Ouch!

more...

even more...

I'm not done yet...

So, how much extra power was this one pushing? I am assuming it wasn't yours.

The end...

About 3 times stock, but not for very long):h So, how much extra power was this one pushing? I am assuming it wasn't yours.

Bum deal for shere! Which rod let go, 7 or 8?

Both, but 8 had low compression (shortened rod) before it completely gave up.Bum deal for seer! Which rod let go, 7 or 8?

yikes. Hopefully I can avoid mine looking like that.

Dang you short rods! It's a good thing someone is working on that. Was there any pro-pain involved?

No "pain", but you can probably guess the other 2 ingredients...

Thank God it has a 100,000 mile warranty.):h Right? Right?:help:

its painful to look at-:t , what dont I have to do to have that happen :( !

Perhaps it was the diesel additive :)

It was the 22" spinners that caused it:phatyo:

Who's ride is that out of ben...anyone we know?? :confused:

By the way, nice pic of you giving the motor the business on the chain...):h
did the wife want the unit oiled up tonight or what??

been there, done that, sucks, similar pictures lests say

you say two bent, why is it always #8, and i thought lp was the bigest culprit

is there any better rods out there that can stand the stress of 750hp, water, lp

Ben you say 8 was bent prior, did he have any signs of it(white smoke when cold), rought idle cold

When I have something with that many holes, who needs the wife?):h

I dunno why it is always #8, but it looks like when the rod shortens, the crank weights contact the skirt and blow it right out the side.

Ben you say 8 was bent prior, did he have any signs of it(white smoke when cold), rought idle cold

Or how about that mystery tic from the piston skirt hitting the crank.

So we need shorter skirts :)

I have a 55gal drum of JB Weld on the way to you ...

Gm must want to see that one I'll bet before they warranty

I know who's it is and I aint tellin.....

Area rep said "no". I tried.Gm must want to see that one I'll bet before they warranty

Area rep said "no". I tried.

I kinda figured

OUCH! How much HP/torque we talking? Makes me wanna run stock!!!!!!!!!!!

actually when mine happened, their was no noticalbe knock or noise, just up and happened, turned a corner and 300 feet down the road it sounded like a pop, and truck stalled, i thought i just blew a intercooler hose off, then i seen the oil and coolant on the road, what a mess

A bad-ass HyperTech 60hp tuner and K/N air filter! : :joke:

I looked down at whoes on line, and there sure are alot of enquireing minds:rolleyes: , one little itty bitty pic of disaster and we all panic:eek: , kind of like when someone you know has a heart attack and the next thing you know you have chest pains all the time:(

Bad things happen at 3 times the rated HP/TQ... I will stick with 2 and 7/8ths):h

heh :D

I think that was true a couple months ago ...but now there have been at least 3-4 kaboom incidents all with the same or very similar results (lantern size holes in block and always #8 and sometimes #7) so think one could deduce there is a trend starting ... I don't think the masses have anything to worry about ...but get up there in the 600-700hp range and I think one would be wise to pay attention. If not, we will most likely see new/similar pictures on here soon enough :)

eric,

Weren't you looking to buy up some used dmaxs?

eric,

Yup, what ya got?

Max Payne,
I see you enjoy your work!

Damn! That thang is sure enough BLOWN UP!! Those failin' and flailin' rods sure make a mess. Good thing I only toodle around with only my Edge on level 3. Yep, I'm a poosey!

It is OK to love your job, but it is not OK to LOVE your job):h Max Payne,

Unless your a shepherd, or Mike L.!:D

Damn Max, all this looks familiar. We'll have to get together and compare kabooms.....

Tell whoever it is they have my sympathy... mine was non warrantable also....luckily no warranty block though!!!!!

Good God I can feel mine goin' soon.):h I'm dynoing just under 750/1485 now. In January when Air Research comes out with their new turbo, I guess it'll just be a matter of time (springtime) before I go Kaboom!:eek: Good thing I have a spare motor with no miles on it that I'm throwing everything I can at it. I sure hope we get some better rods and some type of girdle for these things before I run out of money and motors.

HOLY COW! That thing looks nasty!

Ok I am just going to say that looks really bad and I hope that never happens to me...

And expensive...HOLY COW! That thing looks nasty!

i found a used lb7 at the auto wreckers, cost was $7500cdn, and came with 101 day full warrenty, mileage on the motor was 4k, and i received the whole motor, new turbo, cp3, removal and install cost was 1800 dollars, GM wanted 24thousand dollars for the same job

their is lots of used lb7s out there, just have to find them, and said by others, when you play be prepared to pay, it would not hurt to have a second motor on hand for when the nasty happens

Dang. I know you know that i know who's it is. And to that person, I am really sorry to see this happen to an all around good guy..

#2 only on this new motor perhaps?

Are these problems with the water injection malfunctioning and causing a hydro lock, or are the limits of the engine being found on a constant basis? I agree with Juice on this one. I want to take my truck as far as it can go without drugs. Hopefully, wherever that ends up will not be over the line resulting in these disastrous results.

Eric was going to have rods made, but I'm not sure if they ever got built ---for those of you that wanted to know......

Ben, does your wife know that you've taken on another lover?

I would think if W/M was the culprit, given the size of the final destination... it wouldn't take much to hydrolock. If the jet decides to 'dribble' instead of mist... oh boy.... whammo.

Not for me. My wallet isn't that brave!

Propane on the other hand.. too much timing. CTD guys stay away from it like the plague... headgaskets don't like it.

Luckily I get to take power lessons from the CTD guys.
Safest is boost
Then NOS

Anything else gets spendy if it goes wrong.

What - 9300 bucks for a used lb7 engine!? Is Canadian money only worth a small fraction of US dinero, or are those engines sold by the pound (excuse me, I meant, "kilo")?

GM wanted twenty four grand to install a new engine? Amazing!

These engines can't be THAT expensive, can they?

Snapped rod in the middle...too much cylinder pressure. I'm surprised the wrist pin didn't pop first.

If you break a wrist pin on one of these engines, your my new hero.

Rods are already avail for a stock replacement purpose if you dont mind going heavier then whats in there...

ERic: any testing of them done, will they stand to the 750hp abuse, just add one, or should they all be replaced

I would think you would want to replace all 8 because of balancing issues, but I've been wrong before..

ouch. karl are you ok???????

That's a red Silverado... so it's not McRat :D

Let's just say if you go thru the NW Region section the truck has been in several dyno events.

So.........

None of this will happen to a stock engine, while towing?

Well....

"none will" is pretty absolute, but I think it safe to say that it is highly unlikely.

I'm assuming with that kind of carnage without "Pane" it would be a W/M Nitrous mix. I can only think of a couple people in that area that would have the kid of setup that would accomplish this and with it being a red truck I'm pretty sure I know exactly who it is, but since he wishes to remain under the radar my lips are sealed.

Sorry to hear about your loss, I'm sure you'll be back in the saddle in no time, maybe without the N20 W/M mix I hope!!

Cheers,
Wade

I talked to a guy that knows a guy whose sister's boss's cousin, twice removed know's this other guy and he said that it drove for three weeks after the initial injury (caught on a video on this sight) and that it was due to a bent rod that slowly progressed till the piston hit the counter weight on the fly wheel which is where ALL the damage came from. He would talk more about it but the MASS HYSTERIA that takes place around here would have everyone running for the doors. It was too much cylinder pressure on a weak area in the motor. Not a cracked block or broken rod. Will it happen again to a member here, you bet!

Who's next???

Nice to see you made it home with your new truck :)

so we can now say it was a tts tune that was in three weeks before:o:

Fred, Please don't throw stones where stones don't need to be thrown.

I can and will tell you that to high of cylinder psi is to blame. For some reason it happens to show in that area as is shown by all of our blown motors. Bent connecting rods then pistons hitting counter weights and then mass chaos.

:eek:


drugs are bad, mmmmmmmkay

trying to see if timing has a connection to the problems we are seeing with the bent rods

i have heard of another guy running a tune with to much timing causing the same results without drugs being used

then adding lp or water just magnifies the timing problem

any idea how much timing is seen on WOT with this tune

I would say extremes in cylinder psi is more the culprit. I dumped alot of stuff into to a small space in a very short period of time and with expanding gases/increasing psi something was bound to give sooner or later. To say I hydrolocked would be going out on a limb also. I would go into the physics side of this but it is pretty drawn out and more than i want to go into here. Maybe those stock head studs don't have a problem like we think but the stock connecting rods on the other hand. I think Eric's rods have alot of merit and if i had deeper pockets I would be in line for a set. But then what's the next weak link. Why always #8?

Man there has been alot of people watching this thread!!!

A huge THANKS to Ben Canty aka Max Payne for his butt busting work to get me up and running.

AND a big thanks to Steve Cole at TTS for his help too!!!

The truck is ready to see 900-1000HP in 06'.


Just kidding on the last part!!! LOL

This thread is a good read. Having been there and also saw the truck shortly before the ugly event, it was pretty awsome on the dyno. I too wonder about Water/Meth. I managed a huge bang and lack of a better word flame out running 50/50 water/meth and propane with my Juice on extreme. I had it stacked on level one of a Stelth quad at the time. Way too much timing. Clint from ATS was driving when it happened and I since have reduced the water/meth to 0% meth and got rid of the Stelth. I read in one of the earlier replies to this thread that head gaskets don't like propane? Anyone have any feeling on that? Ben is changing my head gaskets as we speak. Also having him pull the big injectors as well. CP-3 pump will not keep up, and there doesn't seem to be an after market fix that is reliable as of yet.

Fred I think that you're right. Too much timing is dangerous. I know that these motors can explode with just tuners alone and no drugs.

actually when mine happened, their was no noticalbe knock or noise, just up and happened, turned a corner and 300 feet down the road it sounded like a pop, and truck stalled, i thought i just blew a intercooler hose off, then i seen the oil and coolant on the road, what a mess
were you runnin a westers tune ? any drugs ? after how many dyno pulls?:eek:

at the time of destruction yes i was using the westers tune, but do not think it had much to do with the bent rod...

a month before that i was at the track running all sorts of stuff and at that time westers had a defuel around the 100mph, so not many runs were with it..

i did a lot of runs with the 210xxx Bully-dog stacked with the 150 vanAken, witch causes a lot of timing rattle, then add water injection and it sounds like a cummins 12valve, latter on i tried nitrous, right after that weekend i started to notice white smoke at start-up, witch is a major indication of a bent rod, lots of smoke till warm...


at that state... is when it needs to be looked at, leaving it just bends the rod more till it breaks or the crown of the piston hits the counter weights

hope that helps
