EFR 8474 68mm Supercore - Aluminum

From the B2 EFR Black Series, the EFR 8474 dominates on the track and is well known for having a unique anodized black compressor wheel! This is an advanced ball bearing turbocharger with Gamma-Ti turbine wheel technology which greatly improves spool-up. EFR turbos have the competitive advantage over other brands thanks to the lightweight turbine wheel material which cuts turbine inertia in half vs. Inconel.

Gamma-Ti (aka Titanium Aluminide) is commonly used in aircraft turbine blades which provides strength and weight reduction. Since it requires less energy to accelerate the wheel, higher speeds can be reached sooner and as a result the on-engine boost response improves while the competition is reaching for the NOS button to catch up! EFR 8474 is sized just right for single turbo applications making 500 to 950 HP or up to 1,900 HP in twin turbo configurations! This turbo also is a top choice for 4 cylinder, 6 cylinder, single turbo setup, rotaries, twin-turbos V6 and V8s, and a variety of other race applications.

Key Benefits
