electric opel GT

im looking to build an electric car soon, and im considering the opel GT for this conversion because its larger than the other car i was considering, much cooler, better looking, and theres a ton more after market for it.. was wondering if anyones ever done anything like this to an opel? i will most likely be using an 18hp continuous (like 60hp in burts) which in an electric car is comparible to 3x that amount in HP in a gasoline car... in a single shafted motor which will connect to a driveshaft and drive the rear differential...

Me too! But I wouldn't want to do it to a GT.
I want to start with a fairly late model Volvo wagon. Something that isn't too old or rotten or collectible. And safe to be in.
Unless GM gets going on the Volt. I'll take the first one. Might be a while yet, apparently.
A site I recommend is www.EV-America.com

No Opels were harmed in the filming of this movie.
However two Mustangs, a Pinto, and a Capri were hospitalized.
One Mustang was euthanized the next morning.

wow.. well, royce chows electric opel is of the exact specs of what i was thinking.. i was considering using 12 12v batteries at 144 voltage with about the same power motor, i was hoping for about an 80mph top end and 50 mile range with 12v batteries, which in all my typical daily driving, ive never traveled further than that a day, except for once in a while which is why im thinking of getting the small biodiesel generator till lithium batteries are cheap enough and i could get that 250 mile range...

to whoever said they were thinking of a newer volvo, i know what you mean, im still not 100% decided on the car (ive considered an older benz convertible, the BMW E30, even the more recent smart roadster... but for the price, and styling, the opel GT is certainly the best looking thing i can find at a very low price.. though someday i wouldnt mind a GT with a 3.2L BMW I6 in it... but im trying to distance myself as much as i can on dependancies of any sort.. and dependancy on a rather volitile fuel market is a top priority

Justin, Here is a link to an Opel conversion on YouTube. It's pretty long...and boring.

Good luck, It sounds great. I think I'll convert mine to burn alcohol.

Has any one done any research into HHO? I have and it's quite interesting. I talked to a civilian we have over here to help us and he runs it back home. He claims a 10MPG increase and he just got started with that conversion. He bought the stuff at Home Depot to make it for $40. I'm gonna look into this when I get back to the states.

What is HHO is this the hydrogen generator to suplement the gas? my initial look thought that not enough hydrogen could be generated. if thats what we are talking about. whats a weber flow 300cfm, thats quite a bit.

Yeah HHO is Hydrogen Hydrogen Oxygen. You split water into it's basic elements and burn it. From what I've read we have come a long ways at how fast we can split it and how much we can make. The Army signed a contract with one inventer to produce a water/diesel HMMWV. It won't replace the use of Gas, but it does increase gas mileage and HP from what I've been reading. I'm just saying that it is worth looking into if your looking to go "Green".

i've always had my doubts about the hydrogen generators that seem so popular with the rise in gas this year. One thing that really make s me wonder abiout the credibility of their claims is why are these system eiether backyard engineered, or made by an unknown company? Why don't any well established name brand company offer complete kits?

Also, check out a couple of other views on the subject and decide for yourself: Scientific proof proving that HHO scams are a fraud

Those are all good sites with good science attached to their theses, but do either of them take into account the amount of efficiency improvement gained from just adding a little water into the fuel mix? Adding water raises the ignition point of the fuel, which should allow a higher compression to be used. It also does a really good job of capturing more of the heat energy for use - when the combustion turns the water to steam, the added volume of the steam helps to drive the piston. Additionally, I remember reading somewhere that water helps the propagation of the wave front in the cylinder, allowing for a more efficient burn.

Now, as I stand back up so as to not be talking out of my ass anymore, I'll admit that I'm not very qualified to speak of these things, and am in fact just remembering things I've read. Help anyone?

I found a good site better expaining this:
Linky
My thesis being that the improvements they are seeing in HHO vehicles are real, but not because of the reasons that they think.

I'm 100% with you on that!!

A few months ago I raised my average weekly in-town fuel economy in my Focus from 24 MPG to 32 simply by intentionally changing my driving habits. If I would have installed one of these kits at the same time I focused on altering my driving style, I'd probably be claiming the HHO kit provided the 8 MPG improvement.

I would not add water to the gas especially with fuel injection. Its your #1 enemy. Infact I actively add alchol to the gas on the motercycle to get rid of the water. as for the hydrogen it takes more then 12v to seperate it from the water. they claim you can add a catylist to get it to seperate but then you have to figure in the cost of that. the thing to think of is not MPG but the cost per Mile to run for me the cost per mile for my 25 mpg car is alot less then the cost per mile of a Prius which is supposed to get 45 or more?

do the math it may be cheaper to drive the lower Mpg car

and yes I can get about 4 to 8 mpg better by a few more lbs of air in the tires an driving style

I grabbed some scraps we had out in the bay, just to see if I could build one. It took me about 10 min. Now I wouldn't have installed that on my car or anything I just wanted to see if the electralosis would split the water off a 12V battery,it did.
Oh and there is no Catalyst invovled in the prcess. You do need an electrolite to conduct the electricity. They were reccommending 2 TBS Baking Soda to a gallon of water. How much would that add in costs? I was looking into how long water lasts and I read that if you drove an average of 2000 miles a month a gallon would last you around 8 months.
Opelnut_1 you don't add water to your fuel. Water is made up of two types of atoms. Oxygen, which is an oxidizer which is needed to combustion and allows any fuel to burn. Hydrogen is a flamable gas used by NASA to launch space shuttles into space. The individuel elements themselves are harmless to engines.
Now what is NOS? Nitrous Oxyide is a oxidizer, it is a non-flammable gas that allows a more complete burn which increases horse power. The average car only burns 30% of the fuel. the other 70% gets blown out the exhaust. If you add an oxidizer you get a more complete burn and don't waste as much gas.
So with that, how would adding extra oxygen and hydrogen to a car hurt anything. Heck even if you only recieved a 1-2 MPG increase, you would pay for the HHO unit in no time. The guy over here I started telling you about isn't selling anything, he is just using it and told me what increase he received.

Bull. Do not waste your money, effort, or time on installing a HHO system on your car.

There is no such thing as a “free lunch”. In science it is called the second law of thermodynamics. If there was any weight or truth to the claims made by the people pushing HHO then everyone would be using it… but the simple fact is that very few people use this idea and no one has been able to produce the claimed results in a laboratory.

It takes energy to break water down via electrolysis. More energy in fact than you’d be able to extract from burning it and returning it back to water. Efficiency and fuel economy decrease because of the added drag on the engine from the alternator constantly pulling and a lack of return on that “work”.

Who told you that your car only burns 30% of its fuel? Liquid hydrogen is used as a rocket fuel because of its favorable specific impulse (ie it generates better thrust than most other rocket fuels). This has nothing to do with its suitability as a fuel in an ICE.

NOS is an oxide. Basically that means you are injecting more oxygen into the engine so more fuel can be added at the same time so more useful work can be produced by the engine for a given displacement. HHO and NOS are nothing alike. HHO takes energy from the engine that could otherwise be used to move the car and uses it to break down water. NOS on the other hand is stored on board in a limited amount, so the engine is having to take none of its own power to “generate” NOS on the fly, so when it is injected with the correct amount of fuel it results in an increase of output. The basic idea is that it increases volumetric efficiency. If the hydrogen and oxygen were separated outside of the cars engine (ie your house) then it could be injected into the engine to have some benefit BUT storing pure oxygen and hydrogen in your car is a significant hazard. Ever hear about the old smoking ladies on oxygen who blow themselves up? Oxides are what kill careless scientists.

Also on the idea that HHO somehow gets you an increase in MPG via the water delivered to the engine after the H2 and O react to form water is also bull. Water adds no additional energy to the system. What it does is effectively increases the octane rating and absorbs some of the excess heat that would otherwise be dealt with via the cooling system. Now with the last statement you’d think it would increase efficiency but in practice water quenches the combustion process. This means that there will always be some hydrocarbons that were not consumed by the combustion process when you inject water into the cylinder before combustion. If water is injected after the combustion process is complete then you can get a slight increase in efficiency because the water is able to extract more useful work out of the heat produced via the steam taking up significantly more space than water. HOWEVER HHO cannot be injected after the combustion process to get this benefit.

Unless you the type that believes someone really has a 300mpg magic carb don't waste your money on a HHO system.

------------------

Back to the topic at hand.

Are you wanting to convert a GT to electric because of fuel costs or is it just that you want an electric vehicle? If costs are a major consideration I've yet to see any electric vehicle conversion that didn't have a significant pay back time. General rule of thumb in business is that if the payback period is less than 12 months it is a no brainer to do... however if your payback period is 3, 5, 10 years (etc) then you also need to factor in expected repair costs into the mix. Also consider that if it takes 5 - 10 years to payback the cost that it may be exceeding the expected useful lifetime of some of the parts (potentially batteries as an example). If that is the case then it would have been cheaper to pay the gas over time than pay the money up front and lose a significant amount of working capital on a hedge that it might be worth it in half of a decade. You have to consider that 10000 spent today is about 14000 in 7 years. That is 4k of lost potential earnings from that money. Just some food for thought! If you decide to undertake the conversion I wish you the best of luck in a trouble free swap.

Okay Gumby, I think that you might need to go back and refresh your chemistry a bit. Oxygen is an oxidizer, it is a non flamable gas. You can put a flame to oxygen all day and nothing will ever happen. What oxygen does is it makes things burmn more effectively. Things that normally won't burn, will with oxygen. That old ladies who smoke on oxygen thing, they don't blow up. the added oxygen in the air causes things to burn much more easily, things like funiture flare up in no time and they burn to death.

Now your statement about the added drag on the altinator. Sorry but do you understand how a altinator creates energy? Your engine spins a series of magnets across wires which coat the inside casing of your altinator. you can take a wire and a fridge magnet and create energy by rubbing the magnet over the wire with out touching the wire.The magnets don't touch anything and cause no more drag than the altinator bearings. If you have a 60 amp altinator, and only draw 10 amps out of it you will get the same drag as if you draw 60 amps out of it. I know it has been a while since I was taught about altinators in AIT, but I confirmed this with our maintenance techs.

You are only partially correct on the NOS. There are different types of NOS. You have a Wet and a Dry. Both increase horse power. A dry sprays NO2 into the intake and it is sucked in to the engine which helps the basic fuel load burn. A wet system increases the fuel and injects the NOS directly into the cylinders which then supplies extra fuel and gives an even greater horse power increase over the dry system.

And finally you mention that adding water to your engine can actually cause it to run less efficant. You are sort of right, but I'm not talking about using water to cause your engine to run. I'm talking about using the basic atoms. Water in itself, your right. But through electralosis the water molecules are split and what your car uses is it's basic elements. You can take Hydrogen and oxygen and combine them in a container and you don't get water the atoms have to be combined on a melecular level. Now can you dispute that Hydrogen burns? No just look at the Hindenburg, or the space shuttles. And can you dispute that oxygen helps a fuel burn better? No look at Oxy Acetylene. Acetylene burns by iteself, you add oxygen and it suddenly gets hot enough to cut steel. There for if you increase the oxygen and extra fuel (the H2) you would get an increase in HP and therefore use less fuel.

Don't be afraid of trying new uses of technology. At one point the gas powered engine was new and every one looked down on it over the horse drawn buggy. At one time we thought anyone making a flying machine was crazy. And at one time we thought that alternative fuel cars were crazy, yet now there are thousands of them driving the country.

You know why companies aren't building the systems? No profit. Where is the profit when anyone can make a system like this in their garage? Where is the profits to the oil industries? You know what? My first car was a Ford EXP with a 2.4L carberated engine. I drove that car hard as hell and I still got 44 MPG. Now if we can make a car that gets 44MPG in 1983 why is it that 25 years later, to do that you need to pay an extra $10,000 for a Hybrid? People in our country, maybe not you but people in general, have lost their ability to think for themselves they believe whatever they tell us on the news. They don't think for thenselves. We are a nation of followers that suffer from ADD.

Where's the profit? In lazy assed people who would rather buy a fancy looking piece of equipment rather than build it themselves.

This is absolutely, positively false. Due to the increased field strength required to make more current increasing load on an alternator absolutely does cause more load on an engine. Anyone who'se ever hooked up a set of jumper cables to a dead car can confirm that and your tech friends are positively incorrect.

You are only partially correct on the NOS. There are different types of NOS. You have a Wet and a Dry. Both increase horse power. A dry sprays NO2 into the intake and it is sucked in to the engine which helps the basic fuel load burn. A wet system increases the fuel and injects the NOS directly into the cylinders which then supplies extra fuel and gives an even greater horse power increase over the dry system.

A dry NOS system only works on a fuel injected car, and there only because the oxygen sensor detects the extra oxygen in the end result gasses of combustion and adjusts the fuel supply to make up for the difference. The only reason a wet system would make any more power is if the EFI system was unable to compensate for the additional oxygen due to injector or controller duty cycle or internal programming. Wet systems are the only way to go on systems that try to add more hp than the stock injectors are capable of or in non-EFI systems.

And finally you mention that adding water to your engine can actually cause it to run less efficant. You are sort of right, but I'm not talking about using water to cause your engine to run. I'm talking about using the basic atoms. Water in itself, your right. But through electralosis the water molecules are split and what your car uses is it's basic elements.

Having been trained and operated the most efficient electrolysis system currently being built in industry, the one used by the newest of the nuclear class of submarines and the the space shuttle, I can tell you positively that the combination of hydrogen and oxygen produces energy and that in order to split them up you must apply energy to the system. In chemistry those processes are called exothermic or endothermic. No one disputes that water can be slpit into it's component parts with enough applied power, the thing that makes it into snake oil for a car is the scale. Since the burning of hydrogen and oxygen produces energy, and it's a molecular process that's easily repeatable and measurable, we can easily find out how much energy it produces. That amount of energy is on the order of single-digit percentages of the amount of power produced by the combustion of a fuel atom simply because a hydrocarbon fuel atom may have a dozen or more hydrogen atoms that get oxydized. That means that in order to achieve a comprable amount of power from a given engine as it produced on fuel, the air flow requirements would have to be substantially increased over current air flow requirements with gas. In real world terms of scale, that oxygen bottle in the oxy/acel setup and (two of them of hydrogen) would be consumed by the motor in mere minutes. None of the HHO or brown gas generators produce hydrogen and oxygen at even a tenth of a percent
