Thank you;

Jason (The guy who's been driving my car when we test these things) keeps trying to get me to run no prep with my car. I would if I wasn't building a house 1600 mi away. We will do some fun stuff with it though. If you haven't seen it: kzfaq.info/get/bejne/iLpggJtp3a7efoU.html I agree with your point.

I would love to chat with him he is running 4 motors in his land speed record vehicle. I do need to figure a foolproof way of running multiple motors at the same time. And he should have the answer!

I've bin researching multiple motor rcs for 6 years. Just run a splitter at the signal input and run as many as u want. I've seen 4 from Kevin and many other speed run guys do this.

I just came to comment the same thing!

Thank you for the kind words!

Yeah problem is that motor won't handle any boost. They like to shoot rods out without any boost never going to work

@@randalleldridge5667 we'll see, I'm not opposed to changing it up to lower the compression to allow for some boost. Though judging by how light it has come out I think I'll leave it NA and just make up any power I need on the electric side. With everything in it's almost lighter than a Miata without any weight reduction like skinning the trunk or lexan windows.

Thank you! You too man. I'm back in NH now but would love to move again. Take care!

@@davidreith8093 right on brotha , yea I still have family up there and I now have my own family (wife and 2 kids) and they are all from NC and I have shown my wife NH 1 time for a vacation but only had 3 days ... so now I want to take my whole family up there to meet my other family and see how beautiful New England is and for the kids to get to do stuff inthe snow cu, we're I live in NC (on the coast 20 min from the ocean) it has dusted snow I think 2 or 3 times since I moved here in 02 lol ... much love n respect brotha peace stay safe and have fun ... ps I definitely following ya build now brotha ... do ya have IG ?

I'll have to look into that. These motors run on a max 50 volt system. Though I don't think (but I don't know for sure) that the Ram setup can output the necessary 350 amps for a single motor system (a twin motor like in this video would peak potentially around 700 amps).

I'm sure that in-car charging is practical. The amount of time one would spend in boost is so much less than the amount of time one would have recharging the packs.

@@AlexLTDLX Exactly, and these newer cars with auto start-stop already are fitted with capable capacitors I believe so they seem very achievable/realistic for to me at least

When I first took that video I sent it to my cousin Dan and he said the same thing 😂

but he also tested the TorqAmp with success. Before there was also ARC Superchargers and Phantom

We've already made about 800 flywheel horsepower at the track: kzfaq.info/get/bejne/iLpggJtp3a7efoU.htmlsi=XgvV71fQN0k_n_FS For the record, it takes about 34,000 watts to do that - more than your average house.

There’s nothing wrong with dreaming. I’d love an electric turbo/supercharger. An electric boosted turbo would be interesting. Or a turbo boosted electric turbo/supercharger.

I built an 88 blazer mud truck with a 5.7 tbi , I ran three car batteries to power a fan / turbo style set up , that pure redneck experience was a success,

That's a good question - there's a balance between available motors, rpm and affordable superchargers. This seems to be the sweet spot.

Yeah use an old semi turbo

Thank you. I like your user name. lol.

I want to do this, it is just an issue with getting a small enough unit to fit in my engine bay.

I lived in Charlotte, NC and had it dyno tuned at Hawks in Easley. I now live in NH though. And even our cities are small 😂

yes

@@AlexLTDLX Thanks, I will look for you guys on the form and if I can offer any assistance to further you or David's goals I'd like to help.

Thanks - yeah, I'm having some issues with web guys... I'm working it out as fast as I can get them to work - please bear with me. I'll reply again when I'm sure it's working.

Thanks and welcome

You want to hear compressor whine? Here's my car when it had the Whipple on it running 9s at the track on pump gas: kzfaq.info/get/bejne/et12oceLxpa3g4k.htmlsi=z8WAfSm4WVopwSyK It took closer to 70-80 hp to drive the blower. That's too much whine - it gets annoying after a while. Here's my electric supercharger running just as quick, with much less boost (much more efficient), and you can only hear it winding down: kzfaq.info/get/bejne/iLpggJtp3a7efoU.htmlsi=0ZdGOIWMnBLk27f2 And even the electric supercharger was making 44hp at that point.

@@AlexLTDLX so true yep it takes that much

Try getting is from Speedmaster directly - www.speedmaster79.com/P-2-Centrifugal-Supercharger-Without-Gearbox

Maybe later. A bolt on 6.2 with a cam that is aggressive enough to make 500whp is close to 8k or more all in...this is 2,700 so far. I can always go larger displacement down the road too . The hard part of the swap is done.

Yes

Yes 2028 800kv sensored motors running @ 12s off of Max4 escs

IIRC, he was using starter motors, right? These new brushless motors are in a completely different league.

@@AlexLTDLX I was new to Miami in 2006, so by then he was transitioning away from the electric stuff. I worked in Kendall as a machinist and he'd stop in to our shop and have me machine turbo housings. Cool dude. At this point, the technology for the etc is too accessible to anyone. It would be tough to make money and be a standout company with this type of product. Aren't the Chinese already making these?

@@Cookie-Dough-Dynamo plenty of people are making these, but the real question is how many of the ones available are not a money wasting gimmick? The biggest issue with electric turbos are the fools that are flogging them as some kind of magic bullet. Usually they are egotistical people who ignore physics and fudge the numbers to show that they work, completely ignoring the facts. Like making wild efficiency claims while completely ignoring the power source in the equation, but they are not interested in the truth because it is not convenient. Some of them do seem to produce limited results, but they are generally wrapped up in a good layer of BS.

More than likely, no. Extra air is extra air, and you need to add more fuel for that somehow. There are mechanical ways to do it, but it's still tuning, just not with the ecu.

@@ScootyPuff_Jr If it's a small enough amount of boost, the fuel injection/oxygen sensors should be able to compensate, shouldn't they? Especially if I put in high flow injectors and pump. I'm just looking for advise and I appreciate the information. Can you point me to a link that can help me out a bit better? Is there any DIY software for tuning Chrysler ECMs? Thank you.

adding higher flow injectors requires tuning. At idle you would be super rich if running the stock fuel map that is for smaller injectors. The only feasible way of doing what you're trying to achieve would be this: im assuming a jeep 4.0l has around 18lb/hr injectors. Grab some 30% higher flowing injectors, 24lb/hr? and run e85. It might not blow up immediately then with a small amount of boost, although probably wouldn't last long. Also, i believe a 4.0l jeep needs a valve that closes during boost to the map sensor. Another words your map sensor can't and won't measure anything other than vacuum. Maybe there is a 2 bar map sensor out there that swaps into a 4.0l jeep, but then that would require programming to work correctly.

@@pd2340 I see. Well poo . . . . I was hoping it wouldn't be that involved. Oh well, that settles it then. Time to retro-fit a Magnum 360 into the Ol' WJ.

Castle 2028 800kv. And I'm using hobbywing Max4 esc's

They would probably create a restriction. We're literally talking tens of thousands of watts when these things run.

I just left the comment but my Uncle used to make custom drag snow machines in Bc about 17-18 years ago and he would rig up dremmel motors to the turbos and it became very popular and kept secret in the community

Yes, it is. When I finish my move, I'll be experimenting with different universal controllers that will allow that.

No - we need the rpm. The more gearing up you have to do the bigger and heavier things get.

Eventually you just end up pushing the compressor into choke. I2 motors is sort of a sweet spot. But nothing stops someone from running 2, 3 or even 4 of these units provided you have the room (and your engine and driveline can handle 2,000 hp).

Generally a little thing called a point of diminishing returns. It's like those who think why not just put in more electric motors into an EV. Well because you need to add more controllers and more batteries to support those motors, now you need more hp to move the increased mass, so you add more motors to produce more power, and round and round you go. The answer lays in making the motors more efficient. Belts / gears all consume power so the more you have the greater the parasitic losses.

You can, but everything starts to get bigger and heavier very quickly.

No - those are limited to 200 hp. We've made as much as 800 hp: kzfaq.info/get/bejne/iLpggJtp3a7efoU.htmlsi=nWwC6hxBNPvzczw8

Cost and rpm capability, mostly.

kzfaq.info/get/bejne/iLpggJtp3a7efoU.html You won't see that kind of gain from 6 psi from either a turbo or a supercharger.

A big car alternator can provide about 2,800 watts. This thing will draw ten times that amount - 28,000 watts (I've had a single motor unit up to 14,000 watts).

@@AlexLTDLX thank you for your reply!

@@AlexLTDLX how long do you get on a single battery charge on your current setup? Like how many passes do you get before you need to swap batteries / recharge

A lot, is the best answer I can give you. I have yet to need to recharge the packs on any track or dyno day. On the street, the packs recharge when not in boost, so in reality, you'd never run out.

@@AlexLTDLX like rechargeable nitrous

Because they're essentially 3 phase ac motors. Unless the motors are mechanically sync'd (it would have to very precise - every degree of timing affects performance), the ESC wouldn't know when to fire the phases. You'd end up with "juddering" and no rotation, more likely than not. It would be nice to find higher voltage ESCs that are commonly available, as that would reduce current draw, making voltage sag less of an issue.

@@AlexLTDLX I have not done any research on this so i could easily be wrong. I thought the Tesla motors are high voltage. Granted they are heavier, but weight in the back seems like it might help? a battery pack or 2, inverter and motor might be to heavy, but it would throw some air. the way that industrial motor and vfd are similar and give more versatility but would probably be to heavy when said and done, but this is "pioneering territory", no? I also mean to install in the trunk, no way you could fit all that in the front. to dual stage, just run a pot off the accelerator pedal to the controller?
