Jul 30, 2022 · A calculator to find all the necessary parameters of a camshaft. Wallace Racing BACK to Calculators Use Advertised Durations - usually at .006" If you use .050" Duration numbers the opening/close will be at .050".

Mar 22, 2007 · CamCalc. Last update: March 22, 2007. This page will generate a table of lift figures for a harmonic cam from values entered in the fields below. The lift table is used in machining the cam profile by the milling method (see Page 7 of the Feeney Construction series for a description of this process). The following links provide more detailed ....

Calculate Camshaft Overlap From Lobe Centers and Duration. 8/1/2022 05:13:29 AM PONTIAC POWER RULES ! ! ! ... (in degrees) Exhaust Duration : (in degrees) LSA :.

An interactive camshaft calculator where engine builders can see how valve overlap (and boost efficiency) is affected by a camshaft’s physical design. How to use MGI’s Camshaft Calculator When shopping for camshafts from different manufacturers, enter each of their supplied cam card specs into MGI’s Camshaft Calculator..

Keep in mind that to advance the cam you must lower the intake centreline. For example if our cam has a lobe separation of 110 degrees the cam is “straight up” when the intake centreline is 110 degrees. Moving the centreline to 106 degrees advances the cam 4 degrees. If we change the centreline to 112 degrees, this would be 2 degrees retarded..

Program imports open data, close data, base circle size, follower size, then calculates velocity, acceleration, jerk and radii of curvature for all 360 degrees. This is a universal cam analysis program that can also calculate cam lobe stress (PSI) and theoretical valve gear separation RPM (valve float) based on known valve gear mass and spring.

This means they are shooting for a particular port velocity, and regardless of the intent the camshaft the calculator assigns it. two extreme ends of the spectrum for example: a full race 289 stock eliminator combination utilizes a intake duration of 205 degrees (.050), yet a 300 cfm 289 cid street combination needs 246 degrees (.050).

. Camshaft Article. In another section, I explained how cams work, powerbands based on duration and how important valve lift is. There are two other areas of camshaft specs you need to know before you buy:Lobe Separation and hoe to figure out the duration you need in engines larger or smaller than 350ci. Lobe separation is the amount of degrees.

This is due to manufacturing tolerances in key and dowel pin locations of the cam and crank sprockets and the cam itself. It should be kept in mind that the readings taken at the degree wheel would be crankshaft degrees; camshaft degrees should be one-half this reading. Duration is calculated by adding 180° to opening and closing readings.

Degreeing Your Cam. Step One: Find Top Dead Center on the number one cylinder and set your camshaft degree wheel pointer to “0” or “TDC”. Step Two: With the dial indicator on the #1 intake lifter, rotate the crankshaft clockwise until the lifter goes to its highest point. Step Three: Set the dial indicator to “.000”.
