I am in the process of putting my motor back in and bolting on my ATI Pro-Charger D1-SC. Anyone know what gap I should use with the NGK TR6s? I will be running 12lbs of boost on the street with 94 and 14lbs at the track with 110. Other mods listed in profile. Thanks!

I'd suggest you post this in the Forced Induction section. Assuming you have an aftermarket ignition, I'd suggest you gap your plugs at .035". You need a hot spark and smaller gap to prevent the spark from being blown out. I also think you'll want to run a colder plug for 12# of boost; I run 2 heat ranges cooler (Autolite 103s) with 10# of boost.

Yeah, I have an MSD 6AL. I think they said the TR6s would be fine. If I need to go colder then that it should be a problem. Thanks!
