initial engine setup was Edlebrock Performer heads, Wiseco 10:1 pistons, Dyna 2000
ignition set at curve 3 (32 BTDC), with an Andrews EV-27 cam and S&S Super E (29.5
slow, 68 main), and BUB Dresser slip ons.
The results from these modifications were 90 FT Ibs torque at 3600, and 70 HP at 4800 with
strong detonation tendencies.
From your WEB site I decided to forego the Super E and "just" try my stock CV
with a Yost kit, needle middle position, slow 45 and 175 main. It was then much improved
with some detonation, but much better. So from your excellent cam listing and technical
explanations, particularly the Lobe Separation Angle discussion, I chose a V Thunder 3030,
similar to the EV-27, but with a later intake closing and wider LSA. New Jims lifters were
added since the bike has 100k miles on it.
With the new engine combination there is absolutely no detonation, the same 90 ft. lbs.
but at 3800 now, and 78 HP at 5800. That's with the BUB pipes. I'm currently experimenting
with my old SuperTrapp Dresser slip ons and think there is some potential for improvement,
but only a dyno will tell.
