Don't run from the question, just show where your facts support that 16:1 is a dangerous AF for marine app. You impressed us all with your Saleen and Cobra AF numbers (which have nothing to do with marine app) but I'm not hearing facts to back up anything relating to 16:1 in marine app. "He said, she said" isn't factual. I just want to know where you get your hard numbers to back your statement, that's all. It's not about me, my engine, SLSS, or anyone else. You made the statement.
As far as being my "buddy"...That's rich...the two of you sound like an old married couple, which is what this thread is really about. It's just bleed over from Pol. Rhetoric, and you're still just trying to "one up" eachother. I think someone here on the boards described it a while back as "dick sword fighting". :notam:
Here is a post from Bob at Dana Marine Products which discusses Dana's dyno testing of the 496 Mag and Mag HO with Dana's new exhaust system.
The lean spot was basically the same on the dyno and the water, in between 3000-3800 rpm it gets pretty lean. I'm not an air flow/fuel flow expert, but the O2 temp readings were 14.01-14.02 in that range. It gets a little better at higher RPM's, but it's still pretty high, 13.8. Both the dyno guy (professional engine builder) and our brothers at ECM felt that was too high for continued usage. Once you factor in ambient air temperature, that # could change. It's one of those things, can you run them without changing the fuel pressure? The answer is yes, but I gotta tell you, it would make me feel pretty uncomfortable if I wasn't strongly urging my customers to make the change. It's such a simple change, It would be foolish not to do it.
Wow, I can't believe I read all that (including links given) on only one bag of popcorn. LOL.
You guys are all too much. Both sides. Good entertainment.
BTW: How did AFR get pointed out as the mainstay of pollution in engines ? There is a lot more to it than that. 'Too' Lean is not always better for emmissions and/or even fuel economy. I'll leave it at that for now.
Switching topics but still on emmissions - anybody ever see what the effects of volcanoes have on our climate and atmosphere ? If not, do some research and be prepared to get intrigued.
If someone can find out a way to keep volcanoes from exploding we will be pretty well off. LOL.
Yes - I believe we all have a responsibility to be 'cleaner' than we are. Not just emmissions, but garbage and a bunch of other things.
In answer to your question

I merely pointed out that running a marine engine at 16:1 would be way too lean. From this came the lesson on internal combustion engines. I agree, it's been entertaining.
