Default bfi 3.4 air chamber

question i did this mod with a kit off of ebay an got good power gains an it also stop the off the line gag but i have a question about the new created air chamber. i noticed that when the car is not moving the off the line pedal response was not as responsive as when car is moving. can u tunnel air into the chamber with fans pushing air into chamber say maybe on the side by the battery just to keep a small flow of air in chamber at all times. not alot but just enough to keep chamber full

Man it sure would be easier to read this with correct punctuation and capitalization.
Anyways.....
I just installed the kit that I bought on ebay. Although I got the 3.2 kit (didn't want the badging and crap). You say the car isn't as responsive off the line, I haven't noticed this on my brother's SC400 I put it on. What you are saying would slightly help but the cost and time of doing this wouldn't be justified with the very minimal gain. Just make sure you installed all pieces and did everything correct. Also it shouldn't have changed because before with your stock intake system no air was being forced into the intake at idle as well. The actual snorkel allows for very small amounts of air to be fed into the intake.

Also, no need to post this in two sections on the forum. It's performance, so it goes under the performance section.

There's no "ram-air effect" when the car is not moving; therefore, there's not a significant gain. I would leave it as is, no need to add extra stuff, too many things to go wrong. Keeping it simple is key.

Yeah a turbo-charged system basically does what you are asking, only 100 000x's more rpms of revolutions in intake. Fanning the air into the chamber will not make much of a difference because the pressure will still be the same. And when the intake is only forced by the pressure of the engine, the density of the air will not increase. It will be the same.
