Not a terribly surprising result given the length of the race and the car configurations. For those of us living in A'murica (FUCK YEAH!), this race was 492 feet. For perspective, 1/8th mile is 660 feet and a quarter mile is 1320. It's hard to beat a good auto tranny in a street race. During early acceleration, you lose a lot of ground to slow manual shifts. 20 HP isn't going to make up the difference until you're well under way.
