Methanol Injection and Spark Plug Temperature (a Question)
Okay-
So, I had my spark plug mishap - https://www.cobaltss.net/forums/2-0l-lsj-performance-tech-47/one-these-not-like-other-137196/
Anyway, while I was at the part store buying new plugs I had a question come into my head.
Is the colder plug still a good idea once you start spraying methanol? The methanol is raising the octane of the fuel and fighting detonation so do you still need the step colder plugs?
I bought a set of stock temp plugs AND a set of colder plugs while I was there because I couldn't deside!..lol

Well.. i was hoping for a response along the lines of.. "I've tried stock plugs with the meth injection and i get "x" amount of knock" or "I went back to stock plugs once I got methanol and it didn't knock at all any more!"
Experiences rather than guesses..
Don't get me wrong I do appreciate the input! And I'm running the colder plugs with the "just to be safe" attitude already.. I was just hoping somone had logged some pulls one way or the other..

Eh when you start doing mods with stock plugs that safe zone goes away QUICKLY. So i mean you can prolly more then likely either go to the fact of saying "hey i am gonna try and run it this way until something blows" OR say "Hey i am running good stuff with little to no issues what so ever"

I ran my step one colder coppers to the tune of 25 psi and 21* advance and saw no knock. I then went to 28 psi and was knocking so i pulled timing down to 16*. I would suggest staying with step one coppers for a anything on the m62.

heat/knock/poor flowing intake and head were all part of that eqaution. If the car had still be together and recieved a nice flowing head pissing the carand intake it would have made some serious power on 25 psi 28 is just pissing it off.
