How It All Began
Hello, my name is Jim Dimond and I'm the developer of a patent pending super high efficiency electric supercharger series. When I say "developer", it actually took several engineers from around the world to complete some parts, but I can definitely take a good portion of the design credit anyway. I can assure you that it is not an easy task to make a usable electric supercharger. Let me explain… Many years ago I had the same idea as probably a gazillion other people…hey, why don't I just put an electric fan of some kind on the intake of my car…that would surely work right? Yeah….it didn't take real long before I discovered it didn't matter if it was a fan in a tube(axial), round squirrel cage fan used as a boat vent fan or even a leaf blower…it is all pretty much an exercise in mutilating things that weren't intended to go on a car.
Weight Gainer Powder and Herbal Supplements
Then I saw a few companies come out with electric superchargers. It's one of those things that sounds great when you read the ad. You should feel an instant boost of power when that baby turns on, right? But, when you buy it and put it on…you might end up saying, "Yeah, I think it's fast, I mean, it seems like I felt a little something extra". It's like weight gainer powder and herbal supplements…it sounds great when you read the ad, something like, "gain super gigantic muscles with ripped abs and lose every bit of fat with all kinds of energy within 36 seconds of taking our product" or some such crazy claim…you buy it, take it and you say, "I think it might be, maybe, kind of feel like it might be working"…then you realize it was a bunch of junk and you just wanted it to work, so, for a moment you thought it might be. It is the same with many electric superchargers sold on the market today. I really like the idea of an electric supercharger...zero lag, no complex exhaust problems with turbos, no parasitic drag like belt driven superchargers. I thought...if I can have all that, it would be awesome. However, all the ones on the market, in my estimation, seemed to be a far cry from working how I wanted. You want to feel an immediate burst of power and not a, "it kind, sort'a feels like it works" feeling right? It
It Bothered Me
It bothered me that none of the electric superchargers on the market seemed to have the design and specs I was looking for...I knew it could be done. I want something to push me back into my seat when I wanted a hardcore launch. So, I said to myself the old saying; if you want something done right, you have to do it yourself…but, sometimes you don't realize how difficult something is to do until you go to do it. Likewise, it is no easy task to get an electric supercharger to work efficiently enough to produce at least some good usable psi. Oh' yeah, a word on psi…it takes both volume of air (CFM - cubic feet per minute) and pressure PSI (pounds per square inch) together in the right amount to make a usable electric supercharger. Don't let anybody fool you with claims that a high CFM number is all you need…it's not, that's why we have PSI gauges in turbocharged or supercharged cars and not CFM gauges. Anyway, back to what I was saying…here is what thousands and thousand of dollars, gobs of time and breaking a whole lot of supercharger stuff to find out what is ultra tough produced.
What would produce the specs I sought?
What Counts When Building a High Output Electric
Supercharger
Everything counts - Everything from the battery to the actual compressor wheel efficiency counts. Each time you add an extra element between the battery and the compressor wheel turning it takes away a little bit of energy that could be used more effectively. So, everything needs to be the best of the best or it just won't work. Cheap materials and components just won't cut it if you want to reach 80,000 rpm to 135,000 rpm…and especially when in the 200,000 rpm plus arena.
The Motors
Not just any electric motor will do. The vast majority of other electric superchargers that I've seen use what is called "brushed" motors. These motors have extra parts that, by design, rub on other parts in the motor to make it work…this means they can wear out extremely quick when you want to turn the rpm's that are required to build large psi…plus, that kind of friction and poor efficiency create a lot of heat after a very short time. Brushed motors just can't turn as fast as I needed with the long lasting toughness I needed…period. The answer, computer controlled multi phase motors. While definitely more expensive than cheap brushed electric motors, the performance is a whole world apart. They run much more efficiently, around 90% compared to brushed motors which can run around 70% +/- (or even lower in some cases). To get a motor that worked with the extreme efficiency that I needed, it had to have the required torque and able to turn at the super high speeds I needed - it was a tall order to fill. We ended up using hand wound, hand built motors. You read it right, these motors are hand built and tested. Remember, everything counts and the motor really counts! Our largest motors are about 5.30 hp each and our standard motors are about 3.30 hp each. Our smallest supercharger uses one single ultra high speed motor with about 3.3 hp (this motor is different than the standard 3.30 hp motors mentioned above, which require higher torque because they turn gears, the smaller unit is direct drive). All other superchargers use two motors. For two standard motors, that's 6.60 hp total and for our super motors the total is 10.60 hp for two motors. The SPC70 Aircrusher comes standard with the largest motors. For all others, the larger motors are an option. There are motors on the market that can produce a little more hp, but at far lower speeds…that just won't cut it for use on superchargers. It takes a fine balance of many different design elements to make this work with rock solid performance.
The Computerized Controller
Not just any motor control computer will cut it. Reliability under a wide range of conditions, low voltage/amperage capacity and poor vibration resistance ruled out many options for this. After a careful search of industrial computer control manufactures, we found one that would build them custom to our requirements. Too, moisture doesn't mix so well with intricate computers. This had to be addressed, so we developed a vibration resistant and moisture free computer case that also offered excellent cooling. This too, had to be custom made. Other elements needed were; it needed to be smart enough to make sure battery voltage didn't drop to low and affect your cars starting power, heat detection and turn off if needed to protect everything and speed braking to eliminate the need for a blow off valve. We found through extensive testing that mega high capacity computer system components, with extremely low resistance, were needed because of the extreme current draw in an instant of time to make these superchargers absolutely crush air into submission.
Mega Materials Needed
Exotic space age materials are the only way to go. Just like a highly advanced aircraft, every little tidbit of weight on any moving part is extremely important to make an electric supercharger work efficiently. Add to that, everything needs to be able to transfer heat well. Some parts have to withstand extreme torque in the blink of an eye…after all, our superchargers have zero lag! When it snaps to attention, you better have some hardcore great materials or you will have problems. Many light weight metals will simply tear and fly apart when turning at over 80,000rpm. You will receive a supercharger that uses titanium shafts, precision ceramic bearings, tool quality hardened steel and a very high end specialized aluminum that is 200% stronger than T6 grade. Overkill? Maybe, but hardcore performance materials are needed to get hardcore speed. There is just no other way in my estimation. I guess it boils down to what you want, do you want something iffy - or do you want to know you have top end components under your hood?
This is a biggie - Precision!
Precision, precision, precision, oh' and did I happen to mention precision? Without it, you could have pile of junk real fast at 80,000 rpm, and especially at 200,000+ rpm. Machining and bearings need to have extremely tight tolerances. Any kind of loose fit, even by a hair, will cause vibration, heat and loss of energy that could otherwise be used to turn the compressor wheel even faster. Precision is probably the most painstaking process. Some parts need to remain concentric down to 100,000th of an inch at minimum and we prefer accuracy measured by the millionths of an inch!
Smooth
It's gotta be slick! All of our superchargers come fully polished on the inside. Like I said in the beginning, everything counts. Especially when you are trying to accomplish a good psi reading. A highly polished air path truly affects performance. That only makes good sense, right?
Guts & Gears
The gears ended up being another real challenge. Ok, let me be a little more accurate...they where a huge challenge. Here is another area where you can really give away a lot of energy that could otherwise be used toward spinning the compressor wheel significantly faster. If you don't have the gearing and the gearing material just right...you may never get it work. Do you want to know the secret to the gearing? It's our patent pending Runsoft Constant Contact System. Each motor has composite twin star shaped staggered tooth gears that roll onto super high speed ceramic mini bearings located on a twin roller gear setup. Pictures can be seen on individual supercharger product pages. By using a twin star gear staggered formation, it ensures that there is constant contact between the motors power and the compressor wheel shaft. This translates to 99% efficiency of energy transfer...which is amazing. The entire power transmission gearing setup is extremely light and experiences almost no wear over it's lifetime...it is an amazing leap forward that makes the electric supercharger a reality.
The Compressor Wheel - Will It Float?
The compressor wheel has two parts to it. The inducer part that sucks in air and the exducer part rams the air into your engine with high force. Obviously then, this is an important part of the supercharger…especially when you are making an electric supercharger. This is because you may not have the same wattage available that an exhaust driven turbo or belt driven supercharger might have (turbochargers and belt driven superchargers have some big disadvantages when compared to an electric supercharger; we have a FAQ page on this). As a result, we developed our patent pending Hyper-Lite Compressor Wheel®, which represents another huge leap forward in making the electric supercharger a reality. These amazing wheels were amazingly hard to develop and even harder to develop a manufacturing process that would make them realistic to produce cost wise. Here is a neat little factoid about our composite compressor wheels...they are so light they float when place in water...try that with an aluminum or titanium compressor wheel and see what you get...so, as I'm sure you see - having a compressor wheel this light makes a huge difference. Most of our compressor wheels are around 70%+ lighter than there aluminum counterparts.
Keeping It Cool
Unlike many electric superchargers, we use ultra efficient motors that produce as little heat as possible. However, even if a motor is around 90% efficient, it will produce some heat. This bit of heat does not in anyway affect the air being forced into the engine like tube or axial superchargers. All models come with a liquid cooling system that includes a mini radiator, waters jacket for each motor, a specialized cooling system for the computers, mini radiator fan(s), pump, tubing, clamps and reservoir. This is a rather sophisticated cooling system. It uses a proprietary ceramic cooling system to keep the computers cool and a high flow design to keep the motors working with extreme efficiency. We have also developed ways to liquid cool the entire electric motor, including the copper windings by using special liquids…and not even short out the motors.
Electrical Power Supply
A high quality battery goes a long way. All of our units are designed to work from a good 12 volt battery. As a little note, we do not hook our superchargers to the alternator and the computer controller prevents the supercharger from making to significant of a draw on your battery's voltage. For the maximum speed and therefore maximum psi, 24 volts, or even 36 volts on large motor systems, creates the most psi. If you plan on running more than 12 volts, please let us know…you can run it one of two ways and your choice may require special electronics. When it comes to batteries, not all batteries are created equal. We offer some of the fastest discharge batteries with high capacity. Too, batteries come in a wide variety of sizes and weights. The lightest (and most expensive) battery we offer is made by Volt Phreaks…Their batteries only weigh between 4.5 to 6 pounds!!! If you have had to lift a car battery lately, you know that can save some real weight. Any good car battery make these babies turn at ultra speeds and the nice thing is that you can always add batteries for higher voltage or swap out to upgraded batteries at any time.
