We all been waiting for this moment, yes 2020 & Up 6.7 Powerstoke Tuning is now here for all your 2020 & Up Superduty's. At least it's harmless to use.Product Description 2020-2021 Ford 6.7 Powerstroke Single Tune I filled up one plugged exhaust pipe with their soap mixture and left it for about 30 hours and nothing happened. I have tried some of their samples and I thought they just did not work. There are several companies that sell special soap for this. A mixture of soap that dissolves the carbon.This is not a real good option because the caustic soda is, well, caustic and dangerous to use. The mixture should be about three pounds of caustic soda mixed with one gallon of water. Simply fill the pipe with a solution of caustic soda and water. Use caustic soda to dissolve the carbon.Cut the exhaust pipe open on the back side and then burn out the carbon.Melt a few baffles out and the pipe will run very loud. There is a big risk of melting the internal baffling. This is tricky but works well if you can do it. If the carbon goes out it is quite hard to get it burning again. Sometimes you can actually see the progression of the burn, as a red hot band around the body of the muffler, as it moves from one end of the pipe to the other. Once the carbon starts to burn you must make sure enough oxygen gets blown through the pipe to keep the carbon burning until it is all burned out. You must heat the pipe hot enough to get the carbon burning but not so hot that you melt the steel of the pipe and internal pipe baffles. The problem is that you need an oxy-acetylene torch set up and considerable skill in burning it out. This the most expensive and sure fire way to cure the problem. The different baffles collect the unburned carbon and plug up but you can't easily get to them. Many stock two stroke exhausts have non removable baffles or have only one or two baffles that are removable. If the baffles are not removable it is much harder to clean them. If the exhaust has removable baffles or is fiberglass packed, you can easily clean them and replace the fiberglass packing. This is especially true of quite exhausts. The bike will start easily but just will not rev up. One problem with two stroke exhausts is that they can get plugged up with carbon from the oil used to lubricate the engine. I am assuming he would want you to see this.
I have tried to e-mail him but there was no response. I got this from a web site, made by Joseph A. That is why two strokes have such a narrow power band.Ībove is a really nice Gif animation showing how it all works. Running the engine at any RPM above or below the designed RPM and the supercharging effect will be much less effective. There is only one draw back to all this and that is that this supercharging only happens at the specific RPM that the pipe was designed for. Without that properly designed exhaust pipe called an "Expansion Chamber", the two stroke engine will have no real power. This sort of supercharges the engine, giving the high power out put of a two stroke engine. All this happens in three to four thousands of a second. Then, just before the piston closes the exhaust port, this negative wave changes to a positive wave and pushes the fresh intake fuel charge BACK into the cylinder.
This sucks the exhaust AND part of the new intake charge into the exhaust pipe. If the pipe is made just right, a wave with negative pressure reaches the exhaust port just as it is fully open. This wave pressure can be as high as seven pounds per square inch (Both positive and negative waves) and travels at 1600 to 1700 feet per second. Hit another change in diameter and the wave changes back to positive. If it is a positive wave and hits a change in diameter in the tubing of the exhaust pipe it changes to a negative wave. This wave can be either positive or negative in pressure. The exhaust gas rushes out into the header pipe and a pressure wave is created. When combustion occurs in a two stroke, the piston is pushed down by the expanding gases uncovering the exhaust port. He reportedly said "You'll know when you have the design right, because the chamber will then be impossible to fit on the motorcycle without having it drag the ground, burn the rider's leg, or force the relocation of one or more major components." ¶ Walter Kaaden, the chief engineer for MZ motorcycles in the 1950s, is generally considered the father of the modern two stroke expansion chamber.
