Has anyone had any luck simulating a B18C5 engine using Dyno 2000 by Motion Software? The software only supports single profile camshafts so I guess you'd have to run 2 simulations, one with VTEC off, one with it on. Any help on the engine specs would be appreciated.

Thanks in advance.

The specs I'm interested in are as follows...
bore (mm),stroke (mm)
Cam Timing Specs (@seat to seat)(or at .050-lift)
for both VTEC on and off:
Lobe center angle (cam degrees)
Intake duration (crank degrees)
Intake lift @ valve (mm)
Intake centerline (crank degrees)
Exhaust duration (crank degrees)
Exhaust lift @ valve (mm)
Intake and Exhaust valve diameters (mm)
Intake valve open (BTDC)
Exhaust valve open (BBDC)
Intake valve close (ABDC)
Exhaust valve close (ATDC)
Compression Ratio
Air Flow @ 1.5 in Hg
See diagram on page 35 of manual for the following:
Head chamber volume (cc)
Head gasket bore (mm)
Head gasket thickness (mm)
Piston down from TDC (mm)
Volume above piston (cc)

I recently dyno'd my car (and posted it on this site) so I'd like to compare, and to play around with the cam timing. Theoretically it could save a few bucks during tuning, but mostly it's just for fun.
Imperial units are ok too for my cousins to the south.
