Thread: Smaller version of bpi/blox velocity stack

Hey guys.

I need a velocity stack that is around the 3" Inner diameter size, but with a smaller outer radius than the usual 6" of the bpi/ blox stacks. It's is because I have no space or such a big air filter.

Anyone know of such a stack that exists?

Thanks

Not that I know of but they make all kinds of different sized filters.

yeah problem is I dot' have space for the filters that accept the normal velocity stacks. The application requires a smaller filter, but I still want a flow stack inside it.

This?

Thanks but both of those have 6" bell mouths. I need say 4" or 4.5".

Ahhh, shoot. Gotcha. How about these guys? If they don't have it, they can probably produce one to your needs.

The link above has 5" outside diameter setups...

Home - 3" OD - 5"

You might be better off buying a filter designed for a 3" pipe with a built-in transition. I believe those are not too hard to find.

That alone gave me a few extra ponies vs no filter on the dyno! S&B Filters has them readily.

Thanks guys. That jnt option above is perfect.
