Will do. Fullrace has excellent customer service. Geoff has hooked me up. There was some mis-communication is all.

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.

The turbo was never over 35 psi here and left at 28 psi, I'd think that is well within the shaft speeds it is suppose to run.

Hmmm.. what good will that do? It simply measures the shaft speed right? It's not as though it can actively do something yah?

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?

just another parameter to watch and log. say it has a max shaft speed of 150k rpm and you consistantly log 130k rpm. you know you are good. either way, having to run a shaft speed sensor is absurd for anyone but a race team.

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.

I was reffering to the "new" GTX3576.... But yes! I would like to see a comparison on those two...

I think the GTX3576 TS T3 .82AR would be one bad dude. Something similar to the 7670 EFR!
