The team selected a suspension kit from UMI Performance as well as a limited-slip setup with more aggressive gearing for the factory 10-bolt rear end, while stopping power was dramatically improved by ditching the factory brakes in favor of modern four-piston big brake kit from Baer. Amaral convinced Pobst to liven up the V8 as well: Outfitted with a set of aluminum cylinder heads, a more aggressive cam, and an array of bolt-on performance parts, the Pontiac mill now cranks out about 400 horsepower and a similar amount of torque at the wheels. The team also selected a Sniper EFI system to give the Trans Am modern drivability.
“I didn’t want a carburetor,” Pobst explains. “To me, they just seemed kind of old fashioned. They can definitely make good power if they’re tuned right, but they don’t adjust to things like weather changes, altitude changes and, importantly, lateral g forces. So the self-adjusting aspect of the original Sniper system was a big selling point for me. And it ran really well right from the get-go. I loved that I could get in the car, turn the key, and it would fire right up and idle nicely. It accomplished all of our goals.”
After dialing the car and running a few autocross exhibition events, Pobst noted that were a few aspects of Sniper system’s operation that he wanted to fine tune. “We sorted out an RF interference issue by shielding the wiring, and I also found myself wanting a little more refinement in part-throttle situations, along with a little less resistance on throttle tip-in because it was tricky to make small changes. It was great on track, I just wanted a little more nuance from it at low speeds while cruising around town.” These traits weren’t deal-breakers from Pobst, though, who turned his attention to the oil starvation issues that he discovered while putting the Pontiac through the ringer on road courses over the next couple of years. Custom drain-back lines and an Accusump system took care of that issue.
“I recently found out about the Sniper 2 EFI system, though, and that really piqued my interest,” he says. “We had heard that the Sniper 2 was an upgrade in terms of its self-tuning capabilities, but the primary motivator for me was the improvement in throttle tip-in feel. So, we got a hold of the new system a few weeks ago. The installation was super easy – Nate had that done in our driveway in no time at all. It was a very simple, straight-forward swap. And it ran better pretty much from the moment I first turned the key. We were really impressed right from the get-go, and we didn’t do anything special – we just plugged it in. Before it was kind of tough to drive the car smoothly at low speeds, but not anymore. And it was a big improvement in part-throttle response as well.”
The Trans Am was also recently treated to a full suspension makeover from Ridetech that included a new four-link setup in the rear as well as triple-adjustable coilovers at all four corners. Pobst and Amaral also recently added subframe connectors for increased structural rigidity as well as a larger master cylinder for firmer brake pedal feel.
A Smokey and the Bandit-style wrap gives the Trans Am its iconic look, while the car’s nickname – Randit – was inspired by a serendipitous compromise that Pobst had to make when selecting a personalized plate. “In the movie, the plate is ‘BAN ONE,’ but of course that was already taken because there’s a million Trans Am guys who want that plate,” he says. “But ‘RAN ONE’ was available!”
Although it turned out to be a much more ambitious project than he’d initially anticipated, Pobst says that the Randit build is starting to feel like it’s almost done. “After installing the Ridetech stuff, I took it out on track at Virginia International for three consecutive days at HyperFest, and I all I had to do was put gas in it. I’m pretty happy with how it’s running these days.”

Looking ahead, Pobst tells us that the Pontiac will likely be making an appearance at Trans Am Takeover in mid-October. “I’m not sure if I’ll be able to be there, but I’m working to make the car a part of this super-cool event. It’s run out of the Summit Racing warehouse on the south side of Atlanta, and it’s kind of aimed at the ‘70s-era cars. This car might even end up on the turntable up front, which would be a huge honor. Usually, they use these incredible builds that have two hundred or three hundred thousand dollars invested into them, but this is a garage build that we did for a fraction of that. I had planned to do a track day with Nate that weekend, though, so I’m still trying to figure out if I’m going to bail out on that and be at the event, or if I can find a way to just get my car there.”
His racing calendar for the fall is quickly filling up too, with two Lucky Dog endurance events already on the roster as well as Targa Newfoundland rally race, the latter of which will see him piloting a modern Mini John Cooper Works GP. “I’m keeping busy, there’s lots of cool things going on,” he says. “I just feel really lucky that I get to do all this stuff!”
