goes between the cylinder and pipe? Is air chamber getting bolted on the square outlet side?

Re: Don't forget about the boner.....

That's correct. The plan is to insert different lengths of 2 1/2 inch pipe between the two plates seen in the first photo in order to tune it in.

Re: Don't forget about the boner.....

Seems I've seen this 'idea' somewhere before . Maybe Jbot ???

Re: Don't forget about the boner.....

It looks like u damn near built a power valve.

Hack out some slides like this,

Spring and cable like a carb, jam it in that wallered out hole and stuff.

Re: Don't forget about the boner.....

Who said power valve gotta be ah slide to be considered a "POWER VAVLE"......, the "boner" I was so fond of was only missing a reasonable valve ..., i Donna dreamt slide valve ...., it ain't reasonable in the , buy it, and bolt it together world I'm in , it ain't gonna happen without too much fanfare for me.... The slide is a great style valve though....! Oh, by the way...., by all reasonable definition, this is a power valve.

Re: Don't forget about the boner.....

Screwed that one up..., it isn't no power valve. Go ahead ,now there's a reason ta shoot me....

One boner at a time.

Re: Don't forget about the boner.....

I suppose if I had been nay-kee wearing raeh-za sharp cuttings, you'd grasp upon something else to gripe about? Did you see the first cutting tool. Any how, I post and some bitch.

I am not crazy. Everyone else is. Can't you see?

Re: Don't forget about the boner.....

Here is the first valve build. It was cast in aluminum. It worked really well but the spool was crappy and the whole thing could have been smaller and weighed less. It looked cool though considering it hugged the cylinder.

Now I'm just curious about this what is the purpose of adjusting the flow? Is it about restriction because you could just make a stack and have a weighted lid or an adjustable tension spring what is the real purpose I mean? Can you automatically adjust the shape of the chambers of the sound wave is bouncing a certain way back up the cylinder are you creating some kind of vortex I mean if it's not restricted and you have reeds you just have to have the right shape chamber to have good low-end and then the high end is just a matter of no restriction and the shape of the chamber to start with I got an 80cc aircraft exhaust no restriction it just had some straight pipes in the way of the sound waves it was quiet and it ripped
