Intake plenum and 911 throttle body

No problem Alfieg


Alright...

Who want one?

But...
I need guinea pigs!

The one on my car is fine, it works, it has been there for more than four months now and I'm very satisfied.

But now, I need a few people that are interested in getting one and that are OK to be guinea pigs: Give me their feedback, collect some datas if possible, etc

Preferably if you have a S model, as I'm sure the 3.2L engine will react even better to the mod.
And even better if you already have an aftermarket exhaust system!
The testers would pay at cost, it's the best I can do.

Keep in mind that with the plenum, you'll need to buy a 996 throttle body, and an intake tube.
-You'll need to buy the TB by yourself, as I can't guarantee a used part (unless you want to buy it new... but at 360$ a piece I wouldn't).
-For the intake tube, you can easily make one like mine (no metal cutting needed), it fits perfectly. If there is enough demand I can find the 90° couplers in bulk, which would cost less and include thel with the plenum.
The bent tube itself is available on eBay.


If you have any questions, suggestions, or if you're interested, tell me


I hope you'll like it as much as you've liked the shifters!

I would be interested in helping I am just about to buy a 987 airbox and 996 throttle body and was planning to use a 996 plenum.

Well, I found my testers! That was quick!

I'm PM'ing/Answering you right now

Thanks!

Ben

[Ben006]

Done!

Here is a link for the tube I've used:
3" 76mm 15deg Aluminum Turbo Intercooler Pipe Piping Tube Tubing L 300mm | eBay

+ two 3" to 3 1/8" 90° bend silicon couplers

EDIT: First one is ordered !!

[Ben006]

Second one on the way for testing!

I've order 100 M6 nuts and bolts, that's enough for 25 plenums

Cool, I look forward to experimenting. My goal is to add at least 30hp from these mods. I have access to vivid racings dyno so I'll do a couple of pulls in a few weeks.
Then I'll do the install and let the ecm set for a few weeks then dyno again. Bang for the buck this is going to be a good mod.

[Ben006]

I'm really looking forward to the dyno results!

I just drove mine 2hours and had a little fun with it, it definitely pulls more than a stock boxster 2.7!

Next thing for my car will be to fix the timing... too much deviation :/ then put back some catalytic converters on the mid pipes and a tune... and I'll be done for performance upgrades!

[eddy]

Madmodz, are you a 2.7 or 3.2? I might be able to arrange for some before/after dyno runs on my S too. I'll call the shop this week. debating just doing the dyno for the plenum/tb or adding the 987 airbox i just got too...

Hey Eddy,
I have the 2.7 Vivid racing does a ton of Porsche work, and I was thinking of doing a flash too. I'm running 4 cats to straight pipes no mufflers. I want to delete two of the pipes and go straight. I really want to do a TPI stage 2 turbo in the future

[Ben006]

I received the first one!

It feel very good, they have gotten better with their 3d printers, there is almost no marks on it! I'm really happy with the result.







Now I'm going to smooth the inside to get rid of any loose particle and paint the outside to seal it (since I won't polish the outside).

Ben.

i'm no engineer, but it looks like you've designed a very nice piece.

I agree, it looks nicely made. Someone please give me the 411 on which throttle body to use. Years, part #, what not to use. Some ebay sellers are selling boxster tb's as 996 parts. They don't mention the mm size in their listings. I even saw one pulled from a 2.5 and being sold as a 996.

Thanks
I just designed it, I have to give credit to the guys @ shapeways for the printing! They know their stuff!

I'm done polishing the inside of the one I just received.
Still have to make sure it is clean and paint it!

I'm really excited to try it out. Thanks again for all the effort you're putting into these.
