Compression Ratio affects on supercharging Discussion in 'The Blower Bistro' started by F8L SN8K, Jun 25, 2009. Compare products. This still is very dense air, which is why the engine responds with such a huge power increase. Dale Vaznaian and Karl Staggemeir have been working to perfect the concept of compressed-air supercharging to make ridiculous amounts of horsepower andmake it practical for use on the dragstrip or even on the street. To help ensure that CAS systems are optimally configured for each application, each of the three major functions (Storage, Metering and Control) are performed by a subset of components known as Modules. Efficient supply of contamination-free air for the operation of fuel cells … Find out more. The safety valve and Bosch throttle-body direct the pressurized air into what Staggemeir calls the "ejector valve." The intercooler is responsible for this cooling process. For supercharging an engine, there are several approaches taken by engine builders that are different from those of turbocharging. The next component in line is the electronic safety valve. Cylinder head modifications; Air filter kit; Coolants. As the air is compressed, it gets hotter, which means that it loses its density and can not expand as much during the explosion. The bottle valve is connected to a -20 AN hose and fittings, which is the largest practical hose diameter the company can use. Compare Blackridge Accessory Air Tool Kit 21 Piece 156494. 2018-2020 Ford 5.0L Mustang GT Supercharger Systems. Innovation. But during the Second World War as battles raged over Europe and the Pacific, supercharging came into its own, giving aircraft the horsepower edge in a Compressed-Air Supercharging. More pressure generates more heat in the air. With the aid of extra oxygen the fuel in the cylinder would start burning at a faster rate. So take that idea and now consider we are releasing air that has been compressed to 3,300 psi. With the baseline complete, we didn't change anything on the small-block except hook up the discharge tube from the CAS system and add Rockett Racing Brand 114-octane race gas, just to keep the 9.2:1 engine free from the possibility of detonation. The inherent purpose of a forced induction system, combined with its … In 1971, Mickey Thompson experimented with a somewhat complex mechanically controlled system on one of his Funny Cars and other racers also tried these systems that appear to have been the work of an engineer named Bob Keane, who owned Keane Engineering. background-color:#FFFFFF; 77 likes. ambient air temperature about 50 degrees F. In order to cool the compressed air the given heat exchanger using the same ambient air would have to be huge. The photos make the system look cumbersome, but the system's control portion located near the engine could be easily packaged in a box on the inner fenderwell of most muscle cars. Right out of the box, the little 355ci V8 managed an honest 422 normally aspirated horsepower at 6,100 rpm. Of course, your engine will need a fully-boost-capable fuel-delivery system and preferably multi-point EFI with big injectors to flow the necessary fuel. Vaznaian and Staggemeir don't have a retail price as of yet, but they expect to see an 800hp system complete with a single bottle sell for around $6,000. By jacking the fuel pressure to 60 psi, they created enough fuel flow to feed the engine at peak power. The main negative factor is it increases the chances of pre-detonation, which is caused by the compressed air being heated excessively. I went a point lower than stock with the intention of adding a T-Trim! 714-916-3328, © 2020 COPYRIGHT COMPRESSED-AIR SUPERCHARGING. The Edelbrock single-plane intake uses a standard 4-bbl style throttle-body feeding air to eight 44-lb/hr injectors. In turn each module can be tailored precisely to your vehicles’ requirements. Multifonction, le compresseur à air comprimé sait se rendre indispensable. Blackridge Blackridge Air Spray Gun Kit HVLP 4 Piece $99.99 ^ ★★★★★ ★★★★★ (23) Add To Cart. The test procedure was much like the way we test with nitrous oxide. As the pressure in the bottle drops, the effect diminishes at the discharge point, but at the same time, the air inside the bottle is cooling, which tends to help in maintaining a very cool discharge temperature. Staggemeir tried a couple of runs with low boost of 5 psi. $23.98 $ 23. Hang tight with this, and we promise no math. info@casupercharging.com The information provided below should help you determine if Compressed Air Supercharging is right for you and your application. K Supercharger FAQ Rover K-Series CM: hangar/faq_ksc_v1.0/11/11 Page 2 Q ... had learned through our years of supercharging the Toyota 2ZZ engines. But hot air has less oxygen density and therefore would limit the amount of charge, and if more of it is present than the threshold of detonation is much easier to cross. Such is the case with compressed-air supercharging. Like many automotive technologies has been around longer than most think. The cam also has a slightly wider 113-degree lobe-separation angle (LSA) to help manage the boost so the pressure doesn't blow out the exhaust during overlap. The air compressor is powered through a series of gears or belts attached to the crankshaft. The supercharger scroll acts as a chamber to collect the air molecules and channel them towards the supercharger discharge tube so they can be forced into the engine’s air intake. Ordinary compressed air cylinders feature small diameter necks that are configured to … The impeller design inside a supercharger compressor is very similar to a turbocharger’s compressor impeller. Unfortunately with the integrated supercharger-manifold design of the MP45 kit, a physical air-to-air or air-to-water intercooler is not feasible. Sounds simple enough, so what's the catch? The only California one I've seen is at the Kettleman City supercharger. Magnuson is proud to announce our brand new under the hood HeartBeat supercharger system for the Chevrolet Corvette C6. Supercharging and forced induction unit information will cover mechanical, liquid, and air supercharging in the forms of the various superchargers, turbochargers, nitrous oxide, and compressed air systems. There are very few new ideas in the world of high performance. Compressed air instead of a supercharger. Paxton 2018-2020 Ford 5.0L Mustang GT Tuner Kits. color:#000000; Superchargers for Cessna, Cirrus, Diamond and Homebuilt Aircraft. Our patented aircraft supercharger systems are F.A.A. Your information will be collected and used in accordance with our  Privacy Policy. Staggemeir tells us the air leaving the bottle valve exits theoretically at around 200 degrees Fahrenheit, and they have actually measured it at 140 degrees! The newly developed supercharging system for a 50cc – 125cc engine provides more than a 50% increase in power. Low rates to 7.9%. Expect to hear much more about compressed-air supercharging in the coming year. To ensure that CAS compressed air supercharging systems are correctly matched to customer requirements, each CAS system is constructed from three main modules: Air Storage, Air Delivery and Boost Control. Our team has developed a compact and powerful mechanical device for motorcycles. Our Team. If you were from Melb I'd recommend you else where. The main negative factor is it increases the chances of pre-detonation, which is caused by the compressed air being heated excessively. Diffuser with Integral MAP Sensor (4150 Style Holleys only). Compress and store a large volume of air into a high-pressure tank. We are partner of various OEM manufacturers and supply in the series as Tier 1 supplier.Our compressors are unique in the world and ideal for innovative projects of any kind … Using compressed air, because this system radically reduces the inlet air temperature to 0 degrees, the formula tells us we should make an enormous gain. Branding, Social & Search. Be prepared to be amazed. color:#FFFFFF; The only fabrication would be mating the CAS 3-inch inlet duct to a fresh-air inlet tube. Post by M3GTDRIVER » Sun Nov 30, 2008 9:27 pm . All this happens very quickly and is very transient, yet all of these actions combine to create the power increase that we saw in the testing. Gaseous Intercoolingtm or water/alcohol injection contributes to the ideal air fuel ratio4under boost. At the heart of the system the rotors of the supercharger flow air fed in from the intake and deliver an increased volume of compressed air to the engine. I think that could be an issue, but then a "real" supercharger would cost more horsepower to run! Il permet tout aussi bien de nettoyer, de gonfler des pneus, de peindre, de sabler ou de clouer. background-color:#000000; We stabilized the engine at peak horsepower at 6,100 rpm and then hit the button on the compressed-air supercharger and allowed the dyno to stabilize while we captured the numbers. The essential message here is that the compressed-air supercharger concept can deliver far greater density numbers. A turbocharger, colloquially known as a turbo, is a turbine-driven, forced induction device that increases an internal combustion engine's efficiency and power output by forcing extra compressed air into the combustion chamber. The compressed air requires additional fuel and the denser fuel/air charge makes a more powerful explosion when ignited, that is, versus a naturally aspired engine. Financing is now available to upgrade your Cessna or Cirrus with a supercharger. In 2015 Nord Compo North America was created to better service a growing … It allows the user to produce a sophisticated linear power curve as opposed to a simplistic on/off switch. Welcome Quick view. You can imagine how hot the air and tank becomes when your local scuba shop squeezes the air to 3,300 psi. Compressed air generation. Our supercharging kit utilizes a 15 GPH (gallons per hour) water/alcohol injection nozzle. Each vehicle is unique in some respect, be it storage capacity requirements, packaging considerations or performance requirements. We talked with Rockett Racing Brand's Tim Wusz, and he said one possible explanation for the timing was that extremely dense, cold air will tend to reduce the fuel's capacity to vaporize. APR’s Engineering Teams are pleased to present our second iteration of the Audi 4.2l V8 FSI Supercharger application. from $849.99. The automatic shut off is easily set by the twin indicator arms in … Producing over 537 HP and 443 ft-lbs of torque, APR’s B8 S5 Stage III adds over 187 horsepower which completely transforms Audi's latest coupe to … Each bottle is fitted with a CAS-specific 58-inch-id gate valve, with a 1,000-cfm flow potential. Remember, only 5 psi of boost pressure is already delivering more than a 55 percent power increase. When choosing a cylinder head, it is best to choose a cylinder head with bigger intake ports, especially if the fuel being used will be alcohol. Vaznaian and Staggemeir are working on a tubbed '68 Camaro with both the small-block and a CAS system so we can return in a few months to report on testing the car and system on the dragstrip. Along the way, they had to design and build nearly all the components because the parts needed didn't exist. This is a larger valve located inline with the normally aspirated inlet air tract. This is decent power within reason for a mild small-block. It's also important to note this was a near-production system, but CAS still has more work to do before a complete kit is ready for installation in a car. ? 98. JEGS offers supercharger kits for bolt-up performance and horsepower for many vehicles like Mustang, Camaro, Corvette, F150, Chrysler Hemi's and others. color:#FFFFFF; In fact, we tried retarding the timing from 42 to 36 degrees, but this resulted in losing 50 hp. from $6,272.99. Onboard compressed air setup on a Mazda Miata to eventually set up for occasional drag racing. That's an impressive 414hp gain—a 98 percent power increase—and this was with the CAS system operating at 1,000 cfm. *Blow through MAF design for the cool BOV sound. Compare products. Read Book Compressed Air Engine Kit Compressed Air Engine Kit connections. The operator eventually binds speedometer readings with air gauge indications and intuitively defines the most appropriate driving mode under the given traffic conditions. air pumps, mechanically complex parts & Computers. As can be seen from the photos, the supercharger sits on the left hand side of the engine bay and receives its air supply via the vehicles stock air intake system including filter. Basically with supercharging all you are doing is forcing up to 150% more air into your intake. This is a very rudimentary explanation of how the Compressed Air Supercharging system functions. A 50/50 blend of distilled water and alcohol weighs about 6 pounds per gallon at 60 degrees F. That’s 90 lb/hr (15 x … The Edelbrock Stage 1 Supercharger kits for 2009 through 2019 Ram 1500 trucks features a high-capacity air-to-water intercooler, integrated bypass valve to help … Roots blowers are generally lower. font:12px verdana,arial,helvetica; The only thing a touch out of the ordinary was that it required 42 degrees of total ignition timing to achieve this horsepower. More air requires more fuel, resulting in a bigger bang which increases power. .hdr1 { To no one's surprise, the combination of below-freezing inlet air with a conservative amount of boost equals major horsepower. Taking the above example, reducing the inlet air temperature to 0 degrees, that's a massive 200-degree change, which would mean the engine gains 20 percent power. Compress and store a large volume of air into a high-pressure tank. The best part is the CAS system puts down some serious power. This motor is powered by an attachment to the car’s battery which brings up an inherent problem with electric supercharging. The secret behind Rotrex’s low noise level is … ASA has been developing and producing high-speed, mechanically driven centrifugal compressors for over 30 years. We decided that using a basic fuel-injected small-block Chevy would help make this entire program easier to digest. The hose is connected to a sizable pressure regulator located near the tank. This low-pressure, high-speed air is sent through a diffuser which converts the airflow so that it is high-pressure, and low-speed. Selection, Installation and Maintenance of Compressed Air Supercharging System and Components. Internal compression is when the air is actually being compressed before being released into the engines intake. With modern technology, we can often revisit a clumsy, old idea and make it more efficient. This means the heat put into the air has now dissipated, but we will have kinetic or stored energy because we have a bottle with 3,300 psi. Supplying the fuel pressure was an Aeromotive fuel pump and a boost-referenced fuel pressure regulator that added 1 psi of fuel pressure for every 1 psi of boost pressure. Anyone around who knows more about this unique way of supercharging? }. I have seen tunehouses work as they did well on my mates race car. Although air … This means it might require more ignition timing to give the fuel in the chamber additional time to vaporize and burn completely. Now that the cylinder would start burning more fuel, it would start producing more energy on a faster face and then transfer more power through the piston, shafts, and gears to the wheels. Efficient compressed air supply through high-speed drive, radial compression & modern sealing technology … Find out more. One amazing feature of the Compressed Air Supercharging system, is its ability to create extremely dense air at relatively low pressures. Has anyone seen air available at other California locations? Quick view. Pick up today. This creates much higher cylinder-pressure numbers and therefore more horsepower and torque because the increased density delivers cooler air, which equates to more oxygen in the cylinders. And we all know that cold air is more dense and makes more horsepower than hot air. Staggemeir and Vaznaian began their quest more than 10 years ago to create this system. Others available. Nous avons sélectionné pour vous une large gamme de compresseurs à air, des modèles portables 12V aux modèles d'atelier. What is a supercharger? We'll start with the bottle, which is a large, 30-pound aluminum container that looks like a scuba tank. With larger injectors, they could theoretically move even more power. The centrifugal supercharger contains an impeller which spins at high speed to draw air into a small compressor housing (volute). ... the piece that channels compressed air … One question running this system in the car should answer is whether one bottle will support a quarter-mile pass. The idea is simple enough. A supercharger is, for all intents and purposes, an air compressor designed to force large amounts of air through your engine. Introduce the air on demand, and you have a killer supercharger that doesn't create parasitic losses because the engine is not using power to drive it. The basic concept that has been around for decades is that if you lower the inlet air temperature by 10 degrees, this is worth 1 percent power. If Freiburger and Finnegan are writing it, expect leafblowers. The static compression ratio came out to 9.2:1. The practice along with numerous road tests showed that a manometer like a speedometer became an integral part of a motorcycle. Programming, tracking tuning and performance analysis of compressed air Supercharged vehicles. For a camshaft, Vaznaian chose a Comp Cams hydraulic-roller camshaft with 236/248 degrees of duration at 0.050 with 0.520/0.540 inch valve lift with 1.5:1 roller rockers. Manufacturer of Compressed Air Supercharging Systems Another potential benefit to the lower inlet air temperature is that octane may not be as critical a factor as it is with heated air from a supercharger. .hdr3 { The first column indicates the boost pressure that would be indicated on the gauge (psi gauge) with no aftercooling. ProCharger’s Bolt-On kit claims at least 40-80 more horsepower. That s the way ATI designed it to be done. 6 years ago. Some superchargers are referred to as blowers. The CAS System is a uniquely engineered set of components that Store, Meter and Control the Discharge of high pressure compressed air. This mass volume of air, in conjunction with the appropriate amount of fuel, combine to create more power than could be accomplished through natural aspiration alone. Supercharging is also known as forced induction, a technology that’s been used for more than 100 years in applications ranging from blast furnaces to diesel generators. Because the air has cooled, but energy cannot be created or destroyed, the air now will pull heat out of its surroundings. It's entirely possible that additional timing might have resulted in a power increase. Let's run through how the CAS system works and then we'll show you what our testing at Westech revealed with this system on a 420hp small-block Chevy. The main reason nitrous is more effecient is that nitrogen acts as a buffer in the cylinders, and also cools the compression down. As we mentioned, Staggemeir says they have measured the discharge temperature of the air at the bottle at 140 degrees, but by the time the air travels through the 20 AN line and all the fittings, valves, and ducting into the engine, the air has heated to roughly 0 degrees. There were many discussions whether to equip the kit with an air gauge. A supercharging system ( 40 ) is disclosed which comprises a supercharging device ( 28 ) having at least one inlet port ( 42 ) and at least one outlet port ( 44 ), and at least one idle valve ( 30 ) in fluid communication with the supercharging device ( 28 ). Prior to the selection and purchase of a CAS system it is important to thoroughly understand the basics of compressed air supercharging. You can also re-circulate the air to the intake tract if you choose to. This motor is powered by an attachment to the car’s battery which brings up an inherent problem with electric supercharging. Companies, organizations and people that are, or were, involved in manufacturing, selling and servicing, of these systems will also be included in the site. Westech's Steve Brul ran the engine up to 6,100 rpm, Staggemeir hit the button, and the engine immediately responded to the 8 psi of boost with 836 hp at 6,100 rpm.
