Two stage rev limit?

What's the deal with the 4000 rpm rev limit, when your stopped, clutch in and 1st gear selected?, does this apply to all BOSS engined cars or utes only. Is it possible that it's there to protect the m86 from grenading itself?

its more like to stop the engine flying apart,things get out of control when they are free spinning ,there is a lot of valves in these engines to bend

Re: Two stage rev limit?

I think it's to stop people dialling up 5800rpm and dumping the clutch, most likely some sort of driveline protection strategy.

Re: Two stage rev limit?

I know in my "04" GT there is a rev limit of 3000 rpm when the car is in neutral, to stop u dumping it into drive at 5500 rpm !

Re: Two stage rev limit?

shane3, yours is an auto I take it, by the way you described "dump it into drive", I'm pretty sure that a manual 03 GT-P I test drove o/night did not have this function. Either way, it certainly aids take off (3/4 throttle and slide off the clutch).

Re: Two stage rev limit?

Easy to fix disconnect the clutch sensor on the pedal. Then the thing wont know that you have depressed the clutch.

Re: Two stage rev limit?

Why would you want to be dumping the clutch at these rev's anyway.

Nobody said anything about dumping (there is no point when on 17"/18" steet radials), but rather easing it out. Is there a better way to get these utes off the line than say 40 - 50% throttle, but engine held at 4000, while the throttle effectively modulates open as the load comes on? (begins movement). As for disconnecting the microswitch on the clutch lever, 1) It would likely cause an over-rev as you went to change gears while the cruise control was on (same as knocking it out of gear while cruise is on) and 2) The reason I cranked this thread was to get a general feel as to whether people such as "Rodderz" etc were finding it a handy launch function on the strip. Galaxy xr8, If you are wondering why I dont do this for myself, the ute only has less than 1000 km on it.
