Just FYI, the JT-trim was available as a V3, and is the same as the Novi 2200SL/Vortech Ti. You can buy a fancy billet V3 Ti trim impeller from JB Performance, just like your last one, and all you need is a 2200SL/Ti volute to go with it, and it will all swap right on your existing V3 unit. You would end up with -basically- a V3 JT-B. It would also be relatively inexpensive (compared to a new JT head unit.

That was a good explanation of the compressor maps, it would be great is Richard Holdener watched these, I’m sure boost man himself would love another form of boost

[Sympatiko]

i've been quietly following your build im a novice but you are an inspiration... thank you for continuing what is American, innovation and application. God bless you

I've been watching your videos a few months and now I'm REALLY hooked. This project is beginning to show real promise and the level of technical detail is really enjoyable. I was working with BLDC motors in automotive applications about 10 years ago and electric supercharging was always a subject of conversations back then. It's great to see that technology is beginning to bear fruit and I can't wait to see how things develop from here. Thanks, Alex. I have a feeling that in a year or so, your expertise will be in demand among the drag racing fraternity. Good to see MGM are still going strong too. Used to have one of their ESC's on one of my RC speed record cars. ;-D

The meth picture can’t me off guard🤣😭😭another great video man I’m learning so much can’t want for more future videos

What about moving this turbo closer to the intake manifold. Since it's no longer belt driven, it's logical that you can put it anywhere. Less turns to go through the less resistance of air flow, and if it gets moved closer to the power source the less loss over distance in the cables. Does this sound like it makes any sense?

Alex, you know what would be the coolest sheet to build? An Air centrifuge. This is actually one of my dream projects. Been researching it for years, and yes it possible, and will produce an air stream around 50% O2 purity with plenty CFMs, with far less power then typical forced induction requires. As I'm sure you know, the atmosphere is mostly nitrogen at 78 freaking percent, only 21% oxygen. The Nitrogen and O2 are not in any way bound together, its simply a matter of separating the two....somehow. The atomic weight difference between the N2 and O2 is enormous... far far greater then Uranium235 and uranium238, which is currently separated by centrifuge, it's how uranium is enriched, by heating till vaporized, then centrifuging, throwing off the heavier U-238, as the U-235 is the target. The entire reason Nitrous is so effective is entirely due to the fact that NOS is 36% O2, instead of 21% normal air. So a simple centrifuge would essentially be an onboard unlimited NOS tank. But instead of supplying the engine with NOS level O2 (36%) and melting the pistons. You have the centrifuge output around 30% O2, or whatever 40% if you want, a german achieved 51% O2 stream. They are a nightmare to build, as the periphery of the rotating chamber, has to achieve around 500 m/s, in order for the O2 and N2 to separate.

I really enjoy the technical walk through of the optimization. It's probably just as enjoyable as all the motor tests and dyno videos. I've been doing a similar thing with a homemade windmill of going full send on the calculations and testing to determine roughly the same things (rpm and efficiency given a wind speed and a coefficient of performance curve vs. tip speed difficult to do the math, but I'm up for a good challenge). I also built a effectively a brushless motor as an alternator. It has 12 coils in 3 phases, which means I can wire each phase in a 1x4, 2x2 or 4x1 configuration to change the current and voltage at a given RPM. The magnets are on a 4" diameter barrel and are 4" x 1/2" x1/2" N52's. There's about 5 lbs or 700-800 feet of 17 gauge wire in it. It's about 15 kV and will do 30+ amps at 140 rpm going into a few hundred Ah of Tesla model 3 cells. I also used magnetic lamination steel to flow the flux and a bunch of thermal potting compound.

Thanks for sharing the voltage drop info. I wonder if you've maxed out your voltage on your ESC/Motor/other things. I'm assuming so and I know it would be expensive to upgrade to something higher.

[tomasjones]

Lovin this project. I like that you're looking at efficiency (new impeller & meth). Pushing against choke point is similar to simple electric resistance

[TheWirkkalaShow]

This project is awesome. I just found you last week and I’ve been waiting for this video…see ya next week!

[derekleclair]

Dude!!! I love this. Thank you for continuing and being pumped about this!

Better hair, I think any hair is a huge improvement!

[Lecherous_Rex]

We need a web store made from these projects, use the buying power to get bulk discounts, build custom turbine/housing and electronics sets for your the worlds needs with a central packing location to keep shipping cheap. Honestly now I'm wondering if this could be used for fuel efficiency, imagine charging up the batteries where electric vehicles charge, give fuel sipping motors the ability to pass on the highway. Now all I can imagine is a k series with this triggered by v tec, stopping at tesla superchargers to charge your supercharger. 480 volts dc.... lol

[richardblack]

Awesome. Looking forward to the next one

[vrmgt]

Awesome Alex, keep refining and fine tuning!

[AdamOpheim]

IMHO, call PTC. I see less slip with that 9.5" converter than I ever have on any turbo setup ever in over 20 years of racing. I'm at less than 6% making 900+ at the wheels on a turbo small block. It is also surprisingly loose down low and allows me to get up on the trans brake and make boost. They are about $1200 shipped. Good luck and great content! Also... I found you can run hygard hydraulic tractor fluid. It holds up to heat better and is cheaper than ATF. And tightened up my converter about 200rpm. Its a win/win. Might look into it.

Have you ever thought about using the compressor motor to take the place of the starter thereby potentially reducing complexity and freeing up room? Or would it even be possible to use the starter in tandem with the compressor motor on track day for a bit of extra power? Could the motor be used also in place of the mechanical water pump and alternator and on track day toggle switch the alternator and water pump off so there'd be no losses? Could the compressor motor be used as a drive motor to get you home in case of engine failure making this car a true hybrid? Just some ideas.

🤣09:40 made me think of my childhood buddies jokes I love it

[jpabon]

Keep it going Alex!!! Take it to the max… I’d buy one 👍🏼👍🏼👍🏼

[rafaluiz]

The motor is direct drive or have a set of pulleys on the impeler? Why not make a set of pulley behind the "turbo" that actually you need less voltage to achieve the desired rpm of the turbo?
