turbo's actually lasting

So can we discuss upgraded turbo's that actually lasted more then 30,000 miles.
hexon
vargas
Rb
mmp
on3

feel free to add on to any turbo manufacture.
yes there are variables. Fbo + twins. and tuning.

But who actually has proven results. my bet is only the stock turbos.

So how much actual milage on your current setups?

Flame on,,,
I dont have 30k miles on hybrids. I'm sure not many people will be. I have 3000k miles on my RR700 Hexons. So far so good. However, if someone can figure out how to do something with the front diff on the XI I will then swap to a big single. For the best reliability nothing is going to beat the OEM setup. I had almost 90k on them most of them at about 18-19psi.

You forgot to include PURE turbos. I still have yet to read that a set of PURE turbos failed because of the turbos themselves.

yup prob just keep your WGDC under 40%... and then'll last longer... soo many variables... OCI what oil... psi....etc....

run inlets your turbo will be happier.

hexons r550 i have been pump gas this whole year... been to lazy too flash and run e85... but whats the point cars still faste then 85% cars on the road....

I think Pure is the only ones that I haven't seen a giant bitch thread about... Can't tell you how many RB, Vargas, Hexon smoke stories I've read.

Well its good to hear that is seems PURE is doing well.

I would assume more RB people would chime in as they have been around for quite some time.

You're going to have a bad time when you push a turbo well past it's designed operating RPM, while substantially increasing pre-turbine back pressure. Increasing the manifold runner diameter, increasing the turbine size & turbine volute a/r along with properly matching the compressor/turbine wheels is a great start to creating a reliable twin setup.

I have a lot of hope for the future of the twin N54 setup with these new cast manifolds on the horizon.

If you want a turbo that on average lasts longer than 30k miles, then OEM is the only answer, assuming you aren't running them at 100% WGDC.

If you want more power, then aftermarket is your only answer. Of the aftermarket options, Pure is only one from which I haven't heard of a failure.

If you want more power and OEM-like reliability, then you need to go to a single turbo.

Didn't Hexon essentially go belly up a week ago ("under new management") and instruct people to file PayPal claims to get refunds for outstanding orders which they won't be able to fulfill? Noticed they're website is still up though.

Yep. Hexon is out of business until further notice.

It's pretty shitty that they are making people file PayPal claims rather than refunding themselves. The PayPal process isn't exactly fast.

I'm waiting to see what people's results are with VTT GC Lites as well as the to be released Pure cast option. Ball bearings sounds incredible for longevity.

I have 116K on original turbos and getting a 30FF too often when I push 'em.

There are at least two pure turbo cars that have failed, one is just smoking but still running well after around 5k miles or so, the other I don't know much about.
