Can you simulate my engine?
I have a 289 Windsor which I plan to improve but I'm unsure about a couple of things and would like some engine simulations done.
Could somebody please simulate my engine with both of the cams listed below using both a 525 (BG Road Demon) and 575 (BG Speed Demon) (4 simulations in total).
It would be appreciated if you could post up the 4 simulated power and torque curves for me. I am only really intereseted up to 4000rpm.
If you can suggest improvements to improve the power a torque curves below 4000 rpm it would also be appreciated.
Sorry to ask so much.
The details of my engine and the cams are as follows:
