I am putting together an excel spreadsheet that can be used to calculate engine dynamics. So far I have Engine Dsiplacement, Engine size in CC, I have combustion chamber total and static compression ratio. I am still looking for a calulcation for dynamic compression ratio. Any other calculations that would be helpful? I am hoping to be able to create a graph for hp/torque ratings based on rpm.

For about $39.99 you could just get a copy of Dyno 2000 and have it do everything (except the DCR, you can download that one off the web).
Luckily there are a few flow bench results on the board you can use to 'dial in' the flow map on the program.
