Potential single turbo upgrade mentioned in this build, also mating to 8HP75.

keep in mind this will 100% be using a standalone ecu, we really need the ecu to be cracked before any turbo upgrades can be done

If the stock small turbos are pushing 28psi would doing bigger upgraded turbos allow you to run less PSI and make more power? 28psi seems like a lot of boost to push through a stock 3.0 motor but im not sure how good or bad stock internals are on the HO hurricane.

Interesting

All internals are forged from factory
Crank rod and pistons

Yes, but there is balance. You can run more efficient (larger) turbochargers at higher pressure ratios. There are variables but thoughtful setups mostly come down to an efficient compressor blade and reasonable A/R on the turbine, along with a displacement that can support it. I start with the engine variables (beyond displacement, head design and velocity is important) and back into the turbo that get where I want.

These newer Garrett’s are efficient for their size, but they are small. They have a bit of lag but are generally very responsive. Part of that lag is likely (would need to have an ECM hack to know) torque management. My guess is they COULD spool quicker, especially from a dig. I would envision this engine and transmission once tunable, supporting 800whp reasonably reliably assuming it’s not being abused, once tuned and appropriate fuel and turbo upgrades are available.

That was a great and informative read. Really appreciate that. You really seem to know your stuff!
