Am I the only one mad enough to design and 3d print my own velocity stacks?
Sorry for tiny photos...thats the shitness of apple products not allowing me to copy image location.
The white one is a 3" to 6" spherical - Mark1.
My car made 220bhp with this on.
Blue is an eliptical design that is as close to the perfect profile as is possible with a 3" to 6" constraint. Ideally you need about 7" to feed the 3" outlet without separation of the flow.
I will try this one next time. i have a dyno run.
Both are 3D printed on an Upbox and modelled by me. I am using a forge 6" filter which is why there is no outer radius - you would need this without a filter at all.
