I ran 14.2 with street tires, flowmaster and a CAI. Then i added a 3200 stall and Nitto 555rs and ran 14.1 why should i bother going any further. And psi is not an issue i had it at 16 and 14 and did a long burnout. The best time was 14.1 WTF!!!

 

That is rather dissapointing.

Does the track that you got those numbers from have a high altitude?
If so, I recommend driving to a track that is closer to sea level.
You'll likely find the results pleasing.

If that's not the case - your next mod could be a 100 shot to rocket you into the low 13's.

 

Not sure but its in New Jersey if anyone know let me know. I'm beginning to hate my Z.

 

What was the difference in 60' and mph from the 14.2 pass and the 14.1 pass? Was there a big diff in traction? Did you get the R's way up there before launching???

 

14.2@ 98 2.1 60'
14.1@ 95 2.2 60'

 

Maybe you don't have enough POWER

 

When I first ran i had flowmasters and a CAI. I ran 14.2
Then i added the nittos and a 3200 midwest T ran 14.1
Not enough power I'm still losing the car in second at 16psi

 

Something sounds wrong, I's give the car a full tune up and see what happens.

 

look at your 60's. For every .1 off the 60, you gain about .15 to .2 off the 1/4. You did a faster 60 at first with a slower time. There should be no reason that your 60 is slower with th2 3200 stall and DR's. You need to bring the stall up more. What are you lauching at?? RPM wise? What kind of burnout??

 

What rear end ratio are you running? Sounds like a 2.73.

 

Launched at 2000 and was still spinning through second.
My rear is 3.23.

 

And there you have it..... You aint getting traction, but of course you knew that. You didnt answer the other question though. What kind of burnout are you doing???

 

5-6 second burnout.

 

Dry???? With drag radials, you should go around the water and just nail it a good one. DONT do a water burn. My friends 02 LS1 goes 10.90 on Nitto DR's. He stays clear of the water. He also sold his slicks lol.

 

your mph should be a tad bit higher, even spinning!
when was the last time you gave your car a full tuneup?
IMO i would start with all the basics, plugs,wires,fuel filter,cleaning the air filter, yadd yadda
then go back to the track and see if anything changed
your times and mph are on par with a stock LT1 but definately not one with a stall!
something is not right and i think its more then traction issues! the tracks in Jersey (Atco and E-town) are among the fastest in the country
