"Well, a TBS essentially lengthens the intake runners. This gives the air/fuel more time to mix prior to entering the cylinder." That is what was stated, what he didn't recognize that is not what the TBS is meant to do....The TBS INCREASES the air flow using the grooves inside it to speed up the air going into the intake.

Also, I completely agree that any vehicle pre EFI would benefit much more than an EFI vehicle.

Thanks for the contacts and the help, as we all are trying to get the best performance out of our trucks and knowing experienced people on those topics helps out a great deal.....even if some don't like the TBS ha
Thanks for the

 

I've got a post a couple notches down about a knocking under the dash.....you guys have any input? I have no clue where to start.

 

Right back at you (and from organizations that have nothing to gain by selling or advertising these):

Gas saving devices that promise increased fuel economy



Looking For A Miracle: We Test Automotive 'Fuel Savers' - Popular Mechanics

 

I have nothing against them - except they are worthless on our engines and don't want others to fall into the same trap.

 

So let me get this straight......you think that increasing the Air Flow does NOTHING to an engines performance? Wow....check this link out How to Gain More Power in My Truck | eHow.com



Increase Horsepower: Air Induction

Air induction is the air flow into the engine. Increase the air flow and you'll increase horsepower. Start with low-restriction air filters from K&N. Their standard filter promises a 1-4 horsepower gain. Upgrade to a high performance aluminum tubing intake system, and that jumps to a 7 horsepower gain.

Another way to reduce restriction of air flow is by increasing the size of the throttle body (for fuel-injected cars). JEGS also carries a flow booster, which directs air towards the throttle body and promises to give you another 7 horsepower. For carbureted cars, go for a larger carburetor. Performance Carburetors offers expert advice on which parts you'll need.

Better yet, find me something that says an increase in air intake hurts my vehicles performance of hp, torque, etc.....

Also, I never argued the fact that the "TORNADO" was crap, Tell me if popular mechanics found that a throttle body spacer that increases air flow has no effect and i'll believe you.

What your failing to see is that no one has argued the functionality of the AIR RAID system. The "tornado" had restrictions and dissproved, the idea of airflow into the engine was NOT. Therefore leaving that product infallible. NOT the idea. SO find me something that says increased airflow into the engine is bad and that my AIR RAID is as well and I will thank you for saving me money. Don't find me OTHER products that aren't as good.

 

 

"Increasing horsepower is largely about increasing air flow. Think of your engine operation as a continuous circle: air flows in, mixes with gas, sparks in the combustion chambers that power the engine, then flows back out through the exhaust. Anything that makes that air flow more freely helps that circle spin faster and more efficiently. You gain horsepower, and waste less gas."

 

You are right on some points, but you are missing others.

You can put a 5 gallon bucket sized intake on your truck if you want, but that doesn't promise you more volume or air speed. Not to mention that the stock parameters of the truck will only recognize so much of an increase in the volume of air before it just becomes a waste.
As I said in previous posts, your TBS may be beneficial, but only after you've changed a number of other parts (like you said, air in has to get out somehow) and you've changed your stock MAF along with tunes optimized for the newly found volume of air you're attempting to cram down its throat.

The TBS alone, with no other modifications, is likely to gain you nothing but a lighter wallet. Much like a CAI without other mods.

 

Sorry guys, i tried to tell him earlier but he is a bit hard headed when it comes to big brotherly advice...at least he listened to me when I told him to seek the advice of FTE! Thanks again guys, we'll get him straight soon enough.

 

To try and help you understand a few things, I'll pick apart some of the other poweradders that you mentioned.

K&N or other brand of low restriction intakes: As you stated, these intakes have less restriction (and sometimes less filtering) of the airflow. Less restriction means more air.

"High Performance" aluminum tubing: Allows smoother airflow with less restrictions. Less restrictions means more air.

A larger throttle body: Upgrading the size of your throttle body will increase the amount of air flowing into your intake. The larger mouth will allow more air to flow through.

Flow booster: The idea behind this is to smooth the airflow (less turbulence) into the engine. The more turbulence, the slower the flow of air. I don't have much experience in this product, but from what you have written I can already find a flaw in the system. Your Throttle body does not need to have air directed to it. It already has air directed to it. This looks like another piece of metal that will slow down airflow if anything.

And finally...
Air Raid TBS: A piece of metal with spirals grooved into the sides to help direct airflow. The concept is, that the grooves will help spiral the airflow and lengthen the intake runner allowing more time for air and fuel to mix. The reality is, The fuel and air do not mix in the intake manifold. It will not speed up airflow, thus it will not increase airflow.

Simply making air spiral will not help it it speed up. Nothing is really making it speed up. A supercharger works by forcing air into the engine. A turbocharger uses your exhaust pressure to speed up impellers which then force air into your engine. Essentially, hooking a leafblower up to your intake will create a forced induction system that could theoretically work. This is because an external device is actually FORCING air into the engine, hence the term Forced Induction.

Increasing airflow has a lot to do with engines performance. But most of these simple $50 pieces do not increase airflow.

That's at least my knowledge on this, correct me anywhere that I was wrong. I'm still learning too.

 

Throttle body spacers have been tested many times over and really do not work. Your engine is fuel injected. There is no atomized fuel there. Spacers are a different story with a carb. If it did so well we would all have them.

Consider the engine as a large pump. Removing restrictions to improve flow is what works best. Less restrictive intakes and exhaust, etc. However too much of 1 thing kills any improvements. It has to be balanced out.

In the days of old concerning musclecars, the exhausts were extremely restrictive.
Once you had a free flowing intake and exhaust, larger carbs were in order, then a higher lift cam and gearing.

If it was so simple, ford would have done it already for fuel economy for the masses.

 

This is BRILLIANT !!!! I'm going to put a leaf blower inline to my throttle body air box,..and control it through a simple toggle switch on the dash, and power it with an inverter. Can you say,."INSTANT SUPERCHARGER"

 

yes, both items are a waste of you money

 

wait until you run lean ('cause I'm sure you don't have a custom tune) and cook your motor

 

...and then all that pretty swirly spiraling air meets Mr Valves. Stop, go, stop, go. Poor pretty Mr. Air ain't so fast and spirally now, is he?

The claims of 1 to 4 HP (or whatever) gains are at what RPM? I personally dont care if there's a few more HP in the realm of floating valves and blown gaskets. Knock yourselves out. It's your money. I already went down that road many years ago...
