Suggestions for Velocity Stacks?

SouthArk370Z

The stacks shown in the second pic of the OP look like they might do some good. What you show in your last sets of pics looks like it would interfere with the flow. But I'm not an Aerodynamics Engineer (or Engineer of any sort). I'm looking forward to seeing your results and hope that my guesses are wrong.

A big dowel pin reamer may give you the taper you are looking for but not sure how it would work on plastic.

Jordo!

I think it all comes down to how much of a restriction is the filter. The lip of the bellmouth in it's current position just barely touches it. Otherwise, it has a direct path to the entry way on the airbox duct, maintaining the same "line of sight" as the OEM neck, just extended.

I'm hoping to recess the thing in by a few inches so it will be less of an issue. That might even give me enough room to just keep the OEM filter location, instead of having it sit a bit farther forward.

On that note, I'm not sure if filter position will make a difference either...

I'm committed to this experiment now, so win lose or draw, it will give me some useful info on what to do next (e.g., have even shorter v-stacks made) or whether to abandon the project entirely...

BTW, thanks for all of your input -- I very much appreciate it

The portion of the airflow that is to the right of the stack in your pics doesn't look like it will have a straight shot to the stack unless the stack is a lot shorter. Can you cut the stack to make it shorter? That would avoid a lot of "machine" work on the plastic parts.

I don't think the position of the filter will have much effect on flow but it certainly would be a lot easier to R&R if it were in the original position.


Hang in there! This is one of the few time I'm hoping someone proves me wrong.
