2021 TRD Sport Premium vs 2021 Limited

The OP got the Limited

 

Each box of eucalyptus flooring was labeled 85.5 pounds each. Plus some other equipment and just did the math.

 

Lets recap and see what we’ve learned thus far shall we?

You are under the delusion that fake hood scoops on underpowered mid sized pick-ups are the bee’s knees and that pulling ugly women makes you some kind of Don Juan.

Tell us, are you one of those swarthy, hairy chested types, that wears outdated disco shirts half open to show off his multiple gold chains, and says “My friend” a lot in conversations with strangers?

 

Yes, it does. But you wont be seeing any effect for a modern injection engine. It works to some extend with carbureted engines and things that can go very fast. The only non-racing application for an injection engine is airplane engines, mainly older prop engines, modern turbo prob engines still benefit from scoops but the engine has a turbine-like booster (similar to a very complicated supercharger that has its own combustion chamber) as well.

Below is the calculation for a carbureted racing engine from the given link.

https://www.enginelabs.com/engine-t...-scoop-speed-with-a-forward-facing-air-inlet/

As an example, we’ll assume a carbureted mountain motor of 700-plus cubic inches. Note the following:
​

1. 1. Engine air demand of 1,600 cfm at 8,000 rpm
   2. Air scoop frontal area = 55 square inches

Rounding up to 48 miles per hour as the Critical Air Scoop Speed — below 48 mph, there will be a small vacuum in the air scoop. That vacuum will increase the float level in a carburetor, which may cause the engine to run richer.

At 48 mph, the pressure inside the scoop is equal to atmospheric pressure. Fuel delivery is correct for the atmospheric air pressure.

Above 48 mph, there is positive pressure in the air scoop, and the pressure increases with vehicle speed. The pressure may reduce float levels in the carburetor, which in turn, may make the engine lean out.

To a certain extent, the carburetor venturi will compensate for increasing amounts of air going through the air scoop from increasing speeds. However, an adjustment may be necessary with higher air scoop pressures, if the demands are beyond the compensation range of the carburetor.​

 

I get roasted for saying it’s pointless but this dude goes unscathed?

 

These people have scoop envy. Just look at large number of them in the BUY/SELL/TRADE section wanting to swap for a Sport hood.

 

I got a Limited back in 2017 because I was coming from BMWs and wanted the options that come standard on the Limited. I also didn't know, at the time, that the "Build your own" feature on the Toyota web site doesn't necessarily show you all available options. It does some filtering based on inventory available in your area. It looked like some options weren't available on other models. The were, but there were no trucks in the area inventory with those options.

It's now almost 4 years later and I've gone to coilovers, a 3 leaf AAL, 17" Method wheels, and skid plates so I'm better equipped for the trails I've been doing.

If I had it to do over again, I would get the TRD Off Road or just pay up for the Pro since its loaded with all the options I wanted.

That being said, you should buy what you like. Sounds like the OP did just that. All the aftermarket stuff bolts on to pretty much every model anyway (there are differences in some things like the rear axle in OR/Pro vs the rest) so in the end if you customize the badge on the truck doesn't mean much. You can even get lockers for the non OR/Pro models for a few bucks.

Drive what you like.

 

Like it or not, the scoop is in a low pressure spot on the hood, it never really gets direct airflow into it. If it where real......
