Scoop or no skoooop

Don't worry your not missing anything....hood scoops are overrated.

 

Primarily by those without them.

 

I suppose that could pass as a working theory, but sorry, no, fail. Neither the scoop or the front air dam have a measurable impact on fuel economy in the real world.

 

Not to be a stickler but anytime you create a discontinuity in a surface like this, you get non-laminar flow, which means, the air flowing over the truck has a region where eddies are formed, and the airflow stalls. Same thing happens in our arteries when plaque builds up... Anyway, same issue with the bed of the truck, putting a cover on, should increase mileage. the air going over the truck's windshield and cab, eventually is pulled/pushed back down, and impinges on the tailgate.

Each thing like this, weight, air dam removal, scoop, open bed, lift... takes away from better MPG. You got to just hold the line somewhere. Each thing by itself seems trivial but added all together, the combined effect can become significant.

And then, there is the front-end of the truck. Very boss looking, but I imagine does a good job presenting a challenge for air to move around the vehicle.

 

Scoop looks rad! Look good, play good. Get the skewp.

 

You do know I was joking. Right?

 

I love these debates because this meme pops into play.

The Skewp does not affect fuel economy.

Aesthetically, it doesn't detract from the front end view...of course, this is just my opinion.

It was an added bonus in my EVAL considering I was not interested in an Off-Road.

 

Oh My!!!

I like it.

 

If it does, the impact is negligible or Toyota would note it in their specs…

 

Someone will install a programable one to tell dumb ass in front of you ,.... he's a dumb ass.

 

I need a marquee on my tailgate/rear window to do the same for tailgaters. lol

 

Automatic - 18 MPG
Automatic - 21 MPG (w/Hood Scoop)
Manual - 17 MPG
Manual - 20 MPG (w/Hood Scoop)

Call Toyota we have solved the MT-AT-HS problem.

 

Haha, are those the legit stats?? Logic out the window, if so.

 

Thats your opinion. I can't argue about the hood scoops, but the air dam definitely has an effect on getting slightly better fuel economy for a bone stock truck. Toyota just wouldn't install one to drive up the cost if they didn't do something. Engineers aren't that stupid. I've driven the same roads and same speeds with and without the air dam. The result is close to 1 mpg better with the air dam on the truck. You'll also get less wind noise to at highway speeds.

 

I took my Air Dam off when I installed the TRD Skid...it can't be installed with the TRD Skid plate in-place.

 

I find it interesting that in the eBrochure, every image showing part of the front of the vehicles (with the grille) actually de-emphasize the grille. If it is mentioned as part of the "design styling" I may have missed it. It's not going to be a deal breaker for me, but I'd just as well not have it honestly. Why? Because other people are going to notice it, and being the honest person I am, I'll have to tell them it's not functional. Being an engineer, I believe in form and function. Faux scoops just make me scratch my head. I don't get that, I don't get the grille, and I don't get the headlights. I guess it's a good thing I don't design automobiles.

 

There's no law that says you can't feel the way you do about aesthetics on any vehicle.

The debate will continue even when suggestions like mine are seen here, over-and-over but yet people are compelled to explain their thought process.

Yes, you can include me in this analysis...except, I'm "Pro-Skewp" being a Sport owner.

EDIT: Just to be clear, I'm not a TRD Pro owner...just a "Skewp" owner.

 

Less opinion, more fact. I watched a video made by Toyota engineers; the front air dam has a primary purpose of making the interior quieter due to reduced wind noise.

 

Well what the engineer didn't say was that it ALSO improved the aerodynamics of the vehicle.

Ask yourself, why would air rushing under the car create noise? Because it is getting caught in cavities and establishing eddies or turbulence. I'm not an expert here, don't claim to be one, but it is reasonable like an airplane wing, the air has to flow over the top of the truck faster than underneath it, so the flow streams can re-connect aft of the vehicle. Faster speed, lower pressure. So in a sense, the car or truck begins to act as an airfoil. It has a tendency to lift. That results in drag forces being generated.

The air dam to one extent or another not only reduces wind-noise, it reduces drag, the faster you drive, the more drag you'd have without one. At slow speeds, there's probably not going to be a big difference. 70-75MPH? I'm sure it will. That's my take and I'm sticking to it.

 

If I recall correctly, my original statement suggested neither the presence, or absence thereof, of either the scoop or the air dam would make a measurable difference in fuel economy in the real world. Yeah, if you spend your day at speeds over 70 mph, there may well be a 0.1 or even a 0.2 mpg improvement with the air dam.

The beer's on me.
