If you’re at 400HP with your single turbo set up I'd stick with 9s all around. That's what I was running on the stock twins at ~350wheel (~400HP) along with HKS twin power. I didn't have any issues with that combination, and I'll be running the same set-up with the 62-1 unless I have some issues. I haven't read anything definitive recommending otherwise at that power level.

I run a jacobs rotary pro pak with an FC leading coil, and typically run 9s for anything under about 1 bar. For higher boost, I run NGK or Greddy Race plugs in 10.5 or 11 in the leading holes.

With a good tune you can run some colder plugs, and be alot safer IMHO. I run 11.5s, but I am going to give the Denso 11 range Iridiums a shot. I am @ 500rw@22psi. Brian, what is the downside of the race plugs besides cost? I am seriously hoping to get more miles out of the Iridiums, but we shall see.

What is the least expensive plug that can be street driven? Where do you get them?
