Noob Engine Cover Question

[bpd1151]

Back in early 2011, there were failures of the HPFP due to that foam block being in place.

It actually RETAINS HEAT, not the converse as discussed here.

One of those failures occurred on Kirk Doucette's SHO.

Most of you know Kirk's involvement in the SHO world, spanning many decades.

Kirk also has direct insight with the entire engineering development team that built the Gen4+ SHO platform.

Kirk learned the only reason that foam block was put in place, was simply for noise suppression. That's it.

I removed the foam block on my SHO that same year (2011) & threw it in the garbage. Never have had it on since, and nor have I had any problems either.

Thank you very much!  That is the exact impression that I get from looking at it.  It is on top of a unit that has a heat source underneath it.  That would not lead to heat removal, but instead heat retention.

[bpd1151]

That is correct and you are welcome.

I guess fords logic is that keeping it on there will lead to more failures due to heat and create job security for the service techs in the form warrenty work....my mistake lol

Its not unheard of for fuel to boil inside those pumps. At the same time heating the fuel in the winter can be advantageous for fuel volume so maybe the answer is running in winter only. At least for the corn guys.

mmm, corn

When changing the spark plugs on my MKS this weekend...i noticed there was also "foam" of some sort under the upper intake manifold/plenum.  Do SHO's have that?

Never seen anything like that before...

My original engine cover does... But a Ford factory replacement purchased for a CF wrap does not... Pros and cons related to noise and heat I suppose.

Ryan due post some pic's of the location,question in mind,thanks.  Z

There's a foam cover for the HPFP, for sure, as it is a noisy little bugger   But like Z said, post a pic of the exact piece you are referring to.  Some pics of the general area are in the recent 3bar location thread:

Stole the pic from above, so apparently all the 3.5's have it.  I circled what I'm talking about in red.

It should have the "Foam block"according to page two on this thread,think the other member has a 13 MKS and was also inquiring about the removal of that piece in question.  Z

Just seems weird to me that Ford would squeeze a big piece of foam under the intake plenum....

It's up for debate, but my initial impression has not changed.  I believe all of the foam is to help quiet the natural noises caused by direct injection.  I also believe that these sound deadening materials come at the cost of additional heat soak.  You can't insulate from heat by adding materials on top. 

Unless those materials are actively or passively cooled.  These dense foam rubbers are neither.

Someone with datalogging abilities could probably do some tests to see if any of the changes are significant with/without the sound deadening materials in place

It looks like the 15+have it also.  Z
