The Largest V8 Engine in Automotive History
The undisputed record holder for the largest production V8 engine in history is the Cadillac 500 cubic inch (8.2L) V8, introduced in the 1970 Cadillac Eldorado. This iconic powerhouse delivered 400 horsepower and 550 lb-ft of torque, embodying the golden age of American muscle with its massive cast-iron block and Rochester Quadrajet carburetor. Recently, we at Total Carbon Cleaner had the honor of restoring this legendary engine using our advanced decarbonization technology. Over decades, carbon deposits had muffled its true voice and stifled its performance—but after just one session with our machines, we unleashed its original soul. The difference is audibly transformative: in the accompanying video, you’ll hear the engine that echoes its 1970s glory. The smoother airflow, restored valve response, and optimized combustion now allow every cylinder to breathe freely, turning a historical artifact into a living symphony of power. This isn’t just cleaning—it’s resurrecting automotive history, where the growl of a 500 V8 once again stirs the soul of enthusiasts worldwide.

RADIO
Radio Interview of Mr. Aristogeitonas Kotsas, by the racing champion Mr. Stratos Fotinelis.
— And now we’ll move on to another topic, because many times, especially in recent years, you’ve seen engine decarbonization becoming fashionable. What does it mean to decarbonize an engine? The expert will tell us, because I have the pleasure and honor of hosting on the other end of the line Aris Kotsas, one of the people who knows the subject very well. We’re talking about Total Carbon Cleaner.
It’s a device for engine decarbonization, and now we’ll learn how many great things it can offer our car.
— Aris, good evening.
— Good evening, Mr. Stratos.
— Thank you very much for the interview, Aris, and I’d like you to inform us, since Total Carbon Cleaner is your specialty, what exactly this device can offer us in a car, whether gasoline or diesel?
— The process lasts 30 minutes for small vehicles up to an hour and a half for large trucks or heavy vehicles. We’ve even done it on tractors, to give you an example. What we basically do is restore the engine to its factory condition, removing pollutants, regaining the engine’s power. The driver, provided the car has no mechanical problems, gets a car as if it just came out of the dealership, in terms of emissions and performance.
— All this happens without mechanical intervention on the car, right? Meaning, in a simple way, I imagine, by the machine operator?
— Yes, yes, the method is very, very simple. In fact, the car is running during cleaning. At idle, we inject gas into the air intake, no need to touch a single screw. As a result, the hydrogen has the ability to magnetize the carbon deposits that trouble the engine. During combustion and discharge, it cleans them. Essentially, it turns these deposits into steam, and as a result, the car regains its breath and returns to its original state.
— You’ve done every kind of measurement, either yourselves or even customers who wanted to test you. You talk about dynamometers, emission measurements in five countries.
— Ah, I see. Serious work has been done, right?
— Yes. And what I wanted to say is that we’re now in the process of certifying a new model, which is used after cleaning the car’s engine, something that increases power – in small amounts, but it increases it – and minimizes pollutants. We have measurements in our hands right now showing over 80% reduction in pollutants.
— I understand.
— We’re currently in contact with universities to certify it and enter the European and global market.
— I imagine it cleans the valves, piston surfaces, cylinders, etc.
— Yes, the valve seats, also the DPF. We have measurements from DPF too, which surprises some people, naturally, but it’s true. Of course, we’re not talking about a damaged DPF, but when we talk about pollutants, we achieve restoration. Meaning, in practice, the whole process unclogs the DPF.
— Allow me to ask you something, Aris. This process, I imagine, must be expensive…
— It’s quite affordable, actually. Whoever does it gains…
— Meaning, how much can such a process cost?
— We have offers starting from 30 euros.
— From 30 euros? Meaning? All this happens for 30 euros? Unbelievable!
— Yes, it’s something we’ve studied a lot regarding pricing, with the aim of being economical. Because when an engine restores its pollutants, we too want to put our own stone and help Greece’s situation, which currently isn’t the best financially for every family.
— Right, and also be more environmentally friendly, because that’s very important too.
— Yes. That was one of the main things on my mind when I started the whole process: this and the issue of restoring the vehicles’ economy.
— Is this machine made by Greek hands?
— This machine is made by Greek hands.
— Bravo.
— I’m the one who designed it from scratch, without any copying. The idea came from various foreign companies, but right now our results are far ahead. For example, we have a dynamometer on a 2017 Clio – one of the most reliable, MAHA Petropoulos – where we achieved a 9.4% power increase on an engine in just 40 minutes of cleaning.
— What did you say now?
— The percentage is huge.
— Naturally.
— We’re not talking about 1-2%, which someone might consider a dynamometer error or anything else. We’re talking about 9.4%, which right now is the best anyone can show in the world in our field.
— In which locations in Athens and generally in Greece can someone find this machine?
— We have it in Vari, in Koropi – there’s a new partnership with Lamprido Koropi –, in Piraeus, in Chalandri, in Volos, in Kalamata serious work is being done, in Corinth, in Crete…
— It’s spread throughout Greece, right?
— Throughout Greece, yes, and we’re also looking for new partners.
— Can someone go to some web address and see, and contact Total Carbon Cleaner?
— Yes, of course. You can find us at TotalCarbonCleaner.com. It’s a website where we’ve covered all topics around carbon cleaning: the locations, the materials, customer testimonials. Also on Facebook under the title Total Carbon Cleaner, you can find the various partner locations. Anyone can go there to meet a partner, get any answer, and of course, to book an appointment.
— Aris, thank you very much. I wish you good luck and success in the rest of your work. Always a pioneer. Thank you very much.

Presentation at EPAL Kalloni and EPAS OAED
Students in touch with technological developments.
A demonstration of a Greek-made hydrogen machine for internal engine cleaning was carried out by Total Carbon Cleaner and Giannis Doudounis for students of the vehicle technology department at EPAL Kalloni and EPAS OAED Mytilene.
The demonstration took place instead of an educational trip for students, which are not permitted due to special pandemic measures, and was a first-class opportunity to familiarize themselves with technological developments in the field they will enter. Mr. Doudounis responded to the educators’ call, presented the machine of which he is the exclusive representative in the North Aegean, and answered all questions from students and their teachers. “This is a pioneering machine, 100% Greek-made, that competes worthily with other machines with a significant presence in the international market,” Mr. Doudounis told “Nea tis Lesvou”.
“Presentations like this help children see up close how technology has evolved in their field,” Professor Maki Evangelidis of EPAL Kalloni told us.
“Mr. Doudounis received many questions from the students and from us, but we were also given the opportunity to develop other topics around the curriculum,” he added, emphasizing how important such presentations are for students to see in practice everything they learn at school.
