OTS + Failed KMD is what's been destroying your engine. The little boost spike during the last WOT pull was probably the last straw that broke the camel's back.

Another note that I'll add to my details post:

When we pulled the ITV22's to check the plug gap, they looked very good with NO spackling. They were just gapped a bit too wide.

Good call. Post some macro shot of the plugs would be helpful.

Will do next week. I'm sure lots of pictures will be taken.

Dam man, sorry to hear that. Mine blew not that long ago.

i was dead set on getting these internals too. guess it could be improper installation tho.

[Nataphen]

In case you guys haven't heard, get Autotechs for fuck's sake. They seem to have less failures, and they back their parts with practically 100% no questions. Much less negative feedback than KMD.

erich is running ptp pump and making 700hp ... just saying i would get a whole pump and not risk your motor

^^ pro tip, gracias senior

Yep, that's the first thing I saw when I looked at the logs. I have the stock HPFP and I stay at 1700-1800 whenever I'm at WOT. Seeing that with the KMD internals tells me they shit the bed on him.

What version of the KMD internals are they?

Also, the FP was shit in the first log too. OP was at 17 PSI boost but just 1100 PSI FP. No bueno.

what should my pressure be with the internals?

damn it i hate it when people shit the bed!

[Nataphen]

It NEEDS to remain solid over 1600psi at WOT, but it's usually closer to 1800psi if they're working properly.

I think at WOT/high boost, you should always be around 1700-1800. That's what @Lex told me to watch for, anything dropping below 1700. You were at 1100 in both logs.

And this thread has reminded me -- I need to do some logging tomorrow LOL. Just to be safe.

[4G63]

I'm blaming it on that God awful silver grill Dbag towing the car looks like he laughing lol. Probably thinks it's "one of dem dadgom rice burners"

Best of luck man never good to see this happen and another Speed 6 ouch:/ Not saying this is it but everyone ALWAYS check compression before buying a performance based car in general. I'll check mine once a month still. You can never be to careful

[Tokay444]

When a fuel pump goes bad you'll actually see a rich condition, as you're not getting the atomization you want.
Raw fuel pools on the pistons until things get hot enough to explode.
I blame inadequate fuel pressure.

[17cak]

car has been running really rich lately and has alot of soot on the tips. even the hillbilly that welded on my cat today said something to me. the tow truck driver is one of my customers who does dirt track racing with a mitsu so he knows. charged me half price for the tow and even took home phate now thats service!

i actually said something to phate today how much i hate that grill! i want to paint it. it came with the car and if u remove it there is a huge hole in the grill.



anyway im more than ready to pull this motor i want to do it tomorrow and so does my little brother. i called him and asked him to take a picture after i left and he goes "one step ahead of u already took one, even got the cherry picker out cuz i thought we were pulling this motor today." he is currently rebuilding his small block by himself

[Nataphen]

You'll always have that soot, it's a byproduct of direct injection. Don't worry, most people here, myself included, have wondered that same thing, LOL.

[17cak]

well shit @Nataphen just drive down and we can party rock tonight and pull the motor out tomorrow like its no big deal!

[Nataphen]

I would love nothing more than to do that if I was closer. I eat sleep and breathe cars, bro. Some people have some other hobby like sports or poker, something like that, but I don't do anything except cars and beer, usually at the same time.

[silvapain]

Phate sent me a text about your car today 17CAK. I'll come down next Saturday and help you and Phate pull that engine.

[ppe4life]

sorry to hear that bro...but this is scary to read...i also have about the same upgrades (corksport TMIC is the differance) and just bought the KMD internals 2.1 thinking it will be safer, but guess not...
if you need some labor help let me know, as i only have basic knowledge on this and trying to learn myself...

[infeKteDx]

oyyyyyyyy, that sucks D:

May come and join you guys. The ol' lady is out in the field but she gets back i will talk to her about it.

have a crazy possible explanation just hear it out......

pooling fuel from failing pump (pools because not at ideal compression) , causes seemed to be rich occurrence, the incorrect gap for spark plugs almost saves this. fixed the afr/gaped spark plugs and started to tune. With extra fuel already in cylinder ecu thinks your fine, however inside combustion chamber runs near dry due to fp failure (1100 psi) with newly correct gaped plugs providing extra spark. Mucho spark with mucho air, no fuel= boom detonation

first thing i would do is pull the plugs, if they weren't roasted black id be surprised.
just a hypothesis, my condolences either way.

Damn that blows man :-( sounds like a number of factors...

Subbed for results...

[Paul]

Sorry to hear OP. subbed.

@phate and I hopefully averted a MS3 from going ka-boom today. Ebay DP... no internals. Don't give him more power than me! P

[driver311]

OP Im very very sorry for your loss. I know the feeling is gut wrenching.

Phate. Keep your head up bro. I know this has to be tough to swallow but these things happen it seems at the weirdest times. When I blew my motor up in dec 2010 the afrs were low 11s high 10s. Spark blew out just tiny bit and the car loaded up with fuel and then POW. Did you guys feel any cut right before it happened?

[polysynth]

Sucks really bad man...Hope everything works out for you man.

[jrlms6]

I feel for you, OP. Terrible situation. My wishes for a smooth and fast rebuild. Subbed for result.

You had a HFC welded into the M2 (ebay) downpipe? Did you get the cat at the shop that did the welding?

This just made me nervous about my autotech install...I now plan on designating atleast 2-4 hours, and will triple check everything.

[zenger]

I'll come over and lend my support as well. Since you have the mad scientist and the engineer I'll bring beer and we can cry together since we both blew our motors lol

[Lex]

Sorry to see this happen - a number of things were going on, overboosting with OTS map and intermittent fuel pressure from when the internals were installed caused a detonation event and probably several even before this final one.

I've seen quite a few cars blow with low fuel pressure and seemingly fine AFRs. At low fuel pressures the atomization is likely poor with less of the actual fuel being part of combustion but still registering on the WBO2.

Seems like the car will come out stronger and better setup in the end.

PSA: If you perform any modifications keep an eye on fuel pressure - it's a lifeline for this car. Even if you're tuned and with internals, it's still something to check now and again - especially if you're noticing any hesitation.

[08cosmic3]

OP, if your engine had to go then you are lucky to have Phate and crew around to help with the rebuild/swap, could not be in better hands. It seems we have had more 6's blow lately than 3's. The 6's are earlier models and I recall that the 2007 MS3's were blowing more often than other years.

No i ordered the cat from magnaflow. it was just a HFC nothing special. the same guy that did my cbe did my cat. we started up the car found a leak and re-welded the cat. then he checked the rest of the exhaust and found no leaks.

i think everyone is right, running a week on the crappy ots map mixed with bad internals did the trick. i did notice before the ap was installed, one day i was getting on the interstate and it felt like my car threw out an anchor. after that after time i got over 5000 rpms i had the same feeling. so i bought the ap thinking it would help, and then i no longer noticed it, only the hiccup.

[17cak]

UPDATE: got a call from the tech and he wanted to go take a look today. popped the hood and found 2 holes in the block. atleast with these new vents the car should run cooler!


here r two pics of the same hole. both under cylinder 4 on the right side about the same size

[keymaster]

Sorry for your loss OP, good luck with the rebuild.

Stuff like this makes me worry...my car at WOT continually knocks, I've seen 7-8 on the Dashhawk and I can hear the pings. Doesn't always happen, but it happens enough that I'm pretty careful when I go for it. I get knocking at partial throttle too in high load situations. But, when I log with the Dahhawk the boost, AFR and fuel pressure look normal, no spikes or anything even when it knocks. This was the way it was stock, and all I've added is a SRI, TIP and step colder plugs, and the car didn't look like it had any mods done when I bought it and I haven't found anything yet. I'm just waiting for the engine to decide to blow one day.

ANy vibes in the clutch pedal?

Seriously, if it's knocking so much you can hear it, stop going WOT and get it looked at.

Sounds like you could really use a tune. The stock tune is very aggressive and still doesn't deliver great power - so it's aggressive in the wrong ways you can say.

Sorry for your loss, Man. These things never come easy.
