Velossa Tech Big Mouth?

[Msfitoy]

Neither the AfE or the VT does that, not even in combination. If your hood is fluttering at highway speeds something is damaged already or modified in a bad way. Especially if you are getting water blasted under the hood. As for 'blocking the radiator' let's acknowledge that's not what is in front - it's the intercooler and the VT doesn't block it, even my thicker CVF intercooler.

I see S&B decided to copy Velossatech:

$100?!?!...

If your hood is 'fluttering' under any condition you've got problems that need to be resolved outside of intake mods.

I don't disagree I am looking at the latches and adjusting the bumpers. But running 70mph between Charleston SC and Viera Florida, the flutter is all but gone after removing the VT big mouth. I had the VT on for over two years, I am willing to bet (in my case) that it may have contributed to wear and tear.

Running through those big southern rainstorms, water enters the VT and makes a nice splatter pattern above it show casing where it's putting pressure and inducing water potentially. Key word potentially, any front end scoop has the potential to do that. Heck my 85/86 F-150s feed from the grill too.

If the hood remains sealed then effectively the VT scoops air and the seals on the hood create another tube directing the air into the air box intake.

I want to scan this and make a 3d printed connector. That combined with the VT and SBE airbox would give a continuous tube from the grill to the airbox.

Now, let's address something you said before. The VT does block the radiator not the intercooler. It sits on top of the intercooler directing airflow through the radiator cover into the space created by the hood. This is why your big chunky CVF intercooler is not impacted by the VT intake. Above that area there are holes in the hood. I plugged these (red arrows. The blue mark is where I was getting water splatter.


If fuel economy is what people are after I get between 1.3 and 2mpg more when I use ethanol free gasoline. Sometimes the price of E0 doesn't justify the MPGs.

One more deal. I think Ford did acknowledge there was issues and did the design change but we cannot mimic that on the 5g. If you look at the 6g the intake to the airbox is a straight shot (like the S&B) but the area where the grill intake is like the VT is directly in line with that new air box intake where on the 5g it is offset. Our best bet with the 5g to mimic that would be swapping a 6g front into a 5g truck. 80's and 90's model F series trucks were similar enough to do something similar with many parts. Potentially the 5G could too.
