An ngk 8 like ike runs would be equal to the ac41. The ngk#7s of runninghot are like a ac42 and a little more aggressive. As you know I run the ngk #9 because I can without fouling. Plus I don't have intercoolers.

You going out again this yr ike so I can open up a can of woop ass on you

AC R41TS or NGK UR5. They both have a slightly extended tip. If you don't want the extended tip then go with what Ike suggested.

Ive been running the 42's,for 3 years,Precision marine did pretty good bit of dynoing/tuneing with these plugs.no loading up,have good color and half way in the bridge,I use to buy all the racing plugs etc.They are are cheaperalso,I can change them about twice ayear.Ive also run the NGK R5674-8. they would load of on my old carb blower motors at 12psi,it was fat to start with.Hustler motors are efi

I run the 7's in the Chevelle street,drop down to the 8's on NOS,the 9's would load up at the track,

The Camaro are the Champions, are a 57 59's

I use an NGK #R6061-9 plug in my PSI blower motors. It is a plug that PSI recommended for blower applications. Check them out. I also use an MSD #7ML-2 marine box for amplification. Never fouled a plug and they work great with anywhere from 10-16 pounds of boost.

The motors made 1100hp on 92 octane fuel and use the Holley 4150 series 1000+ cfm carbs. If I intend on running it hard, I mix in some 100 LL aviation gas. 7.5 compression ratio and a really mild street roller, solid lifter cam. They have been very dependable.
