Want to compete for wins in the Street class of Global Time Attack? The A90 Supra is cracking the code as the proven platform to be competitive nationwide. Jared Floyd's recent build proves that theory with his recent win at The Ridge Motorsports Park. It was his car's debut in the series, grabbing a victory over 14 other competitors. Jared's weekend was far from seamless, with multiple hiccups and roadblocks that prevented him from showing the car's true potential, which is scary for other competitors moving forward.
Jared has previously been a part of the Time Attack community, competing in a J-swapped Honda S2000. For as long as we've followed Jared, he has continued evolving that car. The development side of the sport is something that Jared seems to enjoy. He is a mechanical engineer consultant by day and develops products from racecars to neurostimulators.

When we asked him why he decided to move to a Supra, he indicated that his decision was all based on performance potential. "It's rear-wheel drive, short wheelbase (97.2″), good weight distribution, good power with massive power potential, lots of wheel/tire/brake clearance, low drag aerodynamics, good aftermarket support, and has a very fast shifting transmission," he told us. The GR Supra factory turbocharged B58 BMW inline six-cylinder engine is capable of 600+ hp paired with a ZF8 automatic transmission, packing plenty of punch if desired. "I built this car to compete in Global Time Attack Street Class, and other than being heavy, it should be competitive without massive modifications.
Jared's previous S2000 required a lot of R&D to make it faster. He wanted to avoid repeating those steps as much the second time. "In an effort to spend more time on track and less time fabricating custom parts, I chose the Supra as a platform because it already has the drivetrain aspects covered and can fit max width tires without modifying the body."

Jared's car utilizes the stock brake calipers with our Cobalt XR1/XR3 pads and Motul Fluid. It's been great so far. "I've run this car on track in near-freezing rain and hot/dry conditions and have had no brake issues. Braking power is more than sufficient, modulation is great, and no signs of fade. I think the biggest compliment for brake components is when the driver has no feedback on the brake system. When they work as expected without issues, that's a great brake system - what more could you ask for? I think more Supra racers should try the Cobalt pads."
He started the build this past winter and dealt with some supply chain issues, but he wanted to utilize the great aftermarket support for these cars. He ran into a few roadblocks when certain parts from one brand weren't designed to fit next to another brand's aftermarket part. "The other major struggle with this build is keeping the electronics happy. Everything is connected, and the car throws a fit when anything is outside the original parameters." As with any modern car, there are sensors everywhere now, and the factory never really wanted or intended for all of us crazy gearheads to start changing things.

"The Supra is surprisingly quick in stock form, but adding the P800 turbo with a custom tune by Bend Calibration dropped the 60-130mph time by over 6 seconds. That makes a profound difference on lap times but has some downsides in turbo lag and torque modulation coming out of corners." His favorite mod, though, is his APEX VS-5RS wheels. As we all know, for a car to be fast, it has to look fast. "The wheels are light, strong, look good, and reasonably priced, but when you pick them up and look closely, the details are really impressive. You don't see the details in pictures or even in person unless you look closely for them. I geek out on the side milling of the spokes and backside pocketing of the hub interface."
Jared conducted a few shakedown weekends on the car after the completion of the build in preparation for its first major event at the Global Time Attack Speed Summit on the Ridge in July. The gremlins started early in the weekend in Session 1. "My first lap was a 1:43.2 with lots of room for improvement. The second lap was a little slower at 1:43. 6. The third lap was faster until I hit the downhill compression after Turn 7, and the car went into limp mode with limited hp. There was no check engine light or warnings on the dash. That was it for session 1. The lap time was good for 1st place in Street Class by 1.5 seconds." After Jared did some diagnosis, reviewed the data on all of the vitals, and tried a few hopeful remedies, the result was still the same every lap with limp mode engaging in Turn 7. Then came day 2, where he swapped vanos solenoids and disconnected and reconnected all the wiring connectors related to the vanos sensors and solenoids. Unfortunately, the issue couldn’t be resolved. Jared kept trying and had a few 1:41s predicted on his Garmin Catalyst until Turn 7, when it would return to limp mode.

Jared's time from the first session was fast enough to hold up through both days of competition though, and he took home first place in the Street class over 14 other competitors. Certainly not too shabby and a positive way to end a somewhat frustrating weekend. "Once sorted, I think this car is going to be fast!" Jared exclaimed. He set the 4th fastest overall time for the weekend out of 51 competitors. “My current target is to beat the GTA Street Class record at the Ridge currently held by Amir Bentatou/RS Future in a K-swapped NSX at 1:42.602.” We're certain Jared will achieve that soon and officially claim the record at next year's GTA event. We will be watching the continued evolution of his Supra. We know he's got even more plans for it!
