2019 Super Lap Battle USA at Circuit of the Americas

The old Crawford Performance STI made an appearance in the hands of new owners.

Cody Miles in his Garrett turbo powered and Air Lift Suspension suspended car ran a 2:24.093 for 6th. Cody did the OEM hood venting mod which I’m all for as the stock STI hood is nice and light.

Phil Grabow with Element Tuning earned 4th in Unlimited with a 2:17.077. Yup, that’s a LS swap into an FRS and it’s damn fast. The FA20 is kinda fragile, like 13B rotaries….

This S2000 driven by Jesse Selinsky put down a 2:31.785.

What caught my eye was the Garrett G25-660 turbo. It looks to have a PTP turbo blanket on the turbine housing to protect the valve cover from excessive heat.

An Evo!!! Back in the day, there were many more Evo time attack cars. I guess they are all hard parkers now? This one was driven by Earl Zimmerman to a 2:31.198 in Limited. I believe the Camaro ZL1 was wheeled by Brian Tyson to 3rd in Street with a time of 2:26.654. The ZL1 is a legit track machine straight from the dealer. Look at all the attention paid to cooling with the front bumper openings and the splitter and canards for aero.


  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….
