Ive noticed that 99+ guages show 5800rpm as redline while the 96-98 had 6000rpm redline, Well my question is which one is it, because I dont want to do damage to the engine if 6000rpm is already into the red.
Thats odd, I would figure that the 98 NPI cars would have an even lower RPM due to it making even less HP up there. 05s also have a 6K redline...heck even the 01 bullitt stangs have a 6K redline. I shift at 5800RPMs right now, after cams if all goes will ill up it to 6250. From what I hear the limiter is the same on all the cars 6250 and ford suppodely gets a test car and bounces it off the limiter for 30 mins straight. If it doesnt let go then it passes. If the limiter is set at the same RPM I wouldnt worry about it, the internals of all the motors are about the same strenght, the 05 being the weakest. Its funny, its the 05 guys that are shoving S/Cs on their cars and dynoing them at 450RWHP and 6700RPM and no breakage. I dont think our motors will last 6700RPM on a dyno for 1 pull LOL, but i guess they will.
i've hit my rev limiter at least 20 times and i have the rev limiter raised via a superchips max microtuner. i wouldnt worry about it, my car still runs like a scalded dog. i defiantely need to in vest in a tach w/ a shift light, but damn it just pulls so hard until i hit the limiter, lol.
Why are the 05s internals weaker? Its not that I dont believe you but what makes you say that. Especially if they are handlign 450whp, a 99-04 certainly cant handle 450whp for very long, at least not the majority of them cant.
I believe they are the same style internas as the 99-04 GT. Correct me if I am wrong but anyway.
If I remember correctly the rev limiter on mine was 6050 stock.. I bumped it up to 6300 just to get it out of the way but rarely exceed the 5800 redline.
