PostSubject: Jumped the rev limiter?   RPM limiter on Superchargerd 3.8 EmptyFri Nov 14, 2008 4:50 pm

Strange thing happened today. For reasons I need not name, I was revving the car up while in park and how it normally hits 4 and bounces at it it did not today. It hit 4, bounced off, hit 4 then jumped it and went up to like 6 or 7. After that, I heard a Ding ding ding but no lights were on. After I drove home I smelled under the cracks around the hood and it did seem to smell hot, but I can't place what kind of hot smell it was.

This is one of the more frightening things I've read on an automotive bulletin board. The reason for it is irrelevant. The fact that it happens at all is inexcusable.

I don't know that in the way you're thinking (i.e. I'm not a ricer retard who went out there and stepped it on the floor seeing where it would go - I know better). I have revved it up hard to see where it stops and then I let off but once in a while I'll do a double high rev and 4 is the stop when in park.

When I revved it up, I wanted it to hit the 4 like it normally does and as soon as it hit it I would've let off. Instead of just hitting the 4, it hit it and went over. What I wanna know, why did it do this and what was the dinging about? I don't see anything leaking either, but I'll check again tomorrow.

Go to the BMW, Benz, Audi boards, they'll tell you the same thing about hitting the limiter in neutral. It's bad, bad, bad. Most of those cars also have limiters in place to limit revs in P & N when the car isn't moving (in Buick's case, it protects against senility, in the case of high-revving imports, it's stupidity).

With HP capability increased more than 25%, my Riviera is running near perfect at 170k miles. I know the Euro/Asian cars brag about RPMs, but how many of them with really big power do you see on the road approaching 200k? Of those that have 150k miles, how much money do you think their owners dumped into repairs? Talk about being off your rocker...

Even if those cars like to be revved high, you don't own one. You drive a 3800 powered Buick.

You think they will be any diffrent? They are worse.... I hope you get a BMW . because then you may realize how reliable a Buick is.

Now we know what happened to the GP that "mysteriously" blew up. poke
I will assume the reason you were giving your car the "Torque Test " is even more stupid than you setting there revving your engine. twak

That dinging noise means you FAILED. bonk hi

PostSubject: Re: RPM limiter on Superchargerd 3.8   RPM limiter on Superchargerd 3.8 EmptySat Nov 15, 2008 12:20 am

I rev mine up like that sometimes. I use pulleys that are too small sometimes. I have about 180k on my car. I'm pretty much prepared for the consequences when and if they come. You only live once, I say. If I can't beat on my car when I want to, why drive.. I lowered my P rev limiter to 2750rpm. I don't really see much reason for it to be reved to even 4k in P.

I can only suspect that jump and dinging to be the product of some kind of electrical spike, glitch, or similar phenomenon. I wouldn't worry about it unless it happens again during another ricer moment.

The 4K "rev limiter" is really just a most basic safety. If you keep trying, it will rev past it. It's 'normal'. I think it has to do with throttle position, i.e. if you just floor it, the rev limiter enables. If you do light throttle, you can keep revving. i.e. you might have some reason to see what is happening at a high RPM and you couldn't get there if the rev limiter stopped everything.

PostSubject: Re: RPM limiter on Superchargerd 3.8   RPM limiter on Superchargerd 3.8 EmptySat Nov 15, 2008 10:04 am

In P or N with no engine load, the hydrolic lifters float causing the valves not to seat in time before the piston comes back to TDC. With the engine in gear the rise in RPM is much more gradual so you don;t have the problem. In cars that are modded you will find them running higher spring rates for the valve springs to further help out... especially ones with bigger cams. Revving in P or N is wishing for something bad to happen.

My car has 150k mi and I am heavily modded but I have no concern that my engine will fail anytime soon. The bottom ends of these 3800's can handle serious HP and the things that are prone to failing (valve train, transmission, timing chain, etc) are upgraded to make the higher HP in the first place. If you do it right you can make some HP with these engines regardless of mileage. It the people that don't mod correctly (lots of NO2, small pulleys without supporting mods, etc) that tend to blow their engines... they can do it on a car with 20k mi or 200k mi.
