From what I understand the car needs a little time to adjust itself after you install a major component like an intake. Same would ring true for the TK.

The OP ran the Airaid intake for 200 miles and then drove with it installed to the dyno. He took it off, installed the stock one, and put it on the dyno without letting the car settle itself to that intake...

I am not making excuses for the results. Just posting what I know....even if it may be wrong.... However I am not a pro and hopefully someone that is will chime in....

I think the best way to determine something like this is at the track. For example back in October when I was at VIR would have been the perfect time. There was a mobile dyno there. Run a session with say the black key (Having driven the car with the black key only before the event as well). Let the car cool down and put it on the dyno. Run the red key for two sessions. Let the car cool down and then put it on the dyno.

Not exactly an easy thing to duplicate but there it is..... My plan to dyno the Trackey is this:

Take the car in the morning to the dyno and have it dyno'd. Go install trackey. Drive around for about 100-150 "spirited" driven miles. Take it back to the dyno. All on the same day. The weather should be negligible at this time of the year here. It may not be 100% accurate with exact number but we should see if there is an approximate change....

 

Quick update. Just spoke with Airaid and I will be taking the Boss back in and will follow their dyno procedure. Questions have arisen about the amount of time the Boss had to learn the stock vs Airaid intake system given the amount of time each intake was used on the car. The Boss has 5,500 miles on it and is broken in. It was and is drive spiritedly. The car was driven 200 miles with the Airaid then dyno'd on a Dynojet with outside temps of 60.
This was the first and probably only Boss he'll see and as such has not had much time with the Boss' computer system and the adaptive logic and dyno'd the car as he would any other pre '12 Mustang with the presumption that if you change a part and run the car the results reported are directly related to the part. The car did put down 397 corrected hp and 356 lb ft of torque but whether this was due the intake, heat soak, cold, loaded, unloaded is not for sure.
I am optimistic about the Airaid system delivering the stated hp gain and will post the results following Airaids dyno procedures.
Thanks for your help David.

 

In for more results

 

What did he do wrong in testing?

 

I am glad to hear it.... Again, thank you for doing the tests and the money and time that YOU are giving up and then sharing your results with us who give nothing but gain everything.....

 

I echo Adam's thanks as well for leading the Boss fleet in trying out this new intake. I too am interested in the induction system but knowing how the Ford engineering team squeezed every last Hp out of the RoadRunner engine, I was a bit skeptical. They book kept even fractions of a Hp relative to the Coyote baseline during development.

Adam, I think your VIR plan for back to back comparisons certainly sounds reasonable. To do comparative testing within a short time frame so as to minimize atmospheric condition fluctuations is key. Something which you obviously recognize.

I do however believe many owners over exaggerate the PCM adaptive software logic timeframe necessary. Computers have come a long way in the last 5 years and I do not believe it takes anywhere close to 200 miles to "learn" driving patterns for engine control. I think this is owner wishful thinking hoping things change for the better.

Undoubtedly the calibration starts at a baseline value developed by Ford to be reasonably close to a "norm". And then this value (whatever it is) is tweaked by observing driving behavior by some small amount about either side of the norm built into the software. Thus I would not think big changes occur due to this learning. Emissions certification might be compromised if the learning did much to the EPA certification values. (And undoubtedly the certification efforts look at the + and - bands around the norm to assure compliance). I am told by Ford engineers on circa 2006 MOD5.4 engines that the control logic in the adaptive mode could be accomplished in 25 miles. I would think it even shorter in duration in 2011.

 

Terry,

Thank you for the clarification and your honesty!

Thanks,
David

 

We need a paypal donation to help with cost of testing!
Time to set aside and money for Dyno doesn't come easy, what were the action or procedures you followed to see a gain? Do you have graphs from your test?
Very interested in Airaid!

 

Wouldn't that be nice. My dyno shop gives our Mustang club discounts but even so this will take money from other wifey things. Last nights run was cheap, only $70 for 4 pulls. Next sessions will be $60 each for 2 pulls each. As soon as I get the manufacturer procedures I'll know how many sessions I need. I talked with the shop and he'll do whatever is needed as long as I have the money.

 

Inquiring mind wants to know... learn what? The CAI is supposed to deliver more and cooler air into the engine. What's there to "learn"? Either more air enters the engine -> more power... or it doesn't.

But I'll keep an eye out for the new dyno results.

 

Interestingly similar results on mine (stock airbox) and I know it's different dynos and different days, but my SAE corrected #s are almost identical. Must be a CO thing

Thanks cloud9. They must be twins. I knew CO was the best. Nice to know there are others with similar baselines on a Dynojet.

 

Woah woah woah......!!!!!!!!!!!!!!! Hold on there. You must be new here so I can let this one slide........ EVERYONE knows the fastest is the









SILVER!!!

 

They must be fast, because I've still not seen one

 

Saw one last week, looked great. (Parked in a local dealer's showroom w/ the hood up!)

 

Go over to BMO..... There is one at the top of EVERY page. It is there for a reason.......

 

That needs to be changed to COMPETITION orange and black. The true fast ones.

 

So fast that Ford stopped using CO to give others a chance to
catch up

 

Terry,

Have you had a chance to take the car back to the dyno?

 

Not yet. Funds I allocated for the dyno were shifted (bought my wife her Christmas present). I had hoped that Airaid would publish the results of their dyno testing of the Boss and the TracKey that Dave said they were testing last month.
