Just going into the port or bowl area and hogging out metal does not necessarily increase airflow or horsepower. Afterwards the computer will make changes to find what is optimal for a certain RPM range. Then using sophisticated software, it will create a simulation of the airflow in both dry and wet scenarios. If you have mega-deep pockets, you can even map the ports on your block and have them digitized. With regard to porting, if you want to do porting, you need to buy/build a flow bench which is basically a manometer that tests resistance of flowing air. Matter of fact, most content you watch on YouTube relating to a Model-A is generally not very accurate anyway, so that is probably not the best source of information. The science of this is much greater than what most people can show on YouTube. Includes easy to understand, step-by-step diagrams/instructions.īatteries: Requires 2 x “AA” Batteries (not included).Is there a guide or YouTube video or something to show where and how much porting is done? I have wanted to do some porting but don't know how.Illuminated spark plugs lifts the level of understanding.Discover how an engine works with the help of digital and interactive augment reality.Construct a fully working model of an inline 4-cylinder car engine.The kit contains over 100 parts and all the tools you’ll need including the famous Haynes Manual that provides clear step-by-step instructions for ages 10 years and over. Please note: To keep things simple, the following components which are fitted to a full-size engine don’t appear on the model: oil filter, cooling system, air filter, connecting rod bearings, piston rings, oil pump, alternator and starter.Īlso, the following components are included on the model, but don’t function as they would on a full-size engine: water pump, throttle body, dipstick (without oil), flywheel and clutch.
The clear, see-thru cylinder block, cylinder head and sump pan allow you to see how every part (pistons, camshaft, valves etc.) contribute in making a four-stroke engine work. See lights inside each cylinder flash on and off at precisely the moment a spark plug would. Build a greatly simplified version of a real car engine with this 100+ piece, all-inclusive kit by Haynes® that designed to be both fun and educational.įlick the switch and see – visually – the internal mechanics of a piston engine that’s carried people around the world for decades.
