You want to pump out stuff from a chest at a fast rate? Either switch to redpower with filters/pneumatic tube, or power a wooden transport pipe next to the chest with an energy link powered by a constant 10eut (a generator would work), and that would pump out 20 single items per second.

Or another little known trick you can do if you want to pump out stacks extremely fast, do the above wooden pipe solution, except use a turtle as the "chest". Certain other nonchest inventories work also, like the inventory of a filter. Now, power the energy link with 2 hv solars, and it will then pump out 20 STACKS per second.

Seems like turtles don't have that 1 item per tick (20/sec) limit to them like chests do, which allows you to pull items extremely fast.
