Go to utube and search for IPD and you can see dynos for many Porsche models without turbo. Guys, no one is selling here. Just sharing information. Man this is a tough crowd. I recieved one of Pedro's plenum but did not install it and frankly we are talking about two different quality of products I had them both in my hand last week. Have a Happy New Year and relax.

Problem is, the data available comes from individuals or firms with a “vested interest” in seeing the product succeed………. What it needs is independent evaluations by a credible source outside of the product’s marketing chain. To date, I have not seen that, so the plenum remains an “interesting, but unproven concept”…………and a damned expensive one at that………...

I know that I am just one case of these products but there are other real numbers out there from independents that show that these products actually restrict airflow. The chamber is actually smaller than OE design.

I stopped reading after I read "I haven't dyno'd yet".

btw, 50K miles on my 986S, many autox's and I've never once felt that my car had restrictive anythying. That's why I bought a P-car in the first place!

Mine has restrictive leg and knee room!
Then again, that's because I'm 6'1" tall.

This was a plenum that was manufactured in Spain. It was called the "Techno Toro". Unfortunately, early dyno testing proved it to be very restrictive.
