The Optimizer: SCCA GT-3 Runoffs champ is in a class of his own


Collin Jackson at the SCCA US Majors Tour at Sonoma Raceway; June 29-July 1, 2018.

All of this begs the question: Who is Collin Jackson?

“I’m a technical guy,” he tells me, but would you expect anything less from a mechanical engineer? “My hobby is building and optimizing racecars – not racing my car. My sport is racing my car. Without my sport, I don’t have a hobby.

“I have a lot of stress in my job as president of a manufacturing company, so I go home and work on my racecar, or a design for my racecar,” he says. “I do something where I can totally forget about work. My hobby is a very internal thing. My passion is proving to myself that I have the ability to optimize something at a very high level.”

To that end, Collin is quick to quip that he’s not a fabricator. “I’m a fabricator’s assistant,” he chuckles. “I work with Andy Pearson – he owns Specialty Engineering which built the car. He’s a consummate designer. He’s just spectacular. Why would I weld on my racecar when I have an artist who can do it?”

Essentially, Collin explains to me, Specialty Engineering is the execution of his projects, but, he says, “I maintain my own cars; I strip them down. Do I rebuild the engines and put them on a dyno? No, Specialty Engineering does that. But 100 percent, I maintain my own cars.”

The word “optimize” comes up a lot in conversation with Collin. “I’m an optimizer,” he explains to me. “My results are based on Andy’s and my ability to build something that does what I want it to do. It’s not based on my ability to drive around a chassis that doesn’t work.”

OK, I say, tell me about optimizing for the SCCA Runoffs. Tell me how to win. “It isn’t all about me,” he says quickly, “it’s about my team and their ability to execute the plan. When I go to the racetrack I have a plan and a setup, and we execute those at the racetrack. I don’t do things on the fly – I’ll come to the Runoffs with a plan that’s prewritten.”

Collin develops a plan for each individual day at the Runoffs, down to the session.

“We’ll go [to the track] and prove what we know is applicable, then we’ll set a bracket of what I need to do if the track is slick, or whatever,” he says. “And then, every day, we try to execute an improvement to the previous day. It’s very much an iterative engineering process of optimizing the setup that we came to the track with, using the data that we’ve learned during each session.”

At this point, my weakness as an interviewer was showing. Posed with general questions, Collin returns general answers. Digging for details, I then struggled to tell whether the answers were specific or vague. But I dug nonetheless for Collin’s list of items to optimize.

“I like to put variables in a spreadsheet and start checking them off,” he says. “Shock absorbers, aero, brakes, suspension tuning, engine tuning, friction loss, tire construction – there’s a massive list. There’s no detail too small to optimize, and then re-optimize.”

Then, pay dirt. “It isn’t about lap time, it’s about race time,” he says as I feverishly jot down notes for my personal racing advantage. “I look for what’s the fastest over the race duration. I’m always about winning the race, not the lap. Nobody knows who led the first lap of the Indy 500, but everyone knows who won.”

There’s more. “If you’re tuning, you want to optimize one thing at a time. If the car is under steering, then you don’t want to do two things to get rid of understeer; but if the car’s doing one thing at slow speeds and another at high speeds, you can do two different things that affect them differently.” But done incorrectly, he points out, you can quickly turn one test day into two more.

“Racing isn’t just engineering your car, it’s also learning the difference between your car and your competitor’s car,” Collin tells me as I silently realize I’ve been doing it wrong for years. “If your competitor is 2mph faster than you down the straight and you take all of the downforce out of your car so now he’s only 1mph faster down the straight, you’re still going to get beat down the straight and now you’re going to get beat in the corners, too. You do the opposite of that.”

Then came a shocker to me: Collin isn’t a big user of data acquisition (“I find it to be very valuable but very obsessive, and therefore very unproductive,” he says); instead, he sings the praises of race simulators. In fact, he credits simulators with much of his success at the 2017 Indy SCCA Runoffs, although it wasn’t easy.

“I spent probably two months developing a car in a simulator that I thought handled like my Nissan so that I could do testing at Indy,” he explains. “It took me forever to find a car in the program. I ended up running a German touring car that had been de-rated to 300hp, I put super hard tires on it, and made a whole bunch of suspension changes.” He dialed the virtual car in using tracks like Sonoma and Laguna Seca, and then once the car was sorted, he loaded the Indy road course. “It turned out to be quite applicable,” he says.

You already know how it ends: Jackson wins. But seeing it happen is something else.
