Borowski Race Engines Inc was first in line for an MSD AirForce LS7 manifold when it was unveiled at SEMA. Being who we are, we like to take great stuff and make it better. Toward the end, we had our friends at Nitrous Outlet pipe it for spraying a 200 wet shot of nitrous. This custom manifold then crowned a Dart SHP LS Next block and Brodix BR7 CNC ported heads for its debut at PRI2016 on the Melling booth. When this beauty came off our dyno, its tune produced 660 hp on motor and 880 hp on spray. That’s a handful for any street cruiser! Check out the dyno sheet and think about how it would feel to slam down 871 lb-ft of torque.
What about the rest of the parts? How about Callies Compstar crank and rods paired with Diamond R-series pistons? Keeping the beat is a custom Comp Cams hydraulic roller under our own BRE lifters, Trend pushrods and rockers dressed with a Smith Brothers trunnion kit. No needle bearings here!
We top those Brodix heads with our signature billet valve covers which support a set of Daytona Sensor coil packs and BRE custom ignition wires. Running the whole show is a Holley HP Engine Management System which comes with the tune from your engine’s dyno session. This is an amazing piece of technology as it turns nitrous from an untamed beast into a reliable power-adder. If the nitrous system is armed, the ECU turns the nitrous on and off at the preset conditions. It will also pull timing if it sees anything amiss. All this in milliseconds with no driver intervention.
Up front and center is the matching serpentine system with all the accessories. No skimping here either. The 225 amp alternator will easily handle the electronics typical for modern restomod. The PS pump can be ordered either with its own reservoir or with a remote reservoir and fittings for hooking up your Hydratech brake boosters. The serpentine system and valve covers are also available upgraded to a polish finish.
Down below, we will work with you to select the oil pan right for your vehicle so that it leaves our shop drop-in ready for you. Oil pump? Melling, of course. Have a specific color scheme in mind? We will paint the block and select the ignition wires to match.
The power of an engine like this puts a transmission to the test. Unfortunately, many will come up short. For that reason, we have worked with top transmission suppliers (Hughes Performance for automatics, Tremec for manuals) so that we can offer pairings that work. We designed this engine to be a cruiser, and for us that points to over-drive transmissions like our highly-modified Hughes 4L80e or Tremec T-56 six speed. If you can resist using the bottle and don’t go crazy on the gear ratio in the rear, you can pass everything on the road including the gas stations.
If you go with the 4L80e, the Holley HP can be upgraded to a Holley Dominator which can then control both the engine and transmission. This is a neat seamless package compared to having a separate trans controller. Hughes will also tune the converter to your vehicle specifications and planned driving pattern.
One nice final touch is the Holley Digital Dash. Worried about getting all the gauges wired up and working in your dash? Forget it. All the information you need or want to know is the Digital Dash which it can display through a variety of customizable screens.BOROWSKI RACE ENGINES, INC. LIMITED WARRANTY NOTES
