What spark plug to use at 10 lbs of boost
You won't be able to get anything cooler than a -7 at your local auto parts store. Order the -8's offline. Gap at .028-.030, tighten it up if it blows out on high boost.
gonna run it on 25lbs all the time on pump gas and meth....does this change anything...car wont be driven much cuz i travel 10 months a year for work... but still wanna drive on street as well
I think you're dreaming if you think 25lbs on a 408 is safe on pump gas + meth regardless of what plug you're running. Let alone thinking a pt88 will even make 25lbs on a 408, if it were possible back pressure would be 3:1 and you'd have so many detonation : head lifting issues it's not even funny.

When he said PT88 it didn't even really click he was wanting to do this on a 408 even though he stated it. I was thinking more about the plug selection on 25psi and on him needing to use race gas if he planned on 25psi. I would use the 8's for sure, but your going to need a S588 to make 25psi on a 408.
What issues do u think ill have with the pt88 and y?? Just tryin to get a better understanding on this... And i thought that by adding meth it would compensate for runnin pump gas instead of race gas??
