This looks great - when you get things working, definitely let me know and I'd love to make a video with you featuring your build. I also like your packaging of the motor, btw.

Please do so - and if you do, I'd love to make a video with you about your results! Just let me know here in this thread.

That may end up being a heavy lift - you sound like you're miles ahead of where I would be with it. Can you share more of what you've discovered? Maybe some of the software folks on here can offer suggestions.

Wow... just saw this. I did have arduino control but encountered some issues. So I switched to the simple method - two small servo testers, with one being zero throttle and the other being max (or whatever it's set to) throttle, with a relay switching between the two. It's pretty butch, but...

If you do meth injection you'll most likely be ok. The meth would give you a big octane boost. But I would sneak up on the boost and I'd read the plugs. Again, though, you'll probably be fine. I certainly wouldn't try this at 12:1 without either some form of octane boost (fuel, additive or...

"Battery is fully charged" - lol. I think charging the lipos to 3.9 volts is a good idea for a few reasons (battery life, less drop). Sorry about the MGM troubles. Yeah, the Hobbywing won't work with the arduino program the way it was setup - but you figured it out. The Max 4 is probably...

I'm now leaning towards 2 controllers - one based on OBD II data, and the other on MAP alone (with a provision for an RPM based kill switch). That should cover most cars.

Welcome Carl!

I'm glad things are back on track WB. Time for you to make another video - do a comparison before/after your wiring mods. I'd like to see the difference.

Yeah, actually I think it would be pretty easy. Do you run at Bonneville or somewhere else? What is you current hp level and how much do you want to make boosted?

Ok, my first use for the electric turbo was as a crankcase evacuation pump - not as forced induction. At that time, my car had a Whipple supercharger on it and using the electric turbo to generate a vacuum in the crankcase would've been beneficial. But now that I've replaced the Whipple with...

It's better to use your engine's hp and then match that to the compressor map. For example, the P2 supercharger that I'm currently advocating for is essentially a Vortech Si trim: Lb/Min airflow (the x axis) can be translated to horsepower by multiplying by ten. So if your engine makes 120...

GTHound - the rate of change, but as read from a MAP sensor is what I'm thinking about. That would make a "universal" controller truly universal. If someone wants to add an RPM switch, then that should work too. WB Projects - I do think in a lot of applications like yours, you're right - you...

I'm finding C ratings to be kind of nonsense - there's actually no standard for measuring C rating in terms of voltage drop. I've thought about establishing some sort of standard for that in a video, but I can't do the video down here in Texas (my load tester is still up north). Lipos may...

I'm very glad to hear it. Going to 12s2p should, in theory, cut your voltage drop in half. 12s3p should cut the voltage drop by 2/3rds. Of course, I'm not taking into account any losses in the connectors and cables - have you measured the voltage drop across the cables while running? You can...

That would be an interesting project to see.

I'm also wondering if there's a way to control is purely with a map sensor - in other words, if there's a sudden drop in MAP, it turns on (maybe scaled on the degree of drop), but if there's a sudden spike up it stays on unless it goes too high, then it could shut off... Just thinking out loud...

Hi all. Now that I'm pretty comfortable with finding a "sweet spot" setup for the mechanical and drive aspects of these things, I'm starting to think about better control methods. I can think of several: 1. Do what I'm doing now - have it turn on to max power above a certain rpm and certain...

Not yet. I've had a few issues with an arduino in general. I think it was mostly EMF issues (which could be solved), but it could have been code. Now that we have a basic formula down for the mechanical and drive aspects of the these things, I'm starting to think about various control...

Nice!
