Brother, love the channel just found it. Hey, on the echargers-- I know this isn't the same video- but I found your channel in the process of going through the same process and looking. Ironically, I came to many of the same conclusions for components and setups. A few things I've stumbled on: one is MHEV batteries. Many are 48v. Not necessarily cheap enough *yet* but they will be out there more and more soon- I expect the ebike and hybrid modders will snatch them up. The other is budget motor selection. My two possible applications are only going to like about 6psi at their peak output. One is a Yota 4.7 (that will be a while, still no really good end user tuning available) the other my 6.1 Hemi. Which I need to build my brushless pump/FPR setup first (another cool project you might try? simple of course, but allows using one big single pump, closed loop control on a returnless system) To get to the point- Electric Lawn equipment can contain some beefy motors... have they been explored? I assume you've been down that path and decided if you need the beefy controller anyways, might as well have the RPM of the motor to not have to re-gear/ratio it. But an example is the 40v Kobalt push mower motor looks massive. Works well in Ebikes. Capable of 1500w, 12000 rpm no load. Seems torque biased, but it's a really shallow motor as well, designed to take a LOT of load, with big shaft size etc. Might be a better direction than the hobby motors. (I'm an RC guy myself- it's what got me re-interested in the more EE aspects of automotive tuning.)
If you haven't seen the drag test where I overlayed the e-charger power draw in watts, check it out: ua-cam.com/video/nlTVHkfSQXM/v-deo.html We're pulling well over 30,000 watts; with peaks around 35,000 watts. I'm thinking the most cost effective approach may be multiple 1/5 scale RC motors. The LMT motor I'm using is pretty awesome, but it's also pretty expensive, long and hard to get. Ideally, if I was an OEM, I'd design an integrated motor/impeller shaft - that would be the most compact solution. Thanks for watching and commenting!
@@AlexLTDLX Definitely! I'm playing catch up. Go back and forth on a few engineering channels and come back to re-evaluate and test. My fuel pump module is next, then some oddball stuff for my Lexus (a system that looks at speed/steering to turn on corner lights, ala some German cars early 2000s. Silly, but useful application of ditch lights). I certainly see why you need those hobby motors, and the output is staggering for the size of them. Simply insane. It's making me want to do a go-kart with one geared down, and just deal with the heat. Learning a ton, I'm in the SE, Huntsville area- getting to that "project" time of the year, I'll have my eye on your channel, and dig into the forum. If you're in East TN by chance I know a guy up there you might want to connect with. Also, you should DEFINITELY send a demo of your setup to Cleetus and Co. in FL, their Echarger tests on the poor slobalt generated a lot of interest, it would be a fun build-off episode they have the means to produce as well- no doubt would get some more rev your direction. Happy Thanksgiving! And thanks for the great content.
@@AlexLTDLX hello Alex I wanted to share with you the following Supercharger parts are much more expensive than turboes and the options are limites I found these 2 stage planetary gearboxes with claimed 70:1 ratio ua-cam.com/video/GFMSQxwEY68/v-deo.html Off course other ratios could be found but the idea is that it is possible to use cheap chinese turbo compressors simply because we can spin the rpm or even make cheap pulley driven superchargers Off course you thought of this but it seems realistic with these gearboxes Please let me know what you think Edit: i found outs several of them in drills
I'm only about 3100 and 2500lbs in my 2 glide SBC setups but those cruising trans temps are pretty high? Esp. if its only 45* out? Where are you taking the measurement? Have a decent cooler on it? I see 130's -140's cruising and my converter is VERY loose. PTC 9.5" spragless core with a 20-5 stator. Will stall well past 5k if I let it on the brake. After a pass I may see a bit over 200 on the return road, but then it starts cooling off from there. I do run a deep glide pan with large coolers and fans. May be something to look at anyway.
I agree that it's a bit high. Towards the beginning of the driving part there's a shot of the existing cooler. I'm going to move the cooler from in front of the radiator and put a couple of small fans on it.
That wouldn't make as much power. We're getting an honest 200-250 hp from the electric supercharger; if applied directly to the flywheel, we'd only pick up 44 hp. On this next dyno test, we may pick up closer to 300 hp just with the tweaks we've made.
Thanks for the kind words - I've had this thing for about 25 years at this point - they'll have to bury me in it! Thanks for watching and commenting, Brandon.
I now run Jones Maxflow mufflers. They're quiet, fairly low tone, but they lack "bite." But they're good for driving and I did an A/B/A test (mufflers, no mufflers, mufflers) at the track when I was running the Whipple - even at ~800hp, there was no measurable difference.

Right on! It's alive!
cool Alex, looking forward to next dyno session! have a great Thanksgiving!
Thank you sir. A great Thanksgiving to you and yours as well!
@@AlexLTDLX hello Alex

Alex are you still 4 lug? Are those Bogarts? What brakes are you running?
Love seeing this thing develop, can't wait to throw an electric turbo on my subie 😂

Have you also considered making a tri-mgm starter which spins the flywheel instead of forced induction?
That wouldn't make as much power. We're getting an honest 200-250 hp from the electric supercharger; if applied directly to the flywheel, we'd only pick up 44 hp. On this next dyno test, we may pick up closer to 300 hp just with the tweaks we've made.
Love your ltd so much

Is this still with the Walker exhaust on or something different?

should be a hoot
