🆚 Turbochargers vs. Superchargers: How to Tune Them Differently
If you think tuning for a turbo is the same as tuning for a supercharger… think again.
In this episode of On the Dyno, Bob Morreale walks you through the two major tuning differences between turbocharged and supercharged setups — and why understanding their boost behavior can make or break your tune.
Whether you're street tuning, building a track beast, or just want smoother power delivery, this video will give you insights that translate to real results.
Key Tuning Principles Covered:
-
Fuel Timing Matters
-
Superchargers: Fuel must lead the boost — target 11:1–12:1 ASAP
-
Turbos: Stay leaner (~13.5:1) until boost hits
-
-
Spark Strategy is Engine-Dependent
-
Superchargers: Delay advance early on to control knock
-
Turbos: Use spark to help spool, especially with oversized turbos
-
-
Optimize Before Boost
-
Pay attention to the pre-boost powerband
-
Tuning smarter here often improves spool time and drivability
