Well, he used his "Tommy Karlsson" engine in Supertwin Topgas since 2007, but wanted to step up in 2011.
So he build a new frame in the winter of 2010-2011, with a big supercharger added.
Last year he got some help off TMFC-driver Danny Bellio on the methanol fuel system and went testing in Bechyne, Cz.
Then Marc raced the Harley against funnybikes in the "Open Drag" class at Mosten race day in Denmark and managed to qualify with the top five, selected for the shootout on day two.

This year he planned to run the whole EDRS funnybike serie. So watch out for him in Hockenheim, he's with 13 funny bikes in a battle for an 8 field.
He's got it running 8.3's now, but probably will go faster with his new Puma cranck shaft, that will go in the engine next winter.
