Sorry guys but hasn't this plenum been proven to not show any gains? There are several posts on the 997 forum where a member gave his car to AWE Tuning, they tested, found no gains, asked RSS for another one and tested again and at the end of the day it made next to no additional power. ?????

Sure as heck ain't worth a grand!!! The concept makes no sense at all for NA engines, as the air is SUCKED in by the vacuum of the cylinder, so it will travel the shortest path. As the stock plenum is already ID radiused, there is no change in flow velocity, PLUS you lose the reflected pressure wave reinforcement that is designed into the OEM intake plenum.

Yes, we know, this event is a result of the AWE dyno. I drive a 996 and would like to see what happens on cars similar to mine.
Here is the thread at 6speed 997 forum from AWE with dyno charts. Smoking gun? Post #71 for the impatient among you.

I love how the dynos prove what I said all along>>>>>>>>>>>>no gains 
The factory intake is way way way way way larger than it needs to be on a 296-320 hp motor.
Porsche did their homework..........

More tests can't hurt.

I'll find out today. We're are dynoing with and without on the 996. I'll post the results.
