Currently I am running NGK BR7EF plugs and the car runs well, it drives around well with out any issues and makes good power at WOT. However as you all know the BR7EF is a standard tip plug. I bought a set of projected tip plugs to try in the motor. Now knowing that the projected tip is more prone to heat and detonation I went a heat range cooler. They are TR8IX's from NGK. Currently my plug has marks up the first 2-3 threads which from what i understand means the heat range is appropriate. And also my timing mark on the ground strap looks good. It looks as though it is running well......but in the search for more power what do you guys think? Anyone have experience with experementing like this or any info they can add? Trying to learn here and experement for more power!!! Every little bit helps at this point lol...

Thanks,

The rule on sparks plugs is colder is safer. I would start with a TR9IX instead of the 8's. If you notice fouling, go to the 8's. It is better to be safe than sorry.
