I don't see where you're going to get air flow in the valley of the motor. More likely the foam keeps the intake cool rather than hot.TMSBOSS said:Does the foam insulation only keep the engine noise down??
What effect does the insulation have on keeping engine heat out of the intake and therefore the intake air?
Could removing the insulation make the engine noise more pronounced while also heating the intake air???
And? What stops the heat from rising up onto the intake manifold?2012YellowBoss said:I only split the rear piece taking them out, there are four all together (rear, front and two sides). I may have been able to remove it from the rear but did not want to disconnect the hoses there.
This in combo with the Grille and removal of the hood weather strip has reduced my temp 25 degrees on track under load. Also this is with the rear piece still in place, I just removed that and have not tracked yet. I am not saying the foam alone worked but has worked well in addition to the other mods.
I highly doubt the foam keeps anything cool but does trap heat. I have touched the inside of the valley and it gets hot very fast even at idle.
Nothing, the foam is upfront and and behind the open area of the intake and on the outsides of the intake itself. There is no foam between the intake and the engine.908ssp said:
Yes that won't help keeping the heat off the manifold. I saw a picture of the 5.0 foam and thought it filled the whole cavity up to the manifold. That sure isn't what you're describing.2012YellowBoss said:
This is exactly what Scott is saying. The foam in front and in back of the manifold goes all the way from the top of the engine to the bottom of the manifold. Essentially blocking off the open area between the two. The thought is by removing the foam front and back the incoming air into the engine bay will now have free passage into that area expelling hot air with fresh cool air. Now sitting at idle with no airflow will still probably heat things up. Adding some sort of insulation like you are talking about is probably a good idea.908ssp said:Yes that won't help keeping the heat off the manifold.

I plan on insulating the bottom pan on my supercharge when I take it apart in a couple weeks. I am going to cover it with aluminum covered insulation and then gold reflective film.
Lol. Are you sure?Ok , let me have it !! All comments are welcome.
Sorry for the dead link in the quote.It's there for insulation of the intake charge from radiator/under hood heat.
"The foam pads limit the amount of engine heat that gets to the manifold by blocking the front and rear openings at the engine valley."

As for the rear bulb seal...leave it. If you don’t believe me, take it out and test it with yarn tufts in the top and bottom of the hood.
I don’t have hood vents, but did remove the outer 6” - 8” or so off the ends...after a bit of testing.
