3. Major New Features for v4 0 Plus Version also in Cam Grinder Version The program can now use most any radius pointer for measuring a cam for doing the Virtual Follower analysis This means that you could measure a cam with the 750 diameter Universal Roller and then correct to what it would be with a 800 or 700 diameter roller You can also correct to something really different like the exact cam profile as ground like you were measuring the cam with a knife edge pointer An additional advantage of using a follower instead of the encoder probe directly is no side loading is put on the encoder probe thus avoiding possible damage Figs A44A A56 The Virtual Follower screen can now be enlarged for analysis in greater detail Fig A56 You now have 2 options for Analyze option at the graph screen Just show the max difference between lobes or show the difference between the lobes at all data points Now the program draws the actual profile lift like the profile was measured with a knife edge pointer on the Virtual Follower screen in addition to follower lift The program draws this in green and made the text boxes green which relate to this measurement Fig A56 Cam Card now has options for printing printer setup including a lobe from a different file for either an intake or exhaust lobe if the cam you are currently reporting has only Intake or Exhaust lobes or including the Company Logo graphics file on the card

Camshaft Reference Handbook has developed some limits which should be avoided for various valve train design These are Valve Train Type Direct acting OHC overhead cam buckets valve trains OHC rocker arm valve trains Pushrod rocker arm valve trains The program offers to do FFT analysis of the Lift and Jerk data as well However we don t know of any limits which have been developed for FFT analysis of these curves You should get a copy of Don s book for more details The procedure to do this analysis are outlined in Figure A62 and include e Obtain a cam file and convert to Measured with Electronics If you measure with our Cam Test Stand this happens automatically e Enter data for the Primary Valve Springs which is typically the largest spring outer spring in a valve spring pack via the Cam Test Setup screen e Seta description for the Valve Train Type in the Primary Valve Spring screens also e Request the Valve Accel Frequencies Data Type and set Graph vs Nat Freq RPM to Yes e Make a graph and find the lowest frequency RPM which goes above the limit set for the valve train type The frequency RPM below this is the safe RPM limit for this particular valve lift profile with these valve springs IMPORTANT This analysis is done on the Valve Acceleration curve Therefore it will change depending on the Rocker Arm Ratio and Lash you enter into the Cam Test Setup screen C Performance Trends Inc 2012 Cam Analyzer
