Every year, the Race Pages staff visits the annual Motorsports Parts Media Council (MPMC) trade show in January. The conference is held in the Los Angeles area, and is a chance for media members such as ourselves to have quality face-time with many of the manufacturers that do such a great job supporting this fine magazine, the NMRA, and its racers. Each of the manufacturers on the premises has some of their new parts on display, and the unique format ensures that question-and-answer sessions are at the forefront of each meeting. Most important, the meetings allow us to plan out our editorial calendar with parts and pieces we want to show off to you throughout the course of the rest of the year. At the most recent conference, we met with our friends over at Design Engineering, the parent company of Ny-Trex Nitrous, and were intrigued at the layout of their Triple-Threat nitrous system.
The Ny-Trex Triple-Threat system has a number of unique features; after we spent some time inspecting the design, it went onto the list of products to explore for an installation and track test at some point during the year. Well—that time is now. We’ve hooked up with our friends at Brenspeed in the search for a car, and they turned us on to Brenspeed employee Brian Licklyter’s 2000 GT, which provided a great base for our nitrous experimentation. Although it wears a stock engine down the camshafts, it has already had a few external modifications performed to it, including a C&L plenum, BBK throttle body, and a JLT air intake. It also featured Bassani long-tubes and full exhaust, which makes it a great candidate for our project. A quick phone call to Ny-Trex’s point man Ken Brahier came next, and Brahier walked us through the parts selection, ensuring that we would have everything we needed to accurately test their system and remain legal and in compliance with all of the NHRA’s rules regarding the use of nitrous oxide on the dragstrip. Brahier set us up with one of Ny-Trex’s Triple-Threat EFI Wet nitrous systems good for up to 300 horsepower [P/N:110026], along with one of their Accu-Pressure bottle heating systems [P/N:120040], a Purge Kit [P/N:110080], NHRAcompliant blowdown tube [P/N:120092], blow-off burst disc [P/N:120091] and blow-off fitting [P/N:120090]. The plan called for an installation of the system and all of its associated hardware and then before/after track testing to finish off the data-gathering sessions. Oh, and of course, photography of the installation process to share with you, dear reader. Here comes the goodness...
We were curious as to the “Triple-Threat” moniker, but the confusion was quickly cleared up with an inspection of each part of the kit and its function. One of the “designed-in” ideas of the system is to make the installation as easy as possible for the end-user. With that in mind, the Ny-Trex gang combined all three solenoid valves (fuel, nitrous, purge) into one easy-to-install complete component. This saves a bunch of time and effort during the installation process—the valve assembly is pre-assembled and even features a slick weatherpack-style connector for ease of wiring. A precisionmachined billet body is the basis for the valve assembly, and each of the integral solenoid valves uses one of Ny-Trex’s Volt-Trap coils, all of which come together with the rest of the included parts in the kit to make up a clean installation. Ny-Trex ships the system with a 10-pound “Wet-Black” powdercoated bottle featuring a high-flow valve and liquidfilled bottle gauge. In addition, a fuel pressure safety switch, braided stainless nitrous and fuel-supply lines, bottle brackets, and every other item needed down to the drill bit and tap for the throttle-body’s nozzle installation are included in the kit. In a world where trips to the parts store to make “bolt-on” modifications work is the norm, the level of engineering and finish that went into the Ny-Trex parts list is impressive—we didn’t need anything additional to complete the installation.
There are a number of special features that Ny-Trex founder Brahier is very proud of and are included with the Triple Threat system, most notably the aforementioned solenoid design. The T-Rex nozzle design has what the Ny-Trex folks call a true-blend spray bowl. Brahier says this design delivers a “swirl-cone” nitrous/fuel plume at a 110-degree angle to the throttle body, which will flow enough nitrous for 300 horsepower, but still work great with a 35-horse shot (for those of you supercharger guys looking for the cooling effect). The plungers in the solenoids are made of high-grade alloy, with a Teflon seal on the nitrous plunger and Viton on the fuel side to prevent leaking. As we’ve already mentioned, a lot of thought went into making this kit easy to install, and the wiring has been designed in order to facilitate just that. Everything is clearly spelled out in the installation instructions, and about the only thing you’ll need to put this onto your own car is a basic set of hand tools, a drill, and a vise. “When we went to install the kit, one of the things that really impressed me was that all of the solenoids were combined into one easy-to-install and easy-toplumb unit. It saved the guys a bit of time and really made for a clean installation. We also really liked that all of the wiring was labeled. That made it easier for us also,” Brenspeed’s proprietor, Brent White, explained. Although our test vehicle featured the standard EFI V8 version of the Ny-Trex Triple-Threat system, it’s also available as a direct-fit, specifically- engineered system for the S197 Mustang [P/N:110029], and Ny-Trex has a variety of different kits including their two-stage plate system capable of 600 giggle- inducing extra horsepower for the adventurous racers out there.
TRACK TESTING THE TRIPLE-THREAT
After a few unfortunated delays, we were finally able to hook the car up onto Brenspeed's dyno for a quick thrashing before heading out to the dragstrip. With thr 125-horse jets firmly installed in the unique Triple Thread system, the bottle was opened, the nitrous armed, and the hammer dropped. Although we couldn't be onsite, Brenspeed's John Hulley handled the photography, track-testing was done by George Dockery, and we were quite pleased with the results. Brenspeed proprietor Brent White raved about the kit, explaining, "The car dropped about an even second in the quarter mile, which was awesome. We ran the 125-shot, and power picked up about 100 rear-wheel horsepower and 130 lb./ft. of torque. The only other change we performed to the car before the dyno session is to add a set of fresh one-step-colder spark plugs. This was not in part one of this article, and we do suggest using the colder plug with nitrous." The Brenspeed gang was very pleased with the performance improvement for what amounted to little more than an afternoon's worth of work. Both dyno runs and the dragstrip passes were completed with Brenspeed custom tunes loaded into the car's computer (one for the naturally-aspirated passes, and a different program for the nitrous-assisted runs), and these tunes are available via mail order through Brenspeed. The actual track testing took place at Osceola Dragway in Osceola, Indiana, where Brenspeed's George Dockery was behind the wheel and drove the car to a sweet 12.12 elapsed time with the nitrous flowing, a great 1.01-second improvement over the car in naturally-aspirated form.
