Arnie Gonzalez calls it Pink-X. It matches. The truck’s crimson, and he autocrosses it. Plus, others have a look at the truck as if there’s a crimson X on it.
“They provide me the ‘Oh actually?’ look,” he says of those that first encounter his 1990 Chevrolet C1500 Sport. “They begin speaking crap earlier than they even see the truck run.”
Arnie doesn’t thoughts enjoying into their preconceived notions. “We do one thing on objective,” he says. “The primary session, we line up within the again. When it’s time for the second session, let’s say there are 25 vehicles and we’re thirteenth. We be sure we’re virtually the final one to tug up on the grid.
“They see this truck,” he continues, “and so they’re like, ‘Excuse me, are you misplaced?’ I’ll go, ‘No, however are you able to learn? You might need to have a look at the occasions. My truck is quicker than your automobile.’ They’ve this look of ‘You bought to be kidding me.’”
Arnie loves driving a wild card.
“While you received a Corvette, you’re going to be up entrance,” he explains. “When you’ve gotten a Miata, you’ll be towards the again. The truck is the unknown. That’s one of many allures of it.”
Champagne Desires, Beer Price range
Arnie grew up in Miami. His father took him into the paddock of the Grand Prix of Miami as a child, planting the seed of his ardour for all issues with motors.
“Being round Porsches and people forms of vehicles, I knew I couldn’t acquire these issues,” he says, “however I knew I may acquire a truck. A pickup truck is just not that costly. It nonetheless has a motor and 4 wheels. We’ve got a weight situation, however we are able to work on that.”
In his early years, Arnie had two profound influences. He turned wrenches for Pettit Racing, which fielded Mazda RX-7s for driver Cameron Price within the previous Grand-Am collection. Arnie additionally labored for California Customized Sport Vans in Fort Lauderdale.
“These are the fellows who fashioned me,” Arnie says. “I began to determine that I like my vans, however the problem was, how may I make my truck deal with like a few of these RX-7s or Miatas that I used to be surrounded by? It took me some time to determine it out. You couldn’t do that within the ’90s–the parts weren’t out there. You weren’t going to compete with a Corvette or Camaro–it simply wasn’t going to occur.”
Arnie raced Spec Miatas, however it didn’t excite him as vans did. As a substitute, 15 years in the past, he opted to construct Pink-X.
“After they invented the Miata, it wasn’t meant to be a Spec Miata. It become that as a result of the potential was there,” he explains. “I figured on the market was potential in that specific truck I run.”
Why the C1500?
Arnie loves many vans. Nonetheless, the 1988-’98 Chevrolet C1500, aka “previous physique fashion” or OBS, appeared like the right truck to change for racing.
“When in comparison with the 1973-’87 C10, the ’88-’98 C1500 is a better-designed chassis,” he explains, “and most of it’s firewall ahead.”
The C1500 makes use of a stiffer, light-weight, hydroformed body; the older vans don’t. And the place the C1500 received a welded entrance crossmember, the one within the older truck is riveted collectively.
Arnie says he may have gone with the mannequin that got here after the C1500, the Chevrolet Silverado, aka “new physique fashion” or NBS, however he went along with his private choice.
“The NBS vans even have a hydroformed body and have an LS motor, so sure, it will be a extra logical strategy to go,” he says. “Nevertheless it’s like, why would I take a Porsche 911 over a 928? Each are Porsches. Any Porsche connoisseur has a 911 inside their storage. It’s a love of the physique fashion. I grew up with the C1500. I wished that truck when it was brand-new. Plus, the newer vans are heavier.”
Arnie admits the truck isn’t for everybody. It’s not essentially the most inexpensive car on the market; he estimates it will take somebody $25,000 to $30,000 to construct one like his. It’s definitely not the best to arrange, both, and Arnie did most of that work on his personal. However vans are his factor, a lot in order that he promotes a truck-only Professional-Touring Truck Shootout at Beech Bend Raceway Park within the spring.
Creating Pink-X has been an extended course of, however Arnie has discovered methods to make the truck quick. Right now, it beats Spec Miata and 944 Spec lap occasions. In a latest NASA occasion, it bested a BMW M3.
“You bought to have a love affair for the truck,” he says. “You bought to have the eagerness to be the underdog and attempt to beat the BMWs, Porsches and Camaros.”
Arnie took us for a tour round his truck throughout a latest NASA Mid South occasion at Nashville Superspeedway.
Rear Suspension Swap
Arnie creates lots of his personal parts by his enterprise, OBS Chevy Racing. This equipment replaces the leaf-spring setup with a three-link suspension and coil-over shocks.
“The vehicles are typically extra even-keeled,” Arnie says of the load stability of vehicles versus vans, with vans having most of their weight within the entrance. “With the vans, that’s a significant drawback. We attempt to transfer a whole lot of weight off the entrance. Within the rear, we make up for it with mechanical grip.”
Arnie’s truck now weighs 3340 kilos. He says it initially weighed about 4250 kilos.
He continues to experiment with the anti-roll bar, generally operating with out it. He hopes to develop a brand new setup quickly.
Including Traction
Extra rubber usually equals extra traction, and Arnie moved to a beefy 315/30ZR18 measurement. He’ll both run Hoosiers (pictured) or Michelin Pilot Sport Cup 2 tires. To accommodate the broader tires, he makes use of a Belltech spindle, wheel spacers/adapters, and a wheel supposed for a Corvette. On all 4 corners, Baer 6P brakes–six-piston calipers, rotors and pads–up the truck’s stopping energy.
Framing
The OBS Chevy Racing body braces change the crossmember that holds the spare tire. This enables Arnie to shave weight but keep rigidity within the rear of the body.
Catching Air
Up entrance, Arnie added a splitter that his OBS Chevy Racing firm makes. Within the rear, a prototype rear wing catches some air and provides some downforce to the rear of the truck.
“I wouldn’t drive as quick as I’d with out the entrance splitter,” he says. “The rear spoiler is best than nothing.”
Serving to Geometry
The OBS Chevy Racing coil-over equipment up entrance, which incorporates billet aluminum higher management arms, permits Arnie to simply regulate caster and camber and set up coil-over shocks.
Keep Cool
This warmth extractor hood from OBS Chevy Racing does what it sounds prefer it does. It takes away warmth from underneath the hood to maintain the powerplant cool and pleased.
The Energy
Underneath the hood, Arnie constructed an engine from a 6.0-liter GM LQ9 block. The cast-iron engine was utilized in vans from 2002 to 2007. On prime, it has GM 243 aluminum cylinder heads, which Arnie ported. He estimates that it places out someplace between 450 and 475 horsepower.
Shifted the Shifter
Contained in the cockpit, Arnie stripped out a lot of the inside. He needed to transfer the shifter as a result of he opted for a Tremec T-56 six-speed handbook, which was extensively utilized in automobiles from GM, Ford and Chrysler. Arnie says he made the change for sturdiness, for the reason that truck initially got here with a BorgWarner T5 five-speed handbook.
