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.

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??
