Another Time Attack weekend, another lap record. Our K-swapped Honda NSX continued its dominant 2025 season with a spectacular performance at Brands Hatch, delivering our third consecutive class lap record of the year and cementing our position as the team to beat in Time Attack.
The Machine
At the heart of our success lies the potent combination of Honda engineering and forced induction perfection. Tsuki, our NSX runs a BourneHPP K22 engine with a brand-new Garrett G35-990 turbo. What makes this setup particularly neat is our calibration system – a simple knob that allows us to adjust boost levels between sessions, giving us the flexibility to dial in exactly what we need for each run.
On our default Cal. 4 setting, the engine produces 593bhp at 1.2 bar of boost – already enough to trouble most competitors. But as the day progressed, we had more firepower in reserve.
The Mission
Coming into Round 3, we had clear targets in our sights. Our own Pro 2WD class lap record of 47.146, set back in September 2023, was the first milestone. But the real target was Colin Dorward’s Pro class lap record of 46.593, set in his Evo last year. Breaking both records would be the perfect way to continue our 2025 winning streak.
Session Breakdown
Warm-Up
Luke Sedzikowski, our driver and Tegiwa co-director, wasted no time showing our hand. A blistering 46.431 in the warm-up after just five laps of driving the circuit immediately announced our intentions to the paddock. The pace was there from the very first session, though, warm-up times don’t count toward official lap records.
Attack 1
When it mattered, Luke delivered. An even quicker 46.426 in Attack 1 not only broke our own Pro 2WD class record but also broke Colin Dorward’s Pro class benchmark. Luke managed 3 laps that were all in the 46.4 region so we knew we had the consistency. The NSX was singing, and we were just getting started.
Attack 2
The decision to bolt on brand-new Yokohama A005 slicks proved inspired. On just his first lap past the start/finish line, Luke found another 0.704 seconds, posting a sensational 45.722. The grip from the fresh rubber transformed the car’s potential, and Luke made the most of every tenth available.
Super Attack
For the ultimate session, we unleashed the NSX’s full potential. Switching to Cal. 3 cranked the boost to 1.4 bar, pushing power output to a massive 640bhp. Luke rose to the occasion, putting a crazy lap time in on Brands Hatch’s tight confines to deliver a stunning 45.556.
The Numbers That Matter
- Previous Pro 2WD record: 47.146 (Luke Sedzikowski, September 2023)
- Previous Pro record: 46.593 (Colin Dorward, 2024)
- New lap record: 45.556
- Improvement: 1.59 seconds faster than our previous best
- Margin over previous Pro record: 1.037 seconds
The Challenge
Setting these times wasn’t just about raw speed – Brands Hatch’s compact layout meant navigating traffic from slower classes throughout the day. Credit to Luke for finding clean air when it mattered and making the most of every opportunity to set a flying lap.
Looking Ahead
We’re now 3 for 3 in 2025, having set new Pro 2WD class lap records at every event this season. The consistency is remarkable, but we’re not satisfied yet. When we return to Brands Hatch in September, the target is clear: break into the 44-second bracket.
Before then, we’re heading to Snetterton for Round 4, where we’ll look to extend our perfect record-breaking streak. The BourneHPP K22 and Garrett G35-990 combination has proven to be a formidable partnership, and with Luke behind the wheel, we’re confident of continuing this exceptional run of form.
The Bottom Line
Another weekend, another record. The NSX continues to evolve, and our understanding of the car’s potential grows with every session. 45.556 is a time that would have seemed impossible just a few years ago, but with the right combination of parts (which are all available at Tegiwa.com), preparation, and driving skill, we’re rewriting what’s possible in Time Attack.
Roll on Snetterton – let’s make it 4 for 4.
