RPM question

[94silverbullitt]

my mustang has a few mods to it BBK 70MM throttle body, cold air, and underdrive pulleys, graniteli MAF, 4:10 gears. My car red lines at 4500rpm, is this normal or do i have a problem, and will a MSD ignition box fix the problem?

thanks for the help

What do you mean red lines at 4500? do you men it just stops? or wont go anyfurther than that or what? i'm confused mine redlines after 5 on the rpm guage :dunno:

the car just wont go any further it kinda boggs out, and mine is an auto, i just thought they should rev up higher than that

If everything is working properly like your plugs/wires and all the other tune up parts, sounds like your car is just choking because you need headers and more mods..... sounds kinda odd with 4.10s though.

Does it happen in all gears, maybe your in your overdrive gear when it does it.

does it in 1st and 2nd gear, i starts is at about 4,400rpm i thought that my be stock, wont a MSD ignition fix that problem?

Is the car breaking up or falling on its face? Throwing aftermarket parts at a car will NOT fix something that is broke.

the car is breaking up and slowing down but no just like shuting completely off and falling on its face but it starts to break up. i dont know if that is stock or what you said it may be broke
