Well thats hard to say.Are we dealing with a stock setup here?Give the specs on the car and its mods to get a better answer.Most of the time you have to find the cars "SWEET SPOT".</P>


But to answer that with an educated guess i'd have to have all the cars specs and mods.</P>

on a stock motor you dont make power past 4800rpms. you start dropping power at 4950rpm

If its a stocker shift at 4900. But here is the catch, 5.0s are notorious for having tachs that are way off. I bought a AUTOMETER and my stock tach was off 500 rpm from 4500 to 6250(rev-limiter). So if you shift at 5000, it may not really be 5000. It may be 4500 or even worse. I have seen them off as much as 800-900. I am not kidding. I recommend a aftermarket tach if you are going to be drag racing to ensure you get the most out of every shift.</P>

you can pretty much feel when to shift. when you don't accelerate hard enough, shift. <IMG src=smileys/smiley16.gif border="0">

Hi, I own a 1989 Mustang GT with manual trans, the engine is stock. I bought the car with about 160,000 miles on it. Still.. I was able to beat a 2002 Nissan Maxima at the stop light, I was ahead until about 90m/h before the next stop light!! my shift points? 5000rpms. We tried one more time with me shifting at 6000rpms........<img border="0" src=smileys/smiley19.gif border="0">
