    Rag Top NHRA question?

    A friend of mine with a Conv Vette that runs 12.8 - 13.0's was approached at the track Sunday that the new NHRA rules require any Conv running 13.99 or below requires a roll bar or cage. What is up with that? Is this new? Does this mean that all Conv Cobra's cannot race without a bar or cage?

    LM1 AF Readings

    I have an LM1 AF meter. I ran it today using the new tailpipe adapter. I have the stock cat mid section and MagnaFlow Cat back. I know that you should take AF readings pre-cat, but have read and been told that you can use after cat readings but it will read about .5 lean. (i.e. a reading...

    What is the cheapest way to get a set of wheels for slicks? Can you get a 15" steel wheel to fit the Cobra as a direct bolt on? If so what are the specs? If not what is the cheapest aluminum 16 that will fit? I donlt really care what they look like as they are for the track only. I...

    04 Throttle Sticking Wide Open Problem

    After reading about a few 04's sticking the throttle I am pissed as mine stuck today in 3rd at the track. The pedal bracket gets stuck behind the carpet. I trimmed it about 1" away and it was fine. Ford better have an emergency reacll before someone gets killed.

    O2 #'s vs AF #'s

    From what I read the approx O2 sensor volatge for 12.0 AF is 1.0. Is that true? My O2 reading is .92 at 6000 rpm in 4th. Is that too lean?

    Tune Specs

    What should the ballpark optimum full throttle max advance be with my mods? What would the O2 sensor readings be at full throttle for ballpark AF readings? I assume that the O2's readings can be converted to approx. AF readings? I can read the above parameters with my Predator.

    Steeda vs Magnaflow

    I am considering a Steeda or a Magnaflow Cat Back for my 04 Cobra. Any opinions? I do not want it to sound like a kids GT and to get dirty looks in traffic (unless I am doing something stupid). I do not want a drone at cruise. Deep clean sound yes, crackle pop, back off, no

    2.93 vs 2.8

    I have a 2.93 with the so called non slip slots on my 04 and am not happy with the belt dust. I am going to add the Steeda Auxilary pulley and a std groove 2.93 or 2.8 pulley. What is your real world opinion on the pulley sizes? I will race the car occasionally so ET is important. I have the...

    Steeda Tri Ax in 04

    I installed a Steeda Tri Ax in my 04 and although it shifts great it is much noisier than I remember any shifter change I have done before. I have exerienced the typical (at least what I call it) on other cars when removing the stock rubber mounted lever, etc., but now I hear so much trans...

    BBK 65mm 03 Cobra Port Matching

    I have a 65mm BBK TB for my 04 Cobra and would like to see how some users have port matched the intake to it. It looks like you need to radically port the intake pipe to match it, not a simple dremel type clean up.
