rHMT Filter Velocity Stack
« on: May 02, 2009, 02:35:55 PM »
I'm thinking about making my own velocity stack/base for a K&N cone filter. Bottom line is I want a 4" inlet filter for a possible 4" inlet turbo, but have 3" atm. I just can't find shit for bushings, nor do I have space for normal reducers. The 4" K&N's also have a size selections for my current space restrictions, as my topmount puts it right where a Civic's PS reservoir normally sits.

I'm thinking about using a section of 3" and 4" aluminum tubing, with 1/2" alum TUBE as the rounded part...Devcon'd together (JB weld for alum), ends flared & smoothed out. Anyone every try an idea like this?? (red by tubes is the devcon)



This is the filter I plan on using if anyone cares

I was wondering about making velocity stacks for a ITB setup myself and I was wondering about Devcon or some other Aluminum epoxy.

Or is there a cheap source for velocity stacks?

I remember reading something about an idea velocity stack design.

Something about taking the dia. of throat D.

Then flair the edges out along radius D.

And end up with a total dia. being 3*D.

I read that in Maximum Boost by Corky Bell (best turbo book ever :yes:)

I found this link a while back, has some cheap v-stacks, appears to be nice quality too:
http://www.velocity-of-sound.com/velocity_of_sound/velocity_stacks.htm


I'm looking to make it more of a bushing, so I don't have to buy a seperate 3" and 4" filter. I do have a Holset HE351VE with a big 4", just not sure when I'll use it.

I think all cop cars need to have turbo. nbspnbsp Then they would understand the necessity of putting your foot down and how uncontrollable the urge is to fucking rail on that shit.
