Default Collecting Stats on Aftermarket Twin Turbo Setups Reliability - 02-01-2019, 11:42 PM

I'm seeing lots of anecdotal evidence and vendor arguing online about who has the most reliable upgraded twin turbo setup. I want to try to collect some actual information on reliability by looking at manufactures and how many miles people have put on each companies turbos.

Please let me know if I missed a manufacture who you have had a good experience with and I will try to add them.

Here is the Google Form I'm collecting the data with.

I got 10k on mmp stage 3. Took 3 weeks from placing order to receiving them at the door. Running 18psi on e50, so I'm not pushing them at all.

I love love my pure stage 2 dd turbos. I have had them for over 2 years now at 20,000+ miles with no issues. Before I had the hexon turbo that last less than a month before them blew up.
