X GAINS: Procharger’s D-1X supercharger proves to be an impressive performer in the extreme sport of building horsepower

Focus is an important part of everyday life, and when you’ve got a good thing going in one area, it can be all too easy to get caught up in a new project. Workouts are a good example of this, as concentrating on bettering one part of your body can leave the rest wondering what happened to the attention they also deserved. The racing world is all about focus and not just on the track. The car, engine, chassis, tires and numerous other details must be right for the best performance. But it’s all for naught if the driver loses focus.

For the past 25 years, Procharger has made waves in both the street and track market and about fifteen years ago, they arguably changed the racing world when they introduced the F-1X supercharger to market in early 2002.

“The drag radial world was just starting to get hot, and the technology in the F-1X got a lot of attention,” said Sergio Shifman of Procharger. “The F-1R was the high-end blower in our arsenal at the time,” said Shifman. “But the F-1X taught us what to focus on for future models.”

It didn’t take long for the racing world to want more power, and Procharger answered that call. “The technology learned in the F-1X marked the evolution of the next models of race blowers from Procharger,” Shifman admitted. “We used it in the F-3X to improve on existing F-3 series models, including the F-3 121, 130, and 136 blowers (even though they didn’t get the X names). We focused on getting the design of the impeller blade and the compressor housing to be as efficient as possible. Gearbox wise they were not much different from the previous designs.”

After tackling the biggest blowers Procharger offers, the company shifted to a new F-1 series model to gain a share of the smaller tire market.

“The next step was the F-1A 94, one of the strongest race blowers out there for the size,” said Shifman. Named for the inducer size, the F-1A 94 gained immediate attention in the Ultra Street and Ultimate Street classes, as well as X275 and even the NMCA’s Xtreme Street class—it was time to shake up the street market.

“With the success in the drag racing arena, we turned our focus to the street models, which is where the P-1X and D-1X were conceived,” Shifman said. What features can be incorporated from a F-3 blower capable of supporting over 3,000 horsepower to a model aimed at street and strip performance? Well, the impeller and compressor housing designs offered a considerable improvement.

“The gearbox design of the P-1X and D-1X is not much different from the P-1SC and D-1SC design,” said Shifman. The new designs saw in-house testing in 2016, and the P-1X and D-1X were officially unveiled to the public at the SEMA show in November 2016. The D-1X is rated to support 1,000 horsepower, placing it between the D-1SC’s 925 rating and the F-1 / F-1D models 1,050 thresh hold. And although it can make for a slippery slope on what model to pick, Shifman says the new blower is more than just the rating.

“The goal was to design a better blower for the low-boost kits designed for late-models cars,” Shifman admitted. “That was the P-1X, and the D-1X just became a scaled up version of that. Having a new 1,000-horsepower-rated blower in the arsenal is a cool result, and so far the results show the rating can be a little conservative.”

Procharger rates the P-1X for a maximum of 875 horsepower, an increase of 50 horsepower from the 825 ceiling of the P-1SC model, while the D-1X enjoys a 75 horsepower bump over the previous model. So how have the newest superchargers performed in real world testing on customer rides? Three shops checked in with reports, and Ford’s Coyote platform enjoyed an increase of 42 rear-wheel horsepower on an S550 model (2015-newer) Mustang by switching from the P-1SC to the P-1X. The D-1X is even more impressive, gaining 53 horses at the wheels on a cam-swap LS3-equipped Corvette, while a 5.7 liter HEMI Charger rocked the scales to 918 rear-wheel horsepower, a gain of 116 ponies when the D-1X was substituted for a D-1SC blower. If these numbers get your juices flowing for a P-1X or a D-1X, they are already available on the market, with Procharger also offering the ability to upgrade existing P-1SC and D-1SC models to the X goodies starting in 2018.

Daydreaming of more power gets our gears spinning, and an inquiry to Procharger revealed no one had yet to test the D-1X on a big-cube, big-block engine or a blow-through combination. Our 498ci big-block-powered project Boulevard Boost has been putting a D-1SC model through constant exercise since it hit the track in 2013, and seemed a natural choice to see what Procharger’s newest offering could do for the old-school crowd. Rollins Automotive Speed and Custom provided the use of its Dynojet for a day of testing, and we capped off the evening with a few blasts down the quarter-mile. The D-1X blew our predictions away, and we might just have to keep it on Boulevard Boost for a bit longer than originally expected.
