ProCharger introduced us to their new D1X System at PRI 2022. They sell it as complete a complete system thereby eliminating the grief of trying to make it work on your own. 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.
Back at the shop, we switched directions on a 370 ci turbo build that was underway and finished it with the ProCharger instead. Once on our dyno, it pushed out 1,063 hp with no drama. We were very impressed.

Type: Engine Packages
Vendor: Borowski Race Engines
Description:
The shortblock we used is our standard boost-ready 370ci which 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. Both of these attributes make for a stronger bottom end. The additional counterweights reduce harmonics and increase stiffness. The net result is a stronger, smoother running engine.
The rotating assembly on this first build used Callies Compstar rods and Diamond pistons. We also use Manley rods and pistons for this shortblock depending upon parts availability and customer preferences. Our custom COMP hydraulic roller cam for boost provides a great balance of power across the RPM band.
The heads we use are RHS 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 (see video below). These heads are topped with a COMP BSR shaft rocker system which stabilizes the valve train at higher RPM.
This first engine was assembled using a Holley Lo-Ram intake. This family of Holley intakes can easily accept air-to-water intercoolers making them a popular choice for boosted engines. Other available intakes require less hood clearance and are usually paired with air-to-air intercoolers. Our dyno ran without any intercooling with inlet air temperature hitting 125 F. We can build this engine with a 417 Motorsports liquid-to-air intercooler as shown below or set it up for E85 eliminating the need for intercooling.

We used a Holley Terminator engine management system for the dyno. The complete engines we sell come with the tune from the dyno session loaded on these self-learning ECUs. There are a variety of Terminator X and X-Max options which can provide such features as drive-by-wire and automatic transmission control.

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.
