Went to the track tonight. Weather wasn't the greatest. The DA was 3150 at 6pm and was 2600 at 9pm when I made the 12.80 pass.

60ft: 1.81
1/8: 8:21 at 84.46
1/4: 12.80 at 107.66

I guess Im in the 12 second club now. Looking for Mid 12s in better DA.

 

It scares me how similar our cars are ... 2002 black z28 headers ory just bought a lid and I have a 2800 stall and 3.42 gears and udp

 

Thats right on par with my N/A times as well.. I have just about the same mods except i still have 3.23 gears....

 

Did you notice any real gains with the underdrive?

 

I don't think you can notice a SOTP gain from udp but it does free up some decent power if your looking for easy hp

 

I have not installed it yet along with the gears hoping to see low 13's or maybe even 12.9 fingers crossed

 

Oh you should def see a 12.9 for sure maybe better.

 

Just got back from the track and my times are 100% identical to yours. What was the temp. when you ran these times?

 

I installed the slp lid and asp udp it feels a lot more peppy and the mid range seems like it has picked up some useable torque!! Next are gears and a tune maybe ill be making a thread in this section

 

My buddy had LT's,Circle D 3K-3200 stall,Lid,Free mods,323s,DR's,Frost tune he went 7.90@90mph with a 1.7x 60ft. The weather must be hurting you with the DA that high..

 

The temp was around 73 degrees. Humity was 94%. Da was around 2600 for my best and last pass. What are your mods?

 

I think I can get my 60' down into the 1.7s and in better weather I believe the car has mid 12s in it. I know there are other people that have pulled it off.

 

My mods are full bolt-ons but no headers/ypipe w/ 2500 stall. I ran in 81 deg. weather with 94% humidity.
