Mace 6.35mm Manifold Insulator for SIDI?

[vongy10]

just found this on mace's site and they look too big to fit under the hood.
says in the ad that you only get the insulator and gasket sealer also have to use the factory gaskets. wouldnt you need longer bolts aswell?
one more thing; do all 3.6l SIDI engines have a black plastic manifold?

Hey vongy10,

In regards to your questions/statements

"just found this on mace's site and they look too big to fit under the hood."
That photo is of a 25mm manifold insulator to suit these engine in a different vehicle (Camaro)

"says in the ad that you only get the insulator and gasket sealer also have to use the factory gaskets. wouldnt you need longer bolts aswell?"
Not needed

"one more thing; do all 3.6l SIDI engines have a black plastic manifold?"
No. The only way to find out though is to take you engine cover off to see.

If you have any other questions please don't hesitate to ask.

Cheers,
Steve

oh righto. i've got a late 2011 sv6 with the black plastic manifold so would the insulators still suit it?

[Xonar]

that's odd

I thought all 3L sidi had black composite manifold and 3.6L sidi was alloy ?

my late 2010 sv6 is alloy

[bigjim92]

Yeah I thought the 3.6 were a alloy manifold... Mine is anyway (2010)

[VTSS350]

Are you talking about the black plastic engine cover??

The manifold is underneath and is alloy on my VE SV6

That looks bloody horrible!

I assume that's a MY12 model then? Seems holden have been busy changing a couple of things.

WOW...must reduce heat sink being plastic? Are these the ones that have a slightly altered intake arrangement that were supposed to provide some extra power on the 2012 Camaro? If so where is the extra power for the commy and if this is the changed intake manifold have they held off on tuning it to it's potential so they can advertise the 2013 SV6 with more power? If so wonder if it is also backwards compatible? So many questions

The most likely reason for the change is this manifold will be cheaper than the old alloy one.

I saw this a lot when I worked for Mercedes, a number of items changed from an alloy to a plastic, our guess was cost wise.

I can't see it

Going by the above reactions it's plastic.

It's it running exhaust manifolds or are they integrated into the cylinder head? If so then you have an LFX engine so the current manifold insulators we have won't fit (designed to suit LLT)

We should have something to suit over the coming months.

If you do have an LFX engine then we can tune these

Jarp, in regards to the 2012 Camaro I found this,

Ahh yes LFX has single exhaust port arrangement the same as the current 3ltr. So Steve does the intake manifold seating layout differ between the LLT and LFX?

Edit: On second look at the pic looks heaps different...lol...so just ignore my drivel please

[vongy10]

Damn, its an LFX. Was looking forward to getting extractors... Oh well as soon as i can get a VCM OTR i'll definately hit MACE up for a tune. Is there any difference between the LLT and LFX engines when its comes to tuning??

I'm not sure if it'll apply to the V6's, but the VCM OTR doesn't suit the MY12 V8s as Holden has changed the Radiator Mounting brackets, the new design VCM OTR is still a couple of months away from what I've read.

[vongy10]

Mine was built in October so I'm guessing it's an MY11, dealer told me MY12's will come in March.

['11camarols]

yeah the black plastic like manifold is pretty ugly but i guess thats a good reason to keep the engine cover on it lol. the LFX camaros here are rated at 11 hp more with the new LFX over the LLT, doesnt make up for not being able to use extractors though.
at least here the LLT use a bosch ecm and the LFX use a Delphi, so if anything i hear its easier to tune a LFX cause of the new ecm. is this correct for over there MACE?
do any companys offer ported throttle bodys overthere? thats one of my next mods

[MACE]

I suppose the good news with the LFX engine in local vehicles is that it we can run a thicker manifold insulator

[Xonar]

easier to bolt on turbos too
