We made a video titled: “10 CHEAP Tricks! to boost your car’s engine.” It was about tricks that almost anyone can use to “scratch” a few extra horses. This video is more ambitious, we have our “Hermetic Whiteboard”, because we are going to tell you how an engineer or a tuner gets more power from an engine… #cars #automobile #mechanics Become a member of this channel to enjoy the benefits: / hermetic garage A very powerful engine, but then it will pollute a lot, waste fuel and probably not be reliable. Or you can make a very reliable engine, but then don’t insist on it being cheap, because a lean mixture raises the operating temperature inside an engine, or on it being powerful. And if you want it to consume very little, don’t ask for it to be powerful. To get more power from an engine there are only two options: Make the explosions stronger, that is, put more fuel inside the engine; or second option, that there are more explosions in the same unit of time, that is, gain in revolutions. In addition, they are compatible. To gain power there is no other way… what there are are many ways to achieve one of those things, or both at the same time… Today we focus on mechanics, we will not talk about electronics or the famous reprogramming that, especially in turbo engines, can allow you to gain power without much cost, yes, at the cost of losing, as we have explained to you on the hermetic board, in other sections. We are not going to talk about it because the best ones are not spectacular, not as much as in a new or completely prepared engine, and because we already made a video titled “Repro of the control unit, is it interesting or not?”, which you have at your disposal. More is… more. An infallible formula to increase power is to increase the displacement. All things being equal, more displacement equals more power. And also “quality” power. I have written many times that “There is no better quality power than that obtained by increasing the displacement”. Pressurized air! The more air you “put” in the engine, the more gasoline you can put in and the more power you will have. If an engine does not have a turbo, to increase power it is a good way and if it already has one, to put a bigger one or more than one, too. Cold, better. With equal volume of air, the colder it is, the more air enters and therefore more oxygen, which is what we are interested in. When passing through the turbo, the air heats up… so one way to get more oxygen into the engine is to put a radiator in the way, the famous “intercooler”. Lots of gasoline. Although cars with carburettors have not been manufactured for a long time, there are still classics, so let’s talk about them… To put more gasoline, the more carburettors the better. That is why engines were prepared by putting double-body carburettors, almost equivalent to two carburettors, or by putting more than one. Now all this is achieved by means of electronics. Direct route… Let’s talk about intake manifolds, the ducts that carry the air or the mixture. These ducts must be of equal length and sometimes they are interconnected to take advantage of the “vacuum” left by a cylinder to feed others… it’s like a musical instrument. Bigger “holes”… … or more holes. I’m referring to the valves. The normal is 4 per cylinder, there were motorcycles and cars, especially Yamaha, with 5 and Honda on a very special motorcycle dared to put… eight! Engines have camshafts, which are responsible for opening and closing the valves. In addition to having more or larger holes, raising the valves more, which is called lift, or having them open for longer, also allows you to “put” more gases into the engine. More pressure = More force. Just like the displacement, this is a rule: The more you compress the gases inside the engine, the stronger the explosion. I want to be free! The easier and faster the gases are to escape, the better. This is the responsibility of the exhaust manifold and the exhaust pipe itself. Slimming. In order for the engine to turn faster and, above all, to rev faster, one formula is to lighten everything that moves: crankshaft, connecting rods, cylinders, and flywheel, above all. Special care. If an engine burns more gasoline and turns faster, it is clear that it produces more heat and that it demands more from the lubrication system. Therefore, these more powerful engines require larger radiators, higher-performance water and oil pumps and even oil radiators. Car of the day. Since we talked about it in the video, the Seat 124 Sport… what I don't know is whether to stay with the 1,600, which for me is more beautiful, or with the 1,800, less problematic… You can see both, front and back, with a purer grille on the 1,600 and with a horn on the edge of the trunk that the 1,800 does not have, more square. Which one would you choose?
