    Hi Guys

    I have a Cobra 99 NA and i wonder if can changed the Injectors and MAF (i have injectors and MAF oem) for 30Lb and 90mm MAF Ford racing, or is not recommended this parts for engine NA?
    in my tunner SCT x4 Shows the option Tune for 30Lb injectors and 90mm MAF, this is why my question.


    i hope your feedback


    Best regards

    You could change it, but you'd still need to datalog and possibly tweak the tune. Canned tunes aren't that great.

    But don't bother. You're not going to get any kind of performance. And unless you're running some heavily ported heads and cams I doubt you're anywhere near maxing out the stock parts.

    Search the "NA SVT Recipe" in this forum.
    Folks know I post it almost every other week..It is an approved compiled list of Todd Warren's, AKA NA SVT, suggested effective mods for NA power/torque. The only thing I would modify/add to the list is the improved custom Cams from which Na Svt now sells.

    OH...WTH..

    NASVT Recipe fixed!!!
    NA ~320 RWHP with 99-01 DOHC C-Head 4.6L:
    K&N filter
    OEM Cams
    March damper
    March hydraboost and WP pulleys
    Long tubes
    Hi Flow Cats/Cat Delete mid-pipe
    Tune (canned..more $ for real tuner tune)

    360-370 RWHP:
    NA SVT custom cams properly degreed.
    short runner. (only If running above 7k RPM)
    Tune

    88888888888888888888888888888
    As I think I understand it...FP, 39# injectors and 90mm MAF with retune can be added at this point to extract a bit more from the 4.6 and prep for a stroker or BB stroker build.

    Nice bro, I will consider this recipe step by step, Right now I have the following on my engine:


    JLT filter
    OEM Cams
    OEM injectors
    OEM throttle body (a 65mm works?)
    OEM ignition coils (which is better oem or msd?)
    Light pulleys
    Long tubes 2.5 and X
    Hi Flow Cats/Cat Delete mid-pipe
    Short shifter Pro 5.0
    Soon upgrade IRS full Tilt
    3.73 Gears
    Tune (I have super basic tune SCT X4 When I have everything I will get a custom tune)

    thanks for you feedback

    Regards

    If you want to stay NA, get headers, off road mid-pipe and a dyno tune.

    I were you I'd just save up for an intercooler and used centrifugal supercharger though. Headers sound great but don't have a great bang for the buck when compared to forced induction.

    Stick with OEM coil packs. Aftermarket aren't worth it on these cars.

    I have said this to you before and will continue to...
    If you have a problem with those numbers, take it up with na svt (Todd Warren).

    I'll even start the thread for you.

    BTW:
    Those are corrected SAE power numbers.
    That is the only fair way to compare mods.
