Hi all,

I'm helping a team in the Thai Endurance Racing Series running a Honda City with an L15 engine. We have two engines, one with more power than the other, and we're trying to figure out the difference. We have stock cams marked "S1", "S2", "S3", and "S5", and want to know if there are any differences in the profiles among these cams. The more powerful engine has the cam marked S5. In this class the cam profiles must be factory, although updating and backdating within limits are allowed. Haven't been able to find anything by searching the web. Does anybody know anything about this subject?

Thanks in advance,

-JJ

 

Very interesting, sorry I have nothing to add to the topic. How big were the power differences?
