Full throttle Electric Supercharger Build Thread

[Sojhinn]

Hmmm. I don't think mine is engaging. And Im pretty sure it was engaging before. I think I need to blow the tube again.

-Car off.
-Arm system.
-pull 1/8" tube off intake brass port.
- Simulate vacuum, suck on 1/8 tube, compressor will activate. blow to de-activate.

Not working.

Also note full throttle activation is working fine.

Tried every which way. Any ideas?

Something blocked in the hose?

Sorry I'm not sure what else unless the actual sensitivity needs to be raised in the controller itself. Rob should be able to walk you though it.

I have a question. All of this is based on a 24v or 28ah setup. would you be able to add additional voltage say bring it up to 36v?
Would that get you more rpm in the motor and thus a few more PSI?
I'm asking for future use. if I needed to make more boost with this system all in place. Or because the controller is 24v setup thats all you can run. I would have to change motor or compressor accordingly?

I'm not sure of all the specs of the phantom system, but most likey to operate at a higher voltage would require a different motor/controller/charger.

Also this system is pushing the limits of max RPM of these type of motors. As the motors get larger even though power goes up, max RPM generally goes down. One option would be to switch to a larger compressor with a larger motor turning at a lower RPM.

Looks like the sensor went out. Im just lucky that way. I think this sensor has been flaky since I had it. If you remember I had problems with it initially. Im going to keep the controller for the short term to knock out the tune and dyno, and then Im sending the controller back to Rob for a quick look and fix.

Ok. That's what I figured.
I had spoken to Thomas Knight the other day ( the guy that has successfully made a electric roots blower ) and he was telling me that he uses a larger compressor wheel modified for the housing so he can spin it at what the motor is capable so it may be 4x as large as what would normally be used but spinning 4x as slow as a typical turbo to get the pressure needed ( something like that. not actual true specs). I think having the electric drive with no lag issues and coming on so early in the rpm band throws away traditional needs to be conservative on wheels sizes. I wonder if a different wheel can be used in this system to get the extra air needed if so desired.
I also don't really know what I'm talking about, just really reading to learn and throwing ideas out there.

This is already a completely customized system to fully utilize the rpm the motor can output.

What you are talking about Rob has already done in this product. Its was engineered by him. Everything is custom built to his specs, the motor is reinforced to handle the extra load and speed, the control box built to scale out the kW as people always want more. His has been through countless designs (compressor wheel and compressor housing) to get where he is today.

Rob has spent years to get where he is today(many different platforms)....50 to 85 percent torque gain in the dip leveling to 25-35 percent gain at redline out of this system is amazing.

Fenton, I do wish you would stop exaggerating the whp/wtq gains achieved by the Phantom ESC. Where you claim 50-85% I see ~50% and where you claim 25-35% I see ~20%. I'm going by all of the dyno results that you've posted and I just can't find any that support your claims.

It's not like this is snake oil but by selling it like snake oil you introduce doubt. Well, IMO anyway.


Thanks in advance.

If fenton was the one selling this system, I could see your beef, but he's just the first test monkey. Excuse him for being excited by the system. He hasn't indicated that he is involved with the professional promotion of this system other than as a tester. Granted, there could be some shenanigans here and he is secretly Rob in disguise (anything is possible) but I highly doubt it.

I choose one chart, it was the graph showing 205.7 HP that is listed on the first page of the thread. There may be better or worse graphs...but I chose this one.

I charted the results below. Note, I chose 500 rpm increments, and there are better results between those intervals. But Fenton's claims are supported. For example the chart below shows a ESC torque at 4000 and 4500 at 182, but between those points the graph shows peek ESC torque of 184 while OEM torque at 4250 is 110...a 74 ft-lb increase or 67%. On this graph the gain is 50% to 69% in the torque dip and 24% at redline. Fenton's claim in the post above is "50 to 85 percent torque gain in the dip leveling to 25-35 percent gain at redline". The chart below supports a claim in this range. I'm sure there is a chart showing a 85% gain in the torque dip...but at this point it's on you to show me where I'm wrong.

My point, Fenton is being upfront with his data and his claims
