looking for a few more tenths...
looking for a few more tenths... im currently stuck at about 12.9@105ish with a 1.9 60ft drag radials. my mods are lid, ported maf, ported TB, 1 3/4 LTs, 3in catted y, 4in flowmaster merge and dynomax bullet, 3200 stall, bmr torque arm, pan hard rod and LCAs, and hotchis lowering springs. i was thinking about undoing the front sway bar and running shorter belt for just the water pump, and alturnator. does anybody know if doing this will get me a tenth or 2? and if so what size belt do i need?
weight mods, I have gone 12.56@111 with A4, stock stall, stock cam, just headers and P&P TB. Oh yeah LS1 Intake with plug in top. lol......My car weighs 2980 lbs......So weight mods will make you alot faster. Did this on 215-60-16 street tires (bald). 1.9 60ft

There are a millions threads but the tip of the ice burg for weight:
Spare tire
Sway bar
passenger seat
rear seat
light weight battery
Again millions of little things but those right there are free and simple except the battery.
You can run a 50 shot of nitrous. Should drop .3-.5 and have you a mid 12 car without anything else.
Rule of thumb is 100 lbs is .1 in the 1/4, but, in reality it seems to be minimal gains for 100 lbs. 200-300 lbs usually you will start to see a consistent et. drop in the .15-.2 range. Every car is different but I haven't seen anyone pull 100 lbs and have a consistently .1 quicker car.

what size tire you can try a shorter tire, i removed the front swaybar and brackets, A.I.R., includung pump, cruise control ecu and cable(didn't work), front bumper support, trans tunnel brace, spare in jack, my 01 ss m6 weights 3300w/o me been 12.49@115 street tires and similar mods.

There is not really many weight mods to do with out messing things up, i mean you can do the really light weight battery like i did(saved 30lbs over my optima),
take out the back seats and seat belts(mine weighed 31.8 lbs).
Front swaybar will def take off weight, not sure how much it weighs.
light weight wheels are good but very expensive.
take the spare tire and stuff out of course.
Run less fuel in the tank at the track!!!
race seats.
lightweight carpet
Drag brakes
you can take the exhaust completely off like i did lol except for headers of course, mine had to weigh around 75 to 100 lbs because of what it weighed at the scales.

i am running a 275-50-17 drag radial in the rear of course.... i already removed the spare tire and jack. and i usually keep less than a half tank when i race. i dont think im bogging down or really spinning what i launch maybe ill have to do a big nasty burn out??? but i do know my damn y-pipe bangs most of the way down the track. thanks for some of the tips i may try and take out the rear seat and passenger seat if i can convince my wife not to come or take her own vehical how hard is it to remove the seats?
