I'm looking at a single setup with plenty of mid-range power for messing around on the street and driving spiritedly through the mountains.
I've narrowed it down to needing about 84 lb/min of air and a pressure ratio of 2.2.
I've been looking through Garrett's guide for selecting the right turbo based on airflow and pressure ratios, but what dictates it being a low spooling turbo (about 3000-3500 rpm) versus a higher spooling (4500 rpm) when looking at compressor maps?
How much of the spool can be tuned buy selecting the right compressor and turbine housings?
Someone recommended a PT6870 CEA Gen2 for the above listed purpose, but $2400 is a bit steep IMHO. Willing to look at Borg Warner, Turbonetics, and Garrett as well.
