    • This is what the internals of a blown single turbo N54 engine tuned by Vishnu look like

      Everyone blows motors. Everyone. We have seen blown built motor supercharged S65 V8's from ESS-Tuning among engine failures from just about everyone for a multitude of reasons. That is why it is so important to make sure you have a quality tune on your motor as even if you use stronger aftermarket internals no engine is going to survive a bad tune. What happened here is up to debate and no doubt finger pointing will ensue but it is clear that something happened resulting in a blown motor.

      There are some big chunks of the pistons missing which certainly points to detonation as it looks like the motor beat itself to death. There is also some scorching and scuffing but there are many things that could have happened. Was the tune too aggressive and did the car run too lean? Was methanol distribution uneven and is that why some pistons look far worse than others? Not enough octane and continuous detonation? Faulty parts? Was the limit of these internals reached and surpassed?

      There are a million ways to spin this and this is not an indictment of Vishnu's tuning on the N54 although Vishnu's influence in N54 tuning has waned to the point of irrelevance. This is to educate that failures do indeed happen, everything has a limit, and as N54's with single turbos become more popular pushing the power output to well over double what the motor has from the factory means the margin for error becomes far smaller.

        Is it just me or has FFtec distanced themselves from Vishnu?

Same stuff thats in a meth kit. Bad and uneven distribution = kaboom. Doesnt take long at all. 4-6 were all pinging because they were probably all reading detonation from the broken cylinder.
        No, you can't. You can speculate as you're doing. I have cracked ring lands on several motors that looked like the above on cars without meth, therefor cracked piston doesn't equal a meth distribution problem. Detonation can and does happen in a single cylinder with others being fine. In fact, it's likely if you watch your logs. Meth flow is a possibility, but we can't say for sure from our couches.

        Another reason 100% E85 via the direct injectors is such a worthwhile upgrade for those pushing limits, regardless of your turbo selection.

        Meth distribution is a problem whether it caused this failure or not. Apparently this is eclipsing your grasp of the issue.

        Just say you have one. He said Vishnu had support. Fair is fair.

        Ha! I would rep this if I could, but I can't, so I won't.

        I'm still at work won't be back home until the weekend. I was running 100 octane gas at the time also. I will see if I have a log but the car drove fine with a little missing power. I didn't realize anything was wrong until I saw pure white smoke out the exhaust. Heavy tint masked it well. I will see what logs I have on my laptop but I don't believe I have a log for those last pulls. I don't know exactly what what wrong but with the amount of meth and race gas timing would be difficult unless it spiked somehow. I'm open to opinions and was hoping this could get some ideas. Oh it was cylinder 1 btw cylinder 6 was also a little down on compression too and the rest were perfect. I'll be posting a second motor here soon too that's blown.

        Ok so this is your motor in the OP?

        Hopefully the second motor isn't yours too? If so, damn...Jesus hates you.

        Yup, alcohol is a great lubricant if you are a homo sapien on the look out.

        Out of curiosity, OP, how old were your injectors, spark plugs, coils, hpfp, lpfp, valve cover and pcv check valves, etc and what was your maintenance schedule for oil changes and meth line/fitting teardown/inspection? Not trying to move blame or point fingers. Just trying to get an accurate depiction of the life of the motor along with the parameters of the tune.

        there are a good deal of people running shiv's tune on a single turbo and running higher pressures on upgrades twins that haven't had this issue. There are also a number of people who have had a similar failure with any number of the different tunes out there for this platform. I think that, rather than immediately pointing fingers, we should be looking for the facts and then see where the lead us, and not try to find facts that support our hypotheses. Just my .02

        He wasn't pointing fingers he provided who tuned it as people would naturally ask. He's actually been pretty calm.

        There were EVO's that survived Shiv's tuning as well. That doesn't mean all of them did.

        I'm not out to take anyone's side, but the big bold lettering calling out that it is Shiv tuned is definitely pointing fingers.

        My point is simply that until a point at which Shiv can be blamed, he shouldn't be. If it ends up being totally tune related, then he should be burned at the stake. Just a very one sided view on this board most of the time, which can be bad for novice readers looking for facts when there is so much bias. You feel me.

        What's he supposed to do? Say a magic tuning fairy tuned it?

        It's blaming him to acknowledge the fact he tuned it?

        Don't play dumb...you know damn well, and so does everyone else, that if a terry or jake tuned car blew up, you would not put it in bold like that. In fact, I'm sure it would be buried in the thread if you put it in there at all. I beg you to prove me wrong with a engine failure thread link.

        again, my only issue with pointing it out so strongly is that it leads the reader to believe Shiv's tune was the culprit...which we don't know, YET.

        Eh, Shiv earned that response from Sticky (and others). Should Terry or Jake provide the level of "service" and establish similar history, I'm sure they'd get the same treatment. Seems biased if you're coming in now, but there is something to be said for dealing with the reputation you earn. JMO.

        Incredibly accurate and honest response.
