EG33 Prototype spacer

[alltrac]

Sean at Outlawengineering.com sent me this picture. He also requested the injector base to intake manifold collector gasket reference 14075. I think this is a good idea as the heat from the cylinder head will have to go through two spacers. I have not received them yet as I mailed off the collector gasket yesterday.

So basically, this just insulates the intake from the heads, right? What I don't get is there are a zillion hoses right underneath the intake, and.... I don't know if you've ever just popped the hood of your SVX after drivign around, but the whole ENGINE bay gets warm. I really don't see how this is going to make much of a difference, but...eh... prove me wrong!

It looks like you are putting same theorem that goes into cooling overclocked computers and putting it into automotive application.

The difference is even though the heat sink on the RAM does dispel heat from RAM chips themselves, through relatively simple terms of conductivity. The difference is after the heat is dispelled it is quickly ported out of the computer through, either the back, side and/or even Southbridge fans. Where is the extra heat dispelled from the heads is going to go?

It would be cool if someone did this and then put hood, and perhaps even Buick GNX or Ferrari styled, side vents either adjacent or somewhat behind where the heads are.

And if you want to take is a step further you can clip on little fans on the insulating rim things to port out the heat even fast, like cooling a processor.

I'm still new when it comes to automotives so can someone give me some pointers if this works or not. And even if I grasped the concept posted or completely missed it?

The entire intake has an excellent source of cool air. The intake! All it does is suck in outside air, and usually under a vacuum, which only makes it colder. What we have is an aluminum head with an aluminum manifold. Aluminum, being the excellent conductor that it is, naturally conducts a lot of heat from the heads and transfers it to the intake manifold. The heads tend to be kinda warm, because there's a freakin' fiery explosion going on in there. The intake just sucks cool air.

The engine compartment does get kinda warm, but when you let it stew for a few minutes before opening the hood, everything is much, much warmer than when you're driving.

The intake currently has gaskets between it and the heads. These probably reduce heat transfer considerably, all by themselves. Even thin paper gaskets would make a huge difference. I don't know that further insulation would really have a great effect. The point of diminishing returns may already have been reached. Additionally, as with any aftermarket component, I always have to ask why the manufacturer didn't already think of it. Despite my skepticism, this is actually a pretty good idea, but I really don't know how poorly the current gaskets insulate the parts. I'd like to have data that demonstrates a significant deficiency in the current design.

I think the best idea of this nature, is the plastic intake manifolds that some newer cars have. I think this is a great idea. I think I saw it on a VW once, though I may be wrong. That kinda scares me because German plastic tends to be pretty lousy, but the idea itself is genius.

Personally knowing that I can't put my hand on the intake after driveing for a while tells me(as well) that there is some major heat transfer so all I want to further this is WHEN DO WE GET TO SEE THE DYNO RESULTS?

the new Legacy has this, too.

Victor these are the prototype phenolic spacers for the intake manifold and throttle body. Did they give you an estimate on the price yet?

This was the response I initially received from Sean. It should answer Q's about cost if you want dyno results someone should have stepped up and gone down there. I was left with no choice but to send OEM gaskets so they could mock them.

Tom/Victor,
We have been developing ThermoBlok insulators for many new applications, but the SVX is not currently on the list. Our prototyping work order is organized by demand and to date, there hasn't been any other interest in insulators for the EG33 motor, yet. We generally request 20 commitments prior to the design, prototyping, and production of a new performance part. Pricing for a set, including intake manifold and throttle body insulators along with necessary hardware such as lengthened studs would be in the $100 or less range.
To prototype a new set, we generally prefer to have acces to a full vehicle. This will allow us to investigate fit-up issues and to do a before and after dyno test to asses performance increase. We are located in Indianapolis, so if there are any interested parties in the central Indiana area that would be interested in having their vehicle used as a test bed, please step up. This would include a short session to evaluate the vehicle and take measurement data, followed by another session a short time later to install and evaluate the prototype set. This, of course, would be done free of charge.
Please asses the interest for your group and let us know.

Best regards,
Sean Morgan

Chike you can compare these gaskets to Outlaws photo

[SVXRide]

Looks like Outlaw's pieces are 3-4x thicker than the stock gaskets. Prices yet?

Those look pretty nice. Looking forward to hearing the price.

I think I remember seeing this on chrysler products in the mid 90s... it's not plasticy plastic, it's kinda ...plastic with fiberglass in it, or something. It's pretty tough stuff.

Saying something is plastic is kind of like saying something is metal. Many types and many different characteristics (think tin or lead versus stainless steel or titanium).

The intake manifolds are injection molded from glass fiber reinforced polyamide, aka glass-filled nylon. Lighter weight, less cost, and more quickly produced than cast aluminum.

Thanks for the clarification, you totally out-geeked me.

[UberRoo]

Reinforced polyamide, you say? Now I know. It's neat stuff. I hope to see it used more in the future.

Frankly, I wish cheap plastics would just go away. There are so many great "plastic alloys" available. The low quality junk really contaminates the otherwise good selection of quality synthetics. The stuff Glocks are made from is fantastic. Kydex is similar and also amazing. And how about the stuff bumpers are made out of? Makes me want to strangle someone every time a Bic pen breaks in my pocket, or the plastic hinge on an SVX sun visor cracks and won't stay up despite virtually zero use. ...and I despise European plastics with a passion, namely Volkswagen's. Ugh! I hate that stuff. I swear it's made from chalk. No really. You can even write with it, and it gets a soft film when it's exposed to water for any length of time.

Seeing as my engine is in bits I thought I might bolt on a set of Thermobloks by Outlaw Engineering as it's being put back together.

Nearly 10 years has passed since this thread was last posted to.

Has anyone actually installed the Thermoblok ?
Did it work ?
Any problems ?

cheers, Shane
