So, the fact that MAC claims a 12.6 hp increase on a dyno proven result isn't a fact for you? I'm not gonna bust on you if it's not, I'm just wondering because I don't know what other facts you could need.

 

lol yea a dyno is done to prove HP gains yah know. DUH!

 

sigma is like a facts machine!

 

Is there such a thing as truth in advertising?

 

OK, I actually had to do some work today and it’s interrupted my playing on the Internet, but here I am back to stir the pot one last time…

I checked out the MAC website and the description for the air induction simply says “F-150 4.2 V6 = 12.6 HP”. While the data might come from a dyno test, the advertisement does not say this nor does it give you anything specific about either the tests or the results. It leaves the use of the 12.6 HP number to active imaginations.

Before we form an opinion, lets look at a few more “facts” to be found on advertisements in the automotive market:

The Tornado claims, “Up To 13 HP More Power” for making the air swirl around and around in your intake.

The SpiralMax turbo air twister claims, “Up to 35 increase in horsepower” for something that looks remarkably like the tornado but is evidently better.

The Helix Power Tower Plus claims, “Up to 20 additional horsepower” for swirling the air after the throttle body.

And lets not forget the Jet Stream electric supercharger which claims, “Up to 30 Horsepower” for putting a 12-volt blow dryer looking thing in your intake.

The Magnetizer claims, “An EPA certified testing facility showed a NET usable horsepower increase of 5%” for placing magnets around your gas line.

Interestingly enough, the Engine Ionizer claims “Increase Horsepower Up to 18%” for placing magnets around your spark plug wires. I guess this is more efficient…

Are the advertisements true, partially true, or not true?

 

You can choose and pick which ones to believe and which one not to believe. Obviously I, nor anyone else IMO, would believe the tornado gimmick does jack crap. I've actually never even heard of the magnet thing until you mentioned it, so I have no clue what that is.

I do, however, believe that the MAC Intake gives you more power. Even if it's 1 hp over stock, it still gave me something. Do I believe that if you put a MAC Intake on any 4.2 F150 that you'll get exactly 12.6 hp's added to your power? Not at all...I think all engines vary little by little, but I do believe every 4.2 F150 would benifit from that MAC Intake vs. the stock one.

As far as just a drop-in K&N filter, I don't believe there is much if any difference in that setup.

So basically, until someone ponies up the dough to get a before and after dyno run for you (ie: stock vs. MAC), you will continue to speculate it's alleged power? Whatever floats your boat...I'm just too impatient to speculate it. My common sense just tells me: "Joey, you'd like to go to Del Rio right now and get a Chimichanga for dinner, but you're at work so you can't. So just go and argue about intakes! NOW!!!" Of course my common sense is kinda goofy at times...



manster: facts machine?!! AAHAHAHHHAAAHAHAHHAHAHAHAAAA! Thank you for coming into my forum! I like you, you just state the fax.

 

Along with Sigmas point, you have to remember what I mentioned before. Lets assume it is a 12.6 hp increase, if you have a cam, rockers, headers, and a tune. You have no idea what the test vehicle already had on it, all you KNOW for FACT, is that with this product you COULD gain 12.6 hp.

Also, they never specify what range of RPM you notice the peak (12.6) gain. As I mentioned previously, you could get your 12.6 hp, at 1800 RPMs. You then get your solid 1 peak hp, for 150 dollars.

they all work, i have all of them installed. I had to go to home depot to buy longer bolts to get 3 different types of throttle body spacers on at once. i am now pusing 364.3 rwhp. If you don't believe me come to San Diego and we'll race.

And joe, thanks dude! your gonna make me blush!

 

Good discussion (disagreement?).
I think Sigma's (Ron's) point is this:
The intake offers a "claimed" 12.6 hp increase.
Where is the data to back up that claim?
I would expect, that if MAC had proven Dyno runs showing 12.6 hp increase, they'd be glad to share such info, making it available for all to see on their web site.
Absent such data, we can all go by what they "claim".
Is it 12.6 hp? Is it 2.6 hp? I do not know.

There are countless products sold on "claims". Often times these are taken at face value and the public jumps on the bandwagin, Sometimes the claims backfire and the snake oil salesman/company get in trouble.

I am not a big believer in any simple, cheap instant hp add-on. If they were simple and cheap, they'd already be there from the factory.
In the case of the intake, they wouldn't qualify as simple or cheap.
Imagine the marketing nightmare of having to tell the owner of a 2005 F-150 that they had to wash and re-oil their air filter!

So, where does that leave ME?
Thinking I like it, it seems to make my truck run a little better at freater demand levels.
Other than that......

Well, you guys are addressing that in this tread.

 

I CONCUR!! I agree with Garrett. It ALLL depends on what you have on your truck already. If you have all that stuff-cam, headers, straight pipes, chip, or WHATEVER...and then you add a MAC intake- Yes you probably will see a 12.6 HP gain or more. Now if you do what I am doing and adding it to a stock engine/with just the exhaust setup you probably won't gain 12.6 HP

 

oh blah blah blah blah blah.

Here's what I know, and all that matters to me. I don't care who thinks its 12.6hp and who thinks its worse.

I had a completely stock F-150 (except for the stud-muffin that drove it)

my first mod was the MAC intake. My truck was NOTICEABLY more free throughout the ENTIRE powerband. My MPG is better, but not by more than 1 or 2.
It definitley feels like more than 1hp, from 500rpm all the way to redline (i'm guessing, no tach)

No, i have not dyno'd it, so I don't have concrete figures. And it's not the placebo effect also, cuz i told mysef to concentrate really really hard on what it felt like

Think what you want, lets just hold our own opinions. I agree with garrett in that yeah, i gained 12.6 somewhere in the powerband, but i'm sure the peak hp probably did not go up too much.

My favorite F.R.I.E.N.D. is joey tribianni. He's great.

 

I believe it's possible that it adds 12.6 hp. Or maybe a little less, whatever. For Sigma and some of the others, I'm sure they test this stuff on stock vehicles. If it says "up to XX hp", then the motor may not be stock, but in this case I think it means on a stock motor.

Guys,

Thanks for your patience. This thread has been a hoot!

 

My god you're killin' me!

low, stick around man, you make me a very happy person...in more ways than one

I agree with ya there Garrett, but it's like I said. Maybe the Intake doesn't give 12 hp's at peak RPM, but if it does it down low, that's a plus too. Having power all throughout the RPM range is what it's all about to me.
