Borowski Race Engines, Inc. strives to build the best engines in the world. If you are interested in billet blocks, you need nothing but the best. To attain that goal, we need to work with the best suppliers. Energy Manufacturing Ltd. is a sister company to Callies Performance, our go-to for cranks and rods. Ben Mens explains in this video why Energy is the best choice for a billet aluminum block for your extreme LS, BBC or Ford build.
First let's start with the raw material - 6061 aerospace grade aluminum-scandium alloy. Scandium alloys are used for extreme applications where lightweight, machineability, high strength and much improved heat resistance are needed - like Russian Mig 29 fighters and Smith & Wesson AirWeight 357 Magnum revolver frames.
Next comes the design and quality of machining. We are not fans of the lightening we see on other billet blocks. What's the point in taking off a few more pounds of aluminum? We'd rather leave it on rather than risk losing strength. Ben mentions chamfering as one of their items of focus. The reason is that any sharp edge is a potential stress riser and point of failure. A perfectly chamfered block is much less likely to fail - all else being equal.
The real point of competitive differentiation is heat treatment. Energy Manufacturing's T6 heat treatment is applied to the semi-finished blocks more than doubling their strength. The block is heated to over 900 degree Fahrenheit and held at that temperature long enough to dissolve and evenly distribute the alloying particles. It is then quenched, reheated to about 300 degrees and aged at temp to lock-in and size the particles.
If you watched this ad's video (March 2021), you heard Ben mention that we were using an Energy billet aluminum block for a methanol twin-turbo LS build. If you click BUY IT NOW, you can see the video on our website of the finished engine (and car) putting out an amazing 3,522 flywheel horsepower.You can also see a video of one of ourcurrent billet BBC builds.
We are authorized dealers for both Energy and Callies. We maintain inventory of high-end LS parts to get you on the racetrack and into the winners circle in a hurry.
