Default HELP - Spark plugs for supercharger - colder

Can anybody recommend a spark plug for a aluminum headed gt40x 5.0 with a Vortech V-1 S-trim pushing 9-11 lbs. boost? This is a daily driver. Thanks.

Use motorcraft or autolites 1-2 steps colder. Sorry, can't recommend a part # though.

Motorcraft AWSF22C or Autolite 103 is what I run. I think they are one step colder than stock. I run an A-trim with upgraded pulleys. I might be getting 6 - 8 lbs of boost.

AWSF32C now. Pro, I would like to go 1-2 steps colder. However this is a daily driver and I am thinking that 2 steps may be a bit too much?What do you think.

Also, PM me if you could help with someregistration issuses on the site. My son registered and never recieved his confirmation e-mail and cant acces the site under his user name.When he tries to re-register it tells himhe already has and to follow the directions in the e-mail? WTF
I e-mailed the site and have yet to hear back from anybody.
Thanks
