So many of our customers add our Super Pro vacuum pump to their dry-sump system to develop the 20-plus inches of vacuum they desire.. The above policy is currently in effect, has been in effect since September 2002, and has not changed. also be the ideal components for an 900 CI Pro Mod Engine that turns 7800 RPM while trying to maintain 22 Hg.? Shown top right is the GZ Motorsports 1-inch crank mandrel and three different Gilmer pulleys. Thank you! While I would not suggest their use on stock vehicles, the LSX platform appears to work well regardless of modifications, and the pump eliminates the intake oil contamination that platform appears to have as a result of the PCV system, says Zucco. Application (for the pump) was 01' LS Camaro/Firebird and I bought the pump from NAPA for $70. Both CFM and vacuum will diminish as the smog pump gets hotter resulting in inconsistency. Established in 2002, STAR Machine specializes in crankcase vacuum technology for the motorsports industry. With eight distinctly different mechanical pumps and two electric pumps, STAR Machine has an ideal vacuum solution for any racing application. This move, however, is very much dependent on ring type, cylinder finish, ring land tolerances and even stroke length and engine speed, all of which affect the frequency and dynamics of piston reversal and its effect on ring performance. These features all contribute to pumps which operate with less friction, less heat and less wear. Mating surfaces are o'ringed to insure sealing. This is the most comprehensive vacuum pump warranty policy in the industry. Nitrous system was NOT turned on, electric pump was NOT turned on, this pull was NA. Note for those with BOOST that may be concerned about possible check valve failurethe pcv valve acts as a check valve if the flow direction is reversed, so an in-line check valve failure under boost conditions would make the pcv valve revert to it's highest restriction mode. It is turned on when the intake sees 3psi of boost. Simply loosen the jamb nut and turn the head (CW) to increase or (CCW) decrease the vacuum set point. High-end systems running as many as five or more stages often dedicate all but one, sometimes two, stages specifically to vacuum. Engines running on alcohol have always produced lower vacuum readings. Extensive research and development, on and off track testing and feedback from past and current world champion racers and engine builders has led to what STAR Machine has to offer. Made from 6061 billet, it can be easily disassembled for cleaning and works with any vacuum level. Whatever the case, it alerts the engine tuner who can then take steps to rectify it. Smaller engines use smaller pumps and lines while large engines are just the opposite. In effect, a dry-sump pump is also an external vacuum pump. A worthless number unless you plan to blow up balloons with it. We look at every pump application on an individual basis to ensure you get the correct pump for your application. External vacuum pumps are the ideal choice for hot street engines, bracket racing engines and other performance applications such as off-road racing or drag boats. GZ offers a a number of breather tanks, bottom, including this model designed for C5 and C6 Corvettes (PN BT2) but can be adapted to other applications. On the end of that exhaust hose, there's a large check-valve that allows the pcv valve to draw a vacuum without the electric pump being turned on. Vacuum pumps require a dedicated belt that does not drive any other components. Here's why: The specialty fitting is then welded at a 45-degree angle into the hole, which helps to create the scavenging effect the exhaust uses to help draw crankcase pressure from the engine. Because I went through several iterations of the design the fan had to be modified to fit onto the shaft and in the end I had to glue it onto the shaft. Engine builders still debate the amount of vacuum required to neutralize crankcase pressure with optimal effect on windage and ring seal, while still minimizing combustion chamber contamination. While the rotating assembly is largely credited with creating windage in the crankcase, we must also remember that with pressure in the crankcase, rapidly descending pistons tend to pump wind toward the rotating assembly, exacerbating windage and parasitic drag. This location also allows ambient air to flow directly into the pump, instead of only heated crankcase air, helping cool the pump thus reducing parasitic loss. Buying a quality exhaust crankcase evacuation system or crankcase vacuum pump kit can be overwhelming and confusing. Due to their design, smog pumps also have very poor maximum potential vacuum numbers. This action relieves blow-by pressure under the rings, reducing windage and contamination. 1969 fastback street car project underway. Port locations with respect to vane timing have been optimized. Nothing we print here will convince you that our service is different than anyone else. How many inches of mercury will it pull ? Moroso regulator (PN 22633), top left) screws directly into the vacuum pump instead of a valve cover to prevent pulling excess oil out of the crankcase. For a better experience, please enable JavaScript in your browser before proceeding. Sounds good. The key to getting the pump to last was getting the pump away from any heat source, along with making sure that any crankcase fumes were cooled off after going through the oil separator and running through the smog pump. An external line is often conveniently connected via the unused mechanical fuel pump port on small- and big-block Chevys. During the 1980's and into the 1990's, serious engine builders who realized the potential advantages of crankcase vacuum utilized these pumps. Site content is 2022 by Star Machine, LLC. Racers often see the worst vacuum readings earlier in the racing season when the air is colder and the engines run richer due to greater air density, adds Hall. Those not familiar with history are destined to repeat it. They were readily available in junk yards and auto parts stores at a reasonable cost. Why reinvent the wheel ? Pressure and oil mist evacuated from the crankcase is discharged to the external breather tank that vents the pressure through a filter and contains the excess oil for periodic draining. There are benefits to buying a crankcase evacuation system. Running a high-volume pump is often necessary. Yellow line- crankcase vacuum. If we could conveniently measure oil volume it would tell us more about the system than oil pressure, explains Hall. Most of these pumps are basically the same internally, just clocking of the inlet/outlet is different. It also introduces harmful contaminants to the lubrication system and poisons the incoming mixture in the combustion chamber. That's a constant savings of almost 8hp at 1500rpm. I couldn't figure out where to mount it, what you have done gives me an idea. That makes vacuum pumps one of the best bang-for-the-buck products available for both high performance and racing applications. At STAR Machine, vacuum pumps are not just another page in a sea of products in a catalogue. If you're a bracket racer going rounds in the heat of the summer you may want to give this consideration. We encourage you to ask Anyone with a STAR Machine vacuum pump about their experience with our company. Many engine builders monitor crankcase vacuum throughout the engines power range. Because the amount of alcohol is nearly double that of gasoline, the ring tends to hydroplane off the cylinder wall on its way upward causing both oil contamination and less ring seal during combustion. Pump speed is determined by the drive ratio between the crank pulley and the pump pulley. All our regulators have screened inlets to keep dirt out of our pumps and out of your engine. Pump manufacturers like GZ Motorsports and Moroso have each addressed this in their own way so the end consumer can make a thoughtful choice based on his needs and interpretation of their individual pump features. Includes a billet clamp for remote mounting and a -8AN drain plug. Neat. Electrical parts excluded. We are very proud of the relationships we have forged within the racing community and cherish the privilege of our customers' business. Ford F6ZE-9A486-DC Wet sump engines can now run as much as 16 to 18 inches with modern piston-and-ring technology, he adds. One guy claimed it mellowed out his engine that had a borderline too large duration cam for the street. Pump choice is primarily based on engine size and horsepower level with appropriate attention to pump speed and vacuum line size. I have used a GM smog pump to good effect. Make sure that the exhaust fitting is positioned between the 5 oclock and 8 oclock position if you can, suggests Hall. When researching exhaust style systems, if your vehicle doesn't have mufflers, confirm it will be compatible. Next, the headers are reinstalled (if removed) and the check valves are threaded into the fittings with thread sealant. Clean arrangement with the pump pulling vacuum from both valve covers. I Have thought that would work. 8"Hg @ 18v If an engine loses power at a certain point in the rpm range for example, the data logger may show a sudden increase in blow-by pressure, indicating the likelihood of lost ring seal due to high-speed ring flutter or detonation, among other conditions. Please select the checkbox to SignUp for text alerts, Save $20 Off $200, $50 Off $500, $100 Off $1000 Orders - Promo Code: SUMMER, JEGS expert is ready to answer your questions. 7 of top 10 Finishers for 2010 in NHRA Comp Eliminator currently use our, 9 of the top 12 2010 Division 1 finishers in Comp Eliminator currently use our. Next is to drill a hole on the top surface of each header collector. Since the idea of crankcase vacuum was a relatively new concept at the time, there were no purpose built/aftermarket vacuum pumps available to the racing industry. Vacuum may draw oil out from between the bearings and journals like a straw; thus, flow increases and the system pressure drops. External crankcase vacuum pumps will provide significant power gains on both racing and high-performance street engines, primarily by promoting superior ring sealing. Anyone who owns an air compressor is aware of this. Today, manipulating the pan vacuum with a dedicated pump such as those offered by GZ Motorsports and Moroso is more effective and gives the engine builder another tuning tool. Power gains ranging from 10 to 35 horsepower are common. The electric vac pump is a Delco 215-425, available new from ebay or amazon for around $100. We specialize in vacuum pumps; it's all we do. More current national records have been set in NHRA, IHRA and PDRA using STAR Machine, 8 straight IHRA Pro Stock National Championships won using our. We have run our own 632ci above 16 inches for many runs with no issues on the wrist pins or exhaust valve guides.. 2022 JEGS High Performance. The check valves prevent exhaust gasses from flowing back into the engine through the valve covers. It includes the VP 104 pump, pulleys, Gilmer belt, braided hose, breather tank and vacuum-control valve. JavaScript is disabled. You are now signed up to receive great E-Mail Offers! It may include fuel, exhaust gasses, carbon and other contaminants. Morosos regulator (PN 22629), bottom left, offers 360-degree adjustability. Here's a RacePak graph showing crankcase vacuum during a 6.25sec long WOT 3rd gear pull using ONLY the pcv valve as the vacuum source. JEGS Universal Crankcase Evacuation/O2 Fitting Kit, Mishimoto Universal Baffled Oil Catch Cans, Mishimoto Universal Sight Glass Oil Catch Cans, Allstar Performance Crankcase Evacuation System, Mishimoto Universal Compact Baffled Oil Catch Cans, Mishimoto Carbon Fiber Baffled Oil Catch Cans, Vibrant Performance Universal Oil Breather Catch Can Tanks, Aerospace Components Vacuum Pumps and Vacuum Pump Kits. The pumps were also never designed to be connected to a crankcase on the intake side. Quick crude example In any other position, excess oil will build up at the bottom of the pump and may cause the vanes to stick in the rotor slots.. Coyote-Powered And Gunnin For 9s: Bondo Bird Is A Purists Nightmare, SEMA 2021: Turbosmarts Straight-Gate50 Is Redefining Wastegates, A New Pro Stock On The Horizon? The amount of vacuum produced with a dry-sump pump depends on pump speed, the number of stages and the amount of time each stage spends scavenging oil or creating vacuum. No longer do you have to settle for a compromise when choosing a vacuum pump. The electric pump pulls around 4" Hg on 12v, about 8" Hg when powered by a 18v cordless tool battery pack. As a bonus, WOT at 7000rpm, the low-tension shortblock would have about 36 more hp on tap. Mario Johnson Reveals Spectacular New 67 Camaro For 4.84 Shootouts! freq may vary. These gains are on par with and sometimes exceed those provided by a cam or intake manifold changes and pump systems are much easier to install. From a performance perspective, the smog pump is approximately 50% less efficient at making vacuum and 20% less efficient at free flow (CFM) than a well designed aftermarket vacuum pump. Come join the discussion about performance, production numbers, VIN decoders, modifications, troubleshooting, power adders, DIY tutorials, and more! We promise not to use your email address for anything but exclusive updates from the Power Automedia Network. We don't use vague terms such as "lighter than" or "more volume than". What few things I've heard about using these electric vacuum pumps has been pretty good. A pump-mounted regulator also reduces additional oil from being scavenged from the crankcase when the vacuum exceeds the regulator set point because its location is outside the crankcase. 1"Hg @ 9.5v All Star Machine vacuum pumps are warranted for one year from date of purchase to be free from defects in material and workmanship. The pumps flow freely internally when not running, so a failed pump will still vent crankcase pressure and not damage the engine. Here's a list of vacuum drawn at various voltages The hoses are -12 lightweight pushloc (3/4" id), and fit the electric pump's ports perfectly. Our pumps incorporate precision coating processes to reduce wear and friction. Some users will require modifications and/or minor fabrication if they plan to mount the pump in a non-standard location. With a pump mounted inside the car, the pump cannot be heard when the engine is running. Crankcase pressure hurts power by upsetting ring seal, and it opposes piston motion by creating drag and windage. The crankcase evacuation system installation is then complete. Direct consultation with the manufacturer will ensure the best possible choice. Some orders may take longer to arrive due to shipper and supplier delays. These steps included special reverse-lip crank seals and silicone sealing the valve covers, intake manifold and so on. Hall also cautions that pulling too much vacuum in a wet sump system can affect overall oil pressure. Typically, a crankcase evacuation system with mufflers is required as backpressure is needed for it to work properly. With this hybrid pcv/electric evac setup, there is no need to worry about over-heating the electric vac pump, as it's only used for a few seconds at a time when the nitrous comes on. So cool evac fumes with no oil vapor getting to the pump was key. This pressure is readable with a vacuum gauge. They are advertising 100 CFM from one of their vacuum pumps. Blue line- WOT switch Conventional wisdom says that 12-to-14 inches of vacuum is required to generate beneficial power gains. We provide you with the exact weight, dimensions and performance of our products. The existing exhaust gas from the engine through the headers creates low pressure, which draws crankcase pressure from the valve covers through the hose and specially-designed collector fitting. 1989 Saleen 414 358cid SBF 2.8L Kenne Bell S/C. Each pump is dyno tested and must meet or exceed the free flow and peak vacuum levels STAR Machine has published in our Performance Graphs before it is shipped. Properly sized modern pumps easily overcome these smaller vacuum leaks while using the control valve to maintain the desired vacuum. The Moroso oil breather tank (PN 85467) provides air/oil separation through interior baffling made from mesh media. When the pull ended at 6250rpm, even without the electric pump running the crankcase still had 3.9"Hg of vacuum left. If you are trying to learn more about a crankcase evacuation system for an SBC, BBC, SBF, BBF, SBM, BBM, or other engines, we can help you along the way. Shown are two vacuum relief valves from GZ Motorsports (PN 101A, 101B), top left. Pretty neat IMO & you don't have a bunch of $$$ tied up in it. When buying re-mans from parts houses, some have reported that their's came without the cover, so be sure that the pump you buy comes complete before you order it. NHRA Reveals A/FX Exhibition Class, Improved ring seal by relieving crankcase pressure below the rings, Reduced friction by allowing lighter tension rings, Reduced windage around the rotating assembly, Minimized cavitation (in wet sump applications), Improved bay to bay breathing in Y-block configurations, Improved power via reduced mixture contamination.
