I have a number that has been embedded in my brain since I was 16 years old (73 now). As a coal mine apprentice electrician in England, I attended college & studied electrical, mechanical and mining sciences. I learned from Professor Hedley (mining sciences) that the perfect (and worst) possible mixture of Methane Ch4 and air underground, is 14%. Now add coal dust to the mix. Here's the number y'all can use as a reference when trying to imagine what combustion pressures are like in an engine such as the one the guys just built. And why ARP makes some of their head bolts withstand 230,000 psi of tensile stress and stretch. If & when the above mixture is ignited, it expands (explodes or rapid-burns) at the rate of four (4) miles per second. Imagine that happening in you truck engine at 6,000 times per minute. Y'all are welcome, have a nice weekend.

That crank balancer is insane. I remember watching old Mr. Paola balancing my crank many years ago, I can understand why some people think it's voodoo. I think he did it by instinct and intuition as much as by measurement. Safe to say, his machine wasn't anywhere near that fancy. But that was 30 years ago, too. And the machine was really old at that point.

[@risingwind8943]

I watched a ton of your stuff as a kid on TV. Absolutely amazing content. You guys rule.

[@jameslmorehead]

My friends and I used to build 10k RPM small block Chevy engines. Really, all the secret sauce was in the balancing. Prior to balancing, we would weigh each part of the rotating assembly, find the lowest weight, and remove material from all the others to match. This was done to an accuracy of 0.01 grams plus or minus 0.0025 grams. As we worked, everything was stored in an acetone bath so any debris or oil would automatically be removed. The acetone was blown off, and the part allowed to dry for several minutes in a box heated to 100F to keep everything at a consistent temperature while we worked. Everything was then vaccume sealed in plastic as a cylinder set. This keeps everything clean and together when sent to the balancing shop. The shop we used had an optional balancing with a much higher rotation speed. I think most shops rotate the crank around 500RPM. Our guy was able to balance at 3000 to 5000 RPM. The higher speed makes the forces greater, thus the balancing machine more sensitive. Since we used them all the time, they had balancing weights machined specifically for us. They could add washers to the weights to match the rotating mass to the tolerances in which they were matched. This was a great deal of manual labor, but for teens, it was a very lucrative operation. I think we ended up building a little over 50 engines when we were doing this. All the blocks and crankshafts were pulls from junkyard cars. We only would get 4 bolt main blocks, mostly 350s.

[@taylorsrus9543]

Yeah none of that extra was helping. The balance shop probably laughed when you left. Do you think the weights are that precise in a running engine with oil slinging around? carbon/oil deposits? You just heard an expert tell you there is no secret sauce. That is what is referred to as snake oil.

idk when you're building for boosted engines you really need to consider your clearances... if they just slapped the supercharger on it it might run excellent but someone correct me i believe its in your best interest to at minimum re-ring it and make sure the compression ratio is within range.. but someone correct me because I don't know the specs right off the top of my head.

i do find it amusing how the American engine build community is amazed how much difference proper blueprinting/balancing makes to an engine, their European counterpart have been doing this for decades creating horsepower from much smaller engines. its insane the outputs they are getting from small block V8's today from simple science and not just massive volume

I wish I could have you guys build me an engine for my 98 Sonoma. Your work is amazing... 😉👍🏼

[@Bloodcurling]

This was great. One improvement you could have made was with all the detail you went into the engine, could have explained how this twin-screw compressor is superior to the TVS roots type. It was glossed over

[@midnight347]

The twin screw isn't superior to the tvs lol. That is an old out of date way of thinking. Why do you think it takes at least 3 liters to even match what the 2650s are doing I mean if the twin screw was "more efficient" it would be the other way around. And when it comes to heat soak the tvs doesn't heat soak any more than a twin screw unless you're way overspinning it which is tough to do considering how many rpm a tvs can turn. The modern tvs are very efficient and pound for pound will make more power than a twin screw displacement for displacement the only way a twin screw can exceed a tvs performance wise is with a decent bit more displacement it certainly isn't gonna do it at the same displacement so therefor the whole more efficient crap is a bill of false goods people have been sold

[@AB-80X]

I think you're asking the wrong questions. TVS vs. Lysholm is as was said, outdated. Both are good designs and the new fifth gen Whipples have moved them up alongside the Magnuson blowers. What I suspect that you are thinking about is some of the older Eatons and the old roots X-71 series blowers. Everything has its place and use, it depends on what you want to do. If you want some explanations on what each style of supercharger can do, there are plenty of videos out there showcasing that.

@@bigboreracing356 so let’s just keep going .0075 per side on ever rebuild. No need to ever resleeve, just go til you bore into the next cylinder or water and then start over right?

With a supercharger or turbo(anything that compresses air into the cylinder) compresstion ratio is better at 7.5 or 8 to 1 because you can put higher cylinder pressur because you can make more engine power making more engine power.
