I know what you're thinking no this is not one of those viral slime videos you're looking at a process called extrude honing but what exactly is it extrude holding is a hydraulically forced abrasive flow machining causes that's carry Kubo he's a research and development specialist for a company called extrude hone AFM and to put his definition in simple terms extrude honing forces abrasive materials through metal passages via hydraulic pressure depending on the item this could have a multitude of benefits but for now let's focus on how it can make your car faster this is how putty can increase your horsepower to really understand the benefits for your car you'll need to understand the importance of airflow to an engine so we spoke with Edward Wang he's been an automotive technician for over 15 years you need three basic things in order to have a ignition event so that's gonna be their fuel and spark or some sort something to create an ignition air from the atmosphere enters into the engine bay through some sort of ducting initially hitting the intake air filter through intake tubing past the throttle body into the intake manifold where the air is evenly distributed to each individual cylinder into the combustion chamber past the intake valves if we increase the air flow to the engine the engines computer system will then match that amount of air with the proper amount of fuel if we increase fuel we can increase power and we all know what happens more power so how does this putty increase air flow well the answer is literally in the putty the putty is made out of a proprietary silicon polymer and it contains specialized silicon carbide particles and as the process of flowing goes through a part it's a quality defect so a silicon polymer the putty carries an abrasive material the silicon carbide particles but let's make this simple and see how the process works on an intake manifold the intake manifold is responsible for evenly distributing the air into each cylinder of an engine as the particles are pushed through the intake manifold via hydraulic pressure they begin sanding or grinding away at build up in smoothing imperfections this is what increases airflow and turns your car into a certified speed demon but not every time what will the results will vary depending on the part if you're starting from scratch say like a rough unshaped poured ahead having the the results improvements can be drastic but depending on how much power you're adding to your vehicle increase in the airflow may not be enough so when we talk about air flow we have to talk about balance the exhaust has to be considered as well it's the engine in in its basic form as an air pump so we have a increased volume of air coming in we have to be able to reject the spent gases out so if we have a very large intake but a smaller exhaust the diameter for instance they can actually choke the engine so if you noticed your car losing power over time you may not need that new fancy turbo to reclaim your precious speed you may just need to clean out some key parts that help air flow to the engine
