On the technical side, the development engineer must know if his design and product execution meets specifications. Nitrous …, COMPRESSION RATIO . The equation below gives you the expected compression for an engine with a specific compression ratio … Check out the chart below; static compression is down the left side with boost across the top. Since the compression ratio was lowered to 10:1, a new piston design was required. Of the three basic supercharger types, the Roots design historically possessed the worst thermal efficiency, especially at high pressure ratios. Effective compression ratio: The approximate compression ratio when boost pressure is combined with static compression ratio. Roots blowers can't get away with the compression and boost that a centrifugal superchargers (pro charger, paxton, vortech), and turbos can. 1101 W. Rialto Ave. Rialto, CA 92376, USA +1 (310) 361-0020. The LS7 engine of the Corvette Z06 has 11:1 compression, the LS3 is at 10.7:1, and even the original LS1 engine had a 10.25:1 compression ratio. 1101 W.

A static compression ratio of about 8:1 is a good compromise for noncomputer-controlled engines running on premium pump fuel. A supercharger packs engine cylinders with greater-than-100 percent volumetric efficiency. Compression can easily be readily measured. Most engines use a fixed compression ratio, however a variable compression ratio engine is able to adjust the compression ratio while the engine is in operation. Note that for most street applications with 92 octane pump gas, you should keep your effective compression ratio below about 12:1. Assuming an engine with a compression ratio of around 9:1 running pump gas,if a supercharger gives your engine 14.7 psi of boost (another atmosphere) that will essentially double the output of your engine, everything else being equal. Due to how this is calculated, there are no units associated with this axis. All these parts were taken to Larry’s …, These engines feature a bore of 81mm and a stroke of 89mm for a displacement of 1835cc and a compression ratio of 9.2:1 … ECU is the ECU for the VTEC model of your vehicle. So how does an engine’s compression ratio affect performance? One car has a 7:1 compression ratio, but it also has a turbocharger. 10 0 obj <> endobj 7 0 obj <>stream Supercharger Compression Ratio Chart. The compressor's AE range depends upon the ratio of pressure it produces to the amount of air it can flow, and all compressors have a "sweet spot" where they function at maximum efficiency. In accordance with the ideal gas law, a compression operation will raise the temperature of the compressed output. It is to be used as a guideline in determining the proper maximum boost level for a specific application. Ring selections were also addressed, stepping up a PVD-coated top, chrome-coated second and nitride oil control. Say it is at 12 pounds of boost, what does the effective compression ratio become? 1 Power output is dependent on engine type, cooling of charge air, camprofile and timing, compression ratio etc. Formulas have been developed that convert your static compression and supercharger boost to the effective compression ratio. 23 Mount Erin Rd, Blair Athol NSW 2560, Australia +61 2 9607 2299 GM came up with a forged alloy that features a flat-top crown, then beefed it up with internal ribs similar to the LS9 piston and included a DLC wrist pin. Manufacturers test compressors to produce what are called "boost maps" -- charts that index a compressor's efficiency. … One of the substantial benefits in using a supercharger, … These compression ratios have given us the best results through industry …. Effective Compression Ratio Chart.xlsx Note that for most street applications with 92 octane pump gas, you should keep your effective compression ratio below about 12.0:1. Gear. Speed (RPM) FINAL COMPRESSION RATIO CHART. pression takes place inside the supercharger. It is perfectly fine to run a larger blower on a small engine as long as you use the proper underdrive pulleys to create safe boost levels. Below is a link to the engine math calculator …, Last year’s AMSOIL Engine Masters Competition was dominated by a pair of normally aspirated Hemi engines and now the guys at The Supercharger Store have … produced a very reasonable 9.25:1 compression ratio. Max Speed Max Boost Max Flow Max Power Peak Eff. It is a good idea to actually reduce the compression ratio of an engine prior to adding a blower or turbo unit, either by replacing the pistons with dished ones or by adding combustion chamber volume to the head.

Compression, Intercoolers, And Water InjectionEveryone has an opinion when it comes to combining compression ratio with supercharging. Compression Ratio: This chart shows the final compression ratio by combining the static compression ratio of an engine and the maximum blower boost from the blower system. Was just wondering, since the GT is a rather low compression engine, what is the relative effect on the compression ratio when the supercharger is engaged?
