Type: Engine Packages
Vendor: Borowski Race Engines
Description:
PRI 2024 Show Special
ProCharger introduced us to their new D1-X Accessory Drive at PRI 2022. They sell it as complete a complete system thereby eliminating the grief of trying to make it work on your own. Our immediate thought was that we could build it using a liquid-to-air intercooler sandwiched in a Holley intake manifold. That would make it plug-and-play. No issues of how to stuff a big air-to-air intake under the hood somewhere. We liked what we saw and ordered one on the spot. We picked the 10-rib version over the 8-rib because you just can't have too much grip on a belt driven system. The build details are in the video below.
Edelbrock was teasing a new FAST intercooler / LSXR intake manifold combo at PRI 2023. They are touting more cooling capability and low pressure drop. It took a while, but we finally got our hands on one.
We always like lower inlet air temps and we have had great results with the FAST LSXHR intake manifold. Being primarily of polymer construction, heat soak should be minimal. The larger intercooler will however require about 2 inches more vertical clearance.
HOT TIPS - The latest version of this D1-X LS package (for sale) will be at PRI 2024 on the Maxima Racing Oil Booth and a flex-fuel version F1-X LS (sold) will be on ProCharger's PRI booth. The D1-X engine package will be available for delivery immediately after the show. This indicated price is only valid for the PRI Show engine. It will be going on our dyno as soon as we receive the intake pipe from our fabricator. Prices will be going up for all subsequent builds, so don't wait.
What's new for our D1-X LS build now underway? ProCharger has made some enhancements to the bracketry but the most noticeable changes are the FAST LSXHR intake / intercooler combo and our CNC ported AFR 12 degree LS3 heads. The higher flowing AFR's are replacing the RHS heads which were discontinued by the manufacturer.
The foundation is our standard boost-ready 370ci shortblock. It features a seasoned GM 6.0L block that we have digitally remastered on our CNCs. That includes full block prep and engraving on our Rottler 4-axis CNC mill followed by honing on our Rottler diamond, CNC hone. The latter has precision of +/-0.0001" and produces the exact finish we want time after time. The machining data is stored in the the machines' memory and the surface finishes are confirmed with our profilometer.
The crank is a Callies Compstar 8-counterweight with stock stroke. The additional counterweights reduce harmonics and increase stiffness. The net result is a stronger, smoother running engine. The rotating assembly is completed with Callies Compstar Extreme rods and Diamond R-series pistons. Our custom COMP hydraulic roller cam for boost provides a great balance of power across the RPM band.
As mentioned above, the heads we now use are AFR 12 degree LS3's which are surface milled and then ported on our 5-axis CNC. A key additional machining step is valve job & bowl blending on our Newen CNC seat & guide machine. These heads come equipped with a COMP trunnion kit to stabilize the valve train at higher RPM. Check out the machining videos down below.

The complete engine comes with the tune from the dyno session loaded on the included Holley Terminator X's ECU. There are a variety of Terminator X and X-Max options which can provide such features as drive-by-wire and automatic transmission control. FuelTech EFI systems are also available and provide additional features such as an integrated, waterproof display and more robust harness.
And yes, it will also be sporting our signature Borowski billet valve covers.

Notes
1 These engines are not pollution compliant and are intended for transportation use only in pre-pollution controlled vehicles.
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 Dyno results on the same engine are influenced by atmospheric conditions. The same engine can easily test +/- 2% different on horsepower depending upon ambient conditions. The engine you receive will have completed its dyno session at no less than 98% of rated horsepower with the tune we provide.
4. We also use Manley pistons and rods based upon availability and customer preference. The photoset and video shows the parts used in the previous build.
