When we last checked in on Will Au-Yeung of PZ Tuning and his 9th gen Honda Civic, he had it on the dyno dialing in his new build and hoping to make tons of power. A transmission failure ended his tuning session at 705 horsepower and we wrapped up the article there. Since that time, Will has repaired the transmission, finished all of the carbon fiber body panels and aero, and even had some extra time to get it back on the dyno before the season started and managed to get an impressive 771 wheel horsepower out of the boosted K24A2.

Will took his Civic out for the first round of Global Time Attack at Road Atlanta to test his new setup back in May; and Speed Academy caught up with Will as he was unloading his Civic back at his shop just outside of Toronto. He had some ups and downs in Atlanta and learned a few things along the way, but an overall great weekend in the Unlimited FWD class.

On the first day of practice, Will hit 165 mph when his front splitter shifted back about an inch, disrupting the airflow enough to cause the entire car to begin to violently shake, forcing Will to end the day early to come up with a fix. Will reinforced the mounting points for the front splitter and called it a night. On the next and final day of practice, Will started off doing much better than the day before until his Civic suffered a head gasket failure halfway through the day. This was easily fixed, but threw away the rest of the final day of practice.

On race day, Will was being much more ambitious and daring. After being held up in turn 10 on a previous lap, Will was pushing himself and was able to hit 170 mph coming into turn nine, but quickly realized his brakes were overheating after blowing past his usual braking zone and locking up the rear coming into turn 10A. This threw the Civic into the sand pit runoff and destroyed the front splitter when it took the brunt of the impact.

The guys from the suspension manufacturer Fortune Auto were nice enough to run out to a local hardware store and pick up some supplies for Will to design a makeshift splitter to compensate. Will and his team were able to fix the damage and design a throwaway front splitter, but not before missing the second session by only five minutes. With only one full session left, Will was able to put down a respectable 1:28.056, giving him a second place finish in the Unlimited FWD class.

Since the race, Will has rebuilt the motor to prevent the overheating issues they were having and added stronger wrist pins to help stabilize the piston at high RPM. We’re going to continue following Will throughout the season to see how he and his Civic do once everything is dialed in.
