Quick question...





What happens in a 3rd gen when you hit redline? Is there a buzzer of some sort? Is there a fuel cutoff? Is it even possible to gas it above the redline?



If you can, what would typically happen if you did? What type of problems might the engine develop?



Thanks,

Mike

there is a buzzer, and you will bounce off the revlimiter. I'm using the PowerFC so i do not know if it will do the same with a stock ecu.

Thanks for the reply...



So, pretty much it's not too possible to over-rev the engine?



Can anyone confirm with a stock ECU?



Thanks again guys!

with the stock ecu you will hear a beep once you hit the redline

yeah there is a beep scarred the crap out of me the first time...i have hit it a couple times with my pfc and it still buzzes....stupid slipping clutch

Kremlar 07-31-2003 09:20 PM

Is there also a rev limiter with the stock ECU?



If not, what would happen if you over-rev?



I know this is a stupid question, but please humor me...

well i would imagine if you over reved it would break stuff just like any other engine....i mean the term over rev in itself seems like a bad term. so moral of the story dont over rev

apexkw 07-31-2003 10:43 PM

you might get lucky and not break anything for a couple times but eventually **** will break

Kremlar 07-31-2003 10:58 PM

Just came up in conversation the other day with someone...



Thanks!



And if anyone knows if stock has a rev-limiter please let me know...



Thanks!

Yes, I'm pretty sure the stock ECU has a rev limiter!!!
