Here is what happened to mine. Photo's didnt work. will try from home tonight.

 

Hmm.

 

Here is a pic of whats left of the rod in the bottom of the oil pan . I will furnish more pics soon.

 

what appears to have happend is the rod gave. Cracked in half and then went to town on the rest of the motor. It cracked the piston in half, bored a whole in the crank and then shot out of the front of the block, finally coming to rest on the splash gaurd in the bottom of the car. The car has high miles and regular mods. Nothing crazy. No nitrous or anything like that has ever been on the car. Randy, I live is AZ buddy it never rains.

 

Based on post from minicoop78, looks like rod let go, not supercharger.

 

He wasnt responding to you but to Randy ...

 

Well I just got off the phone with 2 engines professors. They said basically your not going to have problems until you hit that one frequency range that the balancer is designed for. At that point you run a huge risk of engine failure, fatigue. The Tacoma Naros Bridge (sp?) is the example in this case.

It's a hit or miss thing. If you never think your going to hit that frequency then go for it, otherwise this is a bad idea. As said before, if your willing to run the risk then go for it otherwise don't.

I have decided against this mod at this point in the game. Call me chicken!

 

And that was the LAST thing the professor said before the bridge started swaying back, and forth, ... back, and forth ...

 

aye I wish there was a simpler explaination. If it works on one car, it don't mean it will work on yours. Tolerances and what not. I don't make the theory only think about it. It's for you to decide. :impatient

 

While all of what is said is basically true, the stock balencer moves the ressonance to an RPM below idle. Without it, it's somewhat above idle (around 1800 RPM, if I remember correctly). This isn't a place where the motor is particularly powerful, nor where it sits for long periods under high load, so it's of little practical consiquence.

Another way to put it, the Tacoma Narrow bridge would still be standing if the gusts only happended occationally, for a short time.

As one who has been around for a few rounds of this bar-fight, it seems that

1) The Mini motor is pretty robust in terms of harmonic dampener absence.
2) There is some information that the HB is there for the accessories, and NVH reasons.
3) There is no quickly growing pool of motor failures that are indicitive that this is a time bomb.
4) The number of miles driven with these on the car is increasing every day, increasing the statistical significance of the collected data pool.

So while the jury is still out, it's looking like it's tending to vote "Not Guilty!"

The same thing goes for a lightwieght flywheel though too. Your changing the harmonics of the engine and indusing different things. Ideally you need to change the balancer for that new frequency range.

 

Whoa, lets not go there. There are like 5 millions threads on lightweight flywheels and the only thing bad I've read is some clatter. ... OT

 

hmm....

after seen that comment about the flywheels, i think its time we disreguard this entire thread as it hadnt ever been here before.

this is only gonna cause more trouble.

 

sorry had to while it was there.

 

Yea I say they lock every argumentative thread like this until someone can actually prove that there is no affect on the engine or of any consequences as a result solely on this mod alone. Everything else is just hearsay and as far as I'm concerned BS. Just idiots vs. more idiots.

As a result of this thread I have put many hateful people on my ignore list (which by the way I didn't know we had), many of which were playing the poor me I am being picked on by others and I do absolutely nothing to prevoke it.

I am no longer going to post in this thread as long as you children keep bickering.

Why???? Its all healthy debate except for a couple of people bagging out on the topic starter and that nasty Pm.


John.

 

well you made me post again. My point is all you are doing is pissing everyone else off when all you do is argue about something very few of you have any clue about, and no evidence that it SOLELY causes or does not cause anything, there is no point to it. Therefore I have nothing to learn, and it is a big waste of time.

 

Well I for one think this is a great topic and worth debating!! Everybody can say their piece and then the individual can make their own decision on what they believe to be a reasonable gamble

To be fair there is no evidence on either side at this early point and we wont know for sure until quiet a few people get well into the 100,000 mile range, as to its long term reliability.

Good engineering sense says the dampened pulley can only do good. But it may still not be needed.

Cant see how this thread is pissing anybody off other than the people selling the product!! And We have the right to discuss the pro's & con's.

The only thing that should come out of this thread is educated decisions, everybody can decide if they are prepared to be a test mule or wait and see what happens.

I agree that with some exceptions this has been a rather interesting thread. Nothing concrete enough to make me not think that ALta,M7 and Randy Webb know what they are talking about or that their product will cause any abnormal harm should i decide to install it. What did cause me concern was the re posting of a PM in a public forum. In most of my other forum related areas of interest that is considered just about the most reprehensible thing you can do and cause for immediate dismissal from the site. No matter what was said it was a PRIVATE message. You should be man enough to deal with it PRIVATELY. In any event the rest of the thread was interesting.

 

We are very close

 

isellem is right my supercharger did go about 4 months ago.
we are talking about two different things.

 

I haven't anything of any real import to add to the technical part of this discussion, but I have to agree completely with conehead's statement above. I've been messing around with UseNet groups and weblists for a long time and I can't think of a single group in which it wasn't a serious breach of etiquette to post a private message or an e-mail messge in public. An unclassy thing to do in the extreme. Disappointing behavior to say the least.

Other than that and the usual and expected rampaging opinions based on no particular knowledge, it's been an interesting thread.

 

i think the conditions at the flywheel end of the crank are significantly different (flywheel, clutch, trans and drive loads) compared to the pulley end which is much less loaded: (accessories, sc, cam drive).


interesting opnion about the private message sanctity. I kinda liked it when Nixon's pm's were released.
