Hi, this is my first post here. I have come across this site many times when looking for help and have found the most helpful information here. Thanks! I am creating a spreadsheet that you can input your vehicles Cylinders, Piston Diameter, Stroke, Displacement, HP, Torque, Size, Weight, Tires, etc.. all used together to help find your vehicles optimal performance for racing. I have found many issues that I am working with. Mainly right now is to determine a torque curve without the access to a dynamometer due to not having access to the actual vehicles in question. There has got to be a way to calculate torque data without dyno tuning. If anyone is interested in helping I can include you in the online spreadsheet.
