    Mazda RX-8 P2 build

    One of the best chassis in the world (no bias here :LOL:) just begs for more power! Certainly looks like you are on the right path -good luck on the journey.

    RX8 Renesis Rotary eSC

    Tested the new motor. Performance is practically identical, same power from engine, same power consumed by motor. I do feel like the new motor will handle higher loads with ease though, so am ordering a larger pulley.

    P2 Supercharger Thread

    I saw the conversation on here but decided to just 'send it' and see what happened. No problems so far. I think mine initially spun more freely than that though.

    RX8 Renesis Rotary eSC

    Shaft size is the same . Got a 22T (at 560Kv) pulley which should give close to theoretical same speed as the Castle was (15T and 800Kv). So it should be a good performance comparison.

    New motor is quite a bit bigger!

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

    Think of nominal voltage as the 'average' voltage of the battery over its useful range. For best results you need to keep battery charged up - but you shouldn't go over the rated cell count for the ESC/motor if you want it to survive.

    Want to build 500Hp electric turbo, people with experience please chime in

    There are 8 different charging programs, none of which were designed for LTOs. But seeing as I couldn't find any alternatives at the time I just bought it and xd my fingers. It could benefit from more aggressive charging but otherwise it works great.

    Want to build 500Hp electric turbo, people with experience please chime in

    I use a 12-48v on board charger made for RV vehicles that I bought off Aliexpress. My Alternator is a stock OEM 100A 12v. The charger is designed to charge while the battery is being discharged and this is how I'm running it. So far no issues at all with that. I have noticed that it pulls a few...

    This is something I'm a little unsure of. The AMPs the ESC records don't seem to corelate with what's coming out of the battery. I noticed that on one of Alex's videos the cable to ESC was flowing 265A yet the ESC recorded 320A+. Maybe @AlexLTDLX can clarify ?

    RX8 Renesis Rotary eSC

    I've seen as much as 260A at 47 volts. The thing is that it seems to me that I'm at the point where there are diminishing returns when putting in more power/changing the pulley ratio. Changing the motor should tell me whether that is in fact the case. Something that many here may not be aware of...

    RX8 Renesis Rotary eSC

    I think I've got the same bug Alex has! Bigger (70125) motor coming to replace the Castle 2028. Really feel like the car has to make close to 300whp for the eSC to make the statement I want it to. This motor should get me close - fingers xd.

    I haven't seen a converted turbo setup that works as well as the P2 yet. Maybe you will be the first .....

    The P2 is the best place to start IMO ..... It's actually a very cheap option.

    RX8 Renesis Rotary eSC

    Did some roll racing with it yesterday. Was thereabouts against most of the cars but not really competitive. Need moa powa! Below was vs 1000+HP Dodge with a big Whipple ..... bit of a no contest but I did stay in front for a wee while. Check out the commentary at the end of the run

    RX8 Renesis Rotary eSC

    Had to fit a slow charge setup to it or it would weld the relay shut and shut down the BMS. Congrats on the ...Maserati?

    RX8 Renesis Rotary eSC

    With some help from an EE I managed to sort out the issues with the capacitor. Saw definite improvements but overall it's only marginally quicker than it was with the Lipos . But sooooo much more practical now with the LTOs vs the Lipos.!
