Just want to know.....has anybody tried using large duration numbers for induction on a .12 engine..like 220, 230, 240. If so did you like the results?
On my engine ( PS12) induction is 230 degree, open at 25 ABDC and close at 75 ATDC, but it will not work on conventional design due to the great crancase volume. The best opening so far I found for MR12 is 215-218 degree, but the is great chace that shaft will simply broken-not a realy good materials are used for mas production engines. I heard a lot of modfyers are faced this problem.
