2,500 HP, Twin 83mm Bullseye NLX Turbochargers, 427ci LS7 Engine, Dart LS Next2 block, Emtron EMS

Type: Engine Packages
Vendor: Borowski Race Engines

Description:

This is a Drag Week type, full custom engine that can be built in a variety of configurations. It is still street capable, meaning it can operate on pump gas and  retains traditional head gaskets.  Both of these accommodations reduce the potential horsepower.
We modified it to track-only in its second season (copper head gaskets, O-rings, bigger injectors, etc.) and and it is this 3,000 hp rated version that is shown on the chassis dyno. 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 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.

This next video shows a similar build with twin 88mm Bullseye turbos and Cometic MLX head gaskets.  The head gaskets are why we only rate it to 2,500 hp although its obviously capable of more.  It features a BRE custom billet intake manifold.


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
  • Dual fuel rails
    One recent major advance with this engine is that it now 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.

    NOTES

    1. This engine is not pollution compliant and is intended for off-road use.
    2. All BRE engines are individually dyno tested and tuned.  Customers will be supplied with video of their engine's dyno along with the dyno and build sheets.
    3. Pricing is for the engine complete as shown and described other than that we now use a billet intake manifold.  It also includes the pair of Bullseye NLX 83mm turbos and an Emtron Management System with tunes for the intended fuels.
