how can i pick up 2 ths. So far my best pass is 7.23@94 with 1.51 60ft.. The da was 890 that day. Wat can i do to get a 6.99 pass? Its a hci 355, I have full boltons, lcas, tq arm, phb, comp. eng, rear shocks. The race weight is 3380. Ive pulled hvac, rear seats, door bars, airbags, tublar k member, and runnin telestar wheels with full slicks. What else can i do fellows

2 tenths in the 1/8th is huge. Assuming the car runs strong and has a decent dyno-tune, you're looking at a significant change, be it cam-related, gearing or whatnot. Looks like you're hooking pretty well too. Are you an A4 or M6? More details the better...

My race weight is exactly 100lbs less than yours, remove the carpet, passenger seat, and interior panels. You have even gone a few steps further than me with the K member and whole hvac system. I dont know what you weigh but Im about 160lbs. You can definitely drop another 100lbs off that thing, and then if you get 1.4 60' like you said I think your there.

More gear/stall.
It will cost you both on the street and in the 1/4 though...you are already doing good but you really can't build one combo that will excel in the 1/4, the 1/8th, and still be a kitten on the street.

Next would be to run a steeper gear such as 4.10-5.13 if your gearing for 1/8th.
By removing the carpet, thats 40 lbs right there for sure. Maybe take out the pass seat and the rears too for more wt loss.

Im really not wantin to increase my gear or stall cause it will make it harder to hook on spray. Plus i do go to the 1/4 alot.. I guess just need pull all weight i can and just spray hell out off it...

i'd put it on a radial. needs more gear and converter, as shown by the 5 tenths you gained (in the 1/8!) on just a 75 hit. The 1.51 short is soft for a car trying to run a 6.99 at your power level. what tires are on there now and what psi are you running in them? Shift extension with the 4L60E will kill you in the 330', that's where the converter comes in. For now...
-Pull bumper supports
-At the track... loosen LCA bolts, jack up front of car to full droop, tighten LCA bolts
-Pull carpet, passenger seat, interior plastics rubber matting on firewall
-Gut dash, !dash support bar
-Run 1/4 tank of gas
-Run !accessory belt. Run a battery charger/push the car through the lanes.

Take out the seats, door panels (18lbs), carpet and sound deadening (40lbs-ish), the plastic panel right under the column (4lbs) front speakers (6lbs), rear speakers (6lbs), bumper supports, leave the battery where it is.
Make sure the car is very low on gas at the track! Bring a 5 gallon can with you and splash as needed.
Just BARELY light the stage bulb. This gives you the maximum amount of momentum before the timing starts.
Launch your car differently and see what happens. Launch from an idle and pay close attention to the 60-ft times. Then try launching it at 3000rpm, 3500rpm, etc, etc. You will find out what your car likes the best.
If your car dead hooks with say.....12lbs of air in the rear tires, try adding 1 lb and see if it still hooks. You have to understand that a saggy rear tire will hook really good, but then you are dragging a partially flat tire down the rest of the track which absorbs power. Have you ever tried to push a car with tires that are low? It takes a lot of power to do so. You want the most amount of air as possible in the rear tires that will still allow it to hook.
