Data

At this point, I have 25 data sets.
1. Base or stock configuration
2. Advance intake valve opening 7.1 degrees
3. Advance intake valve opening 14.2 degrees
4. Retard intake valve opening 7.1 degrees
5. Retard intake valve opening 14.2 degrees
6. Advance exhaust valve opening 7.1 degrees
7. Advance exhaust valve opening 14.2 degrees
8. Retard exhaust valve opening 7.1 degrees
9. Retard exhaust valve opening 14.2 degrees
10. Increase intake valve diameter +5%
11. Increase intake valve diameter +10%
12. Decrease intake valve diameter -5%
13. Decrease intake valve diameter -10%
14. Increase exhaust valve diameter +5%
15. Increase exhaust valve diameter +10%
16. Decrease exhaust valve diameter -5%
17. Decrease exhaust valve diameter -10%
18. Increase intake valve lift +5%
19. Increase intake valve lift +10%
20. Decrease intake valve lift -5%
21. Decrease intake valve lift -10%
22. Increase exhaust valve lift +5%
23. Increase exhaust valve lift +10%
24. Decrease exhaust valve lift -5%
25. Decrease exhaust valve lift -10%
I also restricted the output to look at to between 4500 and 7000 RPM in 500 RPM increments. That totals 150 datasets.Due to the basic engine design, I knew that peak torque and horsepower would occur in that RPM range. Also, I separated torque and horsepower as two distinctly separate result goals. Why? Well, usually to achieve the maximum of either requires different configurations. Adding valve diameter and lift also makes the test more valid as it definitely complicates that data and adds more possible contributory factors.
Time to run the data. I'll post the results next time.
