I have a Mildly Modified 1999 GSR. Cams, pistons, PnP, I/H/E

The car used to get 27mpg city, 31mpg highway. Well last weekend I added a SUN Hyper Voltage System GT to my car. I already have there Hyper Ground System on the car. I got gas yesterday and checked my MPG, 32.4mpg, city. I hadn't even driven the car on the highway yet. I double check my math, right on.
I was expect a small improvement like 1-2mpg on the highway but nothing like this.

Another Note about the grounding wire on my cars.
I have these grouding wires on both my cars the 1999 GSR and a 1993 Del Sol Si. When I added wires to the Del Sol the highway mpg went up about 3mpg and the GSR went up about 2mpg.

Thanks for the ad.

HAHA.. this is the same company that sells the hot inazma pocket,
which claims to stabilize voltage, increase gas mileage, and create negative ions at the same time. right.

I'm also selling a kit that allows your car to run off ice cream with the only exhaust product being a combination of rainbows and bubbles.

mods, please smack this spammer.

 

Wasn't meant to be an ad. I was just sharing my experience with these products and how they worked for my car.
I was very surprised the increase I got, I was hoping someone else would also share their experience with similar results.
The voltage stabilization worked, a simple data logging on my S300 showed that, increase in millage showed that on my last fill up, dyno readings not yet.

Not sure about what this negative ion thing is.

I was hoping for more constructive comments but if all H-T has is "rainbows and bubbles" I guess I will have to take it.

He's been here for a couple of years, and I don't think his sole intention is to spam. It actually seems like he legitimately believes that these products improve fuel efficiency. I've always been an advocate of the ground (earthing) kits, so perhaps there is some sort of legitimacy to these claims. I'm not ready to penalise him just yet, but it would be wonderful if this could turn in to a technical discussion of the possible merits of supplying more stable voltage to the sensors and ECU.

 

My intention was to have a technical discussion about topic. I guess the Tech/Misc would have been a better location for this topic. Is there a way to move this post or should I just start over?

 

it would help if:

1. your subject line did not look EXACTLY like something in my junk mail folder.
2. you did not include a link to the manufacturer in your post.

also, 32.4mpg city? your readings are wrong. Although it is not uncommon for hondas to exceed their rated gas mileage, your car was rated at 25mpg city. You have a fairly modified setup too, so you are either hypermiling like crazy, not averaging your mileage, or something else, but you failed to mention specifics.

I must note that there is a lot of crap out there that will measure your mileage incorrectly.
On my '99 civic EX, my scanguage used to report a cruising 48-60mpg even when set correctly, just to give you an idea. And once i measured things i was actually getting an average of 34-37mpg.. on par with what the car was rated at.

So if you think i'm lashing out for no good reason, i hope you understand why.

 

may i also mention that this company ( sun ) sells a exhaust grounding kit that's supposed to 'reduce static electricity, lower exhaust noise, and increase torque response' ?

Sounds like a killer product. add some fuel line magnets, a vortex intake doodad, 18 fuel additives, some ebay crap, a hot inazma pocket, some faith healings, a 10 day cleanse, and donations to the church of scientology and you will be on your way to 70mpg city, easy. ;]

 

I remembered reading about it in a very old issue of Import tuner back when i really wanted some rice, lol. But adding good grounds does help fuel economy and hp.

http://importtuner.automotive.....html

They had some dyno charts in the original article, but anyhow, i didnt buy grounds I made em and dyno'd it with good results. Also helps get rid of some kinds of hesitation

 

Let's keep this discussion intelligent, and non-bashing, please. I've docked enough points today.

 

Agreed, grounding systems are actually good. They are usually best when you have cruddy old grounds in the first place though. My wires had black dirt on them.. they were *real* bad.

I also made my own, my '99 civic EX had a lot of low rpm bogging and such. Some semi-thick ( i used stock diameters ) wire with ring-shaped connectors crimped on did the job. I ended up changing my negative battery terminal, plus a nology wire for the trans/air filter area because i had some difficulty there.

didn't notice any mpg improvement though - the car got excellent mpg in the first place so i didn't really measure it's mileage at that point.

 

btw this is not a grounding system he's talking about. it's a mystery box you plug into your battery. It is probably a capacitor of some sort, if anything.

this company also sells those pills you put in your gas tank that are supposed to increase your efficiency by 10%. Multiple companies have been sued over these here in the US.

 

No hypermiling here. Just trips to gym and back home. Stop and go traffic, some stop lights and a 3 mile open stretch of road. No highway or cruise control.
I always fill up at the same station, full tank of gas, 93 octane. I reset the trip odometer every time. I normally shift between 5000-6000rpm.
148.5 miles, 4.578 gallons of gas, 32.4mpg

I can understand some what why your lashing out. I
was try to put this out there and see if anyone else had a similar experience with a Voltage Stabilizer.
My car did get 27mpg city before I added the Voltage Stabilizer.

Pills in gas, haven't look into it and not planning on it. Sounds like Snake Oil.

 

Dont know if you've already done this, but wait and see if your mileage increase is consistent. Every now and then i get spikes in my mileage without reason.

this where the discrepancies might lay. u fill the tank when its half full and not nearly empty. try it when empty and u might see theres no difference.

If i understand u correctly, i think that has nothing to do with it. For example: You can top off the tank, drive 5 miles and go top off the tank again, the math would still work out. Thats the beauty of math.

I think what more important here is consistency, given u have no dramatic changes in your typical driving style.

 

There was no change in my driving style. I am thinking it could be a spike but my car is very consistent. Since my last trip to the dyno for tuning, city has been 27mpg and highway 31mpg. I am planning on monitor this very closely over the next few tanks of gas.

That would be true if he were to estimate how many gallons he was putting into the tank by cutting the gallons his car holds in half when his tank reads half empty. The pump is telling him how many gallons he is putting in so he is doing it the right way, it does not matter if he goes about 1/4 of a tank of 3/4.

 

I think another good test would be to take off the wires after a little while and see if anything changes.
Im always a skeptic when it comes to this stuff too, but you cant trick the dyno right?

 

If you really want to increase you gas mileage cut a piece of 2x4 3 inches long and stick that [freak]er under your gas pedal Are you aware the gas stations change their fuel blends with the seasons, so even though you are filling up at the same pump you probaly are not getting the same fuel everytime?...sorry to rain on your parade, but the consitences you talk about are not obtainable on daily driven street car, now if you ran tank after tank after tank on a dyno keeping in mind your enviroment (humidity, ambient temp, etc) has to stay the same you would probaly discover there is no real difference. And your story might be believable if it was a few tenths more per mile, but a whole 5 on a car that gets 27 mpg....thats around a 20 PERCENT INCREASE, noway in hell is that even possible, if it was, the car manufacturers would be all over it, just to say their car gets this many more mpg from this new fancy technology...and as far as pills that increase your mpg, give me a break

Good point...

 

Tank #2.
274.6 miles, 9.424 gallons=29.1mpg city
This was mostly city about 10% highway. The highway was at 80mph with AC no cruise, was running late for work.
It was hotter and more humid this week so about 50-60% of this tank the AC was on.

So on two tanks now I have a City MPG average of 30.8mpg after the modification.
Man I need to find out what I can get on the highway.

 

I'm not really worried so much about mpg in my Integra, this just happened. I still drive exactly the same.

 

I think people forget that EPA estimated fuel economy is based on a fairly rigorous driving test.

People who drive like grandmas (aka my dad) will get considerably higher. People who drive everything like it's a get-away vehicle (like me) will get about EPA estimate, if not slightly less.

For example, my old 88 Prelude 2.0Si... with my dad driving it got 30-32mpg on a regular basis. I bought it from him, gave it a tuneup etc because he neglected it... and I couldn't break 28mpg to save my life (drove it daily for about 5 years).

Now with my 02 AP1, no matter how I drive mileage has pretty much always been 23-24mpg.... I hit 25.x one time and about died of shock.

As far as your voltage stabilizer experience - I'm all groovy with improving efficiency (in all systems... intake, exhaust, mechanical energy transfer, why not electrical too?) I didn't notice any mpg difference in upgrading ground wires, but headlights were brighter and car started more easily. There definitely could be something to providing a more stable current to sensors, so I'll give it a go on both cars and test your mpg theory.

 

Tank #3.
262.0 miles, 8.867 gallons=29.5mpg city
Now on three tanks I have a City MPG average of 30.2mpg after the modification.

Soon I'll post a bit more behind where the grounding wires are located and why.
