This topic has been discussed at great length here at IPD.
As always, we perform 3 tests on 3 separate same model “bone stock” cars to evaluate all IPD Plenum applications. This provides a accurate gauge of performance gains and validates our products as being an after-market performance part worthy of being installed on a Porsche.
This being said, our testing of “modded” Porsche’s isn’t nearly as extensive and doesn’t provide an “apples to apples” comparisons since every modded car is very unique with it’s own variety of mods and running condition.
But the bottom-line is that the patented design of the IPD Plenums is what delivers the bulk of the power and torque. Combining the IPD Plenum with a larger TB has yielded minimal gains on bone stock naturally aspirated Porsches but does deliver improved gains with more heavily modded Porsches.
Our “Competition” series Plenums are specifically designed to work with cars equipped with high quality / high flow exhausts whether is be a kat-back or complete system. Without the high flow exhaust the extra $350 for the TB isn’t really a worthwhile investment.
Now our most popular N/A Plenum applications is without a doubt the 987.1 Cayman / Boxster 82mm Competition Plenum. This application upgrades the factory 74mm TB to the largest GT3 82mm TB. But definitely requires a quality kat-back system to optimize the larger TB. They go together like peanut butter and jelly.
We are currently in the process of developing a brand new version of a 997.1 82mm “Competition” Plenum. This should be available in the next month or two. As always we would like to perform our tests with a couple of seasoned and well respected 6 Speed members who reside in the Southern California area, preferably in Orange County. Unlike so many other manufactuers, we ALWAYS prefer the customer to be present during all tests so they can provide an unbiased and objective evaluation of the Plenum to the 6 Speed community at large.
It doesn’t matter if the volunteered Porsches are equipped with IPD Plenums or not. We will test both 74mm and 82mm versions and post our findings for all to see. Please drop us an e-mail or give us a ring to RSVP. We look forward to sharing our findings and shedding some light on this on-going subject.
Cheers,
IPD Greg

How about an even better solution which does not void warranty:-
X51 throttle body - larger than stock and designed for our cars so no warranty issues
X51 plenum - again original Porsche so no warranty issues and is polished for improved performance.
Then also the X51 air intake distributors (manifolds) again which are polished for greater flow.
This is all Porsche original and with proven gains plus the cost is circa $3000 for all this or just circa $1200 for the x51 tb and plenum.
Has anyone done or thought of the above?

I am not assuming, I am 110% correct.
I have in writing the following from Porsche:-
1. Is the part a Porsche genuine part?
2. Was the part fitted to Porsche standards?
3. Was that part originally intended for your model of car?
The answer is yes to all of the above!!
I have a 997.1 C2S, the X51 powerkit was an option when ordering the car, I am now looking to retro-fit parts of that kit as I've already done.
So far I have PSE, X51 manifolds, X51 radiators, X51 undertray and Porsche put a warranty on this car and informed Germany if it was OK with my mods, Germany came back with the above.
So I fail to understand where you are coming from?

Anyone can do the work as done to Porsche standards with Porsche genuine parts.
So Porsche or a Porsche specialist would be ideal.
Upon further investigation though this is not quite as easy as it seems, the air intake manifolds are a requirement which add several more hours labour.
Plus the hose which goes from the stock airbox to the stock throttle body won't fit over the X51 throttle body and as such a custom hose would need making.
Its at this point where Porsche may request you also fit the expensive carbon fibre airbox in order to use the original Porsche hose, sticking to genuine parts, at this point its getting very expensive.
So am doing some investigation as it may simply be a case for 15BHP this kind of expenditure is simply not worth it.

New 82mm Carrera Plenums available in January 2012
Season's Greetings 6 Speeders,
Yes, it has been a while but that is because we've done a complete ground up development effort with this Plenum. This is NOT a slightly revised or modified version of our standard 74mm Carrera Plenum that utilizes the factory 74mm TB but a brand new Competition Plenum from IPD.
Click on the link below to learn more about our latest tests.

Sorry for the unusual "delivery time" with the new 82mm Carrera Plenums but this Plenum has required more time than expected and involved a few different versions during the development process.
Season's Greetings from IPD

Have the full x51 mod retrofitted? No one ever does this. It is impossible to get the full kit retrofitted by a dealer or indie shop for less than the excessive price you would have origionally paid from the factory. The heads are a big part of the problem. Most look to install part of it themselves to save labor. This is where the issue of "to Porsche standards" becomes a warranty concern. If you are going to do a throttle body/air box/plenum mod in your garage you might as well go for max bang for the buck and go the GT3 route. If you have subsequent problems you are on your own with respect to repairs anyway.
Now, on a used car with prices being around low to mid $50k on 2006 models and even more on 2007-08 cars, I'd take the $15k or more it would cost anyone not fortunate enough to get a discount and add it to the sales proceed on the car and just get a 2009 model. Getting the full X51 nowadays only makes sense by buying a car with it already.

BTW, though the kit carries the Porsche warranty that applies to genuine replacement parts, the dealer assured me that the car's original warranty would be honored. I took my chances back then and have no regrets; my car now has 42,900 miles. The tech that did the installation had done a few X51s on 996s though mine was his first 997.

Sorry but this is not accurate. I had the full kit, including heads, retrofitted at my local dealer and never had an issue. I had this done when my car had a little over 3000 miles in 2006. If the motor has over 25k miles, there is additional work needed on the bottom end and then it becomes a lot more expensive. I ended up paying just below $14k, labor included. It's true that I get a very nice discount at my dealer from being a long time customer, so I took that into consideration. The kit is not retrofittable On 2005 models.
