about what would the 0-60 and 1/4 mile times be for a cobra with these mods
2.8 pulley
sct tuner
exhaust
intercooler
K&N air intake
about 450 RWHP

Thats good for a low 12 maybe high 11's with a good 60ft time.

its pretty much what he said depending on where you live, if you live in northern mass like me. then you could go a bit faster in the fall i am sure. i have seen some cobras with those mods and some good tires get into the low 11's easy....and obviously the good driver mod helps too!

How much torque are you putting out? I saw a guy at the track with the same mods run a 12.3 but he said he's run quicker.

and drag radials or slicks always are good too. With those mods you would also want to build up the IRS a little so you don't brake your rear end.

Good traction and that is worth all of a 11 sec ET.

Without it, plan on running mid 12's until you can hook up.

Mr_Cobra

Sorry i have been out for a couple days...thanks for the info. Torque is at about 470 last time on the dyno it was 463 torque and 440 HP and the only thing i have added since then was the K&N air intake. i do need better tires and what tires would be good to get and what can i do to strenghten the IRS? this car is not an everyday driver car but i do drive it a good bit so i would want something that is still somewhat road friendly. i dont think i will be putting much more HP into it for a little bit but i do notice if i romp on it i get wheel hop.....i know its bad and i pull off as soon as that starts but i want to know what i can do to prevent that from happening. thakns for the input

Get some Nitto 555r drag radials and an IRS brace.

Definately go with the brace. I just got one for my car. Didnt install it yet but hopefully will get it soon. You can get the bushings as well and lowering springs. That will help a whole lot. And if you want to get crazy level 5 halfshafts. Getting kinda pricey though.

my buddy has a 2.2kb on his car and it went 11.3 on a stock irs... 6k launch on slicks... as long as it doesnt hop your not going to have problems
