I purchased a period Explosion Whistle with spark plug adapter this last weekend and I'm mounting it on my 25 T. Does anyone know of a good route for the actuating cord or cable. I don't want to drill any "non factory" holes in the firewall. Back in the day were these operated via, cord, small cable or chain? I suspect a non conductive cord would be the way to go. Any suggestions?
I had one which I took off my car because I don't think it's good for the engine. maybe when idling or going slow in a parade, but it makes the engine miss on one cylinder whenever you operate the whistle. the way it was installed on my 22 was on #2 spark plug. there was a pulley on the rod between the radiator and the firewall right over the spark plug. The cord then went up the steering column through the hole where the steering column goes through the firewall. right alongside the horn wire tube and then tied to the steering column under the gas and spark levers. To operate you just pulled on the cord.
I've seen folks use a stiff wire coming through the firewall at an angle so they don't have to reach so far to pull it.
With a cord or a braided wire, I think you would anchor the non-whistle end of the string to the steering column or, with your 1925 T, to the instrument panel. Otherwise, if you put some sort of pull on it you would have to grab it down by the firewall.
I sold an NOS whistle a while ago that had a cord in the box.
Here's another one that I sold - my dad picked it up at least 65 years ago but never put it on a car - it had a cord on it:
Just don't let the wire touch a spark plug. How do I know this??????? Les
That's an unusual version I've not seen before, I wonder how well it works.
So, use a cord not a wire, ac'cord'ing to Whistler, but not According to Hoyle?
Puns Untie! er, ah, um. . .
They sound like a chirping bird at speed, heres one being tested with air, but the T blows pulses of air through while running , making the chirp chirp sound.
The example I picked up at the swap meet for $40.00 happens to be the twin to the one in the second photo. I just wanted to install it as a conversation piece for the most part. I really don't plan on using it much.
Installation of one of these Explosion Whistles is also begging for membership in the Two Piece Crankshaft Club. Ask me how I know! It was on the Glidden Tour in Colorado Springs in 1976. I had just installed one on my '23 Ford touring. It kind of chortles going downhill - or 'down mountain' in this case and you heard the explosion whistle for miles when climbing. But, like Norman says, the loud "Hey Look At Me" explosion steals the power of that cylinder when actuated and, in my case, broke my crankshaft. I was young then so replaced the crank overnight with the help of Les Donnely in Pueblo, CO and threw that damn explosion whistle off the worlds highest suspension bridge over the Arkansas River.
George, thanks for the warning. Like I said I don't plan on using it often, and when I do it will be for just for a second or two. I mostly installing it as a conversation piece.
Anyone else have one of an explosion whistle cause a crankshaft to fail?
How do you know that was what broke the crankshaft? Did you eat a tomato that day, maybe that was the cause of the broken crank? Is not anecdotal evidence great? The crank withstands 4 major explosions every 720 degrees of rotation and does not break every day.
I remember when a extension was put on a spark plug when that cylinder fouled the spark plug, but it robed power on that cylinder, why wouldn't the explosion whistle do the same.

You you don't have to put it on No 1, 2 or 3 will work, 4 is a bit tight. When I had mine I only put it on when I was going to be in a parade. RE extension, guess it depends on how long the extension was but yes it might rob a little power.
For those who may not be aware, there are three methods in which an explosion whistle may be installed:
1) in the spark plug hole using a spark plug adapter
2) if the motor was originally equipped with priming cups, the whistle may be installed in lieu of a priming cup. This may also involve an adapter if the whistle threads do not match the priming cup threads
3) tapping into the combustion chamber and screwing the whistle directly into the head of the motor.
Howdy Jim Rose,
How do I know the explosion whistle was the cause of my broken crankshaft? And I don't quite get the 'tomato' analogy. I had driven that touring thousands of reasonable and trouble free miles prior to the '76 Glidden Tour. Then I installed that $@/? explosion whistle the day after the Pikes Peak climb and my crankshaft broke with the whistle engaged and gaining elevation. So that's my cause and effect story and I'm stickin to it.....
