Educate me on reading the plugs on my twin turbo blow thru 496setup. I want to know what why and where
Thanks for the help... I'm going tto get a new set. I do run the lm-2 and datalog airfuel. It is 11.5/7 wot . Never seen 12's. I just worry bout detonation.reading plugs and understanding what is going on both with fuel control and timing is absolutely a great skill to have. I know I've said it many times, but with your setup, you need to buy a wideband O2 sensor/gauge/logger. That engine will melt faster than you could ever react to, get the right stuff to help prevent that from happening.
BTW: I still pull and read plugs when doing street or lake tuning, and I always run a wideband. I still like looking at them, especially for dialing in ignition timing AFTER I've got the AFR exactly where I want it on a WOT pass. And remember the main key to reading plugs is getting a brand new set to put in right before a WOT pass, then shutting it down as quickly as you SAFELY can. Then see what the plugs say about your timing...with a wideband the porcelain ring doesn't matter.
9.5:1 straight 100ll avgas, 8lbs of boost in mandifold, timing at 26 but its lazy and I want to wake it up with some timing .496 CI twin turbo in a jet with intercoolers.
