Stock cam data?? HELP! Need to compute DCR
« on: June 04, 2010, 09:08:38 PM »
Can anyone validate if these are correct. I found them at http://www.e30tech.com/forum/showpost.php?p=748554&postcount=39. Interestingly, Metric Mechanic's specs for the stock exhaust timing is 41° BBDC / 7° ATDC which is clearly different from the above spec. They did not, however, say whether it was the E30 or the E36.

E30:
Intake Open / Close
  • 16° BTDC / 44° ABDC
Exhaust Open / Close
  • 52° BBDC / 12° ATDC

E36:
Intake Open / Close
  • 16° BTDC / 44° ABDC
Exhaust Open / Close
  • 48° BBDC / 12° ATDC

I don't know offhand.  That spreadsheet has a lot of data, but I'd be careful about trusting one source too much...and there are a lot of typos too.  That always makes me worry.
