Does someone know how to unblock the RPM (blocked at 3500RPM) on the 2nd Gen Intrepid's ?
Yes, it is a safety feature, but not for the reason you mentioned. High revving a motor with no load on it is very bad for internals...and just plain stupid.lvdodgeonstock said:i think he is talking about reviing the motor in p or n lol thats a safdety reason if it goes past that u could and might just break the motor mounts
LOL! True...but who cares about destroying a Honduh?! :biggrin:alarkyokie said:"bUt hOndAs caN dO thAt!!"...
When people say that, are they meaning that the motor could overspeed (say go to 7000+ rpm and self-destruct), or are they saying that a motor rev'ing to, say, 6000 rpm with a load on it and briefly staying there will not damage it whereas rev'ing to 6000 rpm and briefly staying there with no load on it will damage it?In2Deep said:...High revving a motor with no load on it is very bad for internals...

My friend owns a 2004 Civic and it cannot rev above 2500 rpms standing still with the brakes applied in drive, and around 3-4k in park/neutral.
It's proablay a matter of a concern for over-rev'ing the engine because it has no load (to keep the revs down to a reasonable level). People take that genuine concern - they hear that rev'ing an engine in neutral can cause damage - and misunderstand the reason. They think its because an engine turning a certain rpm, say 6000, without load is more damaging than that same rpm with load. What they are failing to understand is that without load, it's going to a much higher rpm unless limited - that's what I was trying to get across. IOW - It's not the fact that it's not loaded at a given otherwise safe rpm - It's that not having a load will let the rpm go way too high and destroy the engine.D76G12 said:...As for revving in neutral - I can't tell you why it's bad but I've always heard it is. If it's a tall tale then it's a REALLY old one...
Yeah - but how much h.p. does it take to spin an unloaded engine to destruction? You might be right - I'm not speaking from experience. But even if it didn't throw a rod or spin a bearing, I bet it would take some life off of it to push the pedal to the metal for a few minutes (without some rev. limiter on it).alarkyokie said:"Also, if the gas pedal were floored and there was no limiter, the rpms could go to some catastrophic level - 7000 - 8000 - 9000 rpm with instant destruction (though probably provable).(peva)
Uh, I disagree... The upper engine limit will be when the engine is using all the fuel and air it can get...Look at hp curves and notice how it drops off as rpm gets out of range.
Mechanical efficiency, or something like that.. Now, add more octane, or alcohol, nitro, ether, Nos, and yeah, something will let go!
Are you sure? My original 2.7 saw more than 6500 on several occasions between 1st-2nd and 2nd-3rd. Of course I also spun a bearing the last time it went that high, but that's besides tha point. :biggrin:MikeW said:This is to protect the transmission.
The rev limiter on the 2.7 is 6500, 3.2 is 6900
Found out in reverse.
