stock 9's all the way around but if you go to 14psi or higher I'd run B10evg plugs with a gap of .022
(they require a special socket though)

Just to share my experience, I ran stock 7's and 9's at 19 psi (twins)on pump gas without any problems.(394-407rwhp, depending on the weather.) Running all 9's made my car feel sluggish on the low end. As long as it is tuned right you qwon't have any problems. If you are going to run over 18 psi CONSISTENTLY then I would recommend all 9's or the b10's.

more low end power and "better" dont exactly go hand in hand. The hotter plug promotes more heat which is something a forced inducted rotary car doesnt need any more of.
Just cause someone did it and got away with it doesnt mean its safe.
You can check out Vosko's dyno sheet and see how smooth it is lol

Stephen,
You read this forum too much. What do you mean by promotes?? Hotter plugs dont promote anything and if you were a spark plug 'connaisseur' you would know that it is beneficial to run the HOTTEST' plug you can get away with; as they make the most power throughout the entire powerband. When it comes to forced inductION rotaries, the hotter the better, if you know how to tune it. Trust me that detonation in a rotary is NOT caused by too hot of a plug.

I usually ran 17 psi but I turned it up to 19 when I had to....ie: racing my friend so I can bust his *****!! For the first two years I ran the STOCK injectors (maxed out at 100%) and a basically stock power fc map 5.08. All I did was lower the timing a degree or two in the full boost areas on both the leading and trailing. ASP medium intercooler, rp fuel pump, m2 airbox, RB catback, no cats, crane ignition box(didn't really do much), power fc and thats all I can remember. Stock turbos, stock engine. 12.22@ 122 mph on a 60 degree day. I can run better times but I refuse to put slicks on my car, if I want to know what it will run with slicks it is easy to figure it out mathematically. I did switch to 1300's out of nervousness but all it did was lower my duty cycles.

Yes they do running to hot a plug promotes pre ignition. That is exactly right...the hottest plug you "CANT GET AWAY WITH".......SAFELY
You think running such a hot plug at those boost levels is safe go ahead. My opinion is that is isnt. Sure you can tune around if if you want to mess around and retard the timing every time you turn the boost up. Besides that 75% of the people on this forum are scared to screw with thier tuning anyway so I wouldn't suggest such a thing as running a hot plug then not telling them to turn down the timing....which is what you did. I run high boost everyday and the 10's are extremely smooth and work great.
Also, I dont see what me reading the forum has to do with anything. I'm speaking from personal experience
