How many different types of engine configuration have you owned?

I was talking to a buddy earlier about how I have the trinity of induction on the drive - one N/A, one supercharged, one turbocharged. More interesting was the engine configurations of the cars that I've owned. How many different ones have you folks owned in the past? For balance it's probably best to limit this to cars that you've actually owned rather than driven.I believe I have owned the following (in cars):Straight 3Straight 4Straight 5Straight 6V6V8V10Flat 4Flat 6 via /r/cars http://ift.tt/2uUCXKK
