Max’s Spec Racer Ford: Lose The Ego

After Max Gokhman signed for his 2006 Cayman, his dealer insisted that he take the car to the track. “You won’t be able to fully appreciate it if you don’t,” he said. Max was hesitant — the thought of balling up his brand new Porsche terrified him, but, at the same time, he sensed the man knew what he was talking about.

Max continued to mull over the prospect of tracking his new toy, but his dealer was adamant — so much so he offered to pay Max’s entry fee. That was all Max needed to make a decision. The next weekend, he took the Cayman to Infineon Raceway and began a love affair that never tested his patience. No crashes, no major repairs, and a relatively straightforward relationship with his parts suppliers made his first few years in grassroots motorsports a breeze.

Soft Ascent

After becoming the 2014 PCA Autocross Class Champion and multiple podium-sitter in various Southern California time attack series, he sold the 987 and moved into a 2014 981 Cayman. This time, however, he wasn’t as eager to modify the car. He’d come to understand the practical shortcomings of a track-oriented car and felt he might get more from the ownership experience if he was to leave the car mostly stock.

It was around then that one of his track buddies enticed him into wheel-to-wheel racing. This would entail buying a race-only machine. Truth be told, he had considered it for some time, but the thought of wadding up a Porsche racing car turned his stomach. Even getting on track in one would be prohibitively expensive, so he explored the cheaper options available to him.

He could drive a Spec Miata for a reasonable price, but he wanted something a little different. “I was looking for a mid-engined, purpose-built platform, and — and this is subjective — something a little more interesting than a Miata,” he explained.

He loved the idea of running a “spec” car: something that encouraged close competition through mechanical parity. What about something with the same power of a Miata, but in a car which weighs one thousand pounds less? The tried-and-true Spec Racer Ford, a staple of grassroots motorsport for the last fifty years, caught his eye. Mid-engine, open-top, closed-wheel, and very cost-effective; there was a lot to like about this diminutive, bare-bones racer.

Barest Bones

The tube-frame chassis has a 1.6-liter engine from a Ford Focus sitting transverse behind the driver. These sealed engines produce 135 horsepower, and are fairly inexpensive to replace when they go bang — though this rarely happens. The emphasis here is on reliability, low running costs, and complete driving immersion.

When Max first tested the car at Laguna Seca, he was setting competitive times by the end of the day.

The sense of occasion is something that can’t be underestimated with an open-top car like this. Not only is the visibility fantastic, but getting your helmet buffeted by the wind makes driving at seventy feel like a hundred and twenty. The information relayed by the car is detailed and constant; it’s easy to feel a locked tire or growing understeer through the steering, which is remarkably sharp. “Feedback is crystal clear,” he adds.

Sitting in the middle of the chassis and knowing exactly where your front wheels are at all times inspires confidence to get real intimate with other racers when going three-wide into a turn - truly what wheel-to-wheel is about.

Some might suspect that a car this visceral and direct would come with sharp edges. In reality, it is predictable and communicative, and, as it has much more grip than power, it’s quite easy to find its limits. When it does slide, it’s fairly progressive — more so than the Cayman; nearly 300 horsepower would cause a few dicey situations when passing in a late-apex turn. Some of this is due to a compliant suspension setup, and some of it is due to the Hoosier slick made specifically for the SRF. Incidentally, it isn’t the most expensive tire. Low weight and low power help lengthen its lifespan, too.

The sequential transmission by Sadev, standard in third-gen SRFs, is another racecar element that Max learned to appreciate. Unlike an H-pattern, which is lovely for canyon drives but saps attention from racecraft; or a PDK, which is clinically precise yet fragile on cars that were built for the street; the SRF gearbox lets you bang out shifts while bouncing off the rev-limiter with abandon.

Perspective Shift

Max admits that, while the Spec Racer Ford is the more engaging car to drive, he doesn’t have the same sentimental attachment to it as he had to his Cayman. “I save the sweet feelings for my Porsche. This is a tool to help me grow as a racer. I compare the distinction between the two to owning a pet versus owning livestock.”

And with the reasonable running costs, packed fields, low power, and full calendars, he’s looking to become a competitive amateur racer as he gets up to speed on the Spec Racer Ford platform, with the help of his team Accel Racetek.

“Once I got competitive with this hobby, I learned that money spent on coaching would make me a lot faster than aero, suspension, or other bits of kit. To me, some of those seem most like things to flex over. With Perry and Travis of Accel Racetek, I not only know that the car will be ready for the next race no matter what tomfoolery I get up to on track, but that they’ll keep nudging me to be a better driver.”

Ultimately, the moral here is that with racing, as with any other passion, dropping your ego — such as by going from a venerable Porsche to a humble Spec Racer Ford — may prove to be the path to success, paved with smiles.

Ed Susman's 718 Cayman: Proving the Four-Cylinder's Potential

Caymans are a common sight at Northern Californian tracks, but not many of them make over 400 lb-ft of torque. Though the six-cylinder variants have a grander sort of appeal, Ed Susman, a Subaru tuner with a penchant for turbocharged flat-fours, saw the potential in the new 718 chassis with the 2.5-liter engine.

Now, with a seriously wide footprint and suspension upgrades to match the gains in grunt, his turbo Cayman has been proven as a particularly quick car on both quick and slow circuits. Even better, there’s still so much potential with the platform which Ed, an obsessive tuner, aims to unlock.

Now that Ed has gotten intimate with this force-fed, four-cylinder midship, he’s been able to give this car a dash of the old 911 Turbo ferocity that makes it a very different car to drive. Unlike the atmospheric variant, this Cayman requires the driver treat the throttle with extra concern. Does one sacrifice a little mid-corner speed with so much power available? Possibly, but if there’s a delay in throttle application, the straightline advantage makes up for whatever difference there may be—and then some. 

The factory output—365 horsepower and 309 lb-ft at the flywheel—is nothing to sniff at. More importantly for low-speed tracks, it’s the way the motor just pulls from zip that changes its character so much. from that of the high-revving atmospheric versions. A flatter mid-range and a screaming crescendo isn’t what this motor offers, instead, it pulls like a sled dog from virtually everywhere in the rev range. Because it makes its peak torque figure from 1,900 to 5,500 rpm, it really doesn’t matter which gear is selected. It’s this ability to keep the car moving forward at about any speed is something else which cannot be savored with the old naturally-aspirated motor.

Not surprisingly, those figures were a little on the conservative side—just as Porsche is wont to do. After Ed got his hands on the motor, all it took was a downpipe, an E30 blend of ethanol, and a little tuning on the factory ECU to extract serious gains.

Of course, it wouldn’t be possible without Ed’s magic. The motor now makes 460 horsepower and 440 lb-ft at the rear wheels. Even wilder, the powerband has been broadened some; pulling harder from 3,000 rpm to 7,500. As crazy as it might sound, there’s still more mojo available—it’s just that the fuel system needs a little beefing up before it’s accessible.

Since the peak figure is available just shy of 2,000 rpm, it makes the delivery a little less than linear. Depending on the tires he’s using, he switches between two maps on the Cobb Accessport to soften the mid-range torque. If he’s using A052s or Supercar 3Rs, he gives it the full enchilada. If he’s on street tires, there needs to be a slight softening of the gradient of the mid-range ramp in order keep the rears from spinning everywhere.

Regardless of compound chosen, Ed had to throw a set of 305s on the rear if he wanted any traction in the second-gear hairpins. Thanks to Apex Wheels for giving him a set of 19X9 and 19X11” SM-10s, he was able to get the desired amount of rubber within the the factory bodywork without any rubbing or rolling. Somehow, they fit underneath the factory bodywork. 

More than mere meat, the secret to its inspiring traction lies in his clever throttle tuning. Now, there’s a more linear throttle position-to-output to make that horse-kick delivery a little more manageable.

With the car making serious horsepower with relatively little work, Ed now had a series of figures he could attract a whole new slice of clientele interested in making their Cayman dust GT3s on the freeway. His work had only really begun, though. To get the car to do what it’s supposed to do best, he had to improve footwork to complement the free-breathing motor. 

The list of upgrades is refreshingly short. With a set of camber plates; SPL control arms, camber arms, and toe links; and Ohlins Street/Track coilovers, he’s been able to make the car much, much more manageable. “Where it was nervous, it’s now neutral,” he declared. 

The footage below definitely conveys the violence of the turbo motor—even if the muffled soundtrack doesn’t. Ed has to tread carefully, otherwise the turbo motor simply monsters the driven wheels. Still, there’s a real playfulness to it all. Clearly, the turbocharged motor suits the Cayman, but it changes the emphasis from rolling mid-corner speed to getting the thing pointed and administering that power. While he might not be able to lean on it like he might in a similarly sorted atmospheric variant; it still looks predictable and playful. 

The car still has a lot of work ahead of it if Ed’s going to be satisfied. The front end simply doesn’t cooperate as he’d like, mostly in the high speed sections, and so he’s planned a bit of aero and weight reduction to help this car point as he’d like it to. For now, he’ll keep himself busy improving the deftness of his right foot—his brilliantly tuned engine is still grunty enough to roast the rears in fourth-gear corners.
