So, just who is this company, and who are these people doing all this work???

Jake Raby is an American Inventor, Entrepreneur  and engine builder. Jake has been responsible for major breakthroughs with a plethora of Porsche, and VW engines. Among his patented inventions are the IMS Solution, responsible for “saving” an entire generation of Porsche engines. Jake’s first business was Raby’s Aircooled Technology, and years later Jake has returned to his roots; being the sole designer, creator, and builder of all engines at Raby’s Aircooled Technology.

From Jake:

Raby Aircooled Technology is located in a small town in Northeast Georgia, named Cleveland. We are about an hour Northeast of Atlanta. Many people are familiar with the alpine village of Helen, Georgia; it is located in our same county and is just a few miles from our facility. Here we enjoy operating in my home town, and all the luxuries of small town life as well as the freedoms of it. Our facility is built on the property where I grew up, and one of our buildings is the same building where I built my very first engine for a paying customer, at age 13. In our entire county there are four traffic lights and until recently there were only two!

I could move our facility to California, gain a ton of customers and be like everyone else. I won’t do this because I love where we are located, and I have worked on this same property all my life. I get totally engulfed in my “Zone” as some call it. I believe that focus makes the difference. Make sure to read about our shop on these pages as well, it has a rich history behind it. I often feel sorry for Archaeologist a few thousand years from now because the entire property is pretty much littered from “VW Remains” from the last 3 decades of my playing with Porsche, and VW engines.

Today the engines I build are created just like they were 25 years ago. Each is built one at a time, and without the constraints of calendars, or clocks. Neither of these will be found in my work areas. I focus on the creation of a single engine at a time, and give 200% of my life to the purchaser of this engine for the duration of time required to achieve a positive result. I refuse to compromise quality for quantity.

We are not a mass producer of engines and we are not located on the west coast. Here it takes as long as it takes and is done to the best of our ability. The average wait time for my engine to be delivered is one- year from the time the order is taken, and the initial payment is collected. At times, this can be even longer; so plan well in advance. Please never ask me to rush… Jake Raby

I am the boss, the machinist, the balance technician, and the guy that dreams up the combinations and finds the odd parts. I don’t do all this work myself, but I do have an excellent staff that I trust to do the job as well or better than I can personally. Just like any business owner, I get here before everyone else and I leave here several hours after the last employee walks out the door.

Engine Building Theory


 Most companies in the aircooled engine business build a higher volume of engines in a month or even a week than we do in a complete year. The average amount of engines that we complete per year is a whopping TWENTY FIVE!

Each engine is custom built for its application, it’s built for the driver, and it’s built for your car in your climate.  The reason for this is to assure that the engine will retain a long life, while having peak power at a very usable power range, good economy and low maintenance. We build for efficiency as all our testing has proven that all good things follow it directly.  The Aircooled Technology division of RabyEngine Development is a strictly aircooled establishment that caters to every breed of enthusiast that loves the VW or Porsche. This includes those hardcore SCCA Porsche racers, right down to the little old lady with a 36HP Type I in her beetle that she bought new in 1956. If you want to know more about why you should choose us for your engine project be sure to look at “Why choose RAT” from the menu.

Our VENOM PERFORMANCE (Type 1 based engines) division has now been abandoned as we have chosen since 2003 to only concentrate on the VW Type 4, Porsche 356 and Porsche 911 engines. We cut our teeth on type I engines and haven’t forgotten them! We just got tired of consistently sub-standard parts and continual assembly issues due to a total lack of industry wide quality control. We don’t have the time and need more variety in our lives than the regular old routine that all the other guys do.

Aircooled Technology specializes in making dreams come true.  Everyone dreams of big power, low maintenance and reliability.  These are not dreams, we make them reality.  The “big block” engine used by VW and Porsche can be outfitted for use in your Type 1, Type 2 or any other vintage jake raby VW or Porsche.   Raby’s Aircooled Technology has set the standard in Type 4 power and conversions and has led the way with recent developments that make these engines the “Modern Aircooled Alternative”. If you want Modern power, (180HP of it+) and want it with the possibility of Air Conditioning that you can run while you cruise 85+ MPH for sometimes as long as 100K miles then you have chosen the right company to build your dream engine.


We do the job right or not at all…

Aircooled Technology specializes in bringing back to life all 4 cylinder Porsches and Volkswagens from  Type 1 VW conversions to 4 Cam Carreras to 356 and 912 engines and even the 911 six cylinder through the 993 series.

In summary; if your aspiration is a correctly assembled engine, using correct parts, modern advancements and ready to drop into your VW or Porsche Vintage vehicle you are our kind of customer.  We do not believe in short cuts or poor workmanship; we take our time so do yourself a favor and don’t rush us.  Each job takes as long as it takes, customers that are in a hurry should seek another creator for their dream engine.

We hope you will cruise through our site and book mark it.  We will constantly be adding new and exciting pictures and stories of our ongoing projects. Be sure to look at our individual biography pages here and our personal vehicles. Our business is owned by an enthusiast and our entire staff is enthusiast based, we love VWs and Porsches, too, just like you. Working with them everyday brings us more pleasure than the paycheck that comes with it, and for me it’s a childhood dream come true.
