    Default Engine Analyser Pro

    Might be of interest to someone. Anyway it's free.

    Cool used to cost money. Thanks for the heads up.

    Edit: It's not free, still needs to be registered.

    Have no time for penis enthusiasts who are full of opinions and no real clue.

    yeah i know but get around it by keeping the save file and reinstalling it.
    or maybe this one
    Virtual Engine Calculator Free Download

    there are the full apps out there but you know.. torrents are illegal man...

    Pipemax is the best engine program there is, it doesnt predict power output but all the other calculations like demand at peak piston speed, curtain area, choke RPM etc are on there which you could probably work out on a calculator but this takes seconds. Well worth the asking price, its not that expensive...

    I had a quick look at that. Does it show piston speed at any point of crank rotation? I’m running a 6 inch rod which apparently means I can close up on overlap a little bit.

    a longer rod would give more pause at the top as the rod swings across before beginning its descent, quite an academic thing really.

    Yeah definitely. I'd just like to know how many degrees that happens for, and then piston speeds to suss out CFM and air speed at certain points of rotation. I know I can sit down, draw it to scale and do the math. But if the software does it, I can find out in an instant and also get a better idea of what my pipes and collector sizes are doing.

    While the missus watches Midsomer Murders, I prefer to stuff around with this kind of thing. All good fun.

    doubt the software does it, hows your Trig? it's probs 15 to 17 degrees.

    ok holden v8 would probs benefit from a 6 inch rod lol.. use a 6 inch rod from c.o.m.e and one of their pistons should get you there.. give them a buzz.

    Nice! That'll do just fine!

    Already have it all on a 355 crank. Running. Just need to get it regoed and on the road!! lol

    Yes, here it is for a 355 Holden at 7000RPM with a 6.0" rod.

    Piston CFM Demand = is the Piston CFM @28 inches the Engine really wants
    Intake System CFM = is what you say your Engine is accessing ,
    you are saying this by your 107.00 Volumetric Efficiency % input

    Crank Intake Piston Piston Piston Volume Crank Rod-to- Rod-to-

    Yeah I know took up some real estate... Try doing that with a calculator, you'll be there for a while.. Also shows peak CFM demand at max piston velocity, piston depth etc..
