Do you know why ram tube are used? Are you naïve to its end formation? Well, ram tube in the intake manifold promotes performance at certain engine speeds by 'ramming' air into the cylinders. In the entire process the part that is extremely vital is the end formation of the tube. The end finishing is done to give a shape to the tube. The entire process has a number of variations like ram forming, flaring, expanding, reducing, IO sizing, and even beading. Even before we discuss the other aspects, let us first understand the process of ram forming.
What is the process of Ram Forming?
The one side of the tube is placed with clamps, while the ram forming tool is put into effect to structure the other side of the Ram tube. The idea is to form the perfect tube; the tool is used to compress the stationary tube down towards the clamp dies to form the end. This technique of ram forming is used in both non-symmetrical and symmetrical shapes. Ram forming also moves the material being formed a greater distance and reduces splitting compared to segment sizing tools. You need to use such ram tubes with the ram forming tools, and you can use them for clam dies formation.
Today, 150 Multi Strike Ram former is specially used to form a tough ram formation. A four post design delivers rock solid clamping, distributing the clamping force more evenly which eliminates part slippage during the forming process.

The Importance of Ram Tube Length:
The change in the length of the Ram Tube has a tremendous effect on the engine that makes the power suitable for a particular combination. The basic fact being the shorter the ram tube, it will offer more high end power at the expense of low speed torque, while a taller ram tube will increase low speed torque while losing some top end power.
Racing Applications: Shorter ram tube is used to boost the power band to a greater RPM, and you can find such tubes in light–weight racing cars. Longer ram tube is used for heavier applications or other racing venues. It enables to meet a balance of power throughout the functional range.
Perfect Ram Tube Height: If you are wondering what is the ideal height of the tube? Well, there is no straightforward answer to it. The two commonly tools used to determine the height of tube is computer models available along with dyno testing. Another technique widely used is track testing to get the right pick for the tube height.
Street Applications: A ram tube is primarily at the focal point to function effectively. It is placed in the external hood, or under the confines of a stock hood. Checking the engine combination is important to strike the perfect height of the tube. The torque generation of an IR manifold is so much better than that of a common plenum manifold, which for most street applications ram tube height has little bearing on performance.
Ram Tube Bell: In the Indy car engine, the entrance speed at the bell of the ram tube works efficiently. However, the speed depends on the premium quality designed bell. The bell provides the proper transition of the air into the ram tube which is an important process for the high air speeds generated by an IR manifold.
In this article, we have included the important pointers about ram tube that is essential for you to know. The intake runner length is important to determine the efficiency of the engine.
