His limiter isn't until about 200kmh. FWIW with the mods listed in your sig, even stock...he should have been able to take you. Might be true that he underestimated your car and stupidly didn't go wot right away. By then..it was too late. One way for him to prove it would be to get you to race again.

If I were you, I'd leave it alone and smile with your victory.
