Hi! Darin
I have a Bell Intercooler fitted to my 914 and have no hesitation
whatsoever.
I can't point you to a cure for your problem but it looks like it wasn't
the intercooler at least.
Do you slam the throttle wide open or advance it more deliberately? It
just may be temporarily flooding the intakes.

Ivor,
The wastegate travels through its full movement without binding and so
do the throttles.
Herve,
I will check these again but they seem to be good.
Paul,
It seems to be the same with one or both boost pumps running and fuel
flow is good. I did have an issue with a plugged fuel filter at about
20 hours but that has been replaced. The plugged filter obviously
caused significant hesitation and rough running, so much so that I
couldn't get much more than 4800 RPM. I also installed the Bell
intercooler which I had to modify for my installation by cutting and
rewelding the outlet 180 degrees to its original position. Apparently,
this modification changed the airflow characteristics just enough that I
was not getting the air I needed and the engine would hesitate and
sputter around 5000 rpm. Both the filter problem and the intercooler
issue have been remedied by either replacing or removing the items. Now
I just have the very short single hesitation described in the original
post before it goes WOT.
