03 factory rev limiter>fuel or spark cut off?

[MacMan]

Anyone know if the 03 Cobras still limit the revs but cutting off fuel?

I've heard that cutting fuel from SC'd cars is VERY bad, thus I have MSD on my 98 to cut the spark instead. However, if Ford is doing it...

I believe it is 6,500 rpms

Also used to aid brakes for the traction control.
They do it this way because a rich mixture is bad for emissions.

F%$K emissions!

So anyone know if cutting the fuel is really an issue? Or is MSD just blowing smoke up my arse?

Seems like if it was an issue on supercharged engines, a lot of 03's would have already exploded upon hitting the rev limiter.

According to the Ford SVT spec sheet it cuts off fuel @ 6,500 rpms.

Yeah, why would Ford shoot itself in the foot. I have found that short shifting at 6200 yields accleration just as good as redline anyway.

Same here...

with autocrossing though, I tend to hit the rev limiter every now and then (rather then shifting into another gear at the last second of a straight). So the rev limiter issue is a pretty big one for me. But I'd looooove to get rid of the MSD and go with a Jacobs instead (MSD tach adaptors=sh*t). The only reason I still have the MSD is because of the spark based rev limiter. THe Jacobs system doesn't have a rev limiter.
