In my defense, that 13.5:1 figure comes up A LOT in both Google and thread searches…I just didn’t read far enough through those threads to catch where it was debunked
Re: that 220whp idea, I’d bet that will be pretty obtainable with a header and an E85 tune. If that’s your goal you should be in good shape staying NA. I don’t want to touch the exhaust and am looking for more like 260whp to match the 981 Cayman S’ power & weight, so I’m still pretty sure I’ll go FI if I get a new Twin.
