I recently had a turbo eat itself and pump metal into the intercooler on my f150. There did not seem to be any that made it to my intake, but I spent probably five hours cleaning my piping, CAC, oil lines to turbos, etc. I also filled oil and changed filter, let truck idle for 30min, and then changed them again to check filter for metal and watch for issues. I replaced the turbos with an OEM set i purchased on this forum and installed those with CRP wheels. I'd like to compliment CR performance on their communication, fair pricing, shipping time, as well as the quality of product i received. I have driven with these for last few weeks and would like to confirm that on my truck these wheels have increased the power of my truck noticeably according to my butt dyno. I also feel like they have a little quicker response on the same tune and also will hold 20psi when OEM turbos would fall to 18psi by redline. The Iat temps without meth stay lower, and I expect they are with meth as well it's just harder to judge with the dramatic drops on meth. Anyone on fence i will say that if you are already replacing turbos then I highly recommend these at their price point. As far as my turbo that failed, I believe the failure was due to foreign material damaging the compressor wheel and causing an imbalance that wore journal bearing to point of catastrophic failure.
