Sounds like you were speaking in general. You didn't state anything regarding make/model/type. I speak from what I know- turbocharged I-4s beating the crap out of V-6 and V-8s with FI. Look for the FACTS all around you.

He clarified that he was talking about the engines being in the SAME car (Post #231). For example, if I lightly boosted a 2011 Camaro SS and you lightly boosted a 2011 Camaro LS, the Camaro SS would be faster. Of course you could increase your boost and might be able to put out more power than me, but my motor would be more reliable. But then I could also increase my boost and I would once again be faster and we both would have engines that aren't going to have very long lives.
