I know this has been covered before but i made a how-to while making my det can so i just thought i'd share. its permanently hosted on my website at:

The parts



<b>building the engine block side:</b>

-Take your 4-5" peice of copper and using a vice grip or other means, flatten a good 1" to 1.25" section of the pipe.

-Now take 1/8" of the tip and bend it 90*. You are trying to seal off the end of the tube. Drill a hole just large enough for the bolt in the flattened part of the pipe.

-Solder the 1/2" threaded fitting onto the end of the pipe, and also solder shut the flattened bent tip.

-Take some teflon tape and wrap the 1/4" barbed fitting and screw it into the pipe fitting.

Here is what the engine block side of the det can will look like




run your 1/2" hose through the firewall and into the cabin


Bolt the block side of the det can to the block. Connect the hose to the block fitting.


You have an option here, you can:

-T the 1/2" hose and run two lines, 1 to each side of the ear protectors.
-just run the single line to one side of the ear protectors.


I chose to just run the single hose to one side of the ear protectors for simplicity and to save money.



Drill 1/2" hole in your ear protectors


Shove 1/2" of the tubing into the ear protectors and seal it with duct tape. The tape allows you to disconnect the ear protectors and remove the det can when finished. Another option would be super glue or hot glue. this would seal better than ductape but I'll see how this setup works.


An overall shot of the setup



<b>congrats you have successfully built a det can. You can now listen to detonation to help you tune your timing on the streets</b>





enjoy,

Why didnt you run the line from the bottom of the ear muff part, instead of the side? Im using the same ear protectors form harbor frieght, how do they work?
good write up
LAST I vote for a sticky.

I used 3/8" fuel line and it didn't work for ----, I might have to get some of that type of hose. I threaded a brass fitting into the muff, would that cause a problem?

setup works great! i can clearly hear my valvetrain ticking away, thats the most consistent sound. i only took it out for just a bit and around 4.5k i heard kind of what sounded like throwing hard rice into a pan could that be detonation? haha i think it might be

i need a driver, so i can sit and listen and focus closely

im glad you guys like the writeup
