Any Cams yet

[Gudz2015]

Has anybody installed aftermarket cams yet?

I think you would have seen a thread on it if somebody swapped cams. Not a worthy mod all by itself as the 2015 Coyote already has 13mm lift cams both intake and exhaust. Comp and FRPP have cams for the Coyote that have significantly increased duration, some of them require Ti-VCT phaser limiters.

Can you use the cams from the previous generation Coyote?

I would think so, but just in case I would check with one of the shops that have had a 2015 engine torn apart to see if there is any extra clearance necessary. For 11-14 Coyotes, certain exhaust cams required the heads be milled slightly for clearance.

Don't quote me on this but I think they changed the firing order for 2015. it went from the old flat head firing order back to the 351 or 302 order

very absolute last thing I would spend money on heads / cams

I heard this as well on a cj pony parts exhaust video.

I would go with heads/cams and power adder. Just haven't decided on power adder yet... I see comp cams has some.

we put the comp stage 3 in our 2011 car, it picked up maybe 1mph at the track, maybe ......

very disappointing

The cams on a 2015 are different from 11-14 due to the change in firing order and intake cam phaser.

Cams will pick up power on an N/A car and even more on a S/C car. We have achieved over 600hp on a 2013 naturally aspirated Coyote racing engine and plan to do the same on a 2015. When doing a cam swap on 2013-2014 Cobra Jets we are able to pick up nearly 100whp with no other changes.

The safest way to pick up big power with cams is to delete the beloved TIVCT system so you will trade low end power for top end power. On a supercharged car such as a Roush or Whipple, losing the low end power isn't as big of a deal since the PD blowers produce instant torque. An N/A car would have to be set-up properly to keep the motor in its usable power band (gears/stall speed).

The problem here is that most boosted setups can max out the fuel system and stock internals without touching the heads/cams. So as Beef said, it's one of the last things you look at when boosted. If you want to do a baddass N/A build then we are the ones who can help.

This car has our custom cams locked out and degreed in.

It seems for 2015 the limiting factor is the intake manifold. He doesn't really want to support anything past 6500. I can't help but wonder what a Cobra Jet intake, throttle body and intake tube set up, with the stock heads and cams and tuned to take advantage of the upper flow would do. Keep in mind for 2015 we basically have boss heads with Cobra Jet cams

I would think a good tuner would be able to preserve low end torque while allowing the cans to take their full effect up top with a Cobra Jet intake manifold.

The 2015 cams are the same lift as the CJ cams(13mm) but no word on duration that I've seen. Duration, especially on the exhaust side, has been proven to be a bigger benefit on a NA Coyote. There are 'Mini-CJ' cams with the same 11mm lift as stock for the '11-14 Coyotes but bump duration up from 263(IIRC) to 290 degrees and they were worth something like 20+rwhp on an otherwise well-built but stock cammed Coyote(CJ intake, 7,800rpm redline, billet OPG, headers).

Does anyone know the stock cams Duration, Valve lift and Lobe separation angle?

There is no lsa. That is set in the computer and variable since one is intake and other cam is exhaust.

All camshafts have a Lobe Separation Angle. It's inherent in the design. The stock came are just really really wide, like 126-139 wide and then are variable like 50 degrees.
