The Performance Racing Industry Show 2018: What’s New and Cool Edition

Three nickel-coated StopTech calipers and two bottles of StopTech brake fluid
StopTech has rolled out another caliper in their C- line with the new C60.

StopTech’s new C60 caliper is the big brother to the existing C43. It features the same brake pad design as the ST60 caliper, while coming in at 3lbs lighter due to its improved engineering allowing for less overall caliper material. Despite being lighter than the ST60 caliper, the C60 is 16% stiffer overall.

The C calipers are initially being targeted for racing applications, but kits are being engineered with small wheel designs in mind (supporting 15-18″ wheels). The long term goal for these super slick calipers is to provide OE upgrades on factory rotors.

KW circle track coilovers on a display stand
KW has been busy adding circle track racing applications to their lineup.

KW decided that it wasn’t enough that they had crushed it in all forms of circuit racing, so they went after the circle track market in a big way. KW offers these twin-tube shocks as a pre-configured set of 4 dampers for sprint car applications, or can custom-valve a set based on the customer’s specifications. How did they figure out the sprint car configuration? By taking home wins in World of Outlaws, USAC, and several other sprint car series.

The circle track dampers feature independently adjustable compression and rebound damping. On the rebound side, low-speed damping is adjustable with 18 clicks of adjustment while a second valving stage is preconfigured to handle high-speed work. On the compression side, there is a similar 16 clicks of low-speed damping adjustment for tuning chassis support and tire loading. On the high-speed compression side, a preconfigured “blow off” valve helps to prevent overloading the tire and increasing overall grip.

Garrett GT55 stainless turbine housing
Garrett has released a new GT55 stainless turbine housing.

The folks at Garrett have a new GT55 stainless turbine housing. This monstrous turbine housing has been SFI rated and burst and containment tested, supporting shaft/turbine speeds of over 100,000 RPM. The 1.24 A/R housing has been designed to work with GTX 5533 generation 1 and generation 2 compressors, as well as the GTX 5544 generation 2 compressor. The GT55 features cross bolts preinstalled, which are a safety measure required by many sanctioning bodies. These cross bolts help prevent the turbine wheel from becoming a missile in the case of a shaft or other turbocharger failure.

From a packaging perspective, the GT55 housing includes Integrated threaded mounting bosses for bracing the assembly when installed in a vehicle. As the housing itself weighs approximately 40lb, one can see how simply hanging an entire turbocharger assembly off of a manifold would not be advisable. With a V-band inlet and outlet, this $2350 MSRP housing is available now.

Wagler Competition Products DX500 Duramax engine on a stand
Last, but certainly not least, is Wagler Competition Products’ beast of a Duramax.

The Wagler all billet DX500 Duramax pattern engine is an astounding piece of engineering work. The clean-sheet design is capable of a mind-bending 3,000HP and 6,000LB-FT of torque while spinning to an incomprehensible 7,000 RPM. And it’s a diesel. The motor is a who’s-who of performance engine manufacturers, featuring a mix of forged internals from Winberg, Wagler, Ross, Competition Cams, Trend Performance, and others.

The DX500 is a “dry” engine. There are no coolant passages anywhere in this bad beast. The block is actually a three-piece modular design, allowing for a top-third that houses individually serviceable cylinders. The head, too, is a Wagler design, providing more than double the flow capacity of a factory Duramax. If you have a need to pull extremely heavy things very fast and for a very short period of time, the DX500 is the answer. Look for an in-depth feature of this motor sometime in the future.

And that’s a wrap for the 2018 PRI show. What do you think? Did you see anything cool or interesting that we missed? Let us know in the comments!


  1. Actually if You have access to Peugeot Sport 208 R2 cars, rods and pistons for the Mini R56 were kind of available before Supertech.

  2. The best thing you can do to minimize wear on your solitary thrust bearing is to disable your clutch switch. This also reduced wear and tear on your starter, as the engine is no longer coupled loaded by the clutch on start up.

    Also, consider the fact that your solitary thrust bearing is totally dry on engine start.

    Of course, don’t disable your clutch switch unless you are a meticulous driver. I rock my shifter a few times before starting, to make certain it is not in gear.

  3. The 1FZ-FE was standard on US-spec Land Cruisers from 1993 – 1997. Titan Motorsports did some crazy drag racing development on that platform in the early 2000s as well.
