SEMA 2021: Edelbrock’s 1,100-Horsepower Concept Crate Engine

Just as we were ogling Edelbrock’s latest creation, a supercharged, 427 cubic-inch LS-based engine, which happens to churn out 1,100 horsepower, Edelbrock’s own Matt Patrick confided with us, “We’ve been known to do a really good job on the emissions-legal stuff.” But what we were looking at here, while it MAY suit the street driver, is actually more akin to thinking outside of the boulevard.

Edelbrock offers various crate engines with power numbers surpassing 850 horsepower with its supercharged LT416 engines. The line between street and race parts is becoming ever finer, and horsepower numbers are jumping into the stratosphere. The Edelbrock Group, which is comprised of well-respected names such as Edelbrock, FAST, COMP Cams, RHS, and TCI, decided to blend the company’s street-going manners with its “shoot for the moon” racing bend and ask the question, “What if?”

The RHS block features many accessory components from sibling Edelbrock Group divisions. The jewelry-esque RHS billet rear cover seals the back of the block while the accessory drive keeps the front all business. Between them both resides a Lunati crankshaft and COMP Cams camshaft.

The answer, which is the sum of all parts sourced from its various divisions, is this Concept Supercharged 427 engine. The RHS block is fitted with a Lunati Signature Series crank and rods, which wear a set of forged pistons to work well with the supercharger’s boost. A set of CNC’d Edelbrock Victor heads make the perfect mounting points for the Edelbrock TVS 2650 supercharger. A COMP Cams hydraulic-roller cam and lifters give the engine its marching orders while 16 FAST EFI injectors keep it safely fed with 93-octane pump gas – no special racing fuels here.

While a shopping list of go-fast goodies is used, the sum is definitely more than its parts with 1,100 horsepower at the ready!

Other Edelbrock Group brands offered their wares to bring this beast to life, such as the FAST 102mm throttle body, FAST smart coils, Fast plug wires, and a TCI racing starter. There are two sets of Edelbrock fuel rails, a -6AN primary and an -8AN secondary to feed all those thirsty injectors.

The 12-rib drive system used for the Edelbrock supercharger shows this engine is designed for serious duty.

While this engine may not yet have a part number, we were assured there are a lot of ideas on the table right now which will surely help blend that line between “street” and “race.” We’ll be sure to keep you informed as more information becomes available and as this new concept engine from Edelbrock has shown, the future for high-performance internal-combustion engines is brighter than ever.
