Great to see you again brother! I love the AI nonsense. Got some good laughs! Will you be putting your electric compressors on the market? I need to twin charge something and have enjoyed watching your journey. God bless! Слава Україні!

Why not quickly bolt another e-charger on your current car in compound setup. Then use something cheap like a draggy meter to extrapolate the power gains? Would be more relatable scenario for the masses and be heaps cheaper than buying a dyno and setting up some huge triple compound setup no one will over do? Meth injection between the stages would also be great. Also wouldn't smaller motors make better use of the e-charger? Boost is more efficient than cubes and compression (to an extent) I'd think something like a modern 230 cube straight 6 or similar smaller motor would allow you to run much more boost. Just a suggestion, love the content.

It makes sense why the intercooler vs. aftercooler has such benefits. Regain the air density after the first stage of compression and then right into that second stage. The increase to the boost at the intake manifold should be noticeable.

Great video

Yes, torque is a force. 1ft-lb is 1lb on a 1ft lever. Torque: How hard you can twist something. Horsepower: How quickly you can twist it that hard, repeatedly. Car A: High torque, lower horsepower. It'll feel very responsive and quick off the line, but might not be as fast at higher speeds. Car B: Lower torque, higher horsepower. It might feel a bit slower to get going, but will accelerate strongly once it's moving and will have a higher top speed. A Dyno measures torque with a load cell just like a torque wrench. It measures it throughout your rpm range. Horsepower is how fast you can deliver that torque/force over time/distance. Get it? Got it? Good! 🤓👍

= 15 psi

Know someone that built & sold dyno(s). Seems if all the parts/pieces are available, you could easy assemble one. Time wise it may take longer, but guessing it would save drastically on the cost.

Interesting concept... Electrically driven turbo... All the boost, zero exhaust restriction & zero heat sink in the turbo. Much less plumbing, & use conventional N/A exhaust. I wonder if you could connect two turbos on the same electric motor, & plumb one turbsky into the other, for your compound idea. Installed directly in front of a Holley Hi-Ram setup, with a Tick Performance Air/water 'brick' intercooler. On a side note, what do you think about putting a AC compressor on the engine, with cooling coils inside the air/water tank, and add a fuel loop inside the tank. I'll bet the AC compressor would cool the cooling water, cold enough that you'd need to run antifreeze in the tank. I suggest this for two reasons... Cold air is denser air, denser air has more oxygen per cubic foot. More oxygen equals more fuel, more fuel, equals a bigger bang. Hope my description isn't too complicated with all the 'cool's' used to describe what I'm talking about. I have one more suggestion, as you are exploring high boost pressures. Typically, high boost suppresses the spark plugs ability to generate a large, hot spark. I have a simple way to turn a MSD 6AL ignition from a High voltage, low amperage (conventional pulsed DC spark), into a 'plasma' ignition source (high voltage and high amperage). The spark kernel in the plasma spark is exponentially larger than a traditional spark, therefore, the fuel burn will happen faster, which will reduce the necessity for timing advance (advance timing is actually a drag on an engine, as ignition spark before TDC, the early explosion is trying to slow or reverse the piston, which is a loss of power). I have a short video of my demonstration of a plasma ignition system you can view here: kzbin.info/www/bejne/eJXEnHikbpd2l7M

I'm at a loss. You can compress the air more yes but there isn't more air......🤷 More air=more power

There was no mention of the air volume at the atmospheric turbo doubling in a compound turbo setup. Equal size compound compressors would typically be a triple turbo setup. 2 into 1. Makes the sizing easy...

BA BA BOOEY BA BA BOOST!

To answer your thumbnail = 15 psi lol. I can only imagine how many think it makes 30 psi cause you’re getting 15 psi from each turbo. Twins just spool faster. Bigger single is technically more efficient but lazier.

Welcome 👏🏾👏🏾👏🏾 😅

I feel like a hub dyno is what you need for this level of repeatable experiments.(and maybe a manual tranny test car)but a engine dyno would probably do it too. while simpler to setup the pluming and work on the engine. would it cost less to build a dyno room for an engine dyno or a hub dyno they if all else fails could probably be sold used.

A lot of great info for boost noobs like me - I never understood the compressor maps. Could you add a text conversion whenever you are talking in imperial units please? It takes a lot of time to get in what units are you talking and then to convert it

I appreciate the simple and easily digested explanation of a turbo map. cant wait to see what else comes along.

Been following your channel for a little while now and absolutely love ALL the content, especially this video since you just answered a curiosity that I've had for a while. I'm HEAVILY into the world of the RC hobby and have been a gear head at heart for the majority of my life. So when I saw your video testing a Castle motor to drive your turbo, I knew this was a guy I needed to keep an eye on. Keep doing what your doing and cherish every moment you get to have with Roger, their lives are far too short

Welcome back Sir, you have been missed. You should check out my compound G-45 1600 + Gtx3576r engine project. 1.2L engine making 1056hp at 5,5bar. Also have made my own engine dyno. You should definitely go in that direction to have your own engine dyno at home. Super good when experimenting 😊

Hey, our stuff is so horribly wrong. It’s almost comic.

nice to see you back

Welcome back Alex. Welcome back Roger. You're both like compound twin turbos of positive pressure into my feed ;)

Cant wait

I atill like the old saying "horse power is how fast you hit the wall, torque is how far you take the wall with you'

NICE SHOP CAN'T WAIT TO SEE YOU NEW TURBO THEORY AT WORK .

Thanks for the excellent video Alex! I can't wait to see where this leads. My vote is for you to get a dyno! Oh, the places you'd go!

👍🤠🇨🇦

Can't wait for testing!!!! Good luck!!!!!!

Good to be along for the ride 👍

So, cutrently have a 55lb/min turbo, snallish for the engine. Add one of the electric tuebos feeding it in a compound matter. So, snall exhaust driven turbo spools, electric tuebo kixks it. 3kish, nakes power. How would you go about sizing the electric turbo?

I was where you are... I was thinking about the next evolution of my Mustang. I had come to the compound boost side of things... I wanted better drive ability and a better top end as well. Was looking at a smaller turbo and then a huge turbo to blow into it. But I decided to scrap the idea... I think compressed air supercharging is better. From the info that I found, the CAS makes more power for each lb of boost. At 4500 psi, divide that by 14.7 equals way more atmospheres than we'll ever be able to use. So yeah, gonna take the easy route. Plus, way cooler charge temps. And less resistance to fuel types.

Can't wait to see what you do, especially if you've got your meth nozzles in all 3 to keep the temperatures down and efficiencies up - keeping that delta-T to a minimum would be huge in something multi-stage like all 3 of them at once

3:25-ish HP is a TQ rate, in fact; in every 4-stroke engine in existence, they are equal at 5,252 RPM. **BLAKK MAJJIKK**

Great to see another video from you! It’s been awhile. Let us know when you go to manufacturing. I’ll buy a kit from you

When I saw the title to this video I was like "boost doesn't add!?" Glad you got settled in, I vote for you to buy a dyno! 😎😜

I deeply loathe you Alex - if you have one turbo blowing into another, does that qualify as a "turbo 69"??? 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣 (one of those times where something you understand well enough to know what's going on, but you hear it phrased in a way you hadn't thought of, and it provokes your thoroughly-human side) And glad your peeps are coming around. Good year for them coming up. It's been a long 13 years, particularly these last 3, but it's coming around. Can't type names or comments go away **poof**

I held my breath as long as possible, no in reality we all knew you were otherwise occupied. I would love it if you collaborated with nivlac57 on one of his 4.2L 6-cylinder creations. An electric boosted 6-cyl in the 8's would be so cool.

I like RC motors and BOOST

I know a mechanical engineer that can't wrap his head around torque doing no work.

What about Kwh on a hub dyno what does that show 🤔

More accurately, gear reduction can multiply torque. In other words, a higher horsepower engine can be geared to gain more torque. Gearing a higher torque engine cannot gain horsepower. Torque output at the wheel is the what is actually accelerating the car. F=MA, Torque=F... Gearing does have associated losses. So ideally you want the least amount of gearing to achieve the output torque you want.

Welcome back!!!! Looking forward to the testing love seeing what you come up with.

Love when you upload! Always eye opening

hell yea I've been waiting for a new vid!!!!!!!!!!!!!!!!!!!!!!!!

Awesome great job whenever you put out a video, I will be here to learn something from you, I had some friends around watching with me and I guessed 40 psi and they all said WTF how did you know that? I just laughed and said I am going to do this one day. Great job! What psi are you shooting for? 20?

odd question, but as a cheap bump in power would an EDF blowing into the electric supercharger be worth it? they are pretty cheap, use less power than the big centrifugal and even at a 1.2 pr it could see nice gains overall for the price. another aspect would be the ease of getting parts, and the wider range. I've seen people try to EDF an N/A car and get a few percent gains but compounding might be something interesting to look at, just throwing out ideas lol.

Welcome back! Glad to see Alex Labs up and running 👍🏽 nice AI imagery 😂

Hell yeah brother.

AWESOME VIDEOS! INFORMATIVE COMPARISON .PUTTING TOGETHER SIMILAR STYLE ELECTRIC BLOWER ,ADVANCEMENT IN MOTORS AND BATTERIES SEEM TO BE ON A SERIOUS POWER CURVE OF THEIR OWN .

That is a great idea love the video. Any way to get higher amp output? Wouldn't only half amp charger take a very long time to charge your batteries?

Hey man, I know it’s years later but do you know the vacuum line size for the ford bypass valve?
