Orville Wright Hello, my name is Jim Dimond and I'm the developer of a patent pending SPC high efficiency electric supercharger series.  I feel the first thing that I need to mention is, that, most won’t qualify for this type of high end product...and for others, they won’t even have the intellect to understand how significant this is.  For those people, they would probably do well to just move on to other shiny object for engines. 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 kinda, sort'a feels like it works" feeling right? What’s On the Market 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 Makes the Difference? 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 150,000+ rpm plus arena. What Motor Could Deliver? 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 very expensive, especially compared to 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 once they get hot).  To get a motor that worked with the extreme efficiency that I needed, it had to have the required torque and be able to turn at the super high speeds I needed - it was a tall order to fill. We ended up using expensive hand wound, custom fabricated, specialty motors.  You read it right, these motors are hand built and individually tested. Remember, everything counts and the motor really counts! The next consideration was voltage.  We needed an effective higher voltage motor and a way to produce the high voltage to power the motors.  As a result, we now use custom high end 42 volt motors, each being about 4.7hp.  Why is higher voltage better?  It takes less amperage and gets to higher speeds with more torque than a 12 volt motor.  Our triple motor setup is 14.1hp and our quad motor setup is 18.8hp total!  Using the new AirCrusher-HV requires using a matched Thunderhead 42 volt alternator to power the supercharger.  It takes a fine balance of many different design elements to make this work with rock solid performance. You Can’t Have One Without the Other Even a high output 12 volt alternator of 300amps+ won’t produce the needed power for sustained supercharger use.  As a result, we created a revolutionary new patent pending high voltage 42 volt alternator and a dual voltage 42v/12v alternator.  Again, this was no easy task and took years to develop and is costly to build.  For our no holds barred customers, it’s one of the most desirable features.  It had to be compact, much more efficient than stock alternators, liquid cooled and produce huge power.  Our Thunderhead alternators are over 90% efficient and have astounding outputs of up to an equivalent of 23hp+.  We also use an outboard rectifier setup to ensure a long life.  Like our superchargers, we use specialized ceramic bearings and secondary processes to metals for superior operation.  The 42v/12v version is aimed at replacing stock alternators and the 42v version is a simple ad on to your belt system.  The 42v version comes in either a 3” diameter long body or shorter 6” diameter body. Built to keep Going and Going and... 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 grade materials or you will have problems.  Many light weight metals will simply tear and fly apart when turning at over 80,000rpm.  From us, 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?  Not for our customers.  They demand high end materials for a high end build.  There is just no other way.  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? Precision At SPC, we are all about 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 120,000+ 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! The Secret is Inside! The gears ended up being another real challenge.  OK, let me be a little more accurate...they were 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 patented RCCS® Power Transmission.  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.  By using a twin star gear in 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 set-up gearing 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 today. Cool Under Pressure Our high end, high cost motors are around 90% efficient.  So, 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, water jackets for each motor, a specialized cooling system for the computers, mini radiator fan(s), a pump, tubing, clamps and a 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 are also developing ways to liquid cool the entire electric motor, including the copper windings by using special liquids which will not short out the motors in order to create the most efficient system to date.
