I was at the BIRA Circuit outside of Pattaya, Thailand on Saturday to cheer my friend, tuner, and sometimes driver, Khun Mac. He was the #1 qualifier, s usual. We have been discussing ways to make more horsepower on his (class restricted) 1500cc engine. The results can plainly be seen: the tall injectors which brought in a ton of extra torque above 7000rpm.
Khun Mac leading the field on the first lap.
A leaking head gasket kept him from winning . . . but he was still on the podium at 3rd place (and qualified for Sunday's big race). See more on my Khun Mac at BIRA Circuit blog page.
