2TBdemo from "Softengine" ( Italy )
Full running except 68cc displacement and 9000 rpm max . Download démo in English pages .
In 5 min , you would create a power curve of a 68cc piston ported first and be able check many other things : - TimeArea - BMEP - waves we would explain later . You would be able then to start your own computations .

Dm2demo from "Dynomation" ( USA )
Run with 125RM 98 engine . DOS app too , a great simulator that show you exhaust waves in pipe during work . This is much better than to read tenth of text lines on subject ... I haven't time to write ... see "book links" .

Optimize from "P.B Havellar" ( NL )
From very first G.P Blair , DOS simulator for piston ported engine , very simple but like all others run ... if you can't run this one , don't buy simulator but a database like TSR . A good tool for oldies owners . I recently found how to cheat and run reed valve engine on peak power , still some job to check ( thanks Mr MBX - NL ) .
