    Question nos on a 03 cobra

    i have installed the 125 shot nos specific for 03 04 cobras.Only been able to try it at the track one time and it did not work well at all.When i ran the nos the car ran slower than off the nos.It seemed to spit and backfire.I called nos tech and they were nohelp at all.Anyone running nos on a cobra have any experience with this?

    Jdm Wow

    I can not believe JDM has customers from Tennesse. They are expensive but seem to know what there doing.

    It is a wet shot.The system is from nos and is specific for 03-04 cobras.My fuel system is stock.I've done upper & lower pulleys,magnaflow catback,sct tuner by jdm,k&n cold air,sct mass air,accufab throttle body [single blade],larger heat exchanger,sub frame connectors,pro 5.0 shifter & an slp line lock.

    you have all of that and a 125 hot with no BAP...your probably running it lean on the shot...figure your making 460/480rwhp depending on pulley combo's and a 125 shot on that...prob about 575rwhp and 600+rwtq...lol...cmon man...most of these car are pushing the fuel system limits at 500-510rwhp. I have a BAP at 30 percent on a 100 shot on a stock system and am close to macing out the pumps.

    drop the shot to a 50 or gt a BAP. even then (i think) your still pushing it...most people upgrade to 60# injectors when pushing the stock parts that much
