2019 Super Lap Battle USA at Circuit of the Americas

Billy Brooks took out the Austin local COBB Porsche Carrera S development car to a 2:29.866. Yup, COBB proves out their products at the track. The car only had limited mods consisting of Ohlins suspension, AMS intercoolers, Akrapovic exhaust, Forgeline wheels with Bridgestone Potenza RE-71R tires, and a half cage and Recaro seat for the driver. The RE-71Rs are used by almost everyone in any sort of street class competition. I love them on Project S2000.

Mike Kang of Counter Space Garage drove out his new daily driver from Los Angeles to click off a 2:33.459. He had a CSF intercooler and I think brake pads, and that was it for mods. Mike was my instructor when I tested out the Ferrari 458 at Exotics Racing.

My buddy Chris is an Austin local and when I posted up on Facebook about Super Lap, he signed right up. He brought out his daily driver STI that was wheeled by Ryan Schimsk to a first place in Street with a 2:23.209. These Austin guys are quick and know how to build some cars…. The time was set using the low boost setting as high boost kept on popping off the IC piping. Like I said, this is his real street car and there’s not much opportunity to test out the high boost setting.

Johnny Hernandez out of SoCal landed in 2nd with a 2:24.070.

The turbo looks like a first generation GTX3582R. There’s a mix of parts making it all happen like the Koyo radiator, Killer B Motorsport air guide thing, and big IAG oil catch can.

A Radium Fuel Surge Tank keeps the engine feed with fuel.


  1. Honest question? Is there a lack of participation / competition going on at this event? Doesn’t seem very many serious competitors for the top spots.

    1. Looks like a total of 46 cars were entered. In reading comments on various forums, it seems the high cost of entry due to it being at COTA deterred some from participating. That said, I think the notable cars missing were the Professional Awesome Evo, PZtuning Civic which seems was in Japan and just set the Tsukuba FF track record, Chris Boersma Civic, Can-Jam STI. RS Motors Evo. Could any of them have beat the Lyfe GTR? Not so sure…. would have been interesting for sure. Hopefully they all make it out next year.

  2. Great article on a great event. I’m positive that this will become a standout event that draws everyone. SuperLap Battle USA, well done on taking what must’ve been a huge risk and making it happen. Khiem, so glad you were able to get there!

  3. Not too sure that radiatior on the Miata is going to be effective. Even though you have high dynamic pressure at the stagnation point on the front bumper, it the streamline would have to turn something like 80 degrees, into another high pressure zone under an unvented hood. I’m sure it works but it probably adds a ton of drag. I hope he builds a ducted hood vent eventually. Or you could do what Ferrari did recently with the 488 Pista and vent beneath the car. Ferrari claims 10% better cooling and 7%less drag. Another bonus is that the rear gets cool air instead of hot air which is denser, with less turbulence and entropy so the rear wing or spoiler becomes more efficient. The CoG is better too.

  4. I had to know what was going on with the SR3 Radical suspension. Found a pretty fascinating message chain. The original inventor chimes in at the end.

    The nik-link uses a bell crank to compress the top of the coil over as well as the coil over compressing from the bottom a-arm. This gives more shock travel to control the spring they say. The ARB is a tubular bar bent downward at one end and is mounted across the chassis connected to the bell cranks on either side. When the suspension moves the bar bends (bows) causing roll resistance.

    This is what I hate about the whole patenting system. The ‘nik link’ is identical in concept to the front suspension system Andrew Thorby designed for the early 90s Van Diemen Sports 200 car. He subsequently used the design on the Lister Storm LMP

    I did indeed use it on the Van Diemen and the Lister. There are a number of benefits, but on the front of the Van Diemen (and presumably the Radical) it allowed the good motion ratio of a pushrod linkage with the chassis simplicity of a simple double A-arm/coilover layout. Didn’t realise it was patentable though….
