MSD 6 and 100 shot DP... 0.35" plug gap??
 

setup is a b18b with 100shot direct port, I know the standard plugs reccomended for 100hp+ is one step colder so that would be 7's(BKR7ES-11), but I'm kinda confused on what my gap should be?

I found this on another site for turbo cars running 7s and MSD, but would this apply to my situation as well?? I'm guessing I should go for around 0.34-.035"??? oh and the MSD will pull 3 or 4 degrees when the nitrous hits.

"MSD + NA = 0.50 gap
MSD + boost under 8 psi = stock gap
MSD + boost over 8 psi = 0.34 max"

I've read to run the biggest gap you can without missfiring or bogging. Start at like .04 and see if you get any missfire or bogging on top end and then work you way down until it stops. Mabye go a little smaller just incase.

have you noticed yet that everyone refers to spark plug gap in mm's except for you ;), but yeah, just leave it at like .35 and don't go smaller unless you have a problem blowing the spark out, then try .30, and so on..

no, everyone does it in inches, but you guys are forgetting a zero, it's .03" not .3"

if it was millimeters it would be around 1mm.

Look at the stock gap for a zc in millimeters.

Everybody always says .(whatever) but its .0(whatever)

well, my spark plug gapper has two units of measurement on it, one is bigger, and the other is smaller and refers to gap size the way i'm referring to, and any time i buy plugs or see anyone referring to plugs, it is always '.35' or whatever the gap is with no zero, oh well, as long as we all know what the other is talking about ;)

cool makes sense fellas, I'll go with .35 and go from there thanks :)
