I'm not sure - most will cut out because they think the batteries are too low. But I really don't like the discharge curve of supercaps. Lithium batteries are far better suited to what we need. At high RPM, which takes a bit to get to (in an actual car), you want maximum voltage - voltage is...

Welcome! I can't say how many times I've tried calculating some of that stuff myself, only to discover that it's math that's beyond me. I just happen to be moving to Texas myself soon - about 2.5 hours from you on the gulf coast...

Hi Wilbur - thanks for following up and no, I actually didn't see your email. Do you remember when you sent it? It's possible I might have missed it. My daughter had some serious health issues around that time (that now appear to be improving, thankfully). Ironically, one of the guys I...

Welcome!

Welcome! The P2 is basically a Vortech Si trim. This is the Si trim compressor map: As far as spare parts go, the bearings are common, there are a number of chinese companies that make billet impellers for these (at really good prices - I really overpaid for my billet impeller). The only...

Severely retarded timing can also cause heat issues. At least it's not a critical issue. Any progress on the e-turbo? (I honestly hate calling it that, but it's just so easy to write...)

Wow - that's really cool that he got back to you. That link is interesting, but it look to be more for developers. I'm sure we'll see products coming down the pike soon enough that use GaN FETs. I've said it like a thousand times, but things like this keep popping up - we're at the nascence...

We should be all back up and running for everyone. As far as the Hobbywing setup goes, I'm going to build a pack out of my Lishen LTO Cells to see how durable it really is; though I'm feeling pretty good about it...

Thx - yeah, I know. I'm struggling with the SSL certificate since the hack for some weird reason.

Did it work to remove the "rev hang?"

Actually... I wrote all that and I may have misinterpreted your question (that's how excited I am about your setup). What you're trying to do is control how the electric supercharger comes on, right? In that case, cmoalem is right on. :) Please post pics/vids!

You should move. Lol.

Good to hear it! It's freaking cold here, I can only imagine what it's like up there!

It's taking forever to process in HD, but here it is (unlisted, until it decides to finish processing):

Just finished the first round of high-power testing with the Hobbywing/Castle setup. We hit 9.5kW continuous and everything held up fine. If we can get to 13-14kW I'm sure it'll support 650hp. Our tests today show the current setup is good for 550hp at about 5 psi. Video coming soon.

It was a black friday sale. $625 is the regular price, and honestly, still a good deal. I just took a quick look and GaNFets and they look to be a potential game-changer. I wonder if the reverse conduction characteristics might be a problem for ESCs and the associated back EMF.

I haven't even heard of GANFets. I'll look into them. Sounds like a game changer.

Every night I put in a few hours cabling/setting stuff up for the test. I've got power, control circuitry (but not cable - I'll make that tonight), current measurement & rpm measurement worked out. Just need to extend the RPM sensor. I discovered a few interesting things: - The Kemet Caps I...

Unfortunately, the VESC just doesn't perform in the real world. I did try running it in BLDC mode too; it just wasn't up to the task. I think a big part of the problem is turning out to be the 6 pole TP motors. That's a lot of eRPM and many ESCs seem to get unstable. WB's ESC did die, but he...

We'll find out. I intend to torture test this thing on video soon. I will say it's a good deal beefier than the small APD ESC; not that that's decisive, but I'm always willing to give the benefit of the doubt. The fliers were downright spindly by comparision (and weighed proably a quarter as...
