Bit the bullet and bought the Airaid intake system specifically made for the Boss mostly due to their statement of a 19hp improvement without a tune. I spoke with them prior to purchase to confirm their statement and was told that was accurate I just got back from the dyno and for $507 the 1.3hp gain is a little expensive. Here's the dyno sheet with 4 runs.




First 2 are baseline with black key and factory cai. 3rd is red key with factory cai and final pull is red key with Airaid intake system. Ten minutes elapsed between 3rd & 4th pulls Disappointing to say the least. Guess what's being returned tomorrow?
Image is a little fuzzy but HP on runs was 396, 392, 396, 397 with torque of 355, 356, 356, 356.

 

Thanks for the data. Can't say I'm surprised, I would doubt any claims of 19HP from a CAI w/o a tune.

 

I was hopeful especially when I called and asked and they said yes it was true. Someone had to be first I guess.

 

Bummer.

 

Big time let down. Car did well on the dyno just as others have reported.

 

This is very interesting..... I have heard from VERY reliable sources that this intake was legit in it's claims. I wonder if your car didn't have enough time to "learn" the new intake and adjust itself accordingly... By your initial post I take it that you did all those runs the same day and just swapped out the keys and CAI while on the dyno?

I hope Airaid pops in here and comments on this..

 

Darn, I was really considering this, even if it was just 10hp,

 

I wasn't aware of any time limit before the hp kicks in. I put about 200 miles on the car with the red key and Airaid over the past 2 days. Varied speed, mostly ran it hard, city and highway driving. Drove it to the dyno with intake system installed, removed and installed factory upon arrival. Put down 2 pulls within 10 minutes, put in red key and pulled again within 10, swapped out intakes and final pull 10 minutes later with essentially no difference in max hp. But if it needs more time for the computer to adjust to the intake then I'll gladly put another 500 miles on it over the next couple of weeks and dyno again.

 

There is no time limit before the HP kicks in....more of a learning curve to operate correctly. You didn't mention all that other stuff in the original post.....hence the reason I asked. It sounded like you drove to the dyno did some stock pulls and then installed the intake for the first time on the dyno... Like I said I hope Airaid will chime in here... By chance did you ever dyno the car completely stock before you ever put a single mod on it?

 

Dang. Thanks for taking the time and $$ to be the guinea pi...err, pioneer!

 

I'm still wanting to see the HP gain and like the product and am willing to "teach" the Boss.
This is the first performance mod other than disc removal Car is 6 months old with 6k miles and first dyno.

 

That is pretty lame as i have seen GT's dyno 8-10 rwhp with the Airaid and no tune.

 

200 miles should be plenty of time for everything to settle in... You should be seeing all the benefits now of the intake, which you are not. Thanks for investing time, energy, and money into this.

 

I'll still chat with Airaid this afternoon. I know they just got the trackey tune and will be testing their car. If there's something I'm missing I'll pass it along.

 

Thanks for spending the time and $ to test this.

Thinking about it, it does make sense. Ford is paying for 2+ hours of CNC porting on each cylinder head on the Boss. It would be kinda silly for them to put a restrictive air box on it that cut 19 hp.

 

My thought exactly but had to check it out just in case it did work. If it doesn't work out then I'm out the cost of return shipping.

 

Agreed. No reason for a bunch of very smart guys to leave this much power on the table.

 

Terry - Looking back through your posts I didn't realize you tested the stock intake first... I thought you tested the Airaid first as it had been on the car when you pulled it into the shop... This may be why you didn't see any benefits??

I am not a dyno expert so maybe someone with more knowledge and experience can chime in here to see if there is any reason for the dyno graphs and results posted....

 

So Adam, just curious why you would think the order of testing would manipulate the test results? And I realize here that you are not a dyno expert but why would you think testing the AirRaid first or second would influence the results?

That would be like putting your car on the dyno, making a pull with the black key and then making another pull immediately afterward having restarted the car with trackkey. Other than the under-load heating the engine may have experienced during the first pull, which if you want leave the fans on the car for 10 minutes between runs, what’s the difference?

The dyno graphs and results posted show no gain. What is to be explained??

 

I spoke to 69mustangman. The car will be going back to get re-tested with the proper procedure.
