Select the correct camshaft as soon as you purchase Controlled Induction 2016 and Controlled Induction 7.08 together in our "Bundled CI" package.  You get both programs for $59.95, and together they will model all engine types and calculate their camshaft requirements.  Information on both is displayed below.   

Controlled Induction utilizes the only true mathematically correct cam requirement equation.  It calculates the valve motion requirements and camshaft profiles for any given engine combination and RPM.  The cam equations which power the software have been successfully designing cams and generating profiles for race and championship winning engines in most every type of racing for almost 50 years.  The software is easy to understand, and there is nothing as accurate, or versatile, in determining an engine’s camshaft requirements.  

These equations will model a 1 cubic inch cylinder to a 2036 cubic inch 12 cylinder, and accurately calculate their camshaft requirements.  The software is easy to operate and supports naturally aspirated, turbocharged, supercharged or nitrous engines, 2 valve or 4 valve, using pump gas, methanol, E15 or E85 fuel, with the option of a mech-roller, hydr-roller, or a mechanical or hydraulic flat tappet camshaft.  

Controlled Induction’s results offer a detailed view of your required valve motion and/or camshaft configuration.  It will compute and display intake and exhaust values for seat duration or advertised duration at .014”, .016” or .018”, duration @ .020”, .050”, .100”, .200”, .300” and .400” at the cam or valve, gross cam lift, net valve lift, lobe centreline angle, valve lift at TDC and the profile’s flat tappet footprint diameter.

Controlled Induction allows you to graph and compare the calculated valve motion requirements against your own designed valve motion profiles.  The graph screen displays calculated values for each profiles total area, overlap area, lift at TDC, lift at max piston velocity, opening and closing events and duration values for .050 and .200 cam lift.  Controlled Induction will also save all valve motion lift tables to file, for use in other software. 

If you build engines, professional or otherwise, this software is an invaluable tool.   
There is nothing more accurate in selecting the right camshaft.

Camshaft Design & Profile Generation Software


The potential VE is the theoretical gain in cylinder pressure created by a specific intake charge velocity.  The maximum velocity of the intake charge will determine the available or calculated potential VE.  As the theory goes, the maximum velocity of the intake charge will be sustained by the columns inertia and the positive affect from tuning lengths.  However, achieving the suggested VE is contingent upon the ports ability to supply the peak piston CFM demand, and having the average port area required to deliver the suggested Volumetric Efficiency at the mean and max indicated port velocity.

The intake port should be able to flow the amount of CFM demanded by the piston, when the piston is at it’s maximum velocity (plus lag time).  So, at the max piston velocity crank degree, the valve must be at, or above, where the port flows that CFM demand.  If the port does not flow the CFM demand, an increase in VE can still be gained, but the amount will depend on the available port flow. 

Every formula for potential VE lacks to mention the cam in the math, while the correct cam duration and lift for achieving the specific port velocity is assumed.  Controlled Induction software has combined the camshaft equation with the Potential VE / Piston CFM Demand formulas, and will accurately calculate the required camshaft that will dictate the port velocity that will produce the desired potential VE.  


Displayed above are the CI 7.08 "Performance", "Graph" and "Fuel Energy" forms.  

Both software models naturally aspirated, turbocharged, supercharged or nitrous, 2 valve or 4 valve, pump gas, methanol, E15 or E85 for fuel type and Mechanical Roller, Hydraulic Roller, Mechanical or Hydraulic Flat Tappet camshafts.
