Borgwarner Twin Scroll 7670 With Dyno Graph
I'm sure Borgwarner will stand behind it. From what I was told there hasn't been an issue with exchanges
No surge. I have it on my gopro.... back straight full throttle and then metallic whine. No surging or bucking etc....
weird. im scouring google for causes and a few were surge, over speeding, too much back pressure and thats all i came up with so far. either way, i hope its just an issue with the early ones and that its resolved. keep us updated with how the replacement works, i hope its trouble free.
I have a source that uses these turbos and I was told that BW said to really watch shaft speeds, especially if your using this turbo for track events. My source told me if I can run a Speed sensor, RUN a speed sensor, implying its pretty much a must.

Meaning.... if it was the cause you could look at the data and say....yep the shaft was spinning 10000000000 times too fast that's what caused the turbo to grenade. I have to imagine you're not going to have much warning? Anyone have insight on this?
Hmmm.. what good will that do? It simply measures the shaft speed right? It's not as though it can actively do something yah?

Couldn't a shaft speed sensor set to open wastegates/reduce boost/whatever so you don't keep it spinning if above X RPM?
Either way, good luck.
Any plans on uploading the GoPro Video? anxious to see it.

Yeah, it's just something to watch like a WB gauge. If its spinning too fast, reduce boost.
I wasn't emplying it was over spun Dave, just saying since someone mentioned about over spun shafts could bend.
Yeah not very many have the capabilitys to run that sensor.

it looks pretty easy to set up in a standalone. its a standard 0-5v sensor.
