Spark plugs for forced induction

[2002 v6 camaro uncharged]

What are the best and most reasonably priced spark plugs for my powerdyne supercharged camaro. Also, what is the reasoning for regapping the plugs to .035 like the RKSport instructions tell you to do. I this necessary, does doing this reduce spark knock or is there another reason.
Thanks in advance for the info.

if you would look 2 posts down (thread called: What NGK spark plugs for Turbo TR6?) you could get your answer.

Thanks, sorry that I didn't take the time to search but I am trying to this in between people walking by my cubical at work.
Thanks

You would definately want a cold range for a force induction. It decreases the likeliness of detonation and knock.

NGK TR6 is the cheapest and maybe the best one and you don't have to worry about regapping them like the instruction say.

The ngk TR6 are TWO heat ranges colder than our stock plugs. this reduces the chance of predetonation.

The smaller gap (.035 suggested) as opposed to (.060) is to reduce the chance that the spark will be blown out due to the high compression in the cylinders. (at 5pis boost your piston cylinder is now running with 14.4 compression ratio vs. 9.4 compression ratis (stock)

This much higher compression ratio is why you need to run high octane (premium) fuel. It is also why the kit comes with a timing retard system. The higher compression in the cylinders means timing must either be retarded or super high octane gas must be used. High octane gas burns 'slower' than lower octane gas. it can yield more emissions if it is used in an improperly tuned vehicle as opposed to using regular gas in a car tuned for regular.

I don't use any timing retard on my 6psi set up. i do use premium fuel and the ngk tr6 gapped to .035. I did have to re gap them to get them down to .035. If you can get away with longer gap then that is fine...but if you car starts to misfire the computer will start pulling timing.

Thanks guys, Maybe that is why car bogs down under boost soemtimes because my miss fires are pulling timming.

I ordered the ngk tr6's yesterday and recieved them today and i Checked the gap on them and they were pre gapped at .032. Is this good enough or do they need to be gapped to .035. Can who ever responds give me a reason for either way just for my knowledge. Thanks alot

That's exactly what I have. Mine was so poorly shipped from Tbyrne that the gap on a couple of them was messed up a little bit and have to regap them to .032.

...correction more like 10.0 and IMO if you are running low boost, 0.032 is not necessary...

[2002 v6 camaro uncharged]

Is .032 good if I am running 9psi and if not what would having the smaller gap do?

[Mighty Thor]

Non-intercooled... It is necessary.

Would you use the same plug setup if you had a water injection intercooler?
