    Rotary E-boost

    Rotaries and e-boost should be fun. I can't immediately think of anyone having done a supercharger on a rotary, although I'm sure someone has done it.

    I bought a Hobbywing ESC - Is this our Holy Grail?

    I too was doing the simple watts = volts x amps. 88 Fiero; I also wasn't saying that it was rated for a continuous anything. I figured a 340 amp pump might be an ok thing and yes, logging temps would be very important. I'm personally straddling the fence on this as a cheap option and 'see how...

    I bought a Hobbywing ESC - Is this our Holy Grail?

    I would run cogged and not a ribbed drive. The tension to make the ribbed belt work is something these motors (specifically bearings) weren't designed for. Further looking at the numbers, it seems the 70125 could run 15kw at about 340 amps. Would be interesting. I had looked at it but it's kV...

    I bought a Hobbywing ESC - Is this our Holy Grail?

    I mean if you're that worried about your charge air temps being at or less than ambient, yes, you'll need some thermochemical one way or another :LOL: Plumbing your AC into your intercooler system or even just inlet path has been done many times before. I'm reminded of a particular Dakar project...

    If doing a centrifugal, an air to air would also be another potential option and then just less mess with a heat exchanger, water pump, hoses, etc...

    I bought a Hobbywing ESC - Is this our Holy Grail?

    You are 100% correct on that. I'm also well aware of it. Belt drive also isn't an option for my project as I'm doing an electrically assisted turbo. The biggest issue for me will be getting the alignment correct and the spark eroded shaft end that will couple to the compressor wheel. Potential...

    I bought a Hobbywing ESC - Is this our Holy Grail?

    Hello again. So I've been digging a bit more and it actually seems that this EZ Run has braking which you can program. From what I see from all of these larger car and scooter oriented ESCs is that they all seem to use regenerative braking as their brakes. Alex, want to add some regenerative...

    I bought a Hobbywing ESC - Is this our Holy Grail?

    While I don't have exact belt temps, We ran ~10mm wide cog belts to drive 5 stage dry sump pumps on endurance engines with no actual cooling (see 24 Hours of LeMans and Daytona 24). Shoot, in the Ford GT is was slammed up against the bulkhead and had a full undertray. We also used them on every...

    So I'm the new guy now.

    Hi all, Checking in from North Carolina. I've always been a gearhead and professionally got deep into design work, specifically engine design. With a background as a mechanical engineer, I'll say I'm good bit allergic to electronics and haven't touched anything EE related since college. Let's...
