Worked great. The line from the manifold side was popping off so I put a little black RTV on it. No issues after that.

I think the point of his scoop is it is effective and doesn't require a Pep Boys stick on scoop with a hole cut into the stock hood. I'd much rather have something that is a clean "non cutting" install, inconspicuous (or dainty as you put it) and effective.

Plus removable!

That's a plus as well, but I can see it leaving a mark of some kind over time.

No reason I can think of it wouldn't work.

be careful where you place it
You might not realize it but there is not a lot of air rushing up that hood. We did some extensive air testing with yarns taped to the entire hood and drove around. Watching the yarn there is really no volume of air on the surface. We made little stand offs with welding wire and got the yarns up at 1" and 2" off the surface and found air volume. We also had to make the scoop come fwd at least 5" from the end of the hood to get air flow. Back by the cowl is pretty much dead air. Its not as simple as it seems. Next ime you wash your car look at the water laying on the front bumper and around the headlights, go out and drive it at 90 mph come back and look, water didnt move at all. There is a lot to the way air moves around surfaces

my scoop leave no marks
It is held on with 1/ 16 thick 3m moulding double sided tape

bahahaha the struggle of not having a wind tunnel to test it in
I guess you go with what you got

yea ive been doing this trick since the 70s, It works very well for finding out air flow direction and volume in a crude way but it works. nascar used to put drops of thick oil all over the car and go out and run it to see where the low and high pressure area's were before they had access to wind tunnels.

hot day today
Was 95 here today and i had to go to ny. Sat in traffic for an hour, iat never went above 118. With stock air box used to 130s and 140s. Driving iat was 96, 95 oat. This thing works great

I tried to read all of this but gave up at the top of the third page.
If no one said it you might lower temps even more by removing the stock tubing from your custom air box. It pulls air from the inside fender which I think can get a bit hotter. Your scoop is amazing for anyone not wanting to drill wholes exc.
Someone mentioned a hood with a functional scoop in the center. I think this would be even better for ram air (no offense to your design, yours is great an defiantly would be a cheaper option and good for that's that have cai from a company.) I think the benefit of having a scoop in the center of the hood would be real functional ram air. U build a kit to the the intake pipe straight up to the scoop with the sensor and filter directly sealed to the hood.
**** you auto correct!

believe it or not there is not a lot of air at a substantial pressure in the center area of the hood. when we did the driving tests with the yarns on the hood the most volume of air that had any force behind it was out on the outer 6" of the hood, the center was kind of dead from mid hood back to the cowl unless you got up 6" off the surface of the hood. you would have to use a dead dolphin pro stock scoop like warren Johnson has on his pro stock. that's why those drag racing scoops are so high, so they are up in clean air where they can get some pressure. I know, I have done a couple air induction setups on pro mod cars for friends of mine

Yeah, typically it would be raise 2-3 inches to grab more air but your right I am slightly wrong in the way I explain it. It would be center width wise, but right at the front to catch the air before it gets out of reach.
I also want to be clear, I'm not questioning your scoop or testing. I'm sure it works great for you and if you produce it, it will work well for many others to.
Just saying different strokes for different folks. And what I want is a badass one in the center front of my hook for both looks and functionality.

to each his own
I fully understand. My preference has always been very stock and discreet looking but bad ass fast.

i was overview this thread and still doesn't know what is all the massing around this weird looking hood scope?
i don't want to be the bad guy or a party pooper, but this is really unnecessary.
this is a sonic... with a 1.4 liter small turbo engine.
there is really no need for such.
after a few pulls at full boost, the temp will go higher no matter what you will do.
it won't make any different, even if you will take the air filter out side the car.
and there were a bunch of tests that done this with the same conclusion.
additionally, and this is my opinion only, the scoop looks horrible on the car.

People are allowed to hold their own opinions on looks. If you don't like it that's fine, but he has already proven lower temps... And I'm not sure where you got your conclusion, because mp fab also has a ram air set up that has proven to lower temps. The heat from the engine heats up the air in the tube, providing fresh air helps bring that temp down.

Wow u need to learn something son
YOU OBVIOUSLY DONT KNOW YOUR ASS FROM A HOLE IN THE GROUND WHEN IT COMES TO ENGINES AND TURBOS
the harder you push it and the more boost you make the cooler the intake temp gets because ITS PULLING MORE COLD AIR FROM OUTSIDE UNDER HIGH BOOST,
and I have had problems with normally aspirated race cars developing ice in the carbs on a humid night because the intake temp got so cold at rpm
you need to learn something before you go shooting your mouth off
