Hmmmm still Garrett based on a 2871.
Billet 71mm compressor wheel with extended tip, normal 6x6 blade configuration not full blade style.
Modified 53.9mm (standard GT28) turbine wheel.
Hopefully gain about 2-400rpm in spool and about 10-15% in airflow.
Hopefully have 30-35psi by 2000rpm, and pull like a 14yr old from 1400rpm instead of the 1700rpm now that it really gets into it, that's the goal anyway.
Not chasing HP really just torque, but if it makes a extra 20hp to give me 300rwhp, happy days.
750nm+ is the goal really.
Fingers crossed.

Marty
