I saw an ad in a magazine and then checked their website, they claim to make 25 more hp out of their Intake Plenum. They don't have a dyno to support their claim (at least not on the website). Does anyone have one? Is it possible to get that much power out of an intake plenum?

lots of dyno info and discussion on these already. i installed one and there is a noticable increase.

deputydog dynoed the part and came back with good power gain results.

 

Here's a start... you can do the rest of the legwork...

Its been documented by lots of guys here. It works!

 

Cool thanks guys, hey ZEMDOGG where is the Porsche dealer in Orlando? I use to live down here and actually down here on business.

 

^^^ It's in Maitland on 17-92. Right up the street from the Benz dealer. Im off tomorrow but come on down Wednesday or after : )

i have it... i like it......never dynoed. but seems faster..... then again, if i stand in front of the fan and close my eyes, i think im moving.....

 

Alright cool, yeah I know where that's at now. I'll see if I can get some time to stop by on Wednesday.

Thanks,

Now Thats funny.....And Oh the plenum helps more with mods

 

Here's a before and after dyno. I saw 28HP, 26Ft-lbs - mid-range gains.

 

Interesting graph......is that with stock airbox? Any word on how it is with modded airbox on top of it?

 

wow that is NICEEEEEEEEEE!!!!

 

Do not buy this product, seriously.......it only enhances a 996 and you will not be happy......especially if you have EVOMS and any other mod.
Funny my dealership now recommends these to every 996/997 owner

 

Am I the only one that can't make sense out of this?

 

Doesnt make sense but works...
