Not sure how much hp I have, but only hp mods I have are headers, exhaust and ls6 intake. Dynoed 300 stock. Probably have 325 or so. Ran 12.44 in pretty good weather. It's all in the 60 ft times.

you are all crazy...
my old formula= 286rwhp 29X (forget) tq.= 12.7's @ 105mph through an unlocked 3500 stall however..
my dsm from a few years ago= 289awhp 305 awtq= 12.40's @ 108mph manual 5 speed
my current car= estimated 320rwhp/320tq= times in sig.
how much hp? depends but 300 should be enough to hit 12's, it's ALL in the launch/shifting if 6 speed. i also back all of my times up and run the time at least 2 times (i ran 12.1 twice before i went home to make sure...) so these are not freak runs.

With a 4th gen F-Body with an A4, anything over 280 to the wheels will get you there assuming you've got a conveter and some sticky tires. Decent gearing (3.42's or lower) will be a plus but not an absolute requirement.

If you want to run 12's close to stock or stock get a auto w/ a stall and sticky tires. If you have a stick it will be more hit or miss well depending on how well you drive. Stick= Skill and practice Auto= **** the bullshit stomp on the gas + your 60 time will be a lot better.

With 307 rwhp I would have ran a few 12.9's but had to let off, because it was during ET drags, I rarely went to just run the car for times. After the LT headers I dyno'd 345ish rwhp(don't have the #'s here) and still ran the same times as I did with 307, Added nittos and 3400 stall and now always run 12's even when the D/A is 4000. My car is heavy due to full boxed SFC's, LCA's, STB, me 300 pounds etc, so I am running at around 3800-3900 pounds.

Stock with MT DR's my 345HP SLP SS M6 was pulling consistent 12.8's and a best of 12.774. I dynoed 327.8HP this summer with it. It's stock unless you count a K&N filter and an Optima battery mods.
