I have some camshaft specs from cam doctor that i would like to transpose onto a spreadsheet or pivot graph, has anyone set up a free to use version?

 

The sort of graph i am after is that of two herbivorous dinosaurs eating (see below)

 

This one i just clipped from google  but ideally i would like to look at lift at 50 thous, overlap etc and input a couple of different cams data.

I haven't work out a way to get the spreadsheet to reflect ATBC BTDC etc

 

 

  

 

Pointing me in the right direction would be appreciated. Cheers Darryl

Oh for a TARDIS.

 

At a late 60's Racing Car Show, I caught part of a lecture about camshafts.  The chap had two slide projectors and could superimpose different cams on a 'bullseye' screen divided into 360 degrees.

 

He could read off the angle at which the follower lifted, how high it lifted, the duration, overlap etc:  ..  in conjunction with graphs of RPM and torque

 

The bit I saw was mainly Ford, but it taught me that most people over cam road engines.

I'm a gumby with spreadsheets, but, the little I've tried with them, it wouldn't be hard to develop a template for this.
