Intake Length Calculator

22nd February 2004

The excel source file is provided here: - Car/intake_exhaust/intake_exhaust_calculator.xls

A trend line has been added to each rpm and the y = mx + c values are found on the right. The values are then used to perform simple calculations for the user. All the user need to do is to download the file and enter whatever inlet valves degrees the engine close when piston is at bottom dead centre.

The trend lines are light coloured and thin cutting across all original lines from the original chart.
