12.9@90 it's going to blow up about the 1000' mark.

Your time will definatly depend on the traction. However if it hooks like a MF, I would venture to say at least low 13'3, if not high 12's.

I've had ones that I put together for people range from 12.8 totally stock (including exhaust) on normal 245/50's to 11.7's with headers, 3.73 gears & 3000 stall converter on drag radials.

Get a tune & some injectors before you make junk out of it.

Hell, I ran 13.3's with just bolt ons on street tires through full factory exhaust. I also ran 12.85 on street tires with just a hotcam and no stall. I would imagine he's making more hp and tq than I was with a hotcam. I would say a mid 12 if you hook up.

He's running 3 less lbs of boost. So, a mid 12 sounds reasonable.

As stated, theres not a ton of boost here. Plus, it doesn't sound as though there is much, if any, suspension work done to the car. I stand by my first response of low 13's to 12's depending on traction.

i would say mid 12's sounds reasonable with some decent tires

Re: blown + intercooled LT1 1/4 time

I am in the process of finishing up, and sending the PCM out, so i definately will not be running this w/o a tune. The injectors will be fine, as long as Im at 8 pounds of boost. Thousands of people have used 24lb injectors, with the FMU and not had a problem (remaining @ 8 pounds of boost, no more). However, with the free flowing exhaust I will most likely only see around 7 pounds of boost. I will do some sub frame connectors and some stuff to stiffen it up, and some slicks will be ordered as well. I want the M/T ET street tires, anyone have any preference for wheels? With slicks, all of the mods, and a tune, I am firm that I will see mid to low 12s.
