5 Things You Should Never Do In A Turbocharged Vehicle

Jun 03, 2021
Hello everyone and welcome in this video we're going to talk about five

things

you

should

never

do in your

turbocharged

car and as you can see we're in my 2014 Subaru STi which has a 2.5 liter

turbocharged

engine now the first thing I do. What I want to talk about is not running your car hard until you've let everything come up to operating temperature and you know you may think the common mistake is to just look at the coolant gauge and see that it's reached operating temperature. Well, what happens is that the coolant actually rises much faster than the engine oil, usually because it has a thermostat that closes the engine block, and by closing that engine block, it can heat up the engine coolant. very quickly and regulates the temperature inside the engine block;

However, your engine oil has to circulate through the oil pan, so you have a large reserve of oil that needs to be heated and, as long as that oil is not at operating temperature, it will not flow as fast as it will do so at operating temperature, which means it will have less protection, so it is essential, especially with turbocharged engines, where you send oil through that turbocharger which will spin at an incredibly high speed. rpm, you want to make sure that there's adequate oil flow through everything to make sure that it's really protecting everything well, so you know this is going to be different for every car, but normally I would just say wait a few. extra minutes after you've seen that your engine coolant has reached operating temperature before it actually starts to hit your

vehicle

, the second thing I want to talk about is not turning off your engine immediately after you've been running your car. really. hard and then what happens in these scenarios?

When you drive your car very hard, you will have these spots like the turbocharger and other areas where you will have very hot areas, so when you turn off the engine, you will turn it off. The flow of oil is interrupted, so you will leave the oil next to these really hot areas, so what the oil that is next to these hot spots does is start to burn the lighter end of that oil, leaving a thicker layer. oil and also begins to break down, leaving a thicker oil and, if you think that that oil does not have the flow characteristics that it initially had, which are desirable, that means that you will have to change it or oil more frequently and, in addition, it will have a little more wear as a result of not having as much protection, so be sure to let the engine cool. cruise, don't go into your boost and let the engine oil temperature drop, cool down those areas that are really hot so you don't break down the oil as much as you know once you've been running hard now that the The third thing about What I want to talk about is that you

should

never

like your engine turbocharged, so what I mean by is give it a high charge at a very low engine rpm so that your engine rpm is very low, let's say you're in fifth gear. at a thousand rpm 1500 rpm and you floor it to get a lot of boost, but at very low engine rpm this is a dangerous condition, there are actually three reasons why you don't want to do this, so the first reason is essentially you are putting your car at a huge disadvantage gear wise, so you're asking for a lot of power at an engine speed where it can't make that power, so the smart thing to do is to just downshift that way you have the torque. on the wheels to compensate for it and you can produce more power and accelerate easily.

You know you can notice some vibrations,

things

like that when you're in this condition. The second thing is especially true with diesel

vehicle

s, it's in these scenarios where If you're trying to make more power, your engine may say, well, let's inject more fuel, but it can't take in more air because it's at these really low engine rpms. and as a result, you inject a ton of fuel and you're in a really sticky situation. rich mixture and this really rich mixture goes through the exhaust so you know it can burn your catalytic converter or damage your exhaust system if you know different systems of course for diesel engines but it will send all this fuel coming out the exhaust you will get low emissions, you may see some black smoke coming out of the exhaust as a result of this in these conditions where you are at a very low engine speed but you are trying high engine loads.
5 things you should never do in a turbocharged vehicle
To get a lot out of it now, the third reason why you don't want to do this and I think what people are most interested in is the fact that you can really damage your engine, so there is something called low speed pre-ignition that can happen. in these small turbocharged engines in these high load, low engine rpm conditions, so what happens is you actually have the ignition on much earlier than when the spark plug ignites it, so you advance the spark timing significantly and you're not doing this in a controlled manner and when this happens it can significantly damage your engine, it can fix the pistons, it can destroy the spark plugs, things like that, and this can't be controlled by simply advancing or retarding the timing because the timing happens later. from this.
So it's a unique condition and it seems to be more of a modern phenomenon with these little turbocharged engines when they're at high load and low engine rpm, so the reason why it occurs is a little unknown and you know, I want to make a video separate to explore some of the hypotheses that are out there as to why this happens, there are some good scientific journals you know that explain why this happens, but it's a deep topic, the point is If you are in a turbocharged car and you have low engine revs , you don't want to use high boost in these scenarios because you could run into this low speed preignition condition and significantly damage the number four engine.
You'll want to make sure you always buy the best fuel you can buy and this is especially true for modified turbocharged engines so in these scenarios you know you just want to minimize the knock you want to minimize the likelihood of blowing up your engine here we have some big obstacles in the way, so when I say you want to minimize, there are different ways to do it, you can timing, you can run a really rich air-fuel mixture, you can reduce boost. but you know that all of this will basically reduce the power to a certain point, so what you want to do is find that ideal area and allow your engine to make the most power, so the easiest way to do that is to just give yourself .
The best fuel you can get to run is 87 octane or you know the European equivalent of an average knock rating of 87 octane, so you guys use a different system, but anyway don't use the lowest gasoline out there, use the highest gasoline available. The highest octane rating you can buy and as a result of this you will minimize the risk of the engine not running and finally number five as we get into some corners here and this is just to have an excuse to talk on the slide. angles, but you don't want to bottom out when exiting a corner, especially in a turbocharged vehicle, so what if you know how to have a stable vehicle?
Well, a stable vehicle means that its front and rear tires have the same slip angle essentially the same slip angle if one of them becomes larger than the other if the front is larger than the rear it has understeer if the rear is larger than the front end has oversteer and so on a turbocharged vehicle like When exiting a corner, the way you increase essentially in all vehicles, the way you increase the slip angle of a tire is by increasing the load, so If you accelerate, brake or take a very hard curve, where are you going to do it?
It's increasing the slip angle of that tire now on a turbocharged vehicle when you come out of a corner and let's say you floor it. What happens is especially with cards that have turbo lag. You're going to be waiting and you put your foot down. and it may not come out and then all of a sudden the turbo lag is overcome, you send all that torque, let's say to the rear tires and now you've sent a significant load to those rear tires and sending that significant load to the rear tires. it greatly increases just the rear wheel slip angle and when you do that of course that means the rear tire slip angles are greater than the front and that means you're going to oversteer.
The same thing happens in a front-wheel drive vehicle, all you have to do is start. you spin the front wheels and then you start to understeer, so it's a dangerous condition with turbocharged vehicles, you have to make sure you're really progressive with your throttle modulation coming out of a corner, because if you're not and you're just on the floor, you're going to find yourself sliding, you know, in an uncontrolled manner, you know and possibly in a controlled manner into a rear wheel drive vehicle and you know what you're doing so you can certainly have some fun with that, but if you're trying to be safe or if you're trying To get the fastest lap time, you want to avoid simply hitting the ground and make sure you don't oversteer your vehicle when exiting a corner by overloading those tires.
So thank you all for watching and if you have any questions or comments, feel free to leave them below and welcome. In this video, we're going to talk about five things you should never do in a 4x4 and it's pretty cool. You'll be in a different four by four truck or SUV for each of these, so the first point I want to talk about will be on the pavement and then the rest will be off the pavement and so on for this first one. one I think most people know that if you use a locking differential for either the front or rear
