Fluid Guru?

Seen as you are "the meat" when it comes to fluid dynamics there is one thing i have been thinking about, now if we can make out fluid flow through the pistons in a laminar flow rather than turbulent then surely they will work more efficiently. I have thought also that if we tapered the holes slightly (but not open the holes any wider, Hard to do i know) then i think this would work to a point?

I dont know if this has been tried before or maybe i am just talking crap, what are your thoughts or findings?

Xray already have tapered pistons for their 1:8 rallycross buggy

There was me thinking i was clever


What were the findings then?

[Chris Doughty]

turbulant flow is a tuning aid.

its not a matter of making them work more 'efficiently' turbulant flow is good to help 'soft' damping pack up when landing a big jump.

small holes + light oil work well on tracks with big jumps.

big holes heavy oil work well on 'rippled' tracks

Ok cheers chris,

So there is no point in tapering a hole?

[Chris Doughty]

if you think it would give you what you wanted...

personally, I can reduce pack (or turbulant flow) enough using heavier oils and bigger holes for what I need.
