| 1992 FLHS Vince Barlow from Alberta, Canada looks like a typical touring rider. Laid back, relaxed, in no big hurry to get anyplace, except maybe the next bar. Vince has a little secret hiding between his legs. |
|
| Vince has spent a lot of time and effort to put together a good performance package for his FLH. Don't stop reading once you start. You may be surprised at the path Vince took to get to his final engine combination. |

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. 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. Updates from Vince on his tuning: The May dyno run used the stock CV carb with a Yost kit (45 slow, 175 main, needle middle position), and the 3030 V Thunder cam. It has 8 degrees later intake closing (44) vs. the EV27 (36) and a LSA of 104 vs. 101. I'm running the same Dyna 2000 but now curve 3 (32 degrees) and in dual fire both runs. Cranking pressure dropped from 210 to 190 - and absolutely no detonation. I also replaced my lifters with Jims, which I think accounts for the lack of top end on the Fall runs. So she pulls the same 90 ft-lbs. (now at 3800 instead of 3600rpm) but the top end works and she pulls 78 hp. As we speak I'm running my SuperTrapp slip-ons with 12 discs left and 18 right both with closed end caps and she runs real strong, but haven't got to the dyno yet to see if this out performs the Bubs. I'll let you know. And Vince continues to tune and improve his performance. |
