ID:	336217 real life dyno run of the engine being modeled, (rw hp) .

    The EngMod simulation is starting to look like the real thing. I will refine the model a bit more then Wob can work his magic and hopefully let us in on a trick or two.

    I run the rear tire on a 1.6" rim
    And the front tire on a 1.2" rim

    Simple Dutchpower - in the Temp page you have not simulated the pipe wall temp correctly.
    The new rpm dependent inputs now also have the opportunity to enter the real ,as measured, surface temp data from the header,the mid, and in front of the stinger.
    As the bmep reaches the outer limits, as in say a KZ2 engine, at 50Hp from a 125, the smallest changes in this type of data, make big effects on the result.
    That is Bullshit in = Bullshit out.
    For many tuned engines I have found that a global average temp of 325*C at the bottom of the powerband and 425*C at peak is a good start point,when the tuning gives low to mid 600*C inside the header.
    The other issue is the correct modelling of say a step in the header flange.Just putting in the dimensions to correctly show the position of a step is not the same as defining
    a step properly in the opening page of the pipe inputs.
    The code has a very difficult time handling steps ,and not defining them correctly creates havoc in the results.
    Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.

    I'm racing 50s here in Europe, it's pretty rad. I also got to meet Frits finally after reading so much of his advice online.

    Chris how do you get in these situations? I would love to have been in those pits with all those 50s.
    I guess they make our efforts look a little shaky.
    I've been told. Dreaming`s free.
    Think I'll go, back to sleep.
    Everybody listen, voices in my head
    Everybody listen, do yours say, what mine says?
