Pod Filters "What if?"
« on: February 17, 2011, 12:08:26 PM »
Just on a vacation to New Orleans and during my many nights of drunken stupors I had time to contemplate the many wonders of the real world.  I read several posts of cafe builders wanting to build using Pod Filters, but many believe them to be a biitch to tune.  I read one very informative post giving highly theoritcal reason as to the cause of this, which I suspect to be valid.  This and the drunken stupor, lead me to think, What if you were to use the common Pod Filter but fashion a velocity shaped stack to sit inside the filter and be held in place by the flange which mounted over the carb mouth.

I could see using a thin sheet of tin fashioned into a cylinder and soldered to hold its shape.  As long as the cylinder is shorter than the filter is long the air would still be drawn from the full surface of the filtering material yet the shape of the cylinder would lengthen the throat of the carb, possible increasing the size of the vacuum allowing for more appropriate fuel draw from the stock jetting.

What do you technical gurus think, should I continue to drink and save thoughts for more benefical topics like whether the waitress wants me or not?

How long is long enough to reduce turbulent flow? That is the question.

I don't have the original air box, so I don't know what the length of the runner was.  A pod deletes the runner and leaves the carb mouth as the runner. My thinking is that the makeshift cylinder could end up being 2" long depending on the Pod length.  I would hope that the air flow would dramatically improve in that length over nothing at all.

it depends on a few factors. What is the waitress wearing? ;D

the other question is by extending you have to remember the 2 outer pods without being extended hit or barely hit the frame

Seen both of those concepts, but I was thinking more for those that had Pods already and a simple way of correcting the downsides of the lack of intake runner length.

i like your thinking
there is only one way to find out
they say a slight swirl motion of air just before the carb may help too
