Anyone know where I can get the values you need for Desktop Dyno. I'm bored and have the program but have no clue where to get the information to fill in all of the fields. I'm looking for stock head flow values (and ported stock head.. thats one of the mods I'm looking into), Valve sizes, Induction flow (cfm), stock turbo: flow, efficiency, pressure ratio, surge flow??, Intercooler efficiency (Stock) and finally stock cam specs. Just figured I'd run some numbers but have no clue where to get them from. TIA
