Fancy fact no one asked for: EMD experience the need to turbo their two stroke diesels, but since this system already need a supercharger to run they came out with a clever solution. They instaled a turbo and conected It to the crankshaft with a hydraulic system, so at lower rpms the crankshaft make the turbo to spin (like a centrifugal supercharger) and at higher rpms disconected the hidroclutch to let the turbo build boost. And walah, you have a turbo and a supercharger in less space required and using less plumbing needed
Hydraulic or fluid clutch systems on superchargers go back to the 1930s with the DB-601 aero engines. Along with two stage systems. Two stage/two speed systems.
Love your channel and content brother. You explain these things perfectly, other people use all these technical terms and almost seemingly try to make it sound complicated where as you simplify it, and I am sure that is one of the main reasons your fans support your channel.

I still have mine although not registered since midway through covid due to the in-tank part of the fuel system "letting go" (its an old car that didn't like ethanol in the fuel system...I dropped off in maintenance so largely my fault). It really is a cool car and engine. I put a twin screw in mine and an old stand-alone fuel management system, SDS, to address IMHO the two biggest shortcomings of the engine and it really made it a beefier more reliable and consistent version of a G60 corrado. While the twin screw builds boost differently and was super loud before doing some intake work, it still largely feels like a g60. I kept the throttle body and boost return setup so it still has the two throttle plates and spring rates. I can still cruise around with my foot resting against the heavier spring of the bigger throttle plate and boost return valve, it still feels like a G60...nice, easy, quiet and just a light press away from that second plate and the boost and noise! I will put a vacuum actuated diverter valve at some point but I really want to keep that main "two stage" feel to the pedal if you know what I mean.
Awesome video. I like to think I know a lot about engines, but you always explain things in a more in depth way. Your channel is exciting and you have such awesome sounds! From the engines and the whole machine. Never stop.
Cool induction setups. Mazda made a Miller cycle engine that was sold in the US. Came in the Millenia. Used a Supercharger and held intake valves open longer.
Happy to finally see a face to the videos u know I’ve been around since you had like 1000 subs or so hahaha you have come a long way hope you finally have your dream car
Another fantastically interesting video!Always find this channel so intriguing! Keep up the good work my friend!! Would love to start seeing the peak torque rpm back in the specs screen! Just my two cents good sir!
Neat. (I think some of the more ancient types like the sliding-vane-type and reciprocating cylinder types deserved an honorable mention). I never knew anyone used a scroll pump on a car, and that "comprex" blew my mind. Cool.
What about the scania turbocompound truck engine where an exhaust turbine produces power which is geared to the crankshaft, rather the compressing air for the cylinders?
Hey Visioracer!! Love ur videos , I’m just curious at 4:34 while talking about the Audi sq7’s turbo/electric supercharger system, why did u show a Porsche clip ?? Are they also using this system in one of their cars?? Cheers buddy
Bráško, úprimne hovorím že si najlepší slovenský youtuber, ktorého poznám. Tvoje videá sú na tej istej úrovni ako anglické alebo americké kanály, pravdepodobne aj lepšie. Som tu skoro od začiatku a cením, že aj naša automobilová komunita má takého producenta, ako si ty. Rešpekt a len tak ďalej, podľa mňa čoskoro budeš mať aj milión odberateľov, držím ti palce :D
Wow, I actually learned something today, I never knew about vw's supercharger, I have always been into cars, and how things work, I rembered seeing that type supercharger, but never realized exactly what it was, never gave it any attention!
Visioracer If you ever want footage or content on the Twincharged Volvo T6 engines I got you covered as we have a 2016 T6 xc90 and she rips. If you want any footage feel free ask
More widely known in the us for twin-charging is Detroit Diesel with their 53, 71, 92 and 148 lines of 1, 2,, 3, 4, 6, 8, 12 cylinder two stroke diesels
Can someone explain what is happening with the inter cooler pipes @1:28 as it looks like a boost pipe is going through the rocker cover exiting straight to atmosphere.
Every Detroit diesel 2stroke is supercharged. Won't run without it. Also, the largest diesel engines in the world are supercharged. They call it forced scavenging rather than forced induction, but it's the same thing.
Many times I have heard of the G-Lader supercharger and it's spiral characteristics. This is the first video where anyone, including you, have shown how it works. So fascinating. That Comprex, though. Using the supercharger to compress the intake air AND expel the exhaust gases? That's some scavenging there.
The comprex is driven from the crankshaft, but does not need power to compress air, it uses kinetic energy from the exhaust gasses to compressfresh air. It does not help the engine scavange, it does even build some backpressure but less than a turbo. It just captures high pressure exhaust pulses in a cell, releases them into the exhaust, opens the fresh air side, using the kinetic energy of the moving exhaust gas to quickly pull in fresh air and Closes the exhaust side, so the fresh air doesn't move out into the exhaust At this point the intake air is still quickly moving in into the chamber which is building pressure, when the air stops moving the gate is shut and the pressurized air is given into the intake.
@@laurean5998, so it's more like a turbo, but it's connected to the... The explanation is kinda hard for me to grasp. I mean, this is the first time I've seen such a supercharger. Is there any video that can give a clear explanation to how does it really work?
I wonder why the motor/generator system used on F1 cars isn’t applied to road cars. This is a system that uses a motor/generator connected mechanically to the rotor shaft. When there is excessive exhaust, the mg charges a battery, and when at low rpm the mg drives the rotors to maintain boast. This gives very low turbo lag, while minimizing use of the wastegate.
Finnish Valmet tractor brand used Comprex on its model 1203 Comprex tractor in 1980s. This tractor was the most powerful Valmet tractor from its era. A 6.3 liter diesel inline 4 with Comprex and over 200 horsepower.
I forgot that VW did a scroll supercharger. My work sells an oil injected scroll air compressor 4.5kW up to 22kW, they're very robust and reliable - we very seldom have problems with them. Oil free type are the most common in the scroll air compressors, they use a Teflon seal, mostly used in the medical field, but they aren't usually above 7.5kW, also very expensive.
Seeing as electric superchargers and mild hybrids are becoming more and more of a thing, I look forward to the day when instead of having to do some arcane plumbing to install a turbo, all you have to do is buy an electric supercharger and intercooler (no exhaust plumbing needed), hook it up to the 48-volt hybrid system, and tune it to respond with boost pressure according to throttle output. Zero-lag turbo upgrades galore for NA mild hybrids. Edit: twin-charging also has an additional disadvantage compared to pure turbocharging. Making a lot of boost out of a supercharger is very difficult, especially in a system that is bypassed at high RPM. Engaging and disengaging a high boost supercharger repeatedly puts a lot of stress on both it and the engine, which means the supercharger in a twincharged engine is usually much lower boost than the turbo, leading to an engine that doesn't make as much low-end torque as a twin-turbo, small turbo, or VGT engine. This is partly why most twincharged engines are so small - I believe Volvo's 2 liter is the largest modern one - because they aren't expected to be torquey anyway. It's also why Volvo only uses twincharging on the 316hp variant of its 2 liter, while the lesser 250hp version is single turbo for cheaper build cost and the 450hp version uses a sequential system with an electric supercharger feeding a pair of turbos that all work in unison, as opposed to a parallel system with a belt-driven super at low RPM with the turbo reserved for high RPM.
I feel like we have similar interests and likes in car builds. Its not always easy and almost never necessary but I'm trying to do some different/uncommon/"extra" things with my STi
It's been explained to me that exhaust turbos are free HP & common superchargers are somewhat parasitic HP. But innovations are very interesting indeed.
i remember that mazda comprex or, over complex, system. the input shaft for the mechanical drive side of things had a totally inadequate 6202 bearing that would fail making the system unreliable.
English it's a WEIRD language. Small correction @5:05 : TRI, in tri-power it's pronounced TRY, as in "try doing it". I made that mistake too and was corrected on the spot by a cultured native English speaker. Carry on, Sir. Good job on the videos.

Another cool turbo is an emd 645 turbo it's a super charger until around 800 rpm then the clutch disengages and it works as a turbo
You didn´t mention the ASA Compressor. This is a very efficient compressor kit which rotates with over 100.000 rpm. Real german engeneering.
