New larger turbos?

new larger turbos?
Who has upgraded their turbos? What gains did you get? did you do anything else to the internals?

Other than this thread - Stage 4 CRP Turbos Revisted (ZFGRACING) | Ford Raptor Forums - I haven't seen much else?

Full Race has a new promo out - 2017+ Ford Raptor / F-150 3.5L EcoBoost Garrett PowerMax Stage 2 Turbo Upgrade • Full Race (full-race.com) - I can swap turbos - but won't go into the internal...

Saw that this morning. My thinking is that I'm pretty much maxed out with power on the stock turbos and I'm not really sure how much more you can throw at the stock internals before it goes boom.

I have a set of the new Stage 5 CRP turbos (bigger turbine outlet w/same S4 compressor), manifolds, and CPE downpipes waiting for me to install them when the required OEM parts get here. I'm near the stock turbo flow limit, but they really heat the air to get where I want them to go. I bought the CRP setup to allow more overhead (for now), not necessarily looking for more power (on stock rotating assy), just want more reliability/overhead with my current setup.

Overhead? Can you elaborate? Thanks

It means I'll have more turbo/airflow than required, such that I can set the tune any way I want without worrying(too much) about the boosted air temps and/or exhaust manifold pressure causing detonation and ventilating the block.

Turbocharger compressors are great to provide boost to the intake side, but in doing so, the turbine also creates a high pressure in the exhaust side. If pushing a relatively small turbocharger to deliver high-rpm boost, the exhaust manifold pressure can exceed the intake manifold pressure such that the extremely high-temp exhaust gasses can be blown back into the cylinder and go BOOM!.

I did the stage 4's and manifolds plus the other normal mods. I'm also on e85, tuned it up to 570 but dialed it back to 530. If I did it over again, I'd just do an intercooler/HPFP and e85 and hit around 500.

I live near e85
