..and since it suprised me a bit. here's a shot of the inside of the stock intake tubes (sections still in place with new intake), both sides feature the same design.

Nice gains.... wonder what 93 oct would do for those numbers!

I was just stating that that was what a Ecoboost certicfied tech said, not a random ford tech. I did not say that I agreed with him or thought he was a genius or anything. If you see any of my other posts about the TSB I always state that this doesn't change my mind about tuning as I have tuned many trucks and haven't had problems and they weren't able to be traced. I also ended with the "I still wanna mod mine".

I really want to see it in black

Very nice.

I had seen pics of those vanes on another site. That's right before the turbo's, right? If so, they are Inlet Guide Vanes (IGV's), meant to pre-swirl the air before it enters the wheel. You could want the swirl to go with rotation or against, depending on what Ford was attempting to do. Either way, they're meant to make the compressor curve better match the engine needs.

Now the weird part. . . a guide vane will typically take an airflow that is straight (no swirl) and spin it. Those vanes appear to be installed backwards from what would make sense. They appear to take a swirled air flow and straighten it. As a side note, a couple of people have attempted to install IGV's on turbochargers and found that the drag losses were greater than any gains they might have had. Who wants to be the first to cut them out?

those vains were at the tube roughly 2' from the turbo, top section of the piping. I didn't pull it off all the way, so not sure what is at the other end, though the piping goes down to a rectangle pretty much on both sides, so i'm sure it's not that smooth anyhow.

DTM - my comment wasn't directed at you exactly. Just seems that in the past month there have been a dozen or so people who have talked to some form of Ford Tech, and have gotten several different responses. Just seems that those die hard mod=no warranty people would see it all depends on who you talk to. sorry if there was a misunderstanding.

sorry it's so crappy, but quick vid after leaving the dyno on the way to the gas station. windows up from a stop.

No problems. I probably should have just not said anything about it until a tuner came out anyway. Nice video, keep them coming.

I took mine pre-swirl's out when installing my Injen intake, there is no cutting involved, they just pop in and out.

hey guys, don't remove the guide vanes. they are there to straighten the airflow. these vanes are there for a reason. in a nut shell, airflow requires the equivalent of 3 duct diameters to "straighten" itself out prior to entering an air measuring device (AF sensor) or fan (turbo). if this can't be done, guide vanes are used to assist it. I noticed them last night when i was installing my Injen and said "damn, that's great! i've got guide vanes in the pipe feeding the turbo's! Very clever!"

as far as the dude wanting a picture of a black set, i'll get that shortly.


EDIT - airflow actually flows better in spiral & oval pipe, as airflow has the natural tendency to rotate in a circle as it moves downstream. after looking at the pic, it's obvious these are designed to assist that rotating process as well as straighten it. if there are vanes just before the turbo's those would be be there to strictly straighten the airflow.

pics as requested. install was a snap. very high quality stuff too. this is my first Injen intake and was impressed with the quality of materials, ease of installation and fit.
