Not sure if this is where it goes, but just thought I would share.

Now, I do this for friends and my self, not sure if it really does anything. On the butt Dino I feel better response and smother idle.

Here are some pics

Started by cleaning it up and bit and painting it


then wire wheeled the butterfly and sand it with 120,220,320,400,600.




Now time for the inside
I do the same sanding process, but I like to curve the edges a bit.




That's all thanks for looking, and if this is in the wrong forum please move it.

 

i doubt it really does anything, but sure does look pretty... good for shows i guess.

 

Well I was thinking it's going to make the air go through smother, kinda like when you t-body is really dirty and you clean it the car runs better.

 

Very shiny. You gain the most in throttle body flow by making the shaft and the bolt heads thinner, but normally make it to where you can't take it apart again.

It could be beneficial at wide open throttle, where the air flows over the (now polished) surface. The shaft the butterfly plate attaches to is a huge obstruction. I think if that could be relocated to the other side of the plate you would see part throttle response and power increase. I don't know if anybody has tried this but it makes sense

 

I was thinking it didn't hut it anyway to try.

 

polished surface actually creates more turbulance

 

doesn't a slightly rough surface create low pressure spots on the surface which speeds up the air moving over top of it? kinda like why you don't want to polish the intake ports on a cylinder head?

i could be totally wrong on this but i thought that is what i read.

Good article codenamezero... do you know what roughness coefficient is too smooth?

 

I wonder if anyone has every taken the time to dimple out the whole intake manifold and throttle like a golf ball

you dont polish the intake ports on a head because fuel doesnt like to atomize on a polished surface.

hehe

 

That throttle plate looks nice and shiney. Good job on that

 

put the throttle plate on a chain, wear it around your neck, and call it a day.

baulin!

 

OP,

Bring that thing and a stocker to a flowbench, see how it does.

 

I would have I had the ability to do so, because it seems anything you do to your car make it work in your head.
