Turbo vs supercharger on an NB—how do they drive?

Centrifugal/roots blowers give linear, immediate torque; turbos offer bigger headroom and adjustability. Both need fuel, cooling, and conservative tuning on stock internals.

How do I keep spool/response sharp with a bigger turbo?

Use efficient intercooling, short/tight piping, and a quality ball‑bearing CHRA. A well‑mapped boost control strategy preserves midrange without surge.

Do I need stronger clutch/diff for FI?

Higher torque warrants an upgraded clutch and a healthy Torsen or clutch‑type LSD. Monitor gearbox/diff temps and shorten service intervals for track use.
