Supercharged ZR1 Corvette Supercharged LS9

When the C6 Corvette ZR1 went out of production, so did its unique LS9 supercharged engine. Chevrolet Performance acquired a finite number of them for use as crate engines and when they’re gone, they’re gone!

Rated at 638 hp and 604 lb.-ft. of torque, the LS9 is a beast!

The engine is a technological marvel. High-rpm-validated lightweight reciprocating parts, including titanium intake valves, are used, along with high-flow cylinder heads that draw the charge forced on them by a sixth-generation supercharger. It has a high-helix (twist) design that helps the “blower” deliver greater power at the low end and sustains it longer through the rpm band for broad, on-demand power whether off-idle or at speed.

Our crate engine assembly includes the dry sump oil pan and provisions for the charge cooler’s liquid cooling system. You’ll need an external oil tank and an external coolant tank to get it running in your project vehicle. It also includes a 9-bolt crankshaft flange that may require an adapter for use with some transmissions.
