10HP Loss, Not compression! Real reason exposed with Dyno Proof

[Dfeeds]

Thats why the Ford Performance Power kit won't work, it removes that hydrocarbon trap.

Except the power kit uses the same intake as the bullitt, gt350, and now mach 1. The mach 1 has this hydrocarbon filter added. There's technically no reason why they couldn't update the kit to use this new carbon filter contraption and sell it for the '22. I say technically because cost analysis could've ended with a fat "not worth it" for the last two MY of the s550.

I think the old design has the carbon trap, too. Unless I was seeing things, I could've sworn I saw one flush with the tube, right after the air filter. Except that doesn't obstruct airflow, which is a big no no for the EPA.

I pulled my stock GT air box off this afternoon and found the offending carbon filter and the plastic shroud that holds it in. It is missing now And I took it for about a 30 mile drive with no ill effects that I can tell. Didn't really get on it too much so can't tell any difference in power, course mine has felt really healthy since day 1.

who do you think stole your filter?

I felt it a bit more in the low to mid range. I don’t “feel” power but acceleration feels better if that makes sense.

Time to break out the TOOLS

it requires a 10mm dude. I know I have to go to the store tomorrow now to do this. :/

FWIW, this is what I used (to remove a Mach 1 assembly):

10mm: CAI assembly.
8mm: air filter.
7mm: throttle body.

Flathead for the air filter and throttle body work. I like the better engagement of the socket.

Torx: to remove the airflow sensor in the intake tube. Sorry, my Torx isn't marked for size.

Flatheads/picks x3: to set the tabs (in the Mach 1 tube) so the EPA filter can be removed.

I have an emergency 10mm that I keep in my bag xD no need to hunt one down thankfully.

So if we take this 20hp pickup at face value, we can assume the mustang is legally underrated by at least 10hp?

Back in the late nineties when the 4.6 4v cobra engines jumped from 305 hp to 320, ford had to update several cars because they did not get the advertised 320 hp. Ford got burnt big time because of that, ever since ford underrates everything. Who's going to sue because they got more than they paid for?

HAHA. My trash can stole it, I would put money on it

You have to remember that a dyno is a tool to measure a difference in power before and after mods, study the power curve, and to dyno tune. Of course it can give you a estimate how much the car is making. But there is a margin or error there due to so many factors.

Its possible the car is slightly underrated though.

welp i'll be taking a look as soon as mine shows up

so if this is true a cold air intake will result in actual hp gains without a tune in the 2022's cause it'll get rid of all the factory restrictions.

Sure, but why go to the expense? The OEM CAI is great, just remove that stupid extra filter.

I just got back from the garage and wanted to see the carbon filter everyone was talking about. Yup turns out my is missing also. Maybe the factory forget to put one it.

 

[KingKona]

car does have much better throttle response after removing this crap

jd, what car did all that stuff come off of? Obviously not the 2019 GT in your signature.

JD, please clarify.

Accelerating feels more “crisp” and responsive from low to mid range rpm’s.

I wasn’t aware of this but it is *exactly* what I’ve been saying all along. Ford isn’t likely to promote an actual 20 hp drop as only 10 hp because they know it’s inevitable that it’s gonna cost them $ to bring the affected cars up to spec. I‘m sure they’ll err on the side of caution.

Now this might be their get out of jail free card: what is the commercially acceptable [read lawsuit proof] margin of variability in ratings within an engine family? These engines can be the same but they aren’t identical. Obviously if the allowable valance is say 2%, then any two random engines could be 4% apart. Luck of the draw would seem to be part of the deal.

That small carbon trapping filter in the GT. Do you guys really think there is 10-20HP gain? Kind of hard to believe my car now has a 20HP gain.
