Hi all, I have a question that need gurus out there to help decode.

I came across someone selling a homemade voltage stabilizer with 100000 uf worth of capacitors, with emphasis on good grounding wires for certain components in the engine as well. I wonder does it really help in the operation of a car electrical circuit and boosting its performance?

In fact, I wanted to buy it form this guy but he is no where to be found. I guess I would need to DIY it myself.

Please refer to the 2 links for more info:-

Could you please help to enlighten me on this.

Thank you!

 

Horse shite, or as you Americans say Snake oil.!

All you're doing is improving the return earth path.

 

Those capacitors are typically used for those with multi-kilowatt boom boxes in their vehicle.

What part of the electrical system are you trying to boost the performance of?
Everything is a car's electrical system is designed to operate properly with the system as it is.

 

Reminds me of a review of an exhaust system in Bike magazine (many years ago). In the next issue they published a letter from a reader proclaiming how fabulous this new exhaust was. He said that the engine RPM at 60 MPH had reduced from 5000 to 4000.
Magazine comment "First time I've known an exhaust system to change the gear ratio".

Save your money for something that will actually give you some return on your investment - this isn't it.

Use common sense. If something sounds too good to be true, it probably is.

Educate yourself. Fools are too easily separated from their money. Don't be one of them.

Some places are offering 1 Farad capacitors for that - the prices are unreal.............

 

the prices are unreal.

Yes, but getting the oxygen out of the copper is a very labour intensive process

At least that's what they tell the audiophools..................

Years ago I saw adverts for square loudspeaker drive units that were allegedly designed for digital audio - their price tag was also a lot more impressive than the performance.

 

designed for digital audio

Ah, my audio system must be digital. It has an on/off switch marked with '1' and '0' .

And I've been getting digital quality on my analog TV for years. I can tell by the missing squares in the picture.

Going down the list of claims, playing Devil's Advocate on each one... Meh, ok, whatever, fine, WTF? had to come back to this one...

Reduce sudden car slow down when you rev and at the same time Air Cond compressor pumping.

WOW, that is amazing. It is providing some mechanical advantage, like an extra heavy flywheel.
Must be turning the alternator into a motor to offset the brief change in mechanical load when the A/C clutch kicks in and bogs down the engine RPM.
I'll be ordering one right away. Where do I send my money? HAHA.

159 pages of replies to the thread. I wonder how many accounts he has on that forum? ...and if he ever get tired of talking to himself and patting his own back.

Actually spent a few minutes reading through some of the comments on those 159 pages. If he is manufacturing his own reviews, he is going to extremely impressive lengths to do it. A lot of positive reviews from people with hundreds and even thousands of posts. In fact I was scanning page after page for a bad ("real") review and did not find one.

I think there may be some benefit to installing a capacitor bank in a car; as I said, I was playing Devil's advocate, not willing to write it off entirely. but the claims sound exaggerated. The people buying and reviewing the device may be "true believers" .... people who buy snake oil and then convince themselves that it works. They may be seeing some improvement in some area and then extrapolating to cover all areas.

Or maybe the damned thing actually works. I don't know. I can see some of the claims as plausible, but all of them? especially all of them together? It sounds too good to be true, which usually means it's not true.

I think a lot of the improvements described can be credited to the improved grounding that the seller recommends when installing the device.

 

I was particularly impressed by this advantage of the VS, per one of the reviews :-
"Air-con is colder at same temperature" .

 

The unfortunate reality is that in many vehicles keeping the electrical systems clean of noise is very low priority in their design so adding the proper types of capacitors and values of capacitance in the right places can in fact clean up false triggering events coming from or interfering with various sensors and control components signals.

I have driven and worked on Fords all my life and I can say that from first hand experience of dealing with their electrical oddities that if they were in charge public water supply filtering they would consider a piece of chain link security fence stretched across an intake pipe that draws water out of a muddy river good enough filtering.

So does that guys design have merit? Well maybe just a little if used on a vehicle wit a ridiculously bad electrical system noise issues. However as the reviews read I have to suspect that he and a number of his online buddies, who have a financially vested interest have far more to do with the over the top postive reviews than any real people do except for the idiots who will never admit they bought a scam device and got taken or that they suffer from extreme placebo effect perception issues.

I'd say an impressive amount of false advertizing and a load of halfwits who don't know a damn thing about how their vehicle works has more to do with the reviews than anything. There are a lot of crooked and stupid people in the world today.

 

Ok, sum are correct....thats only for vehicles with large amps and subwoofers. As for the actual vehicles electrical system ......many people don't know this unless they've tuned an ecu......your f.i. vehicles computers run off of preset maps. The voltage has a lot to do with your fuel injector latency offset. So more less it's used wen cranking to start the engine, wen alternator isn't charging. And wen it is running. So unless your dimming your lights wit hella beats.....theres no point......drop mike here......hehe

Bit of a new language on this site, but I can pretty much understand you.
Can you slow down on that F.I. latency tell a little more?

 

My van has 200k miles on it and no capacitor bank. If/when it dies it won't be for lack of one. What exactly would justify the cost of it?

 

It's just the timing wen the injector opens and closes. It's dependent on system voltage. Less equals sooner, more equals later. Higher voltage runs faster then lower because of the nanoseconds it takes to perform correctly. Don't waste money on capacitors unless your tieing into an amplifier for a subwoofer. Lol.

That's probably all true, but the people that designed it did so with the electrical system as it is and not with a steadier voltage. It does not follow that changing the electrical system post-design will be guaranteed to give an improvement, since the designers will not have anticipated this change. Systems are designed as systems and even an "upgrade" to part of a system can have unintended consequences.
