Comp Cams - 2011-2012 Mustang 5.0L Coyote Camshafts - AmericanMuscle.com

[AMChrisRose]

It's that time! We've gotten literally hundreds of inquiries about the 2011 & 2012 5.0L Coyote Mustang cams. The wait is finally over! They're in-stock and shipping. Can't wait to bolt these up to our 2011 Automatic to see what it'll do to our current 10.43 @ 130mph. We'll have dyno results and more soon!

Want some specs on them in the mean time?

None of these are spring required cams, however ALL OF THEM need the phaser limiter kit, which we'll have up on the site soon.

Stage 1 & Stage 2 Cams are compatible with stock gears and stock converter, while the Stage 3 cams need a 3.73 or steeper rear gear ratio and long tubes. Converter will probably be a good idea in Stage 3 as well, but we'll know for sure once we install them in ours!

Awesome news...How come BBR is saying they are not ready yet?

 

[AMChrisRose]

Not quite sure. They're definitely in-stock and ready to roll!

 

[wazslow]

Not quite sure. They're definitely in-stock and ready to roll!

But what good is that with out the Phaser limiter kit? LOL

 

[AMChrisRose]

I know, LOL. We had an issue with the PO we sent in. They'll be in-stock, ready to ship and on the site in less than 2 weeks, max! Sorry!

Do you need phase limiters on both cams?

 

[AMChrisRose]

Stage 1, 2 and 3 all need the phaser limiters. They're about $70-75 bucks for the set, I believe. They just limit VCT to 20 degrees for piston-to-valve clearance.

 

[Rob72]

What I meant to ask was are they needed for the both the exhaust and intake cams or just the intake?

 

[RedMustang]

Awesome

 

[JDM74]

I see it says LSA of 126 degrees. How do you specify a LSA for a VVT 4 cam engine?

this.

May be the max/widest value achievable with the independent timing since the intake and exhuast lobes are on seperate camshafts.

 

[JeremyH]

The limiters would be needed for both cams since you have intake valve to piston clearance as well as exhuast valve to piston clearance to worry about when increasing lift and changing lsa.

What are the stock cams rpm operating rang?

 

[JDM74]

The limiters would be needed for both cams since you have intake valve to piston clearance as well as exhuast valve to piston clearance to worry about when increasing lift and changing lsa.

I tend to agree here, but why wouldn't they give a range for LSA achievable with these cams and the required phaser limiters.

 

[JeremyH]

I tend to agree here, but why wouldn't they give a range for LSA achievable with these cams and the required phaser limiters.

Not sure, I guess the max hard range and what it can actually acheive in the tune are different. Just like the 3v, the phaser could theoreticaly/mechanical allow for 60 crank degrees out of phase but the tuning never exceeds 20 degrees.


Also these tivct buggers are pretty new still.

Sorry I'm not all that knowledgeable about cams... but why do you NEED longtube headers for the stage 3s?

 

[JeremyH]

Peas and carrots. The cams increase lift and duration so they are moving alot more air so just as it pulls it in, it needs to let it out.

 

[08StangGT_CS]

Any testing on these yet?

 

[AndrewG27]

I still don't see the phase limiters on their site. Any updates on when they will be available?
