Hey guys, I took advantage of the Black Friday sale and purchased these:

Full Race | Full-Race 2021+ Ford F-150 & Raptor 3.5L EcoBoost Formline® Turbo Manifolds (GEN3)

If you are not familiar here are the claimed gains with just this part alone being swapped:



If you're attention span is such that the 7 minute video is too exhausting to watch, well it's not a perfect test. They compared a dead stock truck, to a different truck that had the manifolds and a tune, and they put that second truck back to stock to isolate just the manifolds.

The stock truck with stock manifolds to a different stock truck with manifolds showed a 52hp/ 45lb (10%hp/ 15% tq gains) higher numbers with the manifold truck. The issue for me is that even different sized tires can alter a baseline setting. It would have been better to install the manifolds on the same truck.
They then tested a tuned truck with stock manifolds vs. a tuned truck with manifolds and showed a 55hp/ 78lb (13%/ 15%) gain.

Looking at the dyno charts shows substantial 'under the curve' improvements which is what really matters.

For me, I figured that this was likely the next low hanging fruit and honestly my final engine mod. I've looked at the turbo kits and those guys are spending $8K for like 50 rwhp, from what I have seen. No thanks!

So, me and a buddy installed the kit, it sucked honestly and took us 12 hours total, and he's a professional tech.

Now at first, I noticed some small changes. But mods are like that. You expect some huge change and at first you are a bit disappointed, but after driving your usual routes for a few days you start to notice some real differences. Also, it's important to note, that when the batteries are disconnected for hours, there is a relearn process and the engine will be more conservative with boost and timing as it slowly creeps in the timing testing the limits. Livernois informed me of this. This still applies with the E85 tune I run. It's also a reason that if you swapped these and redynoed the same day you would not see the entire gains.

So for the differences: They are pretty substantial honestly. I know there are faster (and lighter!) trucks than mine, but she really scoots. It absolutely gets boost easier. Some of you might have noticed that you need substantial throttle to see any boost pressure, like over 1/3 throttle I'd guess. Well, it picks up boost easier for sure. The match between the new manifold and the turbo is much better now and I think velocity is improved in spite of the larger diameter and the turbo just spins up quicker. Peak power is absolutely improved a noticeable amount. I'd believe 50 rwhp, easily. Since my set up was likely somewhere around 550 rwhp per Livernois, it stands to reason that my gains might be a bit higher and I'm probably sitting a bit above 600 hp/ 600 tq at the rear wheels.

There is a small sound change but it's minor. The motor has a tiny bit of grumble that it did not have before.

So that's my last engine mod...I swear.

Any idea how much these manifolds improve your 0-60 or 1/4 mile times? I have a set waiting to go into my truck, but I'm in the middle of moving and remodeling half of our new house, so it'll be awhile before I can do any testing.

Definitely a good step after your intercooler. Is there a coating on them to keep the heat in?

Good questions guys.

Sorry but I don't have before and after times. I really don't ever go over 85 mph. My usual thing is to get a nice pull from 5-70 mph merging or whatever. What I can say unequivalcably, is that's it's faster. It feels 'fatter' during the roll ons but it actually feels a lot faster on a full throttle pull. Where-as it used to feel very flat past about 4500 rpm it feels considerably stronger up there now.

They have a ceramic coated option which I bought. Maybe the manifolds will just look good longer but you can't see them anyways. Maybe it reduces underhood heat? Maybe it'll actually retain heat and improve spool up. I don't know, but I didn't want to second guess myself.

Regarding my intercooler mod, I often wonder if it does anything at all considering that I run E85, even when towing, and my combustion temps are so low anyways. Just not sure it matters with E85.

The correct order of mods is (imo): Good oil and good sparkplugs (really, new spark plugs made a notable difference in how my truck runs), an AFE Momentum intake as I could clearly feel it for not much money, then probably an E85 tune & lastly these manifolds.

The bang for the buck really drops after this, and I don't need any more power anyways.

I'm not surprised that at first impression, just adding the FAR SUPERIOR manifolds, but not altering the "tune" of the truck, it might seem underwhelming as an improvement.

The 3.5 Ecoboost is a torque management engine. Adding the manifolds wouldn't change the torque request that you make with your right foot. If the PCM sees a request for 250ftlbs of torque, it will still only call for the necessary fuel, boost, timing, and air to create the 250ftlbs of torque.

I'm sure I am oversimplifying, but not by much. I do think that you might sense the request being fulfilled more effortlessly? More refined? But the real potential that those sweet manifolds offer would be mined from them with a tune.

Still, I'm admittedly envious!
I'd love to wake up tomorrow morning and discover my oem calibrated Powerboost was magically equipped with those exhaust manifolds. 😁

I'd say after driving on them for a few days, that there is a distinct difference in the way the truck picks up speed. It's really quite noticeable and the truck feels hella fast, yet still totally refined , smooth & quiet.

As far as tune changes, the manifold people tell me that with the manifolds you get less knock and the tuning can be made more aggressive. Livernois told me the manifolds would barely make any additional power and it's well within the natural adjustment of the truck.

Anyways, I plan to enjoy the power as it is for a year or so, then I'll likely run a scan log and request more power. I'm in no hurry. It's more fun to get a little more at a time anyways.

In Normal or Sport mode? Livernois 93 octane in sport mode will pin you to your seat.

If it's true that those manifolds would reduce knock, then it's very fair to assume that lower KR will result in the PCM switching to a more aggressive timing table.
That's the beauty of the Ecoboost torque management. And a few additional degrees of timing can absolutely increase performance, even with the factory calibration.

So that's a good point!

I honestly only run it in normal.
Sport mode made a large difference is responsiveness when the truck was closer to stock. But ever since I swapped to E85 normal mode is very fast and sporty now.

I don't think the power is different, it's just that Sport holds 2 gears lower so it's more responsive.

Yeah but how was the install? This sounds great and all but I have another V6 TT in the shed and this is an engine-out job on that car.

I see that you said 12 hours, but anything of note? What was the process like?

You must become one with every oil feed line and coolant line retaining bolt, Grasshopper.

You must 'woo' the turbo both out, and in on a PB on the passenger side. Make love to it!

I usually headline my projects but in this case I followed my buddies lead and although I definitely did my part, he'd often just say: 'remove this (pointing behind the block) and this (pointing to a hidden bolt behind the turbo)' and he'd move to the other side.

Look, it's not fast, but with the right tools and 1.5 days of patience, you can do it. There are online instructions. A PB adds another dynamic. I usually knock out the hard side first, but in this case I'd suggest doing the easy side first (the driver's side) because you can see the fittings much better and you'll have a better idea what to do when you can't see them on the passenger side.
