ABOVE IS THE CONTROLLED INDUCTION 2020 "MAIN FORM"
All of the calculations for the camshaft requirements are accomplished here. Most of these input values are basic knowledge, supplied by the component manufacturers or physically measurable. After entering your engine data, you simply click on three buttons, or follow the step by step instructions that will guide you in determining the correct values to enter for "Throat Boundary Layer", "Max Allowed Throat fps", "Mean VE%" and the "Curtain Velocity Adjust".
>>>>>>>> All parameters have individual pop up help with descriptions, explanations of use, and acceptable value ranges for input parameters.
THE PROFILE PART EDGE DRAWING FORM
NOT MUCH TO THIS. AFTER CHECKING THE MINIMUM RADIUS ON THE GENERATION FORM, YOU CAN SELECT "DRAW PROFILES" AND THIS FORM WILL APPEAR AND DRAW YOUR PROFILES. YOUR LIFT TABLES CAN BE DRAWN AS FLAT TAPPETS OR ROLLERS BY SELECTING THE INDICATED BUTTON AT THE TOP, CENTER OF THE FORM. THE NOSE RADIUS VALUES FOR THE FLAT TAPPET PROFILES WILL ALSO BE CALCULATED AND DISPLAYED ON THIS FORM.
ANYONE CAN DESIGN THEIR OWN CAMS AND GENERATE PROFILES WITH CONTROLLED INDUCTION 2020. AND HOWARDS CAMS CAN PRODUCE THEM.
Selecting the correct camshaft with Controlled Induction 2020 VERSION 1.04. It does everything except type in your engine data! It is not necessary to know how Controlled Induction 2020 works to use it successfully. You enter all of your known engine values and the peak HP RPM and use the autocalc buttons to calculate the max allowable throat velocity and mean port velocity, which will determine the VE% and mean cam design velocity, which will calculate the camshaft. However, you can still follow the step by step instructional and manually input those values to acheive the same results.
When you are finished designing your engines camshaft requirements, you can generate and save the profiles in an "S96" format, which can then be loaded into Dynomation and/or Engine Analyzer Professional software to simulate and verify your cams performance. With all of the correct input data, you will determine the correct camshaft the first time and every time you model an engine. It won't take long for you to realize how accurate this software is, and that you don't need to ask for any more cam recommendations.
ABOVE IS THE PERFORMANCE SCREEN
ATMOSPHERIC CONDITIONS INCLUDING AIR DENISITY ARE CALCULATED FROM OBS. BAROMETER, DRY BULB AND WET BULB. BSAC, REQ CFM, REQ VE, BSFC AND THERMAL EFFICIENCY ARE CALCULATED IN THE FUEL ENERGY SECTION. RESONANT TUNING LENGTHS ARE CALCULATED FROM THE SPEED OF SOUND AT THE GIVEN INLET AND EXHAUST TEMPS, AND THE TIME BETWEEN THE OPENING AND CLOSING EVENTS OF THE INDICATED VALVE AT THE GIVEN RPM. UNDER BLOWN CONDITIONS, THE TEMPERATURE AND CHARGE DENSITY OF THE GIVEN "M.A.P." IS CALCULATED FROM THE GIVEN COMPRESSOR AND INTER COOLER VALUES, ALONG WITH THE REQUIRED CFM FROM THE GIVEN ATMOSPHERIC CONDITIONS.
DISPLAYED IS THE AVERAGE, PREDICTED AND POTENTIAL VALUES FOR OBSERVED AND CORRECTED, TORQUE AND BHP.
ABOVE IS THE GRAPH FORM
NAVIGATING TO THE GRAPH FORM LOADS TWO SETS OF THE CALCULATED REQUIRED VALVE MOTION, 1 FIXED AND 1 ADJUSTABLE. YOU CAN ADJUST THE DURATION, LIFT AND AREA OF THE CURVES, AND COMPARE THE GRAPHS, OPENING AND CLOSING EVENTS @ .050" OR SEAT, TOTAL PROFILE AREA AND THE OVERLAP AREA.
THE SOFTWARE WILL USE YOUR ADJUSTED INTAKE AND EXHAUST LIFT PROFILES WHEN YOU GENERATE THE "*.S96" CAM LIFT TABLES FROM THIS FORM
Camshaft Design & Profile Generation Software

THE CAM FILE GENERATION FORM
WITH THE LOBE INFORMATION LOADED AND DISPLAYED, SELECT ROLLER OR F.T. AND ENTER THE CORRECT CAM JOURNAL DIAMETER, PRESS THE "CALC BC" BUTTON TO CALCULATE THE MAXIMUM BASE CIRCLE DIAMETER, OR ENTER YOUR OWN BASE CIRCLE VALUE FOR CLEARANCE PURPOSES, ETC. ENTER YOUR ROLLER LIFTER'S WHEEL DIAMETER AND CLICK ON THE CHECK NEGATIVE RADIUS OF CURVATURE BUTTON. VALUES WILL BE CALCULATED FOR MIN RADIUS AND F.T. PROFILE FOOTPRINT.
WHEN THE PROFILES MEET THE REQUIREMENTS, THE "GENERATE S96 LIFT TABLE FILES" BUTTON WILL BE ENABLED FOR YOU TO CLICK ON. THE SOFTWARE WILL THEN GENERATE YOUR ENGINE SIMULATION AND CNC READY FILES. THIS FORM CAN BE ACCESSED FROM THE MAIN FORM OR GRAPH FORM. ACCESSING FROM THE MAIN FORM WILL GENERATE THE CALCULATED LIFT TABLES, AND ACCESSING FROM THE GRAPH FORM WILL GENERATE LIFT TABLES FOR YOUR ADJUSTED PROFILES.
