Who runs autolite 3922 plugs, and what's your combination??

Who runs 3922 plugs, and how much compression are you pushing? I want to shoot the gas on my car, about 200 shot, and I've been told to use this plug. I have around 10.5 - 11.0 to 1 compression. I've sprayed up to a 150 no problems with a 3923 plug. Now I want to step it up some. Thanks for any help.

I've sprayed a 200 shot on my 10.8:1 347 using 3923's....I can't seem to find 3922's anywhere anymore. I think you would be fine to still use the 3923's.

Well I've ran the 3924's on the motor. Used 3923's for up to a 150 shot of nitrous. What would be my next step for a colder plug if I want to spray a 200 shot? Like Jeff said, the 22's are hard to find and not very common. Can you actually run too cold of a plug?? I tried the AR3934 plugs once, and the car just didn't respond the way I had intended!! Thanks

yes although not sure how you can tell

i thought i heard someone say that you should run the coldest you can 'till you start having driveability issues at which point you have gone too cold and need to go back up one

any know if this method works...???
