Ive searched till my eyes feel like they are going to bleed, and i cant count how many sigs. i have read. I am just trying to get an idea of what the maggie is good for in the 1/4. I prefer times with stock heads/cam since that will be what my application is. Boost can vary, for i will run stock at first but more than likely add some psi in the future.
Thanks gentlemen

I was able to run 11.90-95 often with stock 04 engine/cam/heads. I did have 1 7/8 kooks headers, with catted mids, and magnaflow exhaust. Traps were 117-118. This was stock pulley setup for the 04 (0.83 rear setup and 2.9 front).

with an 06, you have a slightly smaller front pulley and some more cubes, and better heads. If you can't run in the 11's then you'll need someone else to drive it LOL.

damn, 11.9 is moving for a headers / stock boost 112 ls1. I hope to be going that quick once mine is installed.

My best numbers are in my sig. Stock long block with stock Maggie boost. I still think it has a tenth or so in it, but I can't launch my car from an idle to get a little higher flash out of the stall converter yet because I need better hooking tires.

nice nice nice. those numbers are right where i wouldl like to be. If i can just touch 11's i will be in "hog heaven."
If an LS1 can do it with stock boost and basic bolt-ons, then i feel confident i can do it.

My mods will be long tubes, cold air intake, cat-back and magnacharger at stock boost...but i am 6-speed. How many of the times listed above were done with a 6-speed?...since apparently manuals are harder to achieve faster times.

The one I posted above was an A4 w/stock stall.

This By State Link might shed some light on your question.
Under Set-Up those having an "11" code mean stock Heads/Cam/Bottom. An s thereafter means Super Charged. There are a few ProChargers and Vortechs, but the majority are Maggies. Thereafter, an *=Headers and an +=Nitrous also.
