The trick to getting a full weight car into the 12's once you have all the bolts on is this:
lightweight wheels and tires with slicks/skinnies (this is worth .2-.3 by itself) and most don't do it.
and lots of practice.
Bypassing the PS/AC for just the track is worth a little too.
The weight loss helps but I have no doubt my former engine could run a 12.99 at close to full weight. It would just have required a little more effort (namely 4.10-4.30 gears). I ran a 12.78 in bad air (over 1000DA).
As far as my interior, it is pretty sparse.
Drivers seat only and its a lightweight seat
full dash and components underneath including AC/ETC.
no passenger seat or rear seat.
full carpet and sound deadener except for the trunk carpeting.
still have the factory radio but only have two speakers.
Door panels are still complete and intact.
Getting weight off the car isn't that hard, just expensive
x pipe / no cats
That right there is an easy 300-350 pounds pounds.
If your desperate..... Take off the front (didn't do) and rear crash bumpers (did this) and the front swaybar (did this)
I daily drive this car by the way
I just have a truck to use as well when I need to carry lots of people.
You need more stall....
