weiand 177 supercharger max boost

177 SuperChiller Intercooler, Holley/Weiand. In its current state, our 350 small block featured a four-bolt main block, stuffed with cast internals, including dished pistons. This overheated expanded air loses so much density that even though your boost gauge says the blower is making boost, in reality you aren't putting any more air into the engine than an unblown engine would get. The helix style rotor was developed by General Motors for larger GMC superchargers. SuperChiller Intercoolers are available for 6:71 - 14:71, Holley/B&M, Weiand and MerCruiser supercharger systems. The amount of boost that can safely be run is primarily determined by the compression ratio of your engine and the gas that you are using. Call 800.979.0122, 7am-10pm, everyday. If your engine is not as free-breathing as it could be (because it has a stock or low performance cam, small valves, restricted ports, etc.) A slow turning blower, especially a larger one like a 6-71, would have a lot of low speed "leakage" of boost pressure past the clearances between the rotors and the blower case. Supercharger boost, however, is not totally con-stant. © 2020 Power Automedia. In selecting the proper supercharger for your application, you also need to take into consideration how you plan to drive your vehicle and the approximate boost level desired. Pre-Owned. For 6-71 and 8-71 blowers, Weiand again recommends running a hydraulic cam, as long as you keep the boost level below 10 PSI. You will need carburetors that have a "boost referenced" power valve circuit. 177 SuperChiller Intercooler, Holley/Weiand. With a supercharger, the amount of air and fuel that can be packed into the cylinders greatly exceeds the 100% volumetric efficiency of a highly refined unblown engine. This design has even more "twist" imparted into the blower rotor and does provide more power. But this was using 100-octane race gasoline. Not necessary on our mild 350 in its current state, we suspect the 350 will become considerably more powerful in normally aspirated form in the not-so-distant future. I have a Chevy 350 with a Weiand 177 blower on it, as well as a Holley HP EFI throttle body on top of the blower. Weiand is proud to reintroduce them. Are your air cleaner and carburetor capable of letting in 50% more air? Compare These Parts Talk to the Experts. Two lobe rotors feature thick walls and a solid shaft, which prevent flexing at higher boost levels. Weiand's larger superchargers use three lobe helix rotors. Roots type superchargers first appeared in automotive applications as far back as the 1930s. The key to power for this particular 383ci engine was the 177-cid Roots-style Weiand supercharger, (a.k.a: the blower). I have a PCV system on the car using the port on the back of the throttle body. Using the supplied 3-inch blower pulley and 6-inch crank pulley, the Weiand 177 supercharger produced a peak of 6.3 psi and increased the power output of the 350 to 405 hp and 446 lb-ft of torque. However, this high blower speed will be less effective at higher engine speeds due to the overheating of the inlet air as discussed earlier. The Roots blower is the simplest of all blowers and therefore is also the least expensive. hello all, i have a 302 with dart pro 1 195 heads, jay cam, about 9.4 to 1 comp ratio with speedpro forged pistons. There should be IAT sensor tables that adjust both spark and fuel. This would provide 34° of total timing or if you wanted 32° of total timing, you could line up the mark on the damper with the 2° ATDC mark on the timing tab instead of "0.". Part Number: WND-6791 Not Yet Reviewed Many street supercharger applications will work fine with the stock ignition system, because blown engines make so much low and mid-range power, it is not necessary to rev to high rpm's. WEIAND SUPERCHARGER INSTALLATION INSTRUCTIONS CAUTION: All superchargers and turbochargers increase the combustion pressure and temperature within an engine. It is fairly easy to change the boost to get the best combination of performance and power, but it is extremely difficult to change the compression ratio, especially if you want to lower it. Not much room but much more power avalible with a 250 v.s. sec., MSD Dist.,MSD 6AL ign., MSD Boost Retard Box,MAC 1-3/4 long tube header, 3" exhaust with 2 chamber mufflers,C-4 w/ 3500-3800 stall convertor, B&M shifter, S&W 8 pt. See the operation section of these instructions for details of distributor timing and carburetor modifications. Substantial increases in bottom-end performance. The company recommends a hydraulic cam for these applications - where the engine will not be spun past 6,500 rpm and has several grinds available. Then read across to the right under the boost you want to run and the number in the box will be your "effective" compression ratio. Your distributor should have a centrifugal advance mechanism that has been set up so that the entire advance is in by 2,500 rpm. We state that your boost will fall within a particular range, such as from 5 to 8 pounds, because a lot of factors can cause boost to vary. The company does its utmost to provide the best possible solutions for your needs. This leakage reduces low speed boost pressure, with a resultant decrease in the amount of additional power produced. Disconnect and remove the transmission kickdown and throttle pressure control linkage. The supercharger case is smaller because the two lobe rotor design takes up less area in the case. Under boost, the engine could need up to 40 to 50% more fuel and air, so it's key to pick a carburetor that is up to the task. We will safeguard your e-mail and only send content you request. This is because at lower blower speeds, the clearances between the supercharger case and the rotors allows for air "leakage" with some loss of boost efficiency. The main thing that needs to be addressed with a blower is to make sure that detonation is controlled. Once the motor is warm this will decrease to roughly 1/4″ deflection in or out, or a total deflection of 1/2″. Torque on an engine of this type typically will be in the 400 to 440 Ib.-ft. range. Stepping up to a 7.0-inch crank pulley resulted in a jump to 452 hp and 492 lb-ft of torque. These boost levels are based on 350 or 454 cid engines. Weiand also offers cams for these type of applications. Whether that comes from a hike in compression, wilder cam timing, or increased head flow is irrelevant, but the 177 supercharger has the ability to grow with our power needs (we’ve made 644 hp with it on a wilder 383 stroker). Weiand 6-71 blower kit: 7482: Summit Racing: $3,009.95: Weiand blower pulley, 8mm pitch: 7109-XX: Summit Racing: 149.95 (and up) Holley 750-cfm blower carbs: 0 … You can find your static compression ratio on the left side of the chart.

Build your own custom newsletter with the content you love from Street Muscle, directly to your inbox, absolutely FREE! Although there isn't room to print all the blower pulley/boost combinations we … When the spark plug ignites this compressed fuel/air charge, the resulting combustion causes an expansion of the charge which forces the piston down. How you plan to drive your vehicle is important because you can set up your blower to be more efficient at high engine speeds or more efficient at low engine speeds, or you can arrange for the best compromise for the full engine rpm range. Higher boost levels will cause detonation and engine failure. Power & Performance News is the source for news, tech and products that help you get more performance from your vehicle. If your compression ratio is higher than this, you will have to run less boost. Pictured is the larger Weiand 177, it has a flange mount base on the blower case. Although 33 more cubes per revolution of the bigger blower has to mean something. Interestingly, this means a supercharged engine can make more power with lower reading on the boost gauge. 177 Questions. Enough purchase justification and future speculation; let’s get to the test. Best results are achieved by driving the vehicle under boost and adjusting the unit until any detonation is eliminated. With the use of this unit, you can run normal timing settings which will allow for easy starting and reasonable fuel economy under normal driving situations. All superchargers are built in Weiand's state-of-the-art manufacturing cell and each supercharger is 100% boost tested to help you squeeze out maximum power and efficiency. When you reach 7 pounds of boost, it will be retarded by 7°. Boost is the amount of air pressure created by the supercharger. In the late 1950s, Phil Weiand was in the forefront of the development and adaptation of these superchargers for racing and performance applications. you will typically see the boost readings go up in the higher rpm ranges. With the "boost retard control," the driver can dial in ignition retard with a dash-mounted knob. Again, the 6-71 through 14-71 will outperform the smaller blowers in the high rpm ranges. If you install a Weiand blower and your observed boost comes up on the low end of our estimated range, it means you have a really good breathing engine. For optimum performance at higher engine rpm's, select an aftermarket performance ignition system. Roots blowers have been used on GMC diesel engines for many years.

The company also offers slightly "bigger" cams for the next performance level up. Discussion Starter • #1 • Mar 31, 2013. As engine size goes up, boost goes down if the blower speed and blower size remain constant. If the vehicle is equipped with a cable type linkage, you may simply need a longer cable. Choosing a carburetor is a very important step in building a blower motor. All, has anyone ever upgraded from the smaller 144 CI underhood blower to its larger brother the 177? Blower Size and Type * Please specify which blower and size blower you have or call us at 208-985-7650 to place this order. If an engine has a 9:1 compression ratio, the fuel/air charge will be compressed to 1/9th of its original volume. Then read the new 34° mark like you would read TDC at idle speed. All rights reserved. With a Roots blower, the carburetor functions basically the same as it would on an unblown engine, except it now sits on top of the supercharger. As a result of supercharging, a small displacement supercharged engine can produce similar horsepower and torque to a naturally aspirated larger displacement engine. All of these components are capable of withstanding substantial increases in combustion pressure under proper conditions. We have a line of Tri-Powers, Marine Carbs and Conversion carbs. However, if you follow this chart, you will be close enough that if you do experience some detonation, you should have no trouble controlling it with one of the aftermarket boost retard ignition systems (such as the such as the Holley Ignition P/N 800-450). This supercharger is intended for use on engines with compression ratios of up to 9.50:1 with a maximum blower pressure of 5-6 psi. The blower belt adjustment should be done with the motor cold, and have 3/4″ deflection in or out on the long side of the belt. We liked several things about the Pro Street 177 supercharger (besides the name), including the ease of installation, ability to easily increase the power output, and capacity to grow with our future power needs. It's important to realize that there are no hard and fast rules and the suggestions made here are general in nature. For these guys, the only choice is the symmetrical look and instant boost offered by a positive displacement supercharger all nestled down in the valley of a V8 (where god and nature intended it). Installing a blower is one of the easiest ways to substantially improve a vehicle's overall performance. In each application, this blower comes with its own dedicated intake manifold, along with a 10-rib blower drive, lower crank pulley, and all the necessary support systems accessory brackets. Taking an example to the extreme, the blower choice for an 8,000-hp, Top Fuel motor would be decidedly different than a 400-hp, daily-driven small block. A true blast form the past. These instructions cover the following Weiand Supercharger kits: Application Weiand Supercharger Kit Sizes Small Block Chevy 142, 177, 671-871 Big Block Chevy 177, 256, 671-1471 Chrysler 392 Hemi 671 Chrysler 426 Hemi 871 There are some important differences between these kits. Can you ever have too much of a good thing? Bolting one of Weiand's Pro-Street Superchargers on an otherwise stock small block Chevy will result in an increase of approximately 100 to 120 hp. Increasing the power output of any supercharged combination is a simple matter of increasing the boost. If you have a high compression ratio, such 9.5:1 or 10:1, you will only be able to run a small amount of boost. These are all Roots type superchargers and operate on the same basic principle as all of Weiand's superchargers. We can supply an adapter / base plate as a raw casting or machined to make mounting a Weiand 177 to another manifold. On most street type blown applications running 6 to 7 pounds of boost, approximately 40 to 50% more fuel and air can be packed into the cylinders than in a comparable unblown engine. In the end, we selected the Pro Street 177 supercharger. Using the supplied 3-inch blower pulley and 6-inch crank pulley, the Weiand 177 supercharger produced a peak of 6.3 psi and increased the power output of the 350 to 405 hp and 446 lb-ft of torque.

Most stock engines are equipped with cast pistons, cast crankshaft, two bolt main caps, and a small camshaft, requiring you to run very low boost pressure of 3 to 5 pounds maximum. Interestingly enough, even when not making boost, the spinning rotors improve the volumetric efficiency of the engine to the point where you can maintain high cruising speeds at lesser throttle openings, and in normal driving around town, you will notice that the vehicle is much livelier even when not making boost. If the cylinder filled completely with air, the engine would have a volumetric efficiency of 100%. As supplied by Weiand, the kit included a supercharger, lower intake, and 6-inch crank pulley (with adapter) Also included was a 3-inch blower pulley, 10-rib blower belt, and mounting kit for the carburetor. For your higher boost levels (which includes all 10-71, 12-71, and 14-71 applications) in gasoline burning engines, the company recommends running a flat tappet or roller cam with a 110° lobe center line. Weiand Pro-Street superchargers represent a significant leap in technology for obtaining substantial performance gains, while maintaining drive ability and reliability. Crankcase pressure under boost conditions with a Weiand 177 blower. Weiand's 177 Pro Street supercharger kits are engineered to give you a 25-40 percent gain in power - while maintaining outstanding streetability. In all supercharger applications, Weiand recommends running roller rockers and chromoly push rods. A proper amount of boost is good—very good. This cam design provides good overall power on pump gas and also aids in engine cooling. If you're looking for a cost effective method of increasing your supercharged engine's output and improving reliability, install a SuperChiller Intercooler. 177 Weiand Intercooler. On a given size blower and a given size engine, boost can be increased by running the blower faster in relation to the engine's speed (overdriving) or it can be decreased by running it slower (underdriving). The numbers related to these blower sizes, such as 142, 177, and 256, relate to the amount of air in cubic inches that is pumped by the blower in one blower revolution. Table 1 provides this information. Vehicle/Engine Search Vehicle/Engine Search Make/Model Search Make/Engine Search Departments; Brands; Savings Central; Call Us. Everything was either new or rebuilt, but I'm getting what appears to be oil leaks from the engine. The more boost, the colder the plug required. Improved starting. These type of superchargers (or turbos) run at extremely high speeds. Save this search. 34° is a very safe figure and should provide close to optimum performance. Supercharging is an extremely effective way to reliably increase horsepower and torque, particularly in the low to mid rpm ranges where most street machines are operated. © 2017 Power Automedia. Centrifugal superchargers and screw type superchargers are called "internal compression" blowers because the air compression takes place inside the supercharger. Before adding boost, the 350 was run in normally aspirated trim using a Holley 650 XP carb, Edelbrock Performer RPM Air Gap intake, and MSD ignition system. - Weiand's 6-71 kits are the ultimate statement of power and looks. Watch; M R S F H p o M H n s Y N o T L A r e d. Weiand 6-71 Vintage Supercharger … Adjust the distributor so that the new mark on the damper lines up with the "0" on your timing tab. A legend in the industry, Lunati offers several camshafts specifically designed to work with Weiand blower kits. You can run single carb with a 250 but might not reach a high HP number with a single carb. We purposely chose the larger 177 Pro Street blower over the smaller 142 (which would easily satisfy our current power needs) for its increased capacity. Formulas have been developed that convert your static compression and supercharger boost to the effective compression ratio. So after a long winter my motor is rebuilt AGAIN after major failure (NEW ENGINE BUILDER NOW) and going on the dyno this Thursday (NEW DYNO OPERATOR ALSO NOW). However, if you never drive your vehicle in the higher speed ranges, you may be giving up impressive improvements in the lower speed ranges. Remember that at full throttle your engine is going to need about 50% more air than it did before the blower was installed. Qty: Add To Cart. So equipped, the supercharged small block produced 452 hp and 492 lb-ft of torque. Ford F-250 Eddie Bauer / Special / XL / XLT 5.0L 1995, 177 Blower™ Supercharger Kit by Weiand®. Running too small a carburetor therefore means that you can't flow enough air to produce maximum boost. 177 Weiand Intercooler. If your engine is larger, your boost will be lower. Just as the choice of heads, cam, and intake will be dictated by the intended application, so too is a supercharger. Holley "Supercharger Carburetors" are specifically designed with this feature. Minimum of a 3" diameter dual exhaust with free flowing street/race mufflers and large tube headers. The above chart shows the effective compression ratio of your engine, which combines the static compression ratio with the amount of supercharger boost. 7 S 0 P O N S O A R P A 7 E E D-1-1 U J-1 0 F J-1-1. There is also a version of the three lobe helix rotor used in racing called the "hihelix" rotor. The SuperChiller Intercooler dramatically reduces the air temperature of the intake charge, thereby increasing air density to the combustion chamber. On the big block, Weiand offers the Pro-Street 177 for good low to midrange power, the 6-71 for strong mid to high-range power, and the 8-71 through 14-71 for large displacement, high boost/rpm engines. Basically, this was a mild 350 just one or two performance steps above a stock motor or your typical crate-motor offering. Customers also viewed these products. We quickly removed the NA induction system and installed the dedicated blower manifold. To achieve these high speeds in the centrifugal supercharger, there is an additional internal step-up drive inside the blower. Intercoolers use air or water to help lower the increase in inlet air temp inherent in boost production. The blower snout featured a spring-loaded tensioner to eliminate belt slippage. NOTE: We do not recommend using these devices in marine applications. Retarding the timing under boost increases the combustion temperatures. Formulas have been developed that convert your static compression and supercharger boost to the effective compression ratio. The choice of camshaft can make or break a blower motor. And test 20 shows the power we made at maximum boost with the Weiand 177-cid blower installed. 128-177. HORSEPOWER! We promise not to use your email address for anything but exclusive updates from the Power Automedia Network. Weiand 6512-1 177 Pro-Street Supercharger Kit $3,196.83. You may choose to do this anyway because you want the look of the larger blower and are willing to give up some bottom end performance. The case of the 6-71 and 8-71 superchargers have been redesigned for a nostalgic look that will look at home on a cacklefest dragster as well as a new high end build. Next. One important thing to keep in mind with respect to Weiand roots superchargers is that throughout the rpm range, the air ratio of the supercharger is consistent with the engine displacement. The 6-71 and 8-71 designations refer to the original GMC diesel engines. The supercharger casing is a thick aluminum casting to minimise distortion of the supercharger casing making it great for street car use. A proper amount of boost is good—very good. 3. NOTE: It is important to understand that for all practical purposes, an engine does not know what size supercharger is bolted to it. One of the big advantages of a supercharger is that it can overcome many induction deficiencies in an engine, especially in the low to mid-range rpm area. The Weiand 177 blower may be small, but it is mighty. LS engine using a blow-through carburetor and a Vortech centrifugal supercharger. Pulley, Supercharger, Serpentine, Aluminum, Black Powdercoated, Weiand 142/177, Each. Usually with a mild blower cam and a larger carburetor you can expect a typical small block to produce anywhere from 360 to 400 streetable horsepower. Some are looking for that top-end rush of a centrifugal supercharger, but traditionalists want more immediate gratification. Weiand uses two types of supercharger rotors. Heck, even the name sounded old-school cool! Weiand Harmonic Balancer Spacer Kit - Ford 174 Supercharger. I may be wrong but I thought the 177 blowers were only designed to make about 8-10 psi MAX!!! If not, you won't make the boost that the blower is capable of. budget set up..ive gone 11.80s with it in a stick car at 3250lbs. When you combine the boost you are running in conjunction with your compression ratio, the result is known as the "Effective Compression Ratio." runs on pump gas Mini blower has good torque, street friendly and fun to drive, plus you can get them running pretty good at the track. Add to cart . The "mildest" of Weiand's blowers are the Pro-Street superchargers, which are set to produce from 5 to 7 pounds of boost. You can find your static compression ratio on the left side of the chart. Brand New. This is because the blower immediately is pushing the inlet charge right into the cylinder, rather than waiting for the engine vacuum to draw the charge into the cylinder. A smaller blower can be driven at a higher speed, which will produce a substantial amount of boost, particularly at lower engine speeds. Table 4 displays a listing of Weiand supercharger camshafts for the Chevrolet small-block (flat tappet hydraulic). View Profile View Forum Posts Private Message View Blog Entries 07-19-2020, 05:53 PM. The Pro-Street 256 is a good all around compromise. The amount of boost that is being produced by the blower is the critical factor. Supercharger boost, however, is not totally constant. This shopping feature will continue to load items when the Enter key is pressed. Please consult the charts in this Technical Section and the replacement pulley section for help in determining the pulleys and blower sizes that will best suit your specific application. On a street vehicle, this typically occurs for short periods of time. At very high engine speeds, the larger blowers will produce substantially more power than the smaller blowers. All of these figures are based on a blower that is producing about 6 or 7 pounds of boost. These devices usually operate on a "degrees of retard per pound of boost" and are typically adjustable from 1° to 3° of retard per pound of boost. Bolt-on 75 to 150 horsepower. The basic design of a Roots supercharger has been developed over many years and has resulted in a highly refined product offered by Holley under the Weiand brand. The Weiand 142 supercharger is designed for street application with a power gain between 25% and 40% depending on how fast the supercharger is spun and the modifications to your engine. Plus, the 110° center line provides even sharper throttle response and helps lower initial cylinder pressure (you won't miss the cylinder pressure with these blowers, since they make plenty of boost). After you mark off 34°, start your engine and rev it up to a speed where the entire distributor's mechanical advance will be in. With one of Weiand's superchargers, here are some of the improvements you can expect: 1. Due to the restrictions in any engine created by the air cleaner, cylinder head and cam timing, all of the air that should get into the cylinder can't, so the typical engine's volumetric efficiency is less than 100%. In marine applications the engine is usually in full boost all of the time. These highly sought after superchargers have been unavailable for years. This puts additional loads on pistons, rings, bearings, crank, rods, and cylinder walls. The compression ratio that is built into your engine is called "static compression." Though better than their stock cast-iron counterparts, the GM aluminum heads were far from racy and combined with the dished pistons to produce a blower-friendly compression ratio of less than 9.0:1. Part# 90683. Higher boost pressures will require lower compression ratios or a boost retard. If it were even possible to gear the blower so that it would spin fast at low engine speeds, it would then make too much boost at higher engine speeds. I made 391rwhp 406rwtq at 5-6lbs of boost with cast heads and hyd flat tappet cam. This picture shows the width and measurement of a Weiand 177. But, it's small size also means that it can't make as much boost as its larger 71-series cousins. Whether it’s for looks, cooks, or a little of both, adding a roots-style (positive displacement) supercharger to any motor is a surefire route to increased performance. Conversely, as engine size goes down, boost goes up. boost gauge, if desired, before installing the manifold on the engine. Capable of flowing 1250cfm, Torqstorm Superchargers® are able to support over 700hp individually, and over 1200hp with our Twin Supercharger kits!! See our additional drive ratio charts at the end of this section. Conversely, it is not practical to run a small blower on a big engine, because you would have to turn the blower so fast to make a reasonable amount of boost that the blower would become very inefficient, particularly at higher engine speeds. This is compounded by the lack of what we call secondary intercooling. The company was active in producing manifolds and drive systems for adapting GMC diesel superchargers, such as the 4-71 and 6-71, followed by the development of its own superchargers that are completely manufactured by Weiand (including 8-71 through 14-71 models). Weiand Pro-Street and 6-71 superchargers can be installed on a stock engine, as long as the static compression ratio is 9:1 or less and engine speed is limited to 6,000 rpm. As always, there are limitations to the available rotor speed and attending boost supplied by any blower, especially the roots style. $4,604.67. It is actually an air pump. It is worth noting here that roots blowers are much more efficient at lower boost pressures. With 6 lbs. For more information on Lunati's line of blower cams, consult the Lunati section of this website, or call Lunati and speak with one of their cam experts at 901-365-0950.

Now that supercharging is becoming quite common on stock factory vehicles, more people are realizing that a supercharger is a safe, practical source of performance increases. Depending upon how well your engine breathes, the amount of observed boost on a gauge can vary substantially. 177 Weiand Intercooler. Our acclaimed editorial staff covers all aspects of engine and driveline upgrades with a mission of presenting information that is both interesting and achievable for the “average car guy”. The 350 had previously been upgraded with a mild PE246 cam from COMP Cams. One important thing to keep in mind with respect to Weiand roots superchargers is that throughout the RPM range, the air ratio of the supercharger is consistent with the engine dis-placement. Billet belt tensioner components and V-belt pulleys round out the package to give you everything necessary for installation. If it is lower than this, you can run more boost. As a result, these units typically do not produce much power at low engine speeds because the impeller is not spinning fast enough to make much boost. The compression of the inlet charge (creation of boost) actually takes place in the cylinders and the manifold. This requires purchasing additional optional pulleys. To some degree, this can be controlled with boost retard devices, but we do not recommend that you set up your engine and supercharger to provide more than a 12:1 effective compression ratio.
