Full throttle Electric Supercharger Build Thread

[Luckrider]

It is a shame that the numbers don't show the full glory of the Phantomcharger and how it transforms the powerband. There is a lot more gained than one realizes from just
the end numbers.

186 TQ at between 3,500 and 4000 rpm.

Fenton since I am bored I will warm the ride up and take a video just for you. Look for in the next hour or so.

Thanks all

1)What are the effects on the vehicle of engagement of the ESC below 2000rpm with a tune?
2)Is there any intelligence built into the dump battery charging circuit or is it a standard constant current transitioning into a constant voltage? Will LiFePO4 battery charging be supported at some point?
3)Will there be controller updates that might require sending the controller back to Phantom?
4)What method is used to determine the ESC motor position at the moment it is engaged? Does this induce starting latency?
5)What is the true latency from engagement of the ESC to full boost at different engine RPMs? Please quantify with numbers.
6)Will proportional boost(motor) control be supported by Phantom?
7)Assuming an infinite power supply, what is the duty cycle of the ESC motor?

Awesome thanks! Did you get a retune?

I feel like I still need more power. I think going from e85 back to 91 at the same time as installing the OFH and ESC has effected the overall impact I feel. I'm excited to go back to e85 and upgrade to a dual dump pack. In the meantime I'm going to do some comparisons with the ESC foot switch enabled/disabled.

Also as I have experienced and many others have when you first install the ecs and batteries you really have to give them some time to condition. Depending if they have sat for a long time they will need some deep cycles before they give out peak performance. Just keep hammering on it and you will be good to on no time. Wearing it down low with long pulls rather than short burst will help you get there quicker.

Only for you Fenton.

If you have time watch the entire video a couple of good pulls. Sorry for the shaky video and noise from the phone cradle. Also note the windows are down. Enjoy

That sounds really great!

This is with the ESC as well correct? Did you end up getting a retune?

1) Not sure if anyone has purposely gone WOT in a high gear @ sub 2K.
2) Charging is regulated for SLA's and has de-rate fail safes. Show me a LiFE stack that is commercially available and is suitable/cost effective.
3) Always will support my stuff
4) Sensorless. No hall effect required.
5) 250 to 750 ms ... depends on battery condition and if a DR pre-spools it
6) Perhaps, but much higher boost pressures will need to be achieved.
7) Duty cycle of the entire system is balanced, I have no infinite power supply, but the controller/ charger units fail safes trump the compressor motor.

I think FAQ's related to the present system would be beneficial ... as sub systems / revisions happen they will be added.

Fenton.
FAQ #1. Dump pack needs conditioning/ formatting ... ~ 4-6 hrs of total driving and cycling use. New batteries typically discharge @ 80% of capability.

Stock exhaust was 195 HP on your original dyno @Drift Office. Nice top end gain.

would it be safe to condition the batteries by sitting in the driveway with everything hooked up except the esc in hand, and then manually hitting the wot switch? I realize you would have to leave the factory intake pipe hooked up for this and have a friend to hold the esc or hit the switch. Then you could wait till it's fully charged, hold the switch till it's drained, then wait till it charges again and do it like 5, or 6 more times. Could you effectively condition the batteries in 10 minutes this way, or would you need a slower burn in or: quote "4-6 hrs of total driving and cycling use", to do it properly? I realize there would be no load on the esc, and this constant use could cause heat problems.

Ya im going to say just drive it. It would be a lot more fun. The load is what drains the batteries. Without significant load the batteries don't deplete very fast.

Plus the heat of the engine by gets the batteries to their sweet spot as well.

I am not sure there will be load on the compressor if it isn't being forced into the motor, but if there is sufficient load, it sounds like you want a battery conditioning mode on the controller which would be rather simply to design actually. Then you could just hook the batteries up to a trickle charger and them right at home overnight.

Hey just wondering everything else aside do you think the nameless headers were worth it over say the ofh? Not trying to start an argument just wanted to know your honest opinion.

Thanks

No doubt, both headers offer impressive performance. The advantage of the OFH is that it is paired with a tune for both the header and the ESC. That seems like a slam dunk...unless you were planning on going with another tuning option.
