   i have a saxo vtr 1998, just curious to what it can actually rev up to and does it have a rev limiter?,most i revved up to was 5500 rpm i think.

   Do you not have a rev gauge?

   yeah but what im saying is most ive revved upto is 5500 rpm,sounds like its really going for it that high and i havent been higher,so im asking does it go further and if it does,does it go further think it has 7000 rpm on the gauge, but im assuming it wont go that high as its standard.

   it will go that high but it's alot of wear to the engine

   A normal vtr won't, the engine management limits it to 6250. Only Peugeot 8vs go to higher but they are different units with different management. Physically it could rev that high but expect problems if you don't update the valve train properly. No point revving high on a standard vtr all the power is lower down that near the limiter

   Maximum power is around 5800 rpm in the VTR - yes it will rev a little higher (before reaching the limiter) but there's little point. You should be changing gear at the peak power point to maximise performance.

   I'd disagree with that.. You want to be changing gear at the point at which the revs you will be at in the next gear will produce more power/torque (whatever you are after) than you are at in the current gear, at the current revs. The power doesn't drop straight down to 0 after max.
   
   Changing at the max power point is rarely the quickest as you will often drop to a lower power point than you would by carrying on for a few hundred revs past max power and then changing up. All depends on your power/torque curves as to the ideal change up point.

   This is true! Say you change gear at peak torque/power, when you change gear you may be further off peak power in the next gear, so by revving it a big higher in one gear, ok you may lose a few BHP by revving higher but when you change into the next gear, you may gain more BHP than you lost in the last gear. If that makes sense to anyone? Haha

    All I have to say to that is you clearly need more power
    
    
    
    
    
    
    
    Ps - I agree
