| How exactly would the transmission have anything to do with the rev limiter?? Dano why would you be taking the old girl anywhere near the rev limiter?? |
What's the difference between understeer and oversteer? Understeer is when the driver is scared. Oversteer is when the passenger is scared. |

allright, first of all i stated its a manual. secondly, i have an even better engine and gearbox with only 130000kms on it to go in it when this one ****s itself. the engine in it now doesnt even sound like its ready to give up. plus rev limiters are designed to save motors, they take the care to a set amount of SAFE revs, without causing to much harm to the engine. then there are plenty of other factors to take into account, how old is the motor, service history etc.etc. |

| the description makes it sounds like a slipping auto, but you have a manual that i missed. are you sure your clutch is in god working order and your fully releasing it? post some more info or a video because other than a slipping auto i cant think of anything else that would keep the revs on 5500 while trying to accelerate in a higher gear. |

clutch is good, i dont think it has anything to do with running gear, suspecting coilpacks or ignition system. i want to know if its the norm for the rev limiter to sound like this?? |

When you say it pauses- do you mean it hits 5500rpm, stays there for 1/2 a second and then bounces or that it bounces immediately off 5500 and then stays low for 1/2 a second before it revs freely again?
I've said 5500 but I think the six is higher... don't get too hung up on the revs- ít's an example.
The rev limiter is governed by the computer / tune- if there's a drama, that's where the problem would be I'd guess... but it would only be a guess.
Mines only hit the limiter once and it was a loooong time ago but I don't remember thinking anything was wierd about it. If you could upload a video it might make it easier for someone to tell you if it is normal or not. Words are never going to replace seeing it ;) And from what I know, many cars react differently off the limiter- the Toyota Corolla is completely different to the Torago :D
But I guess asking why you want it up that high is a fair question... if it's for burnouts why not get the limiter disabled and keep a bloody good eye on the revs :) |

| so it would do it in neutral as well? by the sounds of things this comes down to the physical dynamics of the motor. the 3.8 is internally heavier which causes more friction(includes lack of overhead cam(s), valve ports and quanity of them, etc)than a japanese 4 cylinder, not to mention theres 2 extra cylinders(being fired in a totally differant sequence)that needs to be forced up and down. you will find it is 'worse' with a v8, but nothing to worry about. still a video would be good to ensure us this is the case. |

| ive had mine on the limiter 4 or 5 times. but i had no traction at the time. mine is a manual series 1 v6. the revs just drop and go back up every second or so, not harshly either, sort of like doing it with ya foot. my greenfoam chip raised the limiter a couple of hundred revs |

| kiwi you hit it on the head, i didnt know how to put it into words, but thats spot on. while im giving it the beans(and i mean THE BEANS) when i hit the rev limiter it sounds as i back off then power on repeatedly. so this is normal then?? |

| if you got a auto it will peak out in gear and then back off (thats driving it manualy) the same as a 5 speed will peak out only so much per gear! |

| yeah dano, its normal. the limiter is a good thing i think, its probly saved me over-revving mine everytime i have hit it. i over-revved an old valiant i had a few years ago. if you want to hear valve bouncing, ask greenfoam if he give you a tune with no limiter :) |
