FRPP intake manifold...is this normal?

I spray a 150 all the time no problems

Ill post up pictures tomorrow, but im taking back my 2nd manifold and going to replace it with a c&l manifold. At 21psi i am blowing the gasket between the plenums out between the 2nd and 3rd runner area on the passenger side. This is the second time this has happened and in the exact same place. First time it did it between my dyno runs (899rwhp/868rwtq) and the 3/4s pass i made at texas mile. Second manifold did it at NMRA with the short tiny hits i made on 6 -8 quarter-mile passes.

Are you saying the gasket is actually coming out of the grooves ? Also how are you "taking it back" ? Is Ford Racing going to give you a full refund ? I was actually thinking about selling mine, but if I can send it back and get a full refund then I'm game. There's a problem with the Paxton kit and FRPP manifold and I can't use my strut tower brace with it so I think I'm just going to go back to stock as bad as I hate to.

This is what happened to me. Two times lol

I'm curious about this as well.

Edit: I see the pics now.

FRPP will certainly warranty that, and that sucks. Sorry for your troubles.

You'd have to discuss returning it to whoever you bought it from. FRPP doesn't sell direct, so it's not up to them. If it's been installed, and there's nothing physically wrong with it, I think you'll just have to try and sell it.

No problems! I really Like it. Made 899/868 with it at 21 psi. Found that's the limit of my stock heads there lol. Not sure if it's been mentioned but fr catalog description for these has changed and mentions nothing about forced induction or boost. I hate to get a C&L (looking for one now btw lol) but I guess I have too.

Thats sweet ! Have you thought about a JPC intake ?

 

[Litebulb]

Yes I'm just not sure how I feel about the inside with the runners so close together.

Wow, so I guess we see the limit of this manifold is 21psi. Did they supply you a new manifold or fix the first one you sent back ?

 

[Greg Hazlett]

+1 for a jpc at those power levels.

 

[Litebulb]

I took first one back to Tommie Vaugh In houston and got another. Second one has been returned and fromthe emails I have seen ford racing is behind the returns !!

 

[Zexford]

Car sounds amazing

 

[Litebulb]

anyone have the jpc cast intake? or the custom intake? its either those 2 or the C&L and id like to have the option to do a direct port kit just for looks lol. Car is being repainted now so im actually gonna try to spend money making it look like it runs! ( hard to do for me )

I have a JPC , what is there custom intake ?

 

[retfr8flyr]

The one you have. They are coming out with a cast version at a lower price but it isn't available yet.

Gotcha. I remember seeing somthing about that awhile back now that you mention it . Thanks.

Do you know the exact scenario in which the FRPP failed Litebulb? Was it at peak boost during a WOT run? Was it at the end of a WOT run when you quickly let your foot out of it? I was going to test one on my car when I got the extra cash to do so but if the manifold does this at only 21psi, I can't imagine it would like 27psi much better!

Looking at how the gasket has been blown outward, it looks like it failed while under boost. I have this intake now, and this concerns even me as well. I'm only running 16 psi currently, but will be turning it up soon.

 

[05yellowgt]

I'm just wondering if it is possible that some sort of boost spike caused the failure, though I'm trying to wrap my head around whether or not too small of a bypass or wastegate could cause the failure since boost pressure would build up on the outside of the throttle body not inside the intake. If I knew I could return for refund in the case of a failure like this I'd be more inclined to give this a try.
