What works well on an LT1 Camaro is not necessarily going to function properly on a vehicle used for towing a race car. This is why Vortech does not rate its supercharger systems in terms of absolute pounds of boost or PSI. Make sure you are always in the know. Step 1: If you tend to drive with a "heavy foot," your mileage may suffer. When installing the pulley, apply a small amount of anti-seize on the input shaft and key, and then slide it on. Vortech Engineering, LLC has conducted extensive testing of most intercoolers/aftercoolers currently on the market. This is the most frequent cause of fuel pressure problems. Check the fuses to make sure the current is flowing to the pumps, check the electrical ground for the pump, also check the voltages at the pump to make sure adequate voltage is present in the system. Second, it acts as a dampner to "soften" the transition in the curve. Vortech can assist you with general guidelines but we do not recommend brands, or specific combinations. Vortech supercharger systems offer more HP per dollar than any other single engine modification. You can use mineral based, synthetic blend, or full synthetic oils with a Vortech supercharger system as long as the oil meets or exceeds vehicle manufacturer recommendations. 2.90" pulley, with or without Sur-Grip®. Vortech has developed systems which are substantially more effective at lowering discharge temperatures without causing driveability problems and pressure drops thru the cooling core and ducting. 3.20" pulley, with or without Sur-Grip®. Vortech supercharger systems are designed to fit neatly under the factory hood and they 100% complete, even down to the wire ties. Most computer chip manufacturers produce products which richen up or lean out fuel delivery and advance ignition timing. Continue Shopping Go To Cart Go To Wishlist. Vortech Engineering, LLC neither condones nor condemns the use of oil additives. Nearly all of the intercoolers/aftercoolers available on the market have poor effectiveness and actually can cause parasitic losses equal to or greater than the power gained by installing a intercooler/aftercooler. The vacuum screw acts like a vacuum regulator. 50-state emission legal (unless otherwise noted). Vortech systems are designed to work within a reasonable margin of safety yet modified engines can easily yield improvements exceeding 100% (this may require the additional changes to the supercharger, fuel system, ignition system, computer system, and internal engine and driveline components). Notify the vehicle manufacturer if either of these situations occur. First it will lower the slope of the curve set by the calibration ring. Either statically (the pulleys are misaligned due to an installation or tolerance problem) or dynamically (the loading or unloading of the system), mainly the mounting plate causes misalignment due to flex or movement. We suggest following the manufacturers recommendations concerning oil type and oil change interval. without retuning the computer and fuel system to accommodate such changes. Most other modifications available require specific matched parts, in-depth tuning, are not smog legal, and won't produce the performance gains you'll receive from just the addition of a Vortech supercharger system. Enter your crank pulley diameter in inches: Enter your engine rpm at shift: Enter your supercharger pulley diameter in inches: Your impeller speed: V-1 / V-7 Calculator. What pulley will i need to make 10lbs with that setup? I am running a Vortech Si trim blower as well. It is important to recognize that Vortech has the most efficient supercharger on the market, which translates to less horsepower required to operate the supercharger, cooler discharge temperatures and boost available sooner in the RPM range. Made of 6061 T-6 aluminum, hard anodized and built to SAE standards. The FR-S/BRZ/86 system uses Vortech's V-3 H67B supercharger. 100% complete, even down do the wire ties, making installation and ownership easy and trouble free. Test results indicate that for street driven purposes below 8-9 PSIG, installing an aftercooler has marginal effects when using a Vortech supercharger (due to the high efficiency of the supercharger). Supercharged engines, not unlike turbos, operate in vacuum almost all the time. I'm piecing together a vortech kit to put on my 96 cobra. If you wish to have your Vortech system professionally installed, international turn-key installations are available from your nearest Vortech distributor (please call Vortech sales for your nearest authorized Vortech distributor). Cam selections are best discussed with various cam manufacturers. Octane boosters are not required but may improve performance in severely hot climates or under circumstances where a heavy load is placed on the engine for an extended period of time such as racing or towing. The oil must be drained gradually downward with no dips, allowing the oil to enter the oil pan above the oil level. When discussing the cam with a manufacturer make sure they understand a Turbo cam or a cam for a Roots style supercharger is different than a centrifugal supercharger cam. so, l was wondering if someone knows what size it should be? The next smaller size pulley will create more boost than you have now. hg then the pressure will start to increase. Do not measure with caliper resting in the "valley" of the ribs/grooves, or on the outer lips/flanges. A Vortech supercharger system will not affect the engine durability. Stock is OK. Generally speaking, the supercharger and the cam do the same thing (increase volumetric efficiency). A 30 to 50% horsepower improvement, depending on the application. Supercharged applications should have excess capacity rather than inadequate capacity as the damage that can be incurred is far more expensive to repair than the cost of the fuel pump. hg the upper chamber of the SFMU will only see 5 in. They feature special internal modifications that are compatible with cogged type belt drive systems. It is also recommended that a small amount of blue Loctite be applied to the threads of the retaining bolt prior to inserting into input shaft and then torque to suggested 25-30 ft./lbs. Make sure the FMU lines are connected correctly at the fuel rail and the FMU. CNC machined for maximum surface contact. For severe duty or racing, it is suggested that you install an oil cooler and filter. do i just take a tape measure and measure across it to get the diameter in inches? Misalignment can also be caused by over-tightening (and failing) of the belt which may be detrimental to the pulley bearing. Choose from 6, 8 or 10 rib configurations. This is a simple task and can usually be accomplished in 10-15 minutes. 2.80" pulley, with or without Sur-Grip®. Some non-Vortech pulleys available do not provide the precision fit and balance which are essential for performance and durability and are therefore not recommended. If it is too small, open it up with the scissors a little more and try again. 3.10" pulley, with or without Sur-Grip®. We sell extra grip supercharger pullies for Vortech, Paxton, Whipple, Procharger, VMP and more. The adjusting screw sets the static pressure level of the unit. For continuous heavy-duty racing, off road use only, use one heat range colder than stock and reduce the gap to 0.032 to .040". However, the increased mass of the intake air makes the exhaust system flow more than it was originally designed for. By adjusting the main screw any initial static pressure can be set. The air/fuel ratio must change from 14.7:1 (stoichiometric) naturally aspirated, to about 11.5:1-12.0:1 (rich) under full boost. It may add 35 to 100 additional hp with no other changes (depending on the application, engine, and boost level). Vortech engineers each supercharger system to produce maximum performance at safe boost levels on stock, unmodified engines. For best performance results, initial timing should be set at the maximum amount that does not cause detonation. You can use this to judge how much boost you will make but, only if you use a few different pullies and compare their boost level to the efficency. That's why Vortech offers a wide array of superchargers designed to fit engines from 1.6 liters to 1,500+hp including the V-5, V-9, V-1 S, V-1 SC, V-1 T, V-1 R, V-4 J, V-4 X, and V-4 XX and V-4 Z trims. Right now lm running 8psi and lm trying to get a 10psi pulley. Steel pulleys may rust themselves to the shaft if not lubricated. Vortech supercharger systems are designed to use stock fuel injectors in most cases or have additional fuel system provisions in the supercharger system. In simple terms, it takes fuel to make horsepower. Often belt slip is noticed when the system squeals, squeaks or boost falls off. is added to your shopping cart. hg even though the engine manifold pressure may drop 18 in. There still exists the very real possibility of supercharger damage when using this type of drive, but this special configuration is more tolerant. With Vortech, most models are upgradable to the latest technology. Using a set of calipers, expand to slide over the center of the ribbed area and rest it at the top of the ridges, rotating caliper slightly to either side to help keep caliper ends from slipping into an individual groove. Vortech and Paxton Supercharger Drive Pulleys The easiest and most effective way to get more power from your supercharged motor. How much boost did you see with that pulley and those mods. Excellent technical support from factory-trained knowledgeable and enthusiastic personnel. Because a great number of variables and the fact that leaning out fuel delivery or adding ignition timing to an engine under boost can cause damaging detonation, Vortech cannot recommend these products unless specifically programmed on a dyno with your actual vehicle. The measure of pressure above atmospheric pressure. Yes, the Vortech T-Rex fuel pump can operate independently. Joined: Feb 19, 2008 Location: Hanover, PA. Additional information is available at the Specialty Equipment Market Association (SEMA) website www.sema.org. Detonation at high engine RPM is generally caused by a lack of fuel or improper ignition timing advance setting. If the centre distance (C) is known, belt length or pitch length can be determined as follows: So if you know the distance between the center points of the pulleys, and their diameters, you can calculate the length of belt you need using this formula. When rating our systems, we rate them conservatively for the average vehicle owner and the pounds of boost on the gauge (PSIG). The installation of Vortech products, except those defined as "for racing use only" do not void the new vehicle warranty nor should they cause the vehicle to fail emissions tests. Place your pulley face down on a flat surface, then put your ruler or caliper on top, measure from outside edge to outside edge across the circle of the pulley. So it can be used to "fine tune" the pressure vs. boost curve. Vortech offers bolt-on supercharger systems for most popular GM, Ford, and Chrysler cars, trucks, and SUVs. The California Air Resource Exemption Number of each Vortech supercharger is stamped on the serial number identification tag. Use caution when changing supercharger pulleys. Riskeman New Member Established Member. (NOTE: the gap requirement varies per the application and intended use). On other applications, it may be more convenient to mount the bypass valve on the intake plenum. Vortech offers a unique line of air-water aftercoolers called Maxflow Powercoolers that cool the intake air for improved power, reliability, and consistency allowing more timing, less fuel, and reduced chances of detonation. Vortech is used and recommended by the world's finest tuners like: Turn-key installations are available direct from these tuners and many other authorized Vortech distributors (call for your nearest distributor). I also run cats and my IMRCs. The following items are included with every system at the time of purchase: Vortech Maximum Support:3-year supercharger limited warranty is available with all complete systems. Optional supercharger upgrades are available to achieve 25+ PSI (requires fuel system, internal engine, and computer modifications). Racers also exchange pulleys to bring the boost in right where they want it to match their gearing. i dont remember seeing a part number on it but i could be wrong. Pulleys Available: 2.60" pulley, with or without Sur-Grip®. It is not suggested that the 190 LPH fuel pump be used without the T-Rex fuel pump. Tyler walks through how to use our ZZP Pulley Puller to remove your stock pulley and install our ZZP modular hub and pulley. The only Vortech supercharger designations that may be driven with a cogged type belt drive are heavy duty models. With its new patented oil control system and state of the art centrifugal compressor stage this V-3 literally blows away the competition. If the fuel pressure falls off while the system is in boost, this is usually an indication that the fuel delivery is inadequate and the entire fuel system needs to be evaluated to ensure that all portions of the systems are functioning. About 25-30 ft./lbs is suggested for the retaining bolt. Drain restrictions, kinks or returning the oil below the oil level may cause a severe windage problem that consumes significant power and generates heat, supercharger seal failures may also result. Compressor Matched Systems:Compressor Matched Vortech supercharger system ensures that you will get system ensuring you'll get the proper supercharger for your specific application. I don't wanna blow my motor just yet since its stock and that seems like a lot of HP for a stock motor. can be built into the engine. To properly function, the T-Rex should be fed by a high flow unrestricted hose route. Steel pulleys may rust themselves to the shaft if not lubricated. ).
