I did not want this mod. It does not make any logical improvement to the engine intake. That area of the circut is under boost . . so who cares what the flow is? The porsche plastic looks stylish and smooth. And if you could get a few more PS why did porsche overlook it.

Then Gary at Road Sport Supply extended the christmas sale. And I can't say that I recieved any truely nice presents for all the "good" stuff I did all year. Gary also said if I wasen't impressed that I could return it.

The UPS man delivered it. And I installed it in about a hour, saving the box because I knew that the return was comming. I started her up; still fuming that I had spent all this time and money on something that will not make a difference. I was wrong.

Most people are saying there is a "big difference." I will agree. This makes the Cayenne Turbo into a 'fun' suv. Don't get me wrong. 540 horses makes a rocket that pulls strong until redline, but at that speed you are endangering your life, your license, and alot of people around you. This Mod makes the engine more responsive when not under boost. Little to no lag going into corners. The nose jumps off the line at a tap of the throttle.

So I was wrong. I feel that this is a required Mod that I should have done when I purchased the CTTS. I still cannot explain it, but the butt dyno is impressed.

 

you don't "have" to floor it all the time knowing that you "have" the power in your hands is why we mod our cars

 

I love this post BM, it talks to the cynic in all of us!

I spoke to Greg too, and f it wasn't for the Canadian dollar right now I would have bought one too.

Still waiting....

Oh yeah, and "this post is useless without pictures"

 

Thanks for the post. I just picked up my plenum and waiting to install. I hope it's as good as all the hype!

 

am getting mine soon could you post a DIY guide ?

 

Has anybody done a before and after dyno with only this mod? There have been a lot of discussions on the 997 Turbo area of this plenum. Real mixed reviews there.

 

Here's the step by step install of the IPD Plenum. It took me about 45 minutes due to finding the right tools.

1. Remove top cover then remove MAF sensor



2. MAF sensor removed


3. Twist 180 degrees the two screws shown here and pull out.


4. Loosen the hose clamps on left and right of plenum, pull hoses off plenum then carefully twist stock plenum off of intake; then remove bottom hose off of plenum.




5. Stock plenum removed


6. Interior view of stock plenum


7. Interior view of the IPD Plenum


8. Install IPD plenum


9. Reattach bottom hose and right and left intake hoses, tighten hose clamps; reattach MAF sensor.


10. Reattach top cover; job complete.


I took it for a spin but didn't notice that much of a difference from stock.

 

Nice pics / write up ... but who the heck is Turbo Mike Performance?

 

Interestingly the pictures Kimo posted up show the inside of the stock plenium looks very similar to the IPD one. Unlike the 996T Plenum wich T's off the Cayenne Plenum already has the "Y" configuration. (at least it seems like it to me) If the plenum "T's" I can see the benefit of this... but seeing these pictures leaves me a bit skeptical...

Anyway... does anyone know if the inside diameter is larger than stock? Also if the stock PLenum is a "Y" configuration just like the IPD piece what is the actual benefit of the upgrade?

I would love to ad this to my CTT. But for $1K I think I'll wait until I can get verified dyno results or some sort of explanation. FWIW the IPD piece looks MUCH better asthetically than the stock plastic....

 

thanks Man Reps for u

 

I don't know but maybe RSSGreg will chime in and enlighten us.

 

Might be referring to Turbo Performance Center? Mike Levitas ownes it.

Turbo Mike and IPD is the same person. As far as the difference b/n the factory plenum and IPD plenum, here is the facts: 1-it was desinged from aluminum cast not to split open like factory 2-Larger inlets on IPD design for more air flow 3-IPD plenum has a better diversion than stock plenum therefore diverting more air flow and air speed. 4-by getting more air flow then more throtle response as well as boost response all the way to redline. RSS has all the facts with dyno proven results. Not to mention, money back gaurantee. BTW don't mess with Turbo Mike, he is my cousin.

 

Thanks very much for the write-up and pictures Kimo!!!

Yes looking at them both they look very close (other than the ribbing for her pleasure)

Kimo did you have a look inside those expansion things on both sides, I would like to know if they have a tube in them as well or just billows like on the outside?

Cheers,

Bob

 

Okay Turbo Mike is your cousin, so then who the heck are you?

Thanks for the info on the IPD vs. OE plenum - good to know.
