    Hey Rob, i used to have the same water but i dont think it was any good and it got lost or scrapped. What brand/model is it? And whats involved with controlling duty cycle?

    If I learned anything from heat transfer during my degree is faster flow is not always better for cooling. You need to find the sweet spot between coolant flow and heat transfer

    be careful with your waterpump on off set up. if its not off long enough, the water does not stop at the rad and has no time to cool

    That car has been so full of failures and issues…how do you end up with a bell housing completely loose…but either way it’s all part of building a car that’s pretty much from scratch…..guess we will see if ya beat the rest of the field ..

    My company uses PWM on our motors which we need to be very precise; it used to change speed even though the oscilloscope was not showing anything of the sort. It was ripple which we mostly removed with a different value capacitor. Perhaps this may help on your EC motor which appears to be changing speed at random points at one point in the video.

    Isaiah is really getting good at talking and explaining stuff on camera. He's come a long way 👍👍🔥🔥

  • OtterConnor

    I bet your electrical system would enjoy a sub woofer capacitor to supply a more consistent flow with less stress on your battery and alternator

    Rob please get rid of this PWM crap and put something better. maybe a PC PWM controller would be better

    1:45 honestly i'd rather have a F20C swapped rx-7 with pop-ups than have a 4 rotor with the flat lights, pop-ups are sacred

  • Toms Tech

    Might be better to have the water pump lower so it can be fed with more pressure (water column above inlet), it'll circulate less air not being at the top of the system so it'll be quieter and live longer.

    Is anyone else on here ready to see Rob get out of the garage and put these cars into action? The Hoonicorn Race was literally the only video of any car driving outside his parking lot. Get these mofo’s to an event! I’m ready to see these cars put some power down instead of constant build...dyno...scramble for event...miss event and start another random project. C’mon let’s see the work play out!

    Sounds like the pwm is shit. Don't use them. We dim led with them they are unreliable. Brushless motors need ESCs or vfd.

  • Anthony

    Be mindful of resting your hand on the shifter between shifts with a strain. You’ll end up causing it to try and cut ignition because it thinks your starting to shift. You’ll probably have seen this on the logs by the time you’ve seen this comment LOL

    While everyone else stays stagnant with their skills and dont try to learn more, there you go pushing the current boundaries and redefining what the limits are. All of these other people spend years learning and you're accomplishing greater goals than most of them wish they ever could. I cant wait to see where you push this in another 5 years. 🤔🤙✌
