Intake manifold material

Can anyone with a spare intake see if they can find the material stamping?

I need to know the material and the stamping does not appear to be on the top side.

 

Top air chamber is plastic, intake manifold is aluminum

 

I think they're more interested if it's stamped something like "ABS GF15" or along those lines.

 

Exactly correct, although thanks to @Vlady for the quick response.

 

You might try tagging the guy with the ACIS Thread, l believe he cut a manifold open.

 

I have 2012 one with PA6 GF30
and 2022 with PA6 GF30
Most likely is the same for tacoma

 

Awesome, thanks!

And crap, that stuff is crazy expensive as 3d printer filament....

 

Printing the spacer?

 

Considering it.

Lots of stuff to drop $300 bucks on before I go for that....but if it was $50 and I do it myself.....

Unfortunately it looks like half a roll of that material is in the $50-75 range, five times more than normal materials

 

Lol did you expect it to be cheap?
Reliability and durability cost money. I would not expect any material spec on a Toyota to be cheap.

 

I have never printed those items so I'm going to have to say no. I focused almost exclusively on functional items and don't have the expertise in making good figurines.

You need to find someone with a resin printer, those things are great for figurines.

There are a few for-hire companies out there, and a few communities as well. Shapeways is one such company.

 

In reality I wanted to know the material so I can get the material properties, specifically the temp ranges they designed for. The spacer itself undergoes different stresses than the manifold and doesn't need the exact same material. Simply put it is only in compression, the manifold itself experiences a ton of different stress.

In this case it looks like this material has a high temperature operating range (which is obvious) and is about the only material to have that range (that I have found). Thus the best material to use is the same material which is unfortunate, I had hoped other materials could be suitable

 

Not sure I'd go the 3D printed route, as it would likely cause vacuum leaks, especially if it's an FDM type printer.

You can accomplish the same by tuning ACIS. And because ACIS can be activated and deactivated, you don't need to worry about losing any HP/torque.

 

Lots of guys printing manifolds and manifold adapters, it works quite well.

Acis cannot make the runners longer than they already are. At low rpm it's already giving the maximum length. The spacer physically makes the long runners even longer

 

I'm sure it can work, but there's a pretty good chance it'll throw a code (or two) with our trucks.


Also, a bit of reading material for you:

 

I don't know what to tell you, folks are using fdm for intake manifolds now. Lots of guys having great success doing fuel injection on a variety of engines with printed manifolds.

Yes, I understand how the acis works. At low rpm however it is already at maximum runner length. This new spacer can make those runners even longer, moving the power band down in the rpm range even further. A spacer works with the acis valve

 

I don’t know if it’s possible on a third gen but I’ve made 2nd gen spacers by cutting the base off a spare one. Been running mine on my truck for 4 years with zero problems. The few others I’ve made, I haven’t heard of any problems from the folks that runs them either.

 

Again, I'm sure it can work, and I'm also sure you can use a spacer with ACIS. Not saying otherwise. Regardless, there's at least 16 different DTC's I found that can be output from a vacuum leak caused by a warped print, or other print issue. FDM just doesn't produce at a quality I would trust to work, especially with the complications of printing a material such as nylon 6 and knowing how touchy these trucks are. If it were for a first gen, it wouldn't be a big deal, but this current generation will sometimes throw a truck into limp mode if aftermarket tail lights are installed.
