Calculator does not care about auto or stick. It is a mathematical formula that states it takes "X" hp to propel "Y" weight to "Z" ET. It is pretty damn accurate. It assumes maximum traction, it assumes car is driven properly, it uses an "average" number for coefficient of drag. If your chassis is not set up properly, if you do not have good traction, if you suck shifting a manual trans......well, then your results will probably suck.
