Way back in college we had to build such a spreadsheet for our Vehicle Dynamics class. It was for based on a Formula SAE car, but easily adapted to any vehicle. That spreadsheet had/did what you're talking about. It was awesome. I wish I knew where a copy was...maybe on my very old laptop...wherever that is...maybe in the garage...

 

I wrote some monstrosity in mathcad years ago that would produce families of curves for parametric studies of gas turbines and piston ICEs. Back then there was no google docs or cloud storage so it rests in that crashed hard drive I kept in a box collecting dust somewhere. I could change one parameter and after a few moments see how it affected the engines. That was my senior year in college. Some of my best days.

 

I "exported" the data from my latest/best dyno run using the export function of DJ's WinPeP 7 software... I think you'll be very happy to see all the RPM/HP/TRQ data presented in columns that should be easy to manipulate.. I DID NOT do AFR sensing on that run, hence the strange AFR values of "18"..... Have fun and know that there is a "lotta mo" run data files I can share..

It would be interesting to see if the change in Cshaft sprocket (or gearing) has more change in acceleration than any mod's short of the 351.
