The Big Boss: Jerad Wittwer's 1,800HP Peterbilt & Performance Diesel Inc Shop Tour

What happens here

Jerad highlights PDI's dedicated dyno room, which features specialized water brakes and a 2000-gallon water tank for cooling during testing. He mentions that the dyno has achieved a record of 2100 horsepower from a big truck engine. He explains that PDI tests trucks for 24 hours a day at 400 horsepower for durability, and that this rigorous testing is crucial for optimizing their electronic tunes. He emphasizes that the decryption of engine control units (ECUs) and the development of reliable tunes are highly complex, requiring significant R&D. He also notes that PDI is unique in owning and operating its own fleet of semi-trucks, including trailers with custom hand-painted logos, which are used to haul PDI products and test their innovations in real-world conditions.

Goal: Showcase PDI's dyno testing facilities, electronic tuning capabilities, and integrated logistics.

I can't even imagine going 130 mph in a truck like this. >> On uh the back down in Weatherford, I was giving a guy a ride in a truck that's similar to this and I turned it sideways at about 155 and it scared him to death. Can you see the laser shooting around there on the >> Yeah. What is that? >> Just a light show for when you show them. >> It's just the detail is never ending. If you just look, you know, down here or underneath there, you know, or in the back, everywhere you look, it's just astounding the, you know, the fabrication and the detail. It's just I, you know, it leaves me speechless. >> And I've been around a lot of cool stuff, but I just I'm speechless. >> I am, too. I I normally have more things to say, more questions and stuff, but I find myself just looking at it and thinking like almost thinking nothing because I'm just looking at it and just taking it in. >> There's a kind of a crazy story about this, too, is we built this the frame, the engine, and everything. And then we hauled it to uh Connecticut and we teamed up with a guy named Todd Rocker Prairie and we built it together. So Carson went out there, my painter went out there, and then I would go out on the weekends and we kind of we kind of built this truck. together. And then it was, if you look on the dash on the other side, it has it custom built. I think it says on there for satin. I haven't even been back here yet. >> So, it's on everything. Like everything. >> Unbelievable. >> This is fully three-dimensional. Like every surface, top and bottom, upside down, is perfect. The only normal truck part I can see on it is the rubber on the airbags and the tires. That's like the only thing that is like shelf on this cuz the exhaust flow like to go through that thing. >> Uh, you know what? I've never cut it open to see how it flows actually. But it it definitely doesn't hold back. We probably should have inserted it some way, but we didn't. It would actually have that flow. I mean, a lot of it this truck never went on the dyno a whole lot cuz it was just for it's too hard on it for the looks and what it what it's…
