FRPP intake manifold...is this normal?

[US-1]

I'm just amazed that none of you have hit upon the real concern I have about these things moving AT ALL....any amount of movement. With the fuel rail moving even a 1/4" the injector o-rings are being moved in a side-to-side fashion. Injector angle and fuel rail alignment are critical in order to prevent a fuel leak where the rail "cups" over the top of the injector on the pressure side. Y'all are worried about this thing cracking when you should be worried about a fuel leak and a FIRE! Who wants to be first on that list, kids?????

On top of it all....I keep hearing "bad casting." How can you have a bad casting when these suckers are all injection molded? Every single intake will have this problem. There are also reports of the throttle body flange being too thin and moving around causing a leak.

well we will put this sucker to the test in a few weeks. We are testing it on our shop car and it's gonna be seeing countless blasts down the strip for the first couple months.

Better have a good fire suppression system on that car. Nothing like being on fire, in the lights, at 120 mph.

Yup. That is precisely what I'm afraid of. I don't think this thing will crack at all, at least not before several thousand cycles, which honestly wouldn't take that long in a daily driver application. But how many times of the fuel rails rocking the injectors back and forth in the bosses before that o ring grinds itself away?

I spoke with ray at frpp just now. He said they already heard from the op and they are looking into it. Said they would call me back as well. Mine doesn't move as much as his but it does move and my stocker didn't. I'm with you US and was waiting for you to chime in. It should not move bulge or collapse in. Nothing but function like the stock one as they prompted it to perform as well or better than oem. How does a moving intake perform as well? So I will also be on the horn with them for a solution. I just spent over 4 grand with them. Damn it I should have went boosted and not n/a........

 

[lostsoul]

great.. I haven't installed mine yet.. maybe in a month when tuner gets here.. I hope we are not having a massive recall. So there should be zero flex.. We need others to chime in..

 

[06GTMustang89]

I just sent mine back for a return and I'm going to put the stock one back on in the meantime until we hear something from ford my guy at frpp was stunned they know they have a huge problem now

 

[Booya]

I just looked at mine, sure enough, black lung disease too.

 

[06GTMustang89]

They are going to recall all of them I'm sure now so I'm getting my money back and getting the c&l manifold aluminum won't bulge like that

there can't be that many of them out there. it's not like everybody with a mustang gt has bought one of these.

 

[Booya]

They are going to recall all of them I'm sure

Of course after I sell my delete plates.

 

[TheKurgan]

Cancel my order AJ. Damnit!

I don't know man, I see on every site how bad people want this, seems like one of the fastest growing trend mods and "Must Have" for centri guys.. Not to mention pulling all the ones off the suppliers shelf.

Either way I hope they fix it and fix it fast.

 

[Starfire]

Just bazaar! Intake manifolds aren't supposed to move, though in some strange way it's kinda of cool.

 

[Mustang30212]

Just talked to my FRPP dealer and he hasn't heard anything about it...yet.

He did mention there was some sort of issue earlier after the intial release that had to be fixed....thus causing the recent back order. He couldn't remember what the issue was...but he's calling Ford Racing now and said he'd let me know.

In for details. My manifold is supposed to arrive today and was gonna install and time wed. Guess I need to check for this after install or maybe check for a cause

 

[dalemllns]

Of course after I sell my delete plates.

Exactly... I sold mine to 2to3three on here and hes got them now. DAMN!!!! They had better replace mine with a new one that doesn't flex. This is bullsh*t....... Im not taking mine off till I have a replacement here otherwise the car will be down untill the replacement arrives........ughhhh

That was the throttle body flange flexing.
