Gapping plugs for N20..

**Liveforfunjim** · 09-26-2007, 12:29 PM

So, once i get my kit install completed, how bad would it be to do a few runs with my tr55's gapped at .55? I know N20 needs gaps at like .30-.35

its not worth the wasted time and you always want a good sure spark consider how much more fuel has to be burned and you dont want a fouled plug

your gunna blow the spark out, then get a spark and blow your piston

i've run .050" gaps in other motors. but, don't want to chance a flame out on the bottle. also, go down to TR6 a step colder plug.

WWW.ws6store.com has them for like 10$ if you buy them with msd wires, some kind of package deal or something

I too did TR6's at .035" - no issues to speak of.

How about TR7's plugs at .35 for a 150 shot to be extra safe ... anybody believe it would be beneficial from a safety standpoint or a waste of time chnaging the plugs?

TR6's are safely within the range you need.

**JEB99TA** · 10-07-2007, 09:03 AM

I know they ar well within range, however4, I was just wonderingt if there would be any benefit of going one step colder. Anyone know of a plus to stepping down one range colder? Or, can anyone specify a good reason not to?

i've taken out TR6 a couple of times. i run the NGK BP7EFS equivalent in autolite 104 set at .035"

How did they read after a nitrous run, as compared to the TR6's? Some folks indicate the TR6's get damaged pretty easily and I was wondering if a colder plug would hold up better. If I was gonna' hit it with a 100 hit or lower, I wouldn't worry about. But, I think with a 150 wet hit, it might be the point I should go one step colder.

If you want an all out plug designed for high cylinder applications than run an AutoLite AR93 as I have posted many times before. I don't care for the NGK design myself. Once you look at an AutoLite race plug you will see it is a whole different animal.
AR94's are good to 150 but anything over AR93's for me. If you want added insurance against detonation you could run AR93's with your 100 gapped at .038".
Here is a pic so you can understand that a race plug is a different design.Yes this plug had too much timing that's why the whole ground strap is discolored and it was lean.
