Are most higher compression guys running these plugs?

Any running DR10EA?

Stock is DR8EA.

My understanding is the DR9EA is a cooler plug so will have less of a tendancy to cause pre-detonation?

Thanks.

 

I run the 9's but I want to run the 10s.

 

I'm running the DR9EA on a 11:1 piston. Never tried anything else, so I can't speak to the gains or losses.

im runnin the iridium stockers, whats the benifts of 9's over 8's?

 

See above as to why you may want to run the cooler plug.

Compression creates heat. . . pre-detonation.

 

And thus if you are borderline on the compression octane idea, say runnin 11.5-1 on 93 octane, could you use a DR9EA or a DR10EA and get away with it? Or would it at least help reduce the chances of a boom?

 

I run the 9's and my heat is exactly at the turn on the ground strap[img]i/expressions/face-icon-small-happy.gif[/img] can't get any better than that

 

I run 9's on the bottle. With the 8's I would melt a plug (only twice though). I could back the jetting down on the bottle and be fine, but what fun is that....lol

Oh and just fyi I have been running 28 n20 and 31 fuel, which is around a 30 shot on the stock piston. Everything has been good so far. Got about 20 lbs through it. [img]i/expressions/face-icon-small-happy.gif[/img]
