WTAC 2026 is done! With Reuben behind the wheel of his 2018 WRX STI we managed an event best of 1:34. Although this is just short of his all-time personal best, it doesn’t quite tell the full story...
.
The weekend marked a huge step forward in the development of this car. We turned the wick up with the car now pushing around 550 kilowatts at all four wheels, new coil overs for more grip and more aggressive aero. Chasing new records, the data from the car showed we were going faster than ever before and generating more G's through corners. Good news, right? Not quite!
.
That extra performance exposed a new weakness in the setup, oil surge. With the engine still not on a dry sump system and pushing upwards of 680KW at the crank, the engine was breathing extremely heavy. As soon as Reuben started pushing the car we were getting throttle closures just after the main straight out of turn 1. Further investigation showed the Emtron ECU was trying to protect the engine from drops in oil pressure.
.

In the quest for solutions we tested different breather configurations and changed the oil over to Motul 300V. These modifications paid off as we finally got a clean run, no pressure drops, no closure of the throttle, slotting us right into 7th place in club sprint class. We hit a staggering 284 Km/h down the main straight, faster than ever before with the car hitting the rev limiter in 6th gear! At these speeds, the forces from the aero are extremely high and the loads exceeded what the front splitter fasteners could handle with the splitter flying off in spectacular fashion just before turn 2.
.
Whilst frustrating, this is all part of the development process...finding the next weak point for improvement to get faster. We used the remaining sessions to gather as much data as possible however without the front aero, we couldn't quite achieve the same loads around the corners.
.
Now it’s back to the workshop to prep for Subinats with a new splitter in the making! Huge thanks to Reuben with his amazing coffee setup on tap, the team, everyone who helped across the weekend and the WTAC organizers for another great event.

From a 1:37 to a 1:33.63! A new personal best for our customer in his 2018 WRX STI at World Time Attack Challenge 2025. Built, tuned, and prepared by the Tunehouse team, this car has come a long way since last year! proof of what’s possible with the right setup, precision engineering, and driver dedication.

Big thanks to those who helped us get the car ready in time!

Photo dump of WTA. So much fun. Especially sharing a garage with @mitsuyoshi_nishio320 these guys battled so hard to get out there. Set an extremely impressive lap for how little time they got on the track. So inspiring to see. by @track.time
