" From: tom jennings <tomj@xxxxxxx> " " Someone with dyno experience ought to know this stuff by the seat of their " pants, me I'm stabbing in the dark... " " When you have a motor dialed in, just how sensitive is it to ignition lead " timing when it's under heavy load? In other words, if you have the timing " dialed in reasonably close, how many degrees away is detonation? How much " power is lost is it's retarded another degree or two or three? " " I know it will vary with combustion chamber and compression and a whole slew " of factors. But for "sort of stock" or stock motors, how touchy is maximum " ignition timing, power-wise? i know that most stock motors don't have nearly enough lead for best power; that's a big reason why recurving kits are popular. " Bottom line is, how close to detonation should one push timing before it's a " waste of time? the nascar guys always used to say they run fastest just before they blow up... ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
