Noise generator plug material?

[jm1681]

So a friend at work offered to spin me a noise generator plug, but we only have two types of material that seem viable.

Aluminum of questionable grade/durability, and white plastic of questionable grade/durability :/

I'm not so much worried about them crushing or breaking, but of possible melting, and in the case of the aluminum, just plain frailty. We make woodworking tools out of the aluminum we use, but it's still very soft stuff. If you slide it along a sheet of paper, it leaves all manner of marks, and even wiping it down with a paper towel will turn the towel black.

The plastic seems pretty soft, but again, it goes into woodworking machine parts. I worry about melting, but I can only imagine in application, it gets pretty hot. How hot do you think that plug will get under there?

I guess the question is, if you had access to the facilities and materials I do, would you feel safe making plugs with those materials?

Both will work fine; and the aluminum is far from frail - especially in comparison to the mentioned plastic.

Think of all the other plastic under the hood. The part itself which you are plugging is made of plastic.

You will have no melting or frailty issues.

Duh, that's a really good point XD

I just figured with all the different grades of things out there, better safe then sorry

[CBR600RR]

Always better safe then sorry :-) In this case you are safe to use those materials.

Just got confirmation, the plastic is Delrin. Basically, the same stuff they make guitar picks out of It's hard to describe the stuff, but if you saw it, you'd probably understand my apprehension It looks like a candle in it's raw state; very waxy.

Regardless, it'll take less than a minute to spin, and probably about the same time to install. If I don't like it, or don't feel it is safe, it was virtually NO investment on my end

On the flipside, if I DO like it, but still feel a bit sketchy about it, it was STILL no investment, and I'll just get the Zeta hose that deletes it completely

Mine is a piece of wood wrapped in electrical tape.

Alright then XD

Any aluiminum should be fine. Not all plastics are okay for use in an engine bay. Some thermo plastics have very low melting points, and even lower "glass transition points" where they will become soft and deformable.

Most plastics should be fine but plastic is cheap why risk it. My personal recommendation is Delrin. Great thermal properties, and super easy to machine.

I plugged mine with a bolt that fit

Exactly what I was worried about

I BELIEVE that is what we have here The slug we have of it feels a bit waxy, and it FEELS like it would be easily deformable, but we DO make high-speed rollers out of the stuff. It can't be THAT soft, right?

Really, if I find that I'm happy with the delete, I'll just get an intake that deletes it altogether. If anything, this is more of a temporary "see-if-I-like-it" sort of thing

Edit: Oh, BTW Neutron, I'll be using the dimensions you specified in your thread to make my plug

Derlin is what they use on motorcycle frame sliders.

I have crashed my bike at the track at 70+ MPH and the frame slider holds up very well to pavement abraision (why it is used)

it is vary heat resistant.

Sweet ^_^

Hoping to have it made today, and on the car tonight. Oh, any chance anybody knows the size of the opening for the intake resonator beneath the elbow? Might as well eliminate both while we have the lathe setup XD

I have a 3/4 pvc cap glued into a larger 1 inch coupler then painted black. It looks fine, cost under $1, and has lasted with no problems for 7000 miles.
