Intake plenum and 911 throttle body

[Ben006]

Thanks for the advice

I just received an e-mail saying that IPD's mailbox is full, so they didn't receive my mail... we'll see Monday.


My main goal was to make a plenum that easily drops in place of the old one, without complex intake tube, stretched boots and a almost factory look.
I didn't like the 911 plenum solution, even is it's the cheaper and that it still gives result.

For the intake tube, I don't think I will include it in a kit (unless people really want to, I can figure out a way) as it would just add complexity for me (waiting for more deliveries that might be lost... like what happened with the ball bearing for my shifters).
Two of these:
US 3" to 3 1 8" 76mm 80mm Silicone 90 Degree Elbow Reducer Pipe Hose Red | eBay
+
one of these:
3" 76mm 15deg Aluminum Turbo Intercooler Pipe Piping Tube Tubing L 610mm | eBay
Will make a perfect intake tube! that's what I use:

EDIT: I've just checked, I can have that cheaper if I have at least 10 people.

As you said, the benefit with my plenum is the inside radius, I can't have them smoother!

I first went to the Y shape because the 3D printed part wasn't stiff enough in the version I tested (but still perform perfectly!).

For the 987.1, I think the use the same dimension as the 986 ? And the 987.2 is too big for me :/

Now, I will work on figuring out how to make it out of aluminum (the fittings, small details that will make it easier to produce etc...) and how to make the 3D printed part stiffer without the Y shape.
In case IPD answer negatively.

If you would be interested in getting one, PM me so I can see how many are interested

1) re: IPD. I don't think I would poke that skunk. Their counsel will undoubtedly ask you to cease production and alledge infringement, whether legally correct or not, just to protect their future rights.
2) while I like the idea of aluminum as a more durable material, won't it result in more transfer of heat from the engine compartment to the incoming stream of air, thus decreasing density?
3) I'm interested.

i am interested in one for an 83 mm throttle body - i think i'd pm'd you about this quite a while back - but still need to get you the dimensions; i'll try and do that in the next few weeks.

For peace of mind, I think I will still ask them. The T design is out of their patent, so they can't say anything about that

Aluminum is stronger, but yes, nylon doesn't conduct heat like aluminum does, they both have their pros and cons:
3D Printed Nylon:
-No production run needed
-can easily be made to suit 76 and 83mm TB
-doesn't conduct heat well
-cheaper

Aluminum:
-Strong and durable
-Better surface finish (can be media blasted to achieve the perfect finish)
-A lot more expensive
-conduct heat well

I remember, you have a 911 engine right ? I need the inside diameter and width of the cross tube and the inside diameter of the gt3 TB's exit.

Right now, I have a little something that might be interesting, I'll post another thread
