His pinging was an issue because he was running too much compression for the cam (9.7 - 9.8 for the 37):loser: nothing wrong with the cam just the dumbass who did not set the engine up correctly for it:gun:nidan said:I'll be posting a dyno as soon as I've got her broken in . I've only seen 1 on a 31/37 . The guy was running a similar build but on a bagger with fuely. His 37 was pinging and detonating running 10.2 , he switched to the 31 and was much happier, and it is more tolerant to gas grades. This was on the HD Tech forum
Higher compression boosts the bottom end. For high end horsepower, you run larger cams with more duration and overlap...this lowers compression and weakens the bottom end. You use high compression in combination with cams like that to balance things out.berserker said:Do you leave home? I went with lower compression build because lots of places in this country have low octane. Out west 85 is common.
Was explained to me that higher compression produces power at higher RPMs??
