Power mods: EWP, Lid, and a TB if you can find one used for under 150-175, otherwise save the money to put elsewhere.

Drop as much weight everywhere you can. be creative

If you can pickup 15-17hp from the lid/EWP and lose 75-85lbs you should be able to hit 10.90's

Aluminum radiator won't save ANY weight. The stock radiator is very light. A single aftermarket fan can save a few lbs.

If you live somewhere like I do where we run all year long making a pass in the winter time will help tremendously. I usually run a couple tenths faster. Couple that along with the mods listed above expect for maybe the throttle body, you will have a 10sec slip. Good luck.

The car has the electric water pump mod on it just need to find more creative weight savings. Im going to leave the wipers and electric windows in it but will look at everything else (free) possible.

suspension, weight, gear, trans and stall?
I guess the main things were combo matching and weight, car needs more stall without a doubt though.

Are you running a steel driveshaft? My car picked up a solid tenth when going from the stock LT1 shaft to a stock lS1 aluminum shaft and it only cost $100. This car is very believeable b/c I ran 11.20@120.8mph on motor about 5yrs back with a 350"Lt1 setup to run n2o. My car even had factory M6 3.42's in the 10bolt when I ran those times. My friend Frank 95z also ran 11 teens on a stock shortblock LT1 and a baby 224 cam so it's possible but not easy. I think 10's will take better 60' and some awesome weather but possible. Later

the lid is worth 2 tenths according to what everyone on here that has done it is saying. the EWP will probably do it. all your gains are up top with it

in the 1/8 you may....OR you may pick up some due to weight loss, cooler temps compared to normal underhood, and not enough time spent at speed for aero to play a big role.

Very good point.....the law of deminishing returns. Definately applies in racing.

Empire?

We had some pretty good air last night considering how humid it has been. Post the slip or the details if you would! Cars running good!

thanks for the help guys! heres a couple of timeslips,

60' 1.522 1/8 7.043 95.66 1/4 11.123 121.13
60' 1.511 1/8 7.066 95.40 1/4 11.158 120.88

weighed the car last night at nyirp and it was 2900 without me and 3110 w/me. There is no metal cut outta the car brackets and all are intact so there is room to go lower.

The car ran the 11.12 with my friend driving (he weighs 170) and the 11.15 with me (210)

Do you have the 330' and 1000' times? You have obvious room in the sixty foot times. You are getting to the point where weight savings will only show small gains. Keep in mind that ice, tire pressure, and lubricants can be your friends!
