Guess my 1/4 mile time

[mk028]

I have not been to the track with my current set up and was wondering what you guys think I may run. I live in Az and would be going to Firebird. I have an 04 cobra with 33k miles. It makes 420 rwhp and 446 rwtq at 15.87 boost. This was done on a mustang dyno that the owners of garuntee me rates my rwhp and rwtq at 20-25% lower then a dyno-jet would. So in therory I would be between 504-525 rwhp and 534-556 rwtq on a dyno-jet. Before I list my mods please understand I am very new to performace cars and upgrades so please excuse any mistakes or lack of information I have. I have the top stage port from Stigmierer (I think they are up to stage 5 but I am not sure), a 90mm big air MAF meter, a 3.1 upper pulley, I know my lower pulley was changed but I do not know the size, a SCT tune, CAI, 2.5 inch bassani with cat back, short throw shifter, upgraded spark plugs, 101 octane fuel (torco), and 315 nitto drag radials to the rears. I have done no wieght reduction. So what do you think my car can do the 1/4 in?:pepper:

Upper 11's to low 12's with a good driver.

I think you will need to add a little more boost to attain over 500 RWHP.

Maybe a 2.93 pulley.

with nitto's on firebird you will be lucky to get traction. fastest i could do there with my nitto's and about 450whp was low 13's. then i went to speedworld the following night and cut mid 12's. i think if you can hook, you will run low 12's to high 11's if you can drive it.

I'm with those guys, low 12's - high 11's with a good driver and traction.

With my set up and all other things being equal (drivers skill, road conditions, ect.) which car do you think does the 1/4 faster between mine and a stock Z06??
