That is how your engine regulates power output. Since a/f ratio is not a variable on a gasoline engine, you have to regulate airflow. That's the main reason they are so much more innefficient than diesel. So if you add more air, you HAVE to add more fuel, you'll run lean. No increase in economy there.

 

man dude can you figure out that the engine can go off tables in the pcm to make up for the air in an engine under certain circumstances. do you actually think that the engine cannot make changes to the fuel for air? i think that is why marc is not answering all of this. evedently you no clue how an engine and pcm,s work. no sense in arguing with someone who has no clue. and it doesnt take physics to understand it.

 

I don't think YOU understand that when it makes up for the added air, it leaves you in the same position you were before. What's the benefit, if you add more air? The engine adds more fuel to compensate, so what's gained from that? You speed up for one thing. But that doesn't help economy. You have to let off the gas, and what does that do? It restricts the airway via the throttle body. So it's a moot point. Evidently you aren't listening to yourself. You're saying exactly what I've been saying. Of course it can make up for the extra air. It does so by injecting more fuel!!! Why can't you understand that it takes you back to where you started from?

If you suddenly added a supercharger to your truck while driving down the road, you'd have to let off the gas to maintain speed. Does that mean you get better economy? NO!!!!! Cause when you let off the gas, you restrict the airflow, and you end up with the same ammount of air in the combustion chamber as before!! And the same negative pressure as before!! And your engine works just as hard to get its air as before!!!!!!!!!!!!!!!!!! And the only difference is that your engine has to turn a supercharger too!

Just sit and think about how your engine gets its air at part throttle. You can't just give it more air, without more fuel. And if the aftermarket intake lets the engine "get air easier" its just the same as pressing on the gas, which, in effect opens the throttle body and "lets the engine get air easier". Right? No increase in fuel economy there!!!

Read the part I underlined and explain to me how you think THAT gives you better fuel mileage.

NOTE: I just edited my first post in this thread. My statement was not accurate. Marc, was talking about the engine getting more air and going lean, and I was arguing that the engine should adjust for the extra air. I made it sound like it didn't get more air at WOT,and that was not what I was arguing.

 

Guys, chester is set in his ways and HE thinks HE'S right so just forget about trying to tell him any different!

 

Yeah theres no correcting him on this one. The dyno didnt lie to me, nor did my 1.5mpg increase.... but w/e!

 

i am listening to myself. as more air is coming to the engine and more fuel is added the pcm will calibrate it to the optimum thus giving you more power and not having to push the pedal down as much to get the same result. i didnt buy an air intake for fuel mileage it is a performance part. i got it for performance. and adding the correct tune for it to be able to make more power during all rpm's. the by product of an optimal running engine tuned for the mods will be fuel mileage. i do listen to myself. and having tuned ls1 engines in the past and seeing dyno results i know it works as well as many others. the problem is your inability to put this all in contex and just wanting to argue.

 

maybe he's just repeating what his physics teacher is telling him?
as far as dyno's not showing part thtrottle improvements- thats just plain bs-even in my configuration- mike was surprised in my part throttle tq readings while he was in it on the dyno

 

" And I loved all the plumbing equipment and fittings jingling around while I
was backing it on the dyno"........

 

I didn't say anything about a dyno. I didn't say it didn't help top end horsepower. I said it didn't increase mpgs.
ok, but that doesn't help fuel mileage.
I am not arguing about horsepower. I am trying to argue about fuel mileage but some people are too thick to stay on topic.
HELLO!!!! We've been talking about fuel mileage here!! NOT HP GAINS!!!!!!!!!!!!!!!!!!!!!!!!!!!
Um.... FUEL MILEAGE???!!!

I hope somebody here can read. I don't know why grown men have to resort to making fun of me instead of listning to what I say, and actually responding to it with a relevant response. There are a lot of immature people here. And the fact that you can't even remember what we're talking about frusturates me to no end.

 

maybe you are the one to thick to understand.

 

dude,
chester, alot of people here who have air intakes are reporting increased mpg.( more than 95% of the members)Have you ever stopped to think maybe your stubborness is to blame. True I have not seen mpgs mainly cause I keep my foot in it to my exhaust! But seriously though, Have you ever considered the other side of the story. When you get over your thick headedness look me up!

 

How many people have claimed mpg increases with tb spacers, turbonators, magnets, etc... MPG is very subjective. That's why you have to have physical proof. But whatever.

 

Soooo.............. what do you guys think of the K&N OR AirRaid CIA? I was wondering if any has the AirRaid with the Troyer tunes, that's what I'm considering.
