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!

Good to know.

Best of luck WB! I'm sure it'll work out.

Welcome! Your requirements seem ideal for and electric supercharger!

I'm in Texas right now, so I don't have to exact size(s) available, but there's a size of pvs electrical conduit that those cells fit in perfectly, and there's a tap size that happens to fit into that conduit perfectly - which I bought (because of course I did). That makes making very high...

Welcome! I actually have 180 of those cells. The biggest issue is the current capacity of the strips. I have yet to figure out how to do it where they can legitimately handle the kind of current we need. I have an idea (and bought some parts), but am still doubtful. I do intend to do some...

I was able to interview David about his project - check it out:
