Title: plugs
Post by: Shimy87 on August 10 2014, 10:39:52 PM: If I ever get a actuator back, and can get it to push 25-26 lbs. What plugs at what gap should I run?
Thanks!!

Someone said to use the Autolite AR135. Are those for the aluminum heads?

They are a non projection tip. The AR23 have a projection tip. Have them in the car, seem all right.

Post by: Steve Wood on August 15 2014, 04:41:21 PM: That's the reason I said for E85. Straight methanol is prone to preignition particularly if too much timing is used or too hot a plug. Straight meth also can require a tight plug gap. I was thinking the 135 came with a much tighter gap but I must be confusing it with another one. Sounds like a solution for a problem that does not exist on a driver with alky injection

Post by: Steve Wood on August 15 2014, 06:46:30 PM: At times, on race cars, but not on a driver. Think, when has preignition been a problem on any Street buick that you know of? . Not detonation but preignition? far as that goes, when have you heard about preignition being a problem on any buick race car running gasoline?

Post by: Forzfed on August 15 2014, 07:01:12 PM: This is true, Steve. Maybe I'll have to run crazy amounts of alky! :cheers:

Post by: Steve Wood on August 15 2014, 07:48:10 PM: The only down side I see is that they may foul quicker in street driving. What is the gap?

Post by: Forzfed on August 16 2014, 04:06:10 PM: Funny you say that because I think they are on their way out. I ordered some AR23 last night. Hopefully that makes a difference.

Post by: Forzfed on August 20 2014, 06:23:30 PM: Put the AR23 in today, car runs way better! Won't be using those AR135's anymore, at least I can say I tried them. :P

Post by: Forzfed on August 20 2014, 06:52:28 PM: Thanks, Steve! Are the AR22's one heat range cooler?
Title: Re: plugs
Post by: Steve Wood on August 20 2014, 07:30:29 PM: Yes, they are colder if they make a 22. 23's are close to ac42s
