Full throttle Electric Supercharger Build Thread

[bfrank1972]

This thing definitely has my attention - any prediction/hypothesis on what would happen on a track day? AutoX?

For instance, what happens as voltage drops - does it limit boost or just shut itself off completely. At some point in a full on DE event it would just run out of juice completely, what does it do?

Battery/motor overheating risks? Protections built in?

For track days could it have an 'idle' mode that it just spins in low speed 'non-restriction' mode? Or perhaps lower max boost level to extend battery?

Thanks

Thanks that answers a few of my questions - I also need to spend time digging through this massive thread (sorry wasn't trying to be lazy ). Basically just trying to gauge what happens when I go to my local DE events - I'd be happy to run it without the supercharger, so I'd probably just shut the thing off. AutoX it should be enough for a run - I also very much like the idea that this thing is easily uninstalled. Would be huge fun with it on an AutoX course, but obviously puts the car in a tough class, so I'd like to be able to pull it off and just run STX competitively when I want.

Some 1st - 3rd, some 2-5th as well, I forgot I do have na pulls between us well a but I lost those.

Waiting to hear about pre-orders....

You can count me in too!

Very good questions, but from what I can see so far if one were to flip it off when it gets low to let it charge back up for straights it would still have a great deal of usefulness on a track with 2-3.5 minute or so laps. I think with practice one could learn to use it effectively even on the track (You won't be 75% or > WOT the entire drive) I read the entire post and did a lot of my own research and I think this application might have a good mix of usefulness for the predicted/expected price of ~$1500. It's not a dream come true solution, but I think 30Hp and 55TQ on demand will be fun and useful in many situations with the right tuning. Keep in mind engineering phase not even in the hands of master tuners.

You don't even have to shut it off, just don't go over 80 percent physical throttle.... That's still 100 percent throttle to the ecu anyways.... You can test this out yourself just go 50 to 70 percent throttle in 3rd gear and then go 100 physical and see if you accelerate more.... you won't.

This thing is a absolute blast on the street. Just point and shoot as merging or passing cars. Its a very noticeable difference.

What was once a slow car and could be overtaken by a Camry or Toyota sienna is now faster than many cars on the road.

Adding 80 torque is increasing the total output by almost 60 percent

that's interesting.

Here's a question: with a few of us wondering if the unichip could be utilized to run this I was wondering if the motor controller on the phantom was variable.

The unichip reads the throttle position so in theory we could use the unichip to control the speed of the super charger that way it's not full bore on when activated. I.e variable speed on the supercharger based on throttle position.

You could utilize the unichip to run this, but you would need to alter the reading to pass through the unichip first. What I mean by this is for instance, you could controll boost with the boost controller built into the unichip, I don't see why you couldn't control the load via an input signal into the unichip. May be an interesting theory.

I'm still new to this whole theory, but have been paying close attention. I like the idea of the electric supercharger

[bfrank1972]

Fenton, looking at your dyno charts I don't doubt it. At SL I'm thinking the torque curve is starting to look similar to my old E36 M3 (but in a much much lighter vehicle).

So I'm sifting through this entire thread now, and have read the specs on Phantom's website (what I could make of them). To circle back to one of my original questions - say I leave the thing on and just run it wide open at the track. I mean run the hell out of it. What happens when you completely deplete the batteries? Anything bad? Does it eventually start placing heavy load on your alternator or does the control module shut things down?

I know we're in the development stages here, just curious. Sounds like you guys might need a 'sea level' tester. Ahem cough I live near the beach

A few of us have inquired about this but have never gotten a straight answer. They were able to setup an 'idle' speed where the charger spins just fast enough to not cause a restriction. But I have a feeling it wasn't a setting in the firm ware or anything that is continuously variable. It's probably hardware changes that allowed them to do this.

If you are going to race this thing, wont you have done some serious work making the car lighter? 50 pounds of some of the new LiPo batteries should get you through a race. Some of the power systems the car-stereo tards run would probably power this thing for a week.
