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 it retains traditional head gaskets.  Its 3,000 hp rated, track-only sister engine uses copper head gaskets with O-rings which can handle higher levels of boost.  Copper head gaskets, like setting valve lash, are an ongoing maintenance item.  The standard track-only build is intended to run on methanol only.  This fuel has much higher octane than pump gas so we can change the compression ratio.  The mechanical components of the two engines however are otherwise the same.  This should send a clear mesage that this engine is built to last.
We modified the engine in the video below from street/strip to track-only in its second season (copper head gaskets, O-rings). It is this 3,000 hp rated version that is shown on the hub dyno. Our engine 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 onto ProSpeed's 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 optional twin 88mm Bullseye turbos and Cometic MLX head gaskets.  


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
  • BRE custom Waterman fuel pump
  • Twin Bullseye 83mm NLX turbos with Turbosmart waste gates and blow-off valves
  • Holley Dominator engine management system
    This engine is also available with an optional 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.

    Call us today at 815-725-2727 and let's talk through your specific requirements, lead time and pricing for exactly what you want. 

    Have some time and want to learn more?  The videos below will give you additional insight into the parts and machining that will be used to build your engine.

    Methods of Payment Accepted: Wire Transfer, Certified Check, Cash with IRS Form 8300

    NOTES

    1. This engine is not pollution compliant and is intended for off-road use.
