Stock plugs, stock boost, stock fuel system, took the ground strap off cylinder #4, nicked up the top of piston, and took a chunk of exhaust valve with it. Damn it was hot in there!
Yeah not sure where this is going :smt102. There are so many scenarios of plugs and/or combinations and failures associated from so many different things. Weather it's not enough octane, too much heat, wrong gap, fueling or lack of, blow by, etc... I would hate to have to list all the plugs I have burned up in 25 years of racing. We all know why it happens !!
I would establish the correct cylinder numbering. I have seen more than one occasion where they think it's right but it's not.
Tuning using EGT is certainly the way to go. I would love to have a probe for each cylinder and then you would also know where a problem is if you are chasing an issue.
Our computers are not sophisticated enough to tune individual cylinders. The new Copperhead computers will allow that along with the speed density aftermarket systems. So what do you propose, even if you have EGT sensors in every header tube, and the temps prove that there is a fueling problem to that cylinder.
Well, we would have to tune to the leanest/hottest cylinder in our case. Or we could have injectors tested and use the ones flowing more on the hottest cylinders. It is a lot of work to unlock a bit of horsepower safely. Most are fine leaving that power on the table and run richer than optimum.
It wasn't made clear I guess Matt. He is talking to the 1% that have the ability to control individual cylinders then. Nothing for us stock computer guys to see here.
