Right on, exactly what I want to hear 👍

⁠@@ReignitedAutoThis video did help a little, although I use a slightly different calculation based on my measurements of my own cars engine. Hight x Width x Hight divide buy 14. 225 Cm X 64 Cm X 58.38 Cm Divided by 14 Cm remember I have to scale down 14 Feet by 30.48 Cm, it = 60L a true monster of an VR8 engine.

@mobythemerpup1515 I had one of those, they're pretty quick! 😄

Man my 4th grade teacher told me they found displacement by dropping the engine in water, starting it and measuring how much water was displaced, you said it’s air, how common is this water method or liquid method used ?

Fr i was a fake car guy before i watched, now I'm an educated fake car guy​@@ReignitedAuto

Appreciate you watching!

Good idea 👍

Just doesn't have the same ring to it 😂

I have two topics. You should come Camshafts lift and duration. I feel that one is harder to understand especially on how it affects the powerband. Secondly, you did a good job on Displacement. I think you can take a step further on the difference between long and short strokes.

Coolant system like how does the heater core and engine use the antifreeze to cool the engine and ac

Swept volume vs. total volume, and how different cylinder heads can affect not only total volume, but also compression ratios.

Thanks for watching!

Love hearing this, thank you 👍

Glad it was helpful!

Glad it helped!

Appreciate you watching! 👍

Thank you for the kind words!

Glad it helped! 👍

No, 5.7 is the way to go when boosting, 392s are decent anything up like the 6.4 will blow the fuck up

That's actually a tough question. For my own builds I'm completely fine with reusing the timing chain because we really don't see many if any timing chain failures. However, if I'm recommending to a customer I'll probably say to replace it just to be safe.

@@ReignitedAuto thank you for taking the time to respond I really appreciate that. The reason I ask is I replaced the cam in my charger rt and the timing came of. Didn't do to much damage just chipped one of my pistons and bent a valve on the same side but the other side looks fine. I haven't taken the valve cover off to see what may have caused the chain to come off yet but I didn't want the same problem to happen on my jeep. I may have tighten something down to hard or didn't tighten it good enough on the cam tensioner or maybe the timing was off. It was my first time doing it. Thank you and keep making videos man I love the knowledge you give very helpful 👍👍

No, there is an air to fuel ratio that takes place inside the engine. This ratio changes constantly as the engine is running, but the "ideal" air to fuel ratio is 14.7 parts air to 1 part fuel. 👍

Depends on a number of factors. I actually like a small displacement turbo engine, but it needs to be in a light vehicle to make sense.

That's actually a great question, and one that has a very long answer 😄. The simplest way to look at is is that your engine is an air pump, the more air it can get in/out, the more power it makes. This is why an intake helps, because it helps the air to get in, this is why a larger exhaust helps, because it moves more air out. Cams accomplish both. Usually all of these things working together is what gives the best results. For my part, I think bolt ons like that are sort of a waste of time/money. I like to go straight to forced induction supercharger/turbo because you get more power for your money. 👍

@@ReignitedAutoawesome! And I'm assuming that the lesser the time between piston cycles the more performant your engine becomes in turn, such that wider pistons and smaller rods are "better" for overall performance. Is there anywhere else where I can get more information on the subject of engine design? (I'm taking on a very long-term project for fun and I figured I'd start with the engine).

I'm glad I was able to help! 👍

That was great! Now it is actually meaningful when I see an old Mini Cooper can be like 0.8 liter, a Bugatti v16 that can be 8 liter, my Scion xB coming in at a whopping 2.4 liter, compared to my old Dodge Ram van that was a 5.2 liter... water bottles will never look the same again! Thank you my excellent sir!

You can't really think of it that way because the pistons are at a different point in their stroke in relation to each other. Just think of it that it's a full 5.7l after all 8 pistons have gone through their cycle.

That is the challenge! In my case I like to jump in with both feet and see how much needs to be cut out 😄. It's the best way to learn in my opinion, just do the best you can with what you've got and your skills will grow every new project you work on. 👍

I like it, a new system of measurement. Like horsepower, but better 😄👍

@@ReignitedAuto I think the flat plane crank produce more of that bang using the same overall displacement. Idk lol

It has everything to do with the efficiency of the engine design. Just because an engine is capable of moving a certain amount of air every cycle doesn't mean it does so. Some designs are inherently more efficient than others. Additionally that's why forced induction engines can make so much power, they are forcing more than 100% efficiency through the engine. 👍

That's exactly right, the 5L engine has 3.3 times the displacement of the 1.5L engine so you are going to be using 3.3 times the amount of fuel during normal operation. Now one thing to understand is that it's not really a direct correlation between engine size and the amount of fuel that is used because engine design differs greatly which effects engine efficiency. Usually smaller displacement engines are more focused on good fuel economy with lower power numbers, whereas large displacement engines are more focused on power rather than fuel economy. 👍

@@ReignitedAuto thank you!!!

They are actually the same motor. In the trucks they call it 6.4 cause its a fairly good sized number in liters but they call 392 in the car because it has a more appealing sound to the "name" and in cubic inches it is bigger than a few sports cars. It is actually a bigger displacement than the hellcat motor

@Keaton Moore - nailed it 👍

@@keatonmoore7934 and keep in mind a 392 means 392 cubic inches. They don't go by cubic inches in Canada and many other places, so they go by 6.4L. It's the same thing, just one in metric and one in imperial/standard. That's why you'll see Scat Packs in Canada sold with the 6.4L rumble bee instead of the 392 rumble bee.

@@keatonmoore7934 thank you, figured something along those lines.

In addition, 392 has a history at Chrysler/Dodge as it was the largest of the early (1st Gen 1957-58) Hemi's available.

😄 I haven't gotten that one yet, looked him up, ya I can see it lol.

Because on this particular engine there are 8 cylinders total. Whatever engine you are calculating for you multiply the single cylinder volume by the amount of cylinders there are to get the total volume. 👍

No worries, and you're right it completely depends on how many cylinders the engine has overall. In this case, the Hemi is an eight cylinder engine so times the volume of one cylinder by 8 to get the overall volume.

I knew someone would have a problem with that, what I meant but failed to specify, is that the External dimensions of an engine have nothing to do with its displacement. Much like a 5.0l coyote engine is physically larger than a 426ci LS engine even though it has less displacement. Hope that makes sense.

We have a passion for confusing everyone 😄

Unfortunately yes, I have a terrible syndrome where I look like a 40 year old man, but I speak like my actual age. It's quite debilitating.
