Interested in these and seeing what they will do in na applications compared to the old ones. http://www.semashow.com/press/2014/11/03/comp-cams-2015-ford-mustang-coyote-cr-series-camshafts

Specs don't seem too different, less duration, more LSA , more lift. I'm not a Cam guru, so I'm sorry if my understanding of the below specs is misguided. I will be interested in what some of the more knowledgeable people think.

2011-2014 Stage 3 NA

Intake Duration @ .050" Lift: 236°
Exhaust Duration @ .050" Lift: 239°
Intake Lift: .492"
Exhaust Lift: .453"
LSA: 126°

2015 + Stage 3 NA

Intake Duration @ .050" Lift: 235°
Exhaust Duration @ .050" Lift: 237°
Intake Lift: .516"
Exhaust Lift: .514"
LSA: 131°

Dont forget, the 2015 has a different firing order than the 2011-2014, so these cams will not work, also, none of the front timing components such as phasers etc are compatible with the 2011-2015.

Says they are available for the 11-14s as well. My only guess is on the 15s it says it works with the stock phasers and on the 11-14 I'm sure you still have to get new ones

We did see that but we have seen no mention yet of a part # for the 11-14's , MMR does however have our own cams with similar specs for someone that wanted them now. We also know that the 2015 cams have still not yet been released, comp claims they are waiting for the cam cores to show up.

So the 15 with a 5.0 is a diff firing order?
I thought the 5.2 was diff not the 5.0.

 

[Modular Racing]

Correct, they went back to the 4.6 firing order on the 15' GT.

Correct, they went back to the 4.6 firing order on the 15' GT.

This information is not accurate.
Firing order for the 2015 5.0 is identical to the 2011-14's. (1-5-4-8-6-3-7-2)
The 5.2 Flat Plane is 1-5-4-8-3-7-2-6

The 4.6/pushrod 5.0/LS firing order is 1-3-7-2-6-5-4-8 (LS you have to convert to ford numbering)

"Cylinder Heads Assembly: The heads are much like the Boss without the CNC porting. They incorporated the CNC porting directly into the casting along with installing the bigger valves like the Boss heads. The cams are a new profile, both, intake and exhaust. Some thought they would be the same as the Boss, but this is not the case with the 2015 engine having a different firing order. The valve springs are the same as the Boss valve springs Even the VCT's are different with the intake cams having a valve system inside that mid locks through the RPM range."



It seems there is some conflicting information out there, the cams are different (as in lobes not in the same position), meaning a different firing order. The dealer however lists the firing order as the same, if this were the case however the cams would interchange (which they do not). We would also assume by Comp cams still not having the 2015 camshafts released that they are a different fire order. We will continue to do some digging in the meantime to add further clarification.

Update: So we have done some further looking at the cams (comparing side by side) and the lobes are in fact in a different location than the 2011-2014. This orientation however may just be the phaser orientation to the cam (which is what our assumption was based on along with some of the other reports that were floating around). We will compare the lobe next and report back with a final confirmation (which may in fact coincide with the member that posted above stating that they are the same firing order), one thing is definite, and that is that they are not interchangeable (regardless of firing order) due to the front bolt pattern being different, our further concern would be the orientation of the fixed exciter ring at the back of each cam.

FWIW I had also heard that the 15 cam profile and firing order changed, there seems to be some FUD from Ford on this. I have heard only the truck 5.0s changed, but have also heard coyote in the stang would as well:shrug: some clarity would be good.

 

[Shaun@AED]

Firing order is identical, I can guarantee this.
Center lines have changed as have a few other variables making it difficult to interchange 11-14 and 2015 cams.

That one article that's out there has people confused.
