Ducati 999 Development
________________________________________________________________________
This project represents our first
attempt at a full race type rework. The baseline numbers were taken
on a 100mm bore while the finished numbers were measured on a 102mm
bore. All flow figures are in CFM @ 28” of water test pressure.
(These are industry standards).

Note: All exhaust flows were taken
with a Termigoni 57mm manifold attached to the head. Valve size was
stock but our profile valve was used.

 These
photos show various views of the custom fixturing we built to
accurately perform repeatable flow tests. Fixturing like this is
necessary to prevent testing errors from influencing development.
While many people omit this important step, we feel our results justify
the effort taken.
These images show detail of the completed heads. Flow figures are listed at top of page.
These
pistons were custom made to our specifications by CP Pistons.
Bore was increased from 100 mm to 4 in, compression raised from 11.4 to
12.7. A close examination of the underside views reveals
extensive internal milling needed to produce a finished weight only 5
grams heavier than the original pistons despite the overbore and
dome. We were blown away by the quality of these parts.
The following pictures detail degreeing the camshafts during engine assembly. Special tools are shown.
Here
we have the reassembled motorcycle. This shot was taken at BCM’s
shop in Laconia, N.H. while the bike was being fitted with a
Power Commander prior to dyno tuning.
Ducati 1029
Dynograph showing test results from most recent 1029 cc Ducati
(2005 999 engine)
This
engine utilized AFT modified heads with special valves (42mm intake)
AFT custom pistons, (13.4 to 1 compression ratio), Squish set, cams
degreed, 57mm Termignoni exhaust as well as 12 hole 999R
injectors and “kit” velocity stacks from a 749R racing kit. Call
for further information on this and other Ducati combinations.
