The book from MSD says .050 - .060 with up to 10.5:1 compression. That seemed real big to me on our turbo engine so I called them. They reccomended .040 - .050 for up to about 18lbs of boost.

That said, I'm running 15 - 16 lbs and have my NGK V-power plugs gapped at .045". Seems to run great, have had no problems but haven't had the plugs out yet to look at them.

See my sig for my ignition setup. Hope this helps, at least it's more data.
