IPD Tests 82mm Competition Plenum on Cayman R
Greetings again 6 Speeders,
We finally found the opportunity to perform some dyno testing with the 987.2 Competition 82mm IPD Plenum and the new Cayman R. Although the Cayman R offers a number of performance enhancements over the standard Cayman S, the engine remains relatively unchanged. The R delivers 10 more HP over the S but they share the exact same intake system from air box to engine.
The Cayman R tested was completely bone stock from bumper to bumper. The test was conducted the same afternoon with no changes in the weather while the car remained strapped to the dyno and the customer present during the entire test session.
The 987.2 IPD Competition Plenum requires upgrading the factory OE 74mm throttle body with the larger 82mm throttle body found on the 997 GT3. Our 987.1 Competition Plenum (Without a doubt IPDs most popular Plenum) required the same 82mm upgrade and has become the single best performance mod for any 987.1 application whether stock or heavily modded.
Stay tuned for 82mm Comp Plenum test on a fully modded Cayman R.
If youd like to learn more about the Dyno Test session and the 987.2 Competition Plenum then please click on the link below. Or as always drop us an e-mail or give us a call.

Im assuming that "stock" means, no intake or exhaust, but a software tune with the new plenum to get these numbers? Could you tell us which software you chose? thanks

The Cayman R was bumper to bumper "bone stock" just as it was delivered from the factory. If the car had any ECU/DME tuning performed it would have DEFINITELY been included in the article / dyno graphs. We conduct all testing and product evaluations on an "apples to apples" basis so we can properly gauge product performance gains.
The customer is contemplating an EVOMS ECU Tune down the road but hasn't pulled the trigger as of yet.
Thanks again for all the interest,

987.2 IPD Plenum Fitment
My apologizes for not addressing your question sooner.
The IPD Plenum is very close in dimension to the factory OE intake and has been designed to utilize factory hardware so installing the IPD Plenum should be VERY similar to installing the factory OE intake system.
That being said, it is still a relatively challenging install that should only be performed by very qualified DIY customers and Porsche technicians. Its considerably easier to install than the Turbo applications but not quite as easy as the earlier .1 N.A. Plenum applications.
Total time to uninstall the factory unit and install the IPD Plenum is approximately 2 hours total.
There isnt a lot of real estate inside the engine bay in general, but we havent had any complaints regarding the installation of our Plenum. You can review the installation guide on our website (link below) for a more detailed description on the installation process if youre so inclined.

How's the change in throttle response generally with your plenums? Rarely is it unaffected, but isn't guaranteed to be any better and can be worse depending on the variables. But here I would think better.
And why don't you polish the inside of your plenums? Even if you molded in plastic or ABS you'd get a perfectly smooth internal. The air can't tell the difference between metal and plastic. I keep thinking your sand cast interior can't be ideal for air flow.
Have you experimented with reed valves? Creating a swirling air flow can help too when it comes to a more efficient combustion.

Hi Greg,
What type of increase in HP and TQ would you expect from this plenum on a 987.1 2.7L Boxster? I know that there is no throttle body upgrade available for this car, correct me if I'm wrong? My car has a LP turbo kit and produced approx 295 at the wheels, but I am definitely interested in seeing what you would expect horsepower and torque wise by adding a plenum.
Thanks in advance,
Chris
