Wwest, every single face in the room ( including the smileys at the bottom ) have a broader intellect than you.
You ADMITTED you were guessing, your statements are not only intellectually unfounded, they are the complete and total opposite of reality, despite all available evidence.
Ignorant would be one thing, but to read and come up with your conclusions is worse.
Your message of pure unadulterated lies? You should be so proud, lol

Your opinion of yourself can't possibly be this inflated?
I mean really, what are the odds that 100% of persons you disagree with have more experience than you, and yet you are the only person on earth who 'gets it?'
Impossible. You've had the wrong 'message' for years. Get over yourself.
I love when people know everything there is to know about something when they have absolutely 0 actual experience with what theyre talking about.
You idea of manifold vaccum is 100% incorrect. The prescense of vacuum in the manfold is what keeps the wastegate CLOSED in traditional systems. If the wastegate was always open under vacuum conditions, no boost pressure would ever be generated as all of that precious exhaust gas would be bypassing the turbine the entire time preventing boost generation.
The fact is, the wastegate OPENS as the desired boost psi is realized in the manifold.
This is such basic turbo operation theory im actually a little embarrassed to have to explain this to you.
Makes me wonder.......... have you EVERY owned or even driven a turbo vehicle?
The very existence of a vacuum pump on a mid 90s diesel chevy truck is only to keep the wastegate closed until desired boost psi is realized.
On a conventional gas engine (gas engines make vacuum because of the presence of a throttle plate-- diesels do not) manifold vacuum "sucks" the wastegate closed allowing the turbing to spin which of course makes the compressor spin (they are rigidly connected) which generated boost psi in the manifold.
thats all for now............... class dismissed.

I'm well aware of forced inductions benefits at high altitude,
But it is also extrapolated down to sea level. Same functionality, only slightly less efficiency.
So yes, while I sincerely doubt that 20-30% estimate I don't doubt that at the elevation you most commonly drive the engine is on-boost more of the time than an equivalent here in the Seattle area.
That's only of total time in motion. 100% of the time a boosted engine is being used for things that make engines matter, they are on boost.
Only time off-boost is coast, braking, idling, or very low-speed steady-state (43mph on a flat road).
All acceleration involves boost, and in 'mixed' driving with as many up-hill sections as down (obviously), 20-30% is a fine estimate at 16,000 ft or 600.
Your supposition of 1% is based on an embarrassing understanding of the mechanism involved (particularly wastegate operation).

"..I asked those that tune and work on turbocharged engines..."
Right, clearly no conflict of interest in that group, nor any narrowly focussed intelligence either.
Narrowly focused intelligence, eh? Seems like it ended up being Willard West that had the narrowly focused intelligence over there.
I do not "guess" if my statements are not intellectually well founded and knowledgeable of the subject matter I would not expose myself to the type of false ridicule that you so willingly provide.
Intellectually well founded eh? Not only did you reverse in your head what was actually being described on Ford Motorparts, you were certainly 'guessing' at everything else
I prever evidence... which I always had, just not recorded
I'm quite comfortable that my message gets through to enough readers to make my time worthwhile.
Glad you're so proud of spewing BS for SEVERAL YEARS!

...about the 3.7L V6 base engine, not the 3.5L EcoBoost V6. I've given you guys some rope, but I'm breaking out the scissors.

Thank you! This has gone on too long.
