[QUOTE="Monkeypants, post: 34567, member: 2708"] Bruce, I'm not sure what modifications Roy made to the Renwick cams. He just mentioned that they were "heavily modified" David, the 12 hp figure is from memory and could be incorrect. The number mentioned was from Terry's 1360 engine running alcohol at 13 to one so likely it is a larger number than if the same cam change was done on a 998 cc motor in a lower state of tune. I believe Peter Volkers uses Terry's MK2 Lightning cams in the bike he used to terrorize the Martials @ the IOM. Terry mentioned that Peter's testing of those cams showed a continued HP increase thru to 6500 RPM whereas engines using regular Lightning cams show max hp and 5500 then drop off as RPM increases from there. His Mk2 lightning cams sound like a good choice for a fast road bike. Hope his health improves, he has certainly improved the health of many Vincent engines! Glen [/QUOTE]
