Playing with the CCR is a software cheat , but it can have all sorts of bad effects when you are trying to improve on the baseline.
It means the baseline is wrong from day one.
If the sim is optimistic down low , I would be looking at what does change , in reality , during a dyno pull.
The egt , and thus the pipe wall temp will vary considerably.
In nearly all the race engines I have worked on , using 325* below the pipe and 425* at peak power gives great realistic results.
For a "stock " engine the numbers can easily be adjusted to change how the sim reacts at very low rpm by simply changing the wall temp.
The software interpolates beween the two temps , so you can add as many jump points as is needed to reflect reality.
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.
