Fuel system calibration
is the key to performance and drivability, so, besides building
an understanding of what affects performance in all kinds
of engines, we use the dyno to 'finish the job'. Which is
to say, calibrate the fuel systems (carbs as well as injection)
and adjust the ignition timing to get the power out of the
engine design.
These dynamometer charts
aren't intended to be the 'last word' on any particular subject,
but we will try to show the effects of one change at a time.
One reason that there is
so much misinformation floating around, is, that most of the
time, when a person is having her/his engine built, it is
common to have several modifications undertaken at one time.
(One can't afford to do the job three times for three components.)
Without one-change back-to-back testing, the effects of these
modifications are 'intertwined' and it is hard to separate
the effects of each, on the whole result.
If you have any specific questions,
drop us an e-mail
or give us a call.
All of the really impressive
results (not all of the results are impressive, some are)
in the tech reports that follow, are the result of a lot of
time, and care, and fiddling, and lots of dyno runs.
Good results come from hard work and good testing. When you
buy a jet kit or a 'chip' for your bike, and install it yourself,
sometimes you get good results, and sometimes you don't.
