LONG Tue, 20 January 2004 04:38 this is really weird Ed..... hmm, if the mixtures are spot on/rich, and you wind back total timing 10 deg, will the hole/pinging still happen?? if so, i'd have to agree that it could be pre-ignition rather than pinging.. around 3500-4000 is where you would expect peak torque to occur?? if so, you might just have too high a volumetric efficiency for the compression you have...so too much mixture is getting in, and then the rise in temp during compression is too much... if you back off timing and it still happens then.... try using small throttle, and see what happens. keep using larger throttle openings until the problem occurs. if it starts at say 70% or whatever of full throttle, then you might just be getting too much air in there water injection is one way to fix it (if timing doesn't work) but the more common way to do it is to cover the problem with fuel and ignore it heh heh... hmm, tried setting plug gaps smaller? say 0.9 or 1.0? i have had issues with to high a plug gap, even tho i get massive sparks from the HEI (like 30mm). i found that at cetain rpm (which changed with the timing) the spark was just being blown out.... anyhoo, a few things to try.. back off timing see if it has any effect, back off throttle opening to the point where it stops happening decrease plug gaps and see if it makes a difference also maybe try AFM to make it richer across the board to see if you can drwon out the prob with fuel at the rpm range? oh, and you're plugs are now 7's?? good luck Cya, Stewart [Report message to a moderator]
