Just installed the Bullitt CAI and SCT Tune - what a difference, should have done this a long time ago !

Install was easy, the only issue was the front hold down mount to the ABS module. Stock is a 8mm bolt - had to swap it out to a 6mm, to fit the new airbox grommet. Also I used the stock air tube with no problems.

A big thanks to KC @ Clevenger parts. He answered all my questions and gave good advice. We live in the same town, so he dropped it off at my house - great service and price.

Thanks to Doug @ Bamachips also. Easy order process and delivered on-time. The tunes sure do wake things up !

More Mods to follow - thinking about 4.10s.

 

Out of curiosity, why use the stock air tube instead of the Bullitt air tube? Also, if I order the Bullitt CAI, does it come with the Ford tune and can I do it myself?

 

Which tunes did you get? It seems that Bamachips is the way to go to get the Bullitt CAI tuned. I don't recall seeing anyone with a Bullitt CAI and having a Brenspeed tune, any reason why?

How much did the whole set up cost?

 

The Bullitt air tube is approx. $90, so to save some cash I wanted to see how the stock tube would fit. I think it is OK.

I ordered just the Air box and filter from KC @ Clevenger parts, I have heard that you can buy a package that does come with the Ford tuner.

Installation was easy, if needed I can detail the small parts used for the front mount.

 

I got the 87 performance, 91 performance and 91 torque. Both 91 tunes are great, have not tried the 87 yet.

After reading Doug's (Bamachips) post on this, I thought he was the way to go. http://forums.bradbarnett.net/showthread.php?t=461832

You can get the "Hotsheets" from KC, he lists all his prices there. http://forums.bradbarnett.net/showthread.php?t=421531

Also I have had a Deluge of Bullitt Intake Requests. I will do my Best to Get caught up on Some Backed up Emails tommorrow.

Does it look like the FRPP FR1 kit comes with a Bullitt CAI??

 

Thanks KC. Don't worry, after all of the great things that are said about you on this forum you're the first person I'm calling for any Ford part that I need. When I get the money I'll probably get in touch with you. I'm really leaning towards the Bullitt CAI. I guess I'll just have to buy the tuner separate.

 

I've alway said that the best thing I did for my mustang was the MAC CAI, Brenspeed tune and the dual Magnaflow setup, runs well and wakes up the neighbours.

 

Is it required that after adding the FRPP or Bullitt CAI's, that you must have a tune that requires a higher octane fuel? I'd be interested in one of these systems, but I'd really prefer to be able to keep running regular 87 fuel. Also, if there is the ability to run 87, does it pretty much negate the whole gain you'd get by adding one of these CAI's?

 

The MAF housing on the FRPP/Steeda CAI is larger than the stock airbox MAF housing. I'm assuming this is also the case for the Bullitt. Therefore a tune is necessary in order to recalibrate for the increased amount of air the engine will see as a result of the larger MAF.

The good news is you can get your tuner to provide you with 87 octane tunes along with the 91/93/94. You'll notice improved throttle response and more of a kick, even with an 87 tune.

The alternative is to go with a CAI that doesn't require a tune, but the HP increase will be minimal.

 

Got it. Thanks! That helps to know that.

 

The Bullitt CAI and any non-stock air intake will have a different air transfer function. If you know the air transfer function, you can just slip that into the programming for your PCM. This is what I did to retrofit the Marauder MAF and airbox in my 2000 Crown Vic. You do NOT need to use 91+ octane with an aftermarket air intake. The only benefit to having a 91+ octane TUNE is so the ignition timing is bumped up a few degrees resulting in slightly more power with a stock motor.

The CAI's that "don't require" a tune still require a tune regardless of what the vendor tells you.

I ran my Pypes Violators for about 6 months and it was too loud for me.

 

The MAF housing on the Steeda/FRPP CAI, is 90mm. Whereas the stock airbox housing, is 80mm.

That being said, your assumption is correct. In which a tune is required whenever the MAF housing becomes larger than stock. As does the Bullitt CAI, which also requires a tune. Due to it's larger 85mm MAF housing !

 

No, it's not just the MAF housing that causes the change, it's everything upstream of the MAF including the housing and sensor wire. Each MAF sensor is calibrated for a specific airbox/intake setup.

Even the K&N CAI that re-uses your stock MAF sensor and housing size requires a tune to correct the air transfer function.

 

So why does the air transfer function need corrected, if both the stock MAF sensor, and housing size remain unchanged ?

The only difference I've noticed with the K&N CAI, is the intake tube has a slightly larger elbow downstream from the MAF sensor/housing.

From my understanding, as long as the MAF sensor and housing size remain the same. The air transfer function shouldn't require correcting.

 

It needs to be changed because you are not using the stock airbox and filter element. Like I said in the past, the MAF and airbox assembly/filter is calibrated as an assembly. If you change one thing in that combination (like the airbox/filter), you will need to get a retune to fix the air transfer function.

 

Thanks for clearing that up Charlie, as this really puts everything in perspective and does indeed make very logical sense.
