OT discussion from LAP3 Turbo R&D thread

[Doel]

Extremely convenient that Lap3 pushes the shit out of them and not one has failed yet TWO with JB4 had "turbo" failure. All I am saying is coincidents don't exist.

I'm not about to argue whether or not coincidences exist, that's just absurd. I will say this, this forum has members mostly from North America, Australia, and a few Europeans. The JB4 is easily the most popular tuning solution on here, there are probably more JB4 tuned cars on this forum than all other non factory tunes combined (just an educated guess). All the blown turbos we know about are ones that belong to members on this forum. That alone significantly increases the probability of the JB4 being on a car with a blown turbo.

How many cars in Asia have blown turbos? Well we have no idea, but I'm willing to bet there are a few. Since, from what I've heard, LAP3 is the most popular tuning solution over there, I would put good money down and bet there's at least one LAP3 with a blown turbo.

Let's just agree we are a long way from having enough data to guarantee statistical certainty..

Lol what are you implying that 1 tuner did to 'blow turbos' that another tuner isn't doing? Do you even know what different factors can cause a turbo failure?

First of all these are not TUNES they are PIGGYBACKS and from your dumb question you don't how they work. Good luck but I would go with someone who has been working on KDM cars for decades than months.

I can barely hear you man, that hole you're in is so deep.

Piggyback, ecu, standalone, these are all different ways to tune a car. So yes, a PIGGYBACK is a TUNE. JB4 has been tuning high performance cars for a long time, tuning a Stinger is not all that different than tuning a BMW. LAP3 is a fine company, so is JB4.

Not the way to go about using a forum. You want to disagree, fine...but "...dumb question" comments should go somewhere else. AND... as will most likely be stated by several people shortly, a tune/tuner is a JB4, is a LAP3, is a Tork, is a ____.

My question to you about 'what makes a turbo fail' isn't a dumb question, I sincerely don't believe you know what would cause a turbo to fail.

Our office is next door to a Kia dealership. On the way in I normally see one or two Stingers sitting in their service bay. I doubt many are modified. Stuff breaks on these cars regularly and will continue breaking even if modified or tuned. Tuning your car does not create a magical protective bubble around it protecting it from any future mechanical failure.

Regarding the factory Stinger turbos out of over 600 now Stingers we've tuned I've still only heard of two turbo failures, both with similar symptoms. Loud turbo whine from one turbo especially when cold. One of those guys I know didn't take it in, added a JB4, did a short pull on map2, and his turbo gave out. Apparently in the chaos that ensured getting it to the dealer so much oil came out the dealer or someone let the engine run without oil and it developed a rod knock. Not sure what happened with that situation after as that was the last update I got.

Anyway we offer various maps on the JB4 for a reason, so pick your risk level. More boost generally equals more risk, but also a lot more fun.

In terms of how durable the motor is at 600whp power levels we're hoping it's solid as long as the tuning is good. We'll see as more people add these large aftermarket turbo kits and push things. Normally these power levels are where the extra JB4 safety systems we can implement start to shine.

This turbo whine that you refer to. I never heard it on my car until I did exhaust cutouts. I only hear it on a cold start and it goes away rather quickly. That said mine sounds similar to this car on start up.

Is that what your referring to or did they have a much louder turbo whine.

Thats what a normal turbo sounds like.

Every thread like this makes the forum dumber. Willy wanker needs to go back to whatever "KDM" hole he crawled out of.

My question to you about 'what makes a turbo fail' isn't a dumb question, I sincerely don't believe you know what would cause a turbo to fail.

High impeller speed due to high boost targets at high RPM, running lots of boost on cold thick oil, high elevation leading to even higher compressor speed when combined with the first, are usual suspects.

You weren't supposed to answer for him!

lol I guess I bailed him out. My bad.

Ohhh ohhhh what about debris hitting impellers ... like ice in cold climates?!?

I don't think ice is hard enough to hurt a turbo. I blend ice daily in my blender and those blades are fine, I'm sure a turbo can handle it! .... But why would you ever have ice in your turbo inlet?

Haha, actually the 2.8L Diesel Colorado’s bend the turbo ‘fins’ more then they should... and is suspected to be from just that... ice.

So it’s not reallllllly that impossible, the F150 EcoBoost’s 2013 CAC causes pressure drops so drastically condensation formed in the bottom and would suck into the motors... punching a hole in the block.... stranger things happen.

In all seriousness... if something (hard enough) hits the turbo wheel... it’s gonna fail.

I've seen turbos on other platforms explode from failed intake installs and things like that, but I didn't bother mentioning the obvious.

Haha, was definitely being obvious...

But that was a great bailout for him from you. PERFECT!

I've heard of turbos failing when running too much boost and getting excessive turbine temps, but usually this takes a while to kill a turbo. These couple failures happened very quickly, they would need to be running insane boost levels to cook a turbo that fast. That is IF the JB4 were to blame. My thought is a factory defect in the turbo and/or an issue with turbo's oil system.

Causation and correlation. Please learn the difference between the two. If you blow a turbo within 1000 miles of tuning a car the turbo was already on it's way out. And by "Tuning" I mean piggback, ECU reflash, dyno tune, or anything that causes a turbo to push more boost than stock. A turbo doesn't care what's making it need to build more boost, it can't tell if a JB4 or LAP3 or RaceChip or Tork tune is calling for more boost, it just spins faster and deals with the additional stresses the same way. But you clearly knew that already, yes?
