Full throttle Electric Supercharger Build Thread

Great ! Looks like the last missing link will be the Work of this system in harmony with the engine change of pace. Probably another programmable ECU which can read the vehicle ECU and command the unit to change Pace as needed, then the system will be very snappy as well.

Keep up the good works guys. Thanks for all your time and works for this new experience

If you want to modulate the electrocharger at varying throttle levels, the implication is that it will be engaged for a longer period of time than just doing a full throttle run to pass someone or embarrass someone at a stoplight. This sounds like the extended runtime that would be needed for a spirited run down a winding road or on a track, using the engine to influence handling. I'm just thinking that at this point in time some people are overreaching the capacity of this system. I like it for what it is and have been supporting it from the get go, I just don't want to see people getting unrealistic ideas of what it is capable of at this point in time.

Let's just make this clear, there's no "pumping loss" below full load since the throttle plate would restrict flow anyways.

Additionally, the motor is limited to 12V and whatever the electrical system can handle, which isn't that much power, so just putting it on full blast will not overboost the engine, and that seems to be what they do.

This thread is too cluttered for me to read the entire thing, but I would be interested in just the compressor (a larger one preferably) that would either come with a larger motor or give me the ability to attach a larger one that can handle a higher voltage input. I have the capability to create my own charging system and control system that would allow for more than just a wot switch.
As great as low end gains are, I don't want a torque curve that drops off. The only way to get around that is to have a setup that can still make good boost at higher rpm's and then limit boost at lower rpm's.

It's 28 volts, not 12. It has its own battery pack that recharges between runs.

Guys, I wasn't trying to say that this should ever spin beyond it's 'idle' speed until the throttle plate is fully open. But the throttle plate is controlled by the ECU with input from the pedal in that car, with no direct connection between them. The pedal could be to the floor and the plate not fully open, or conversely the pedal could be at 60% of it's travel and the throttle plate could be fully open. What I would like to see is full NA power available, unadulterated, at ~ 60 % throttle. You could still do everything you do without ever engaging the supercharger. If you go past 60% the supercharger will start coming on to pressurize the intake manifold. In that last 40% of the pedal travel the throttle plate will remain fully open and the superchargers speed will be ramped up to max at 100% throttle pedal. This will provide smooth power delivery without needing to have huge power storage capability.

I should add that this to me is an ideal way to run the system that I would like to see developed in time. I'm not trying to detract from the amazing work these guys have already done and are continuing to do.

Depending on price, and when if ever phantom gets a good kit to market I'll probably be building my own.

I won't piss on Phantom by putting out a parts list because they had a good idea and deserve to profit from it as long as they are quick about taking advantage of the current swell of interest. I will however say if your observant and know where to search its not that hard to figure out exactly what hardware they're using. The exact compressor wheel being used is the only thing I haven't, and probably won't be able to figure out.

28 is not much better.

Anyways, the supercharger sitting in the intake does not cause much restriction. I'd bet that the filter causes more restriction.

I just wanna figure out how to put 4 of these on my drag car. 8's with electric power adders would turn a few heads.

The intake system would look quite interesting, but 1 per cylinder would be epic.

These motors don't freewheel.

I was thinking what a WICKED deal this package is. Seriously. I've been dyno testing FRS/BRZ cars for free for guys to get a database of mods that work...

So the one below is a FA20 club intake, a SRT header back full exhaust, and a Visconti tune. I mean, what's that? like $2000 worth of stuff?

It didn't even break 170 on the same dyno, same operator, same load etc.... I didn't print the torque curve, but it's sad, like the stockers.

here is his sheet. The intake messed up the tune, so the "pinky" line is no tune, so fixing that somewhat the Visconti tune brought this back up to a decent power, and back to a smooth curve.

Although not completely comparable the black curve is a bone stock FRS, albeit with 5.0 or 5.10 rear gears(cant recall exactly), so slightly different load and accel rate. But a reference I printed at the time.

So what? A supercharger that's not spinning still has a giant gap for air to go through.

That's more than 2000 depending on when they bought. Visconti stage 1 is 850 I think and the header back is maybe 1200 plus the intake is at least 300.

Funny thing is my car made 168 stock on that dyno so I definitely think some funky stuff is going on with that intake. Exhaust actually makes decent mid range gains.

Going to get a track pipe for our next dyno session and see if that does anything. At least we will get better AFRs with that. Also will probably grab a K and N filter. Any restriction being removed pre supercharger helps out. Not that it would be much but km due for a change anyways
