Different elements of cutting edge technology have come together in this 416 cubic inch, aluminum LS3 to create incredible performance, reliability, durability.
The Holley HP EFI system manages both the fuel and nitrous oxide delivery. A Nitrous Outlet puck in the base of the plenum delivers a HIDDEN nitrous shot. The EFI system only delivers N2O if the system is armed and sensors indicate wide open throttle at >3,000 RPM. System safeguards keep the engine protected in the event of loss of fuel or N2O. This combination of these two systems provides a huge jump in power when you want it. It also corrects all the reliability and durability concerns that have historically been associated with N2O.
The engine being offered uses a GM LS3 block (aluminum). It makes 620HP on motor and 845HP on a 150 shot of spray. A hydraulic roller set-up eliminates the maintenance and survivability issues of mechanical lifters. The reliability and durability are further enhanced by our use of quality after-market components many of which are have been finished machined prior to assembly at our state-of-the-art engine shop.
How can a naturally aspirated LS get what for the factory is supercharged power (ex. ZR1)? Our finish machining is a big factor. Every gearhead knows how important heads are in making power. Rather than trying to explain everything we do, let's focus just on what we do with heads after they come out of the box. This LS3 uses GM factory CNC ported heads, but only after they have received a custom CNC valve job on our Newen Contour. It can machine any profile and contour we want from the bowl up through the seats and to the deck. Because it uses a single point cutter instead of a form tool, the surfaces are geometrically perfect within our ability to measure. Unlike a form tool cutter, the single point cutter cannot possibly leave chatter marks. There is no reason therefore to ever "lap" valve to get them to seat properly. Bottom line, we see big jumps in flow and horsepower on any head this machine touches. Check out some of the pictures below to see what our CNC valve job looks like. Why doesn't everyone do this? These machines are very expensive and just buying one isn't enough. You have to know what to do with it.
GM typically hides their LS engines under plastic cover. Why? We think its because they are unattractive. Most of our customers like to show off what's under their hood rather than hide it. Our signature coil relocation brackets and billet valve covers show off our LS builds. Our custom billet serpentine systems are not only gorgeous, they too are top of the line performers. This one has AC, PS and what for us is our standard level 225 amp alternator. How many expensive serpentine systems are out there with 150 amp alternators that just can't handle the power load of normal street driving with AC, stereo, headlights, etc? Too many.
