3,000 HP, 427ci LS Engine - Complete, Race Version, Twin 83mm Bullseye NLX Turbochargers

Type: Engine Packages
Vendor: Borowski Race Engines

Description:

This is a custom engine intended to run on methanol but can be modified to run gasoline or any other needs you may have. Actual pricing will of course depend upon options selected, so the final appearance may vary as can be seen in the photos. The primary standard differences between this full race version and its more streetable 2,500 hp sister are the engine management system (Emtron vs. Holley Dominator) and the head gaskets.  Copper head gaskets with O-rings are used to more reliably handle high levels of boost, but they do require ongoing maintenance.  The Emtron system is explained down below.

We originally built the engine in the video below in a street-capable configuration.  It was modified to track-only in its second season (Emtron, copper head gaskets, O-rings, etc.).  Our dyno is rated to 2,500 hp so we weren't able to run this engine up to the boost level it was designed to handle. The customer was able to get his Camaro on a hub dyno and aired it out. Running 44 psi boost, he hit 2,737hp at the wheels as reported by Muscle Cars & Truck.

 As can be seen in the table below, even the numbers on our initial dyno break-in at low boost were pretty amazing.  
Fuel Boost Peak HP Peak Torque
 Pump Gas  15 psi 1,432 1,003
Methanol 22 psi 1,929 1,325

 (see attached comparative dyno sheet)

We ran without water to our dyno's intercooler in order to mimic what will happen in the vehicle, which has no intercooler.  Thanks to the super-efficient Bullseye NLX turbos, intake air temps never went above 110 F and the back pressure was minimal (< 2 psi).  EGTs were so low that the headers didn't even light up (see video below).  We also love their full ball-bearing design and patented adjustable MAP groove.

The performance story speaks from the data and videos.  What about "built to last"? That requires a combination of top-notch parts, engine design, machining, assembly and final dyno tuning.  Rather than write a book or brag about how good we are, here are some of the other parts/design highlights:

  • Dart LS Next2 block featuring Ford Cleveland-style main bearings with 1/2" studs
  • Dailey's Engineering 7-stage dry sump
  • Custom Callies Ultra billet crank with 4.00 inch stroke and I-beam Enforcer rods
  • BRE custom Diamond hard-anodized, full-round skirted pistons with ceramic-coated crowns and moly-coated skirts
  • Jesel belt drive
  • BRE custom Comp Cams mechanical roller cam
  • BRE custom All Pro CNC-ported heads with Crower shaft rockers, titanium intake and Inconel exhaust valves
  • Borowski custom billet intake manifold with dual fuel rails and blow-out panel
  • BRE custom Waterman fuel pump
  • Twin Bullseye 83mm NLX turbos with Turbosmart waste gates and blow-off valves
  • Emtron engine management system
As mentioned above, O-rings and copper head gaskets are required to handle this level of boost.  These are a maintenance item but do get the job done.  Here is a video showing how we do the block machining for O-rings on our 4-axis CNC. 





As mentioned above, this engine comes with an Emtron engine management system. The high processor speed and capabilities of this unit allow unprecedented control over all aspects of the engine's functions. This is particularly useful in allowing you to precisely and continuously control boost and torque while layering on features to enhance engine performance and protection. The wiring harness is also built to a much higher level to minimize electrical interference and withstand the rigors of competition.
