Power Ducts don’t work, here’s why
I just got off the phone with Patrick at Vararam; I’ve never been on the phone with any one for more than 1hr. I was on the phone with him for almost 3hrs. This guy is the most knowledgeable person I’ve ever talked to about mods. Everything I asked him he was able to pull hard tested number and in most cases he had numbers from a out side source.
Cartek and the company that makes Vararam have dynode and road tested several power ducts and they don’t get you any more hp, Cartek found one that did get you 4 more hp under curve not peak hp, not that good when your talking about 250.00 product. The aftermarket power ducts do deliver more air but with fuel injection port velocity is king. The duct is bigger witch slows the air down and drops the air pressure, it’s like when you have a straw and you blow threw it the air coming out is moving fast as your pushing the air in, but with a bigger power duct your making the straw have a big center section and then shrieking it back to the stock size witch doesn’t do anything for you. He said you should get ride of that according air coupler that goes form the power duct to the TB. He said the stock works just great and there are better places to spend you money.

Yep - they have been generally accepted as an appearance mod - :D - cause the stockers are just to plain for such a sweet ride! :jester

Sorry I didn't ask but I know from talking with other people that they only get 2hp gain and some times it doesn't even show any gains with a dyno. But it is common since that air would flow better with it so it can't hurt, only 40.00-50.00 so you’re not out to much.

if it's only cosmetic... for the price of a decal set (and a can of clear coat) one can dress up the stock air-bridge quite nicely :)

Okay, I'll admit it. I just paid $227 for my carbon fiber power duct with the 405hp Z06 emblem. Together with the Blackwing, the difference was noticeable. Obviously due to the Blackwing. But it looks so good! Plus I shaved off a good 12 to 14 ounces going from plastic to carbon fiber, so my car HAS to be faster. :lol:
PS, I bought the power duct for appearance only. :seeya

We have been talking about this for years. We know that the duct is just for looks, yet we buy them anyway. :)

I too bought the powerduct with the Blackwing. The powerduct was an appearance only mod. . .unfortunately, I am now selling it with the Blackwing so that my supercharger can be installed.
I decided that the powerduct wasn't letting enough air into the engine. . .so I had to switch to forced induction. :lolg:
