The 930 has a Drag Coefficient of 0.4 according to this 1978 Porsche 930 Turbo - Porsche - Get Car Specs - Car specifications with thousands of models from all car makers

Frontal area is going to be between 15 and 20 sq ft, at a guess.

My 930 does 60-120mph in 6 seconds dead



The run was with stock wheels and stock 4 speed gearing, engine is roughly 500bhp, i weigh about 190lbs, and car weighs around 3000lbs with fuel. Does that add up with the calculator? I've tried playing with it but can't seam to get anything out of it.

Thought as i can give you some actual figures you may be able to test it
