    crf450r 45kw race bike build

    it’s a real shame in this power range… 3shul is taking forever delivering cc1000s (and under delivering on order qtys to distribution), Tronic has stopped development of their x24 and x54. At least fardriver can deliver and that guy putting down 80kw or something with a 1081800 with his qs180...

    Street legal Cafe Racer build.

    I'd look at the 3shul CL1400 or even the Tronic X54 which uses TOLT mosfets - First of it's kind (speaking about the whole new X lineup from tronic)

    Mid-sized Motors = Pathetic Choices

    Some folks getting 50kw+ with the sotion mg138f water cooled. I think some guy is getting 60kw + with the QS180 80h. I've been watching DHX for 3+ years and almost nothing on the peregrine line. I think the 40 or 60 was still $2500 USD or so.

    30s not charging?

    Hey guys, I’ve got a 30s2p 111v 50ah pack I made from some LFP cells. I’m using a DC power supply (120v/3a) for charging and can’t seem to get it above 100v or so. Do I need more current to push into the pack to get it to 100%? Stayed at 101v for about 3 hours so I’m thinking something is...

    Oil cooling a motor with transformer oil/dielectric fluid - the next frontier?

    I do believe there are some threads from 2007-ish of people filling their motors with oil to help with cooling - Toyota's hybrids drip oil on the stator. I'm not certain if they are using a separate oil for that or what but perhaps it could be a starting point.
