This one was a replacement for the last unit. I actually have two so if this one goes kaboom... i won't have downtime. I will read your post.

Can actually see the China turbo number "243" in the attached picture...
They've just stuck their own label over the top of the housing. Anyone can take a turbo apart and put a wheel on a machine in a workshop.

Just curious if you have ever delt in international trade? I do all the time I can tell you how it works if you like me to. Www.hmcwoodwork.com it explains how a product gets labeled a china brand.
Nah man these are quality stage 4 turbos rated 1000hp yo.
You all jealous of my 1k turbos cause I gap you.
Stop being mad cause your turbos that are expensive are called stage 2 thats like 2 stages slower then mine. I gap you all day with 2 extra stages.

Twins get a bad rep on N54s. Look at other platforms. Twins are king!
There's too many people running junk parts with big power tunes
There's too many people running the cheapest twins they can find
There's too many people running inadequate tunes
There's too many people not looking after their cars
Most of those people have twin turbos.
Most people who go with a single actually spend some time and effort getting to know how to best run an N54 and get good results
Yes but the twins you linked are both brand name turbos with well known reliability. Most of the twins in the n54 platform are getting cheaper and cheaper as are the cars so I only can imagine more twin turbo failures due to the combination of lazy maintenance and cutting corners.
What exactly caused the failure ? Its not as simple as 30+ psi. I mean, was it extreme heat ? Fuel not up to par for that power level ? Knocked due to pressures or cylinder temps, etc.
Just curious here, barely reading this thread. Thx in advance.
Agreed. Just curious to what actually caused his engine to blow. While there are many factors, its just like a body that got riddled with bullets. Which bullet caused the death, or was it bullets, fall, bump on head that actually caused death ?
1 main factor killed the motor. Curious as to what it was.
Ok guys, I will tell you why mine blew. No turns it wasnt high boost or bad engine, talked to the dyno shopping happend and to many other people, I then seen the dyno graphs and the reason was way too much torque and boost on low rpms. Mine was way too high and mistake had been learned and never do it again. I now have stage 4 DAW turbos. Car is back and turbos running strong. already has about 600 miles and I dont daily the car anymore so they are all mostly race and tuning log milea with some draggy 60 to 130 pulls and etc etc. Heres the turbos putting in work against 780 whp fbo e85 pulley 2013 gt500.
Thanks for the clarification. How much boost was targeted down low ? What Rpm ? Really curious to know the breaking point.
It was 30 psi flat boost on all the rpms. Yes it wasnt smart I never ever did that anymore. But the car is much more powerful now then ever before. Were going to the track this Saturday and see what she runs. I ran 11.3 and on the street without much trying I got 132.32 mph best trap speed. Not bad for just street run!
Thx, wasnt trying to make you feel bad or clown or anything. Just genuinely wanted to know. Everyone makes mistakes and it helps others learn from it.
Yes , car seems to be running strong !
This is nonsense. I've run well over 25 psi for 3 years on GC turbos and 23 psi on stockers for many years before that.
Firstly 25 psi tells you nothing but the restriction air flow is encountering at the TMAP.
Secondly 25 psi at 13 degrees of timing is very different to 25 psi at 3 degrees. You can run pump gas on that.
Thirdly 25 psi on a stock turbo is very different to on a 19T or a single.
Also it makes no account for the charge temps. An intercooler thats too small, bad fuelling etc will all make two cars running the same 'boost' very different.
Rods will bend at high torque but they will be alot more likely to bend if running high torque at low rpms.
So people shouldn't assume over 25 psi will mean a dead engine soon...
It's quite likely the heat generated during the pull was building up in the block and pistons. Probably caused the rings to start expanding and they closed up.
You can do a pull and be fine but do multiple pulls and heat can build up to the point of failure. Also once lifting off it may go really lean for a second or two.
Without full details its just a guessing game though. Some people can get away with tunes on ~35 psi and medium\high timing for a while but they seem to eventually let go.
