Hi all. Now that I'm pretty comfortable with finding a "sweet spot" setup for the mechanical and drive aspects of these things, I'm starting to think about better control methods. I can think of several: 1. Do what I'm doing now - have it turn on to max power above a certain rpm and certain...

Do you all think it might be worth trying something like these: https://amzn.to/3XYnqIM I don't think they'd make a lot of boost, but maybe stacking several together might actually be worth something; particularly relative to the low cost. Do you think it's worth exploring? It'd be very easy...

Just wanted to share what I've learned the hard way. Higher motor pole count means higher electrical RPM (i.e. eRPM). Actual rpm is calculated be eRPM divided by the number of pole pairs in a motor. So if you have a 4 pole motor (2 pole pairs) running at 80,000 eRPM, you'd be turning 40,000...

Hi all - I've been innundated with all kinds of stuff. Life was supposed to ease up by now, but instead things got even more chaotic. But I'm still doing my best to keep up the research on my end. This Black Friday I took advantage of another sale on a P2 supercharger (for those counting at...

We were hacked by ruzzians and down for a bit less than 48 hours. You'll notice a number of lost posts (mostly the most recent ones) - we recovered the vast majority of posts, and are now back up and running. We've taken some security measures, but if you have suggestions how to keep the...

Hi all, So I've been pretty hell-bent on starting with a supercharger instead of a turbo. We've had success with both (WB Projects with his gt35-based unit; and me with my Vortech (and Vortech knock-off) units. But looking at compressor maps for some of the bigger turbos, it looks like those...

Hey guys - since I'm so good at time management, I just wrapped up working on the car to get it track ready. It's now just after 4 am my time. But this cannot be overstated - WHAT WE ARE DOING IS DANGEROUS. IF YOU CHOOSE TO PURSUE ELECTRIC BOOST, YOU DO SO AT YOUR OWN RISK; YOU AGREE TO HOLD...

I'm working on trying to get this thing (i.e. Sledgehammer) to the track this weekend - but weather's not really cooperating. It looks like I might get rained out. But I get TONS of comments like, "I want one" "Where can I buy one," etc. This last comment I just replied to put me over the...

Ok, I may be going full nerd here. My daughter's been into watching Battlebots for the entertainment factor lately. When I was a kid (I was 12), I built a remote-controlled robot for the "Olympics of the Mind" competition. I named it "HAL 9000." It could move around, had an articulating claw...

I know we probably don't have a lot of drag racers on here, but I'm getting the car ready for dyno and drag tests, and of course in my last drag test (over a year ago now - where does the time go?) I destroyed my slicks getting the opening burnout shot. They were old and needed to go anyway...

Since I'm getting frustrated with the VESC/P2 setup (the P2 part works fine; the VESC is giving me a lot of issues), I'm turning my attentions to the Sledgehammer MGM/LMT setup. My 30100 LMT motor is a 2 pole deal with 6 connections on the back. It spins easily by hand (unlike the TP Power...

I have mentioned it before, but the reason why I have a hard time saying words like "electrical" properly is because I learned to speak Ukrainian before I learned to speak English. Both my parents are from Ukraine, and at that time the Ukrainian language was illegal in the USSR. The russian...

I know this is the tech section, but I'm invoking my right of jus primae noctis (well, not exactly right, but you get the idea - also known as "droit du seigneur" for WB). It has begun:

Hi all. Shot an impromptu video tonight that has info that you all might find useful:

I haven't even powered the thing up yet. To be honest, I'm scared to power it up. The documentation is sparse, information that is pertinent is hard to come by, you have to spend DAYS parsing forums and guessing. Yes, it may be powerful, but since many settings are followed by the warning...

May 2022 be better for all of us! That said, I know a lot of us are being held up for various reasons - weather, waiting on parts, etc. I will confess that the last few years have been tough for me. But things are getting straightened out and I'm hoping to see a lot of progress not just from...

I know that SQCTS and cmoalem have both jumped on board the P2 blower bandwagon and I took advantage of Speedmaster's black Friday sale and ordered one myself. SQCTS already has his running (direct drive) on low power; cmoalem is going the timing belt route. I wanted to start a thread devoted...

While I figure out my next moves regarding ESCs and motors, I figured it might be time to make our arduino controllers a bit more flexible. As many of you know, MkngStffAwesome on here is responsible for the original arduino code. It works, it's simple and arduino nanos in particular, are...

Hi All, WB Projects has been talking with me about his project through PMs. Since this is a "let's all learn together" type of forum, I asked him if I could move our conversation to a thread here. I'll start by going be to a point in our PMs that makes sense. WB Projects: Good new for me 🤘...
