BTW - did you do anything different with the impeller shaft?

At the risk of being redundant: Lol - nice!

I've been tied up with work - sorry. What size engine and how much power are you looking to support? 80,000 rpm under load isn't impossible, but it's not easy - unless your power goals are pretty low. One of our members here found a Sea-doo supercharger for really cheap - that might be a...

BTW - I looked at those superchargers too - I think that's an excellent idea, and congrats on the find.

Ditto

Thanks for posting pics of the rotor - I've never taken mine apart; but it's just a "normal" unit. I think you'll like those Lishen cells - they're almost impossible to get here in the states now; though SQCTS on here told me about Toshiba's new SCiB LTO EV car cells - they're pretty...

That fuel cell compressor is a great find; as for the other guy - he's been screwing around with lower power setups for a while now, but I didn't know he was stepping things up. Using twin motors/ESCs is an awesome idea. Frankly, I didn't know that would work. And his fab skills are pretty...

Nice! Can you post pics?

I have an AEM meth kit sitting here. Spraying meth pre-compressor (and they say into the volute) has the same effect as getting a larger compressor - in the words of ProjectFarm on YouTube, "we're gonna test that." I have several nozzles and will test at least volute injection. I'm getting to...

Lol - nice!

I'm happy to test if for you, but it might be a bit (I just finished pulling the engine tonight; I've got a major work project this week) - but I can try maybe this upcoming weekend or next week, if that's ok.

^ I think that's a good way to look at it. What we care about is total power in the system (without becoming wildly inefficient anyway) - that's watts. Duty cycle is an element that lets you get to maximum power in the system. For example, I was running into problems with the VESC setup and...

I did ask the LMT guys about temps, and he said that my temps (about 130-140* F - about 55-60* c was "laughably low.") Considering neodymium magnet start to gradually lose their magnetic strength at 80* c (but recover), and by 100* c they suffer permanent demagnetization; maybe they're using...

Wow. That's pretty cool. I wonder what the rotor's made from.

No. I'm talking about the current being drawn from the battery vs the current pulses going to the motor. VESC and APD both show it in their logs; MGM doesn't. Let me give you an example - if you're motor's running at 50% duty cycle, then power is only going to the motor half the time. So the...

Lol - I've been trying to get that link to work forever - I never bothered to translate the error I would get (it's in German - everytime I see German, I just hear Sergeant Schultz's voice in my head (from Hogan's Heroes) and everything goes blank). Thanks to drother's screen shot, (and knowing...

Thanks! That is the best description I've been able to find by far!

I was told that you don't feel cogging when fewer poles - so my TP Power motors cog pretty hard (6 pole); my Castle motor cogs a little (you can feel it, but it doesn't really make it difficult to turn - it has 4 poles); my 2 pole LMT motor spins smoothly. I'd love to see some sort of diagram...

That's good info. I think since this is the first OEM unit easily available, the CAN data will either be deciphered or a relatively easy work around will be developed. At least I hope so...

Nice. Are you still using drill rod?
