Warp Speed in a Box: Corvette ZR1 638-hp LS9 Crate Engine

The 638-hp LS9 6.2L V8

Listen up resto-mod and performance car builders! Beginning next fall you’ll be able to buy the 638 horsepower supercharged LS9, the new engine built by GM to power the 2009 Corvette ZR1. The engine comes fully dressed and needs only an external oil and coolant tanks, an ECU and wiring harness. The engine features roughly the same dimensions as the 6.2L LS3 so its installation possibilities are plenty.

The LS9 features a mind-blowing 638 horsepower and 604 lb.-ft of torque, more than enough power for winning bragging rights at the track or car show. The heart of the Corvette ZR1 is expected to be made available during the third quarter of 2009. There is no pricing available yet for the LS9, but a quick search of crate engines shows that the Z06′s LS7 is being sold for around $14,000 so expect to pay a bit more.

Here is the press release from GM Performance Parts:

GM PERFORMANCE PARTS SET TO UNLEASH THE SUPERCHARGED LS9 CRATE ENGINE

LAS VEGAS – The LS9 6.2L supercharged V-8 is the power behind the most powerful and fastest production car in GM’s history – the 2009 Corvette ZR1. In the third quarter of 2009, it will be available as a complete crate engine package from GM Performance Parts. It delivers a stunning 638 horsepower (476 kW) and 604 lb.-ft. of torque (819 Nm).

The LS9 crate engine will be the ideal all-in package for enthusiasts and racers who want the ultimate LS power plant for their project cars, from resto-modified vintage Corvettes, muscle cars and street rods to late model F-bodies and “shoebox” Chevys. The supercharger and charge cooler are integrated in the engine’s valley for a lower profile, allowing creative builders to fit the engine in a variety of applications with plenty of hood clearance.

The engine’s 6.2L displacement is shared with the LS3, but the LS9 is built for high-revving power with a supercharger. It uses stronger cylinder head castings and steel cylinder liners that are honed with a deck plate installed to maximize performance and cylinder sealing.

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. A new, four-lobe rotor design delivers 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. A dual-brick charge cooler is integrated on a unique manifold system that mounts the “blower” in the engine’s valley, with charge cooler on top.

GMPP’s LS9 crate engine assembly comes fully dressed, including the ignition system, supercharger assembly, exhaust manifolds and more. It also includes the production dry-sump oil pan and provisions for the charge cooler’s liquid cooling system. Builders will need an external oil tank, external coolant tank (for the charge cooler) and an ECU/wire harness.
