- Grab a seat and pull out your notebook because class is in session. This week Davin dives into compression ratio on our 1993 4.6L Jeep XJ engine. It's not an overly complicated process to calculate what the ratio of an engine is, but there are a few things that can trip you up. So, join us as Davin breaks down some of his tricks to make sure you've got all the numbers you need.

Thanks for the shout out to my auto shop classes Davin. We really enjoy and appreciate the correct information. You should have seen the look on their faces when you mentioned us by name. A few thought that I had somehow manipulated the video. It was a great day in the shop.
Relatively speaking, this was a relatively great compression ratio lesson. I'm relatively impressed and sure my relatives will be as well. :)
I came here for a greasy rebuild, I left with a PhD in applied Physics
I really like the shout out to the high school class. We need the fresh blood in the industry
Really happy to see you guys working on a 4.0! The Redline Rebuilds series inspired me to do my first engine build, so this past summer I built one up for my 99 cherokee sport. Love the vids and keep up the great work!
This is well beyond my comprehension. Great vid and I very much enjoyed this.
Best series on YT, hands down!
Well this is gonna be an extremely helpful video for years to come
I love that you guys cover the “thinking” side of engine builds. So many build videos are just guys spinning wrenches. But this stuff is what truly makes an expert
I'm the guy who ran the numbers in the last video. Didn't realize your pistons were dished
Really enjoying the series, and you guys always have great music to go along with your videos. Always the right vibe!
Outstanding work, sir. Thank you for breaking this down for us plebs. I've built a few engines, mixed and matched stuff; but, luckily for me all the measurements were available via a few different online compression calculators. Said calculators are very helpful, but sometimes you gotta customize a few things... I've never dared to used a buret, nor really understood how. Your demonstration clears up a lot of questions I had. Nice!
It's funny how real engine building is a process of experience, attention to detail, patience yet TV shows it as one of high-jinks, smashing stuff and throw it together.
I am loving this series. My dream garage is a Miata with an LS3 and a Cherokee (XJ) with a stroked 4.6L engine. You're literally building my dream Jeep. Some day I hope to follow every video as I build one in real life.
This project series has been absolutely great. Keep them coming!
I saw that 8.49:1 and my immediate thought was "thems turbo numbers!"
I must say that this series brings lots of useful informations. Keep them coming. :)
Wow, I've not done physics like this since uni. I hated it then, but actually enjoyed following along here. Always love these videos, with or without math!
Love the math. So key to having a successful result. Not doing it would be a disaster in the end. Well done. Love these videos. Science/Physics, it's all so important. Cheers from Toronto!
That's awesome job, professor! Thank's to share knowledge!
