Looks like were besieged by spacer makers. :laugh: Maybe you should join the other guy. Check out the off topic forum. Maybe your from the same camp. At least I didn't have to regestar to see his pictures that he has as an example of. Do you think were all going to register to a forum that we could care less about to view a couplel pictures.

I would like to see how you get a 3/8 spacer between the head and the intake. That will be a neat trick. :laugh:

They need to be 1/2 inch for me. What kind of kerf taper do you get on 1/2 thick if any.  :icon_question: Or do you have a 5 axis head that can eliminate any kerf taper.

How much are you asking for 2 of them?

Yes, this is the same GB mentioned in the offtopic area.  as he pointed out, the thread he copied and pasted was from the Quad 4 add. then people began to ask about doing them for the 3.1/2.8, so i designed some of them as well.  So, no these ones will not go between the head and LIM, id like to see that one done too!  these are of course for inbetween the LIM and UIM.  they also will be 1/2" thickness for the 3.1. 
Ill check on that kerf for you, but i recall it very extremely minimal, but no, there is no 5 axis available at this time. Ill post the exact numbers as soon as i find out again. 

We're looking at about 70 shipped per set.

Need a few more people to make this happen.  If you need additional information please speak up.

Few questions:

1) will this in any way, shape, or form interfere with the upper intercooler pipe, or throttle body, or anything at all? Or does it just go right on, no worries about anything not reaching like it did before? I'm tired right now, just got off work, so all this makes sense to me, but if you need me to clarify, I'll be back this afternoon lol.

2) What kind of gains come with this?

3) Pros as well as cons. Need to know both.

Lastly, how long would you guesstimate this would take for the average person to install? I'm assuming I wouldn't need intake gaskets would I?

The gasket will be 1/2" thick, that being said it will RAISE the plenum that much higher.  I dont THINK it would cause for a big change on how things fit together in the engine bay...  The silicone coupler should be able to take up some of that angle change.

Some of you are probably going to ask, "Well how does this help our engine, what are some of the benefits?" .  From what I know, the phenolic spacer will act like a heat barrier between the UIM/tb and the LIM.  Less heat is always better in our situation (Heat soaking ftl).

The bake lite material spacer goes in between the LIM and UIM.  The spacer would thermally isolate the manifold from engine heat soak, which will reduce the intake air temps.

Now if these engines were N/A 3.1's and not FI, I would not even bother with this Group Buy.  Reason being is that the MPFI runners are so long as it is, it'd hurt the top end (BUT noticeably) even more for the n/a engine.  Which that is the reason the higher the RPM we go the less power we make as it is. So making the runners longer is only going to magnify that problem mainly for a N/A engine like the 3.11 NON turbo.

If you can change plenum gaskets, you can install this spacer.  That is pretty much how easy this is to install.  I THINK you'd need two plenum gaskets (one for the top and one for the bottom) for the spacer since it is a hard material and longer bolts (1/2" longer) to take up the extra length.

I'm in pending pictures of a completed set of 3.1 MPFI spacers.

93luminaz34-  I will probably only be ordering the exact amount of spacers that are pre-ordered.  I understand you want to see a picture first, but I believe by time there are pictures, there will be no more available for sale.  This is why I have posted the technical drawings, so you can see what they will look like, and someone else has posted pics of an actual set they made, other than that, I dont think I can accomodate your finished picture request.  Im very sorry. 

That's understandable. I'm still interested though.

2. TGed-- Paid
3. Styluss -- Payment Pending

I really don't get what kind of performance gains I can get. Until I can get a definate, I can;t justify buying an overly large gasket. Not trying to put it down, I'm sure it's great...but I need facts before I dish out that kind of cash.

You'll know for a fact it'll reduce intake temps since that material will not absorb heat like metal on metal contact would normally do.

I would like to use sleeperred90tgp words for a minute:

QuoteSpacer did 3 things for me. Reduced heat, more room under the UIM for the harnesses  icon_biggrin and allowed my TB to clear the WG. If you run a bigger TB and intake pipe the spacer is a must. I used 1/2'' spacer and with a 2 1/2 intake it just clears the WG.

80 is a good deal. For the DIY the material alone  55 from grainger shipped. It's enough to make 4. About 3 hrs labor if you have a router and a ball bearing bit.  From an N/C machine shop for 20 parts it's around a 35-40 a part ea. depending how they process the program, scan a gasket or go from a drawing that somebody would have to make.
