How Fast with This New Setup?

[MY91GT]

I just got an RPM intake and a 75mm TB(i know it may be too big-we'll see) and a tremec with a 3.35 1st compared to my Z which had a 2.95 1st. My best time before with a 65 TB and a TFS Track Heat was a 12.9 @ 107.5 with a 1.98 60' without powershifting or slicks. What do you guys think? Low 12's with slicks? Or, do you suggest anything that I should change? How bout a home-made ram air(homedepot)?
