BC2 with polt: 30.846, 31.520, 31.520 = 1:33.886
Jumped over all 3 ramps on my 0-shroomer

Edit: Man, i love the polt

It's extra speed makes it possible to get over both 2nd and 3rd ramp if you just release the MT late enough.
Edit2: 30.846, 31.503, 31.503 = 1:33.852

I messed up last lap badly. I was 0:01.3xx infront of my ghost after second lap xD
