Full throttle Electric Supercharger Build Thread

[jamesm]

this seems like an excellent opportunity for an open source project. i'll donate time to the microcontroller programming and solid modeling/fea/machine work. i already have a turbo, but it'd be good for the community to get together and build something awesome. i'll even stand up the website/repo/forum to collaborate on. who's in?

It's already getting to a point where it's annoying to keep reading about how awesome it is without any real development updates directly from the manufacturer or information regarding when others will be able to purchase this kit for themselves.

It would also be really nice to get some of our questions answered directly by a Phantom rep. I know I'm not alone on this.

Robftss is the man behind the tech, and he's been posting. By all means, ask him directly any questions you have.

Thanks, wasn't aware of his role!


@Robftss , can you address these questions please?

Some of us have been asking for an update that will allow safely running it without a tune, as that would be a true bolt on, removable without a trace for the dealership, installation.
I think (okay, hope) he is looking into the best way to do that.
Plus there are the hordes of power mongers clamoring for more boost on the upper end.
There is a little more work for this to be ready for prime time.
www.phantomsuperchargers.com if you want to see some of his other kits and get a feel for pricing.

[fenton]

Rob has told me that this is going out to i think 4 forum members that have contacted him through the website. phantomsuperchargers.com

Interested applicants can contact him though there but if you want the product now you have to understand the limitations ie. the system is not going to make 5psi at redline.

Ive only had this on my car for about 2 weeks so he is looking for more data before he gets this going full speed.

Thanks,

Very good results on Fenton's FR-S, arms length feedback on his and others who have tried it determines the final product.

Variable control devices have been modelled to simulate conventional induction, conventional induction is variable by its nature because its relationship to its power source, attempts are being made to stay 'off boost' as long as possible and only use it to raise the base engine's ability when needed. This provides better economy and longevity, in other words trying to simulate a WOT condition.

Presently, the partial activation provides better than stock intake (~6-8 "WC) and adds a little power and excellent tip in responds where needed. The onset of boost is deployed not to overwhelm the base engine and is applied smoothly, it is simple and very effective.

As far as stock tune, Fenton drove around for a week being mindfull below 3K. Since this is activated with a simple throttle switch any number of 'window switches' can be used, even ones that activate a rev limiter tach light, cheap and effective. Providing a calibrated or user adjustable manifold referenced/ tach signal compressor rpm ramp up for the 1500 to 3000 range is better spent on the edits to the ECU that we'll have.

I am thinking of a selector switch where one can chose ~40 ftlb/20hp or 50ftlb/35hp(with tune). That's easy.

More to come. I'm thinking of getting one of these cars, the FA20 is a work of art!

Rob, thanks for posting. I didn't realize you were reping the company, glad to have you in the community.

How many deep cycles are the batteries capable?

Is the controller capable to recharging more then two batteries? (I know the alternator also needs to be able to supply the current, I'm just asking about the controller.

Any thoughts on the flow rate that could be achieved with a 36 volt system?

[mid_life_crisis]

Some of us have the right background to be interested in experimenting with making our own controllers. Can you tell us what motor is used on these so we can do some research?

[autobrz]

This is the ideal system for me as I drive 100% on the street and will have plenty of time to recharge the batteries between WOT runs due to speed limits on the streets. I'm very interested to see how partial throttle control develops and how many "steps" are provided between 0% throttle and WOT.

[mid_life_crisis]

It doesn't look like there will be "steps". There are three states: off, full out, and running just fast enough to keep from becoming a restriction in the intake path. Fortunately the third state appears to have the added bonus of providing a slight amount of pressure pretty much at all times, which provides a noticeable improvement in throttle response.

What people really need to know is that this is just like the car you own today except when you want more power there is more power.

I want to reiterate that you don't step on the throttle and jet engine starts behind you at full thrust causing a "rough" ride.

Its a FRS and when you go WOT it turns into a big V6 instead of a small 4 cylinder.

It is very very smooth, nobody would think anything different driving with you in the car, once you go WOT it is a nice surge of torque

fenton what's next with this kit?

I've already started sourcing parts to build my own. If enough of us are interested in doing an open source version perhaps we should start a separate thread.

My only concern would be people without the proper expertise trying to build one and causing harm to their car or worse themselves.

I've driven it and can say that this is a very accurate description.
Don't need to wait til high rpms for acceleration either, it just goes and it's not a sudden surge.
