New Intake Cam set in development

[Performance nut]

at 1070 wheel on e85 and 1200 on ftw, i haven't seen any drivabilty / tuning issues with the car.

options are always nice, but we've seen 0 issues with the comps on our car or any customers cars

I haven't researched Comp cams for the Coyote engine. Did you happen to have any dyno links for these with similar modifications to this project (GT350 IM, CAI, LT hearders)?

Really quite a bummer that a proper A/B test wasn't performed here...

Got a follow up email:

That is correct. I did not do back to back tests with cams only on the 2016 at the shop, we did that before with the 11-14 cams which these 15+ cams are based on.

Here is a link to the 11-14 testing we did which WAS done back to back with no other changes:

http://www.svt performance .com/forums/showthread.php?1114836-Custom-L-amp-M-Intake-Cam-change-results (remove the spaces)

The 2015+ engines run 13MM lift with the same overall duration as the 11-14’s but with a centerline that is farther advanced. Basically the same lobe as a Boss intake cam but moved 30 degrees on the stick. The thread above was a test of the New custom intake cam VS the stock Boss 13MM intake cam. Gains were as expected, adding 16 degrees of duration netted 17RWHP without a loss of any low/midrange power.

The 2015+ cams are 4 degrees larger and have 1MM more lift than the 11-14 cams tested in the thread above. Same principle, slightly larger as the data gathered in the original test showed we had room for more if desired.

Since power gained is not static for each individual setup we simply have to use math. The engine in the original test gained 3.5% power from the intake cams at 6400+RPM without losing any power under the curve.

One can deduce a slightly larger cam for the 2015+ should net slightly better results, but let’s just say 3.5% power gained from 6400+, on a 420RWHP full bolt on 2015+ car the cams would be worth ~15HP.

Keep in mind these cams work best with higher reving setups like the GT350 and SCJ since the gains only show up from 6400+.

With boost the cams would be worth more power as 3.5% gained is 3.5% gained.

I’ve also gone so far as checking piston to valve clearance on the stock camshaft vs the new intake cam on a factory stock engine to ensure full TiVCT is not a problem. The lobe profile was designed by L&M specifically for use with stock valve springs in a boosted application so valve float is not going to be an issue either.

problem is, most of the time, when people are adding cams, they are making alot of changes at the same time.

hard to get a just before on after, as it's so much work to go into the engine

I'll be happy to pay for the dynos if someone will sponsor the parts and installation

Timing cover gotta come off for intake cam swap?

Thats a lot of money and work for 15hp. Not me, if its not a 30-50whp gain I am not going through all the expense and work. For me this is not a viable option. Those gains could have easily been from the exhaust alone or close to it. I guess someone with deep pockets, low aspirations, and a need to keep as close to stock drivability as possible might be interested. Someone show me what I'm missing. It's easier to tune? I didn't know the better tuners were having such a hard time with getting cams right.

My engine is bone stock right now, and I agree. By the time I install LTs, IM, CAI, Cams, and injectors, my investment is getting into 5K+ territory, and for that money I might as well get a Whipple and leave the rest. When the time comes to upgrade to my next mustang, it will be much easier to swap over as well.

I wouldn't think so.

Yeah, was hoping for more gains from these new cams as well. Looks like I'll be keeping my stock cams.

Like Beefcake said, cams aren't going to be a "go-to" part for most folks due to the cost and time involved to swap them. However, if you're already pulling your motor and going for big power, it's an option.

I certainly miss working on my old 4G63 Evo motor. I could swap cams in that thing in about 2 hours and be back on the road.

I would definitely add the LTs and if doing a Centri blower intake manifold is worth it.

Absolutely. You have to align the crank, remove the chains on both sides, then set the chain alignments again.

There's nothing hard in the process (though it seems difficult on paper), but it is time-consuming.

Maybe worth the time on 11-14 cars but I dont see much value on the 15+ cars.
