I've just read the comments on that video.
In it,the bike was running 0.8 bar of boost,which gave him 100BHP
It now has been wound up to give 130 BHP and he's working on an engine at the 'mo which puts out 170BHP!!!!!!
I'd like to see the Dyno sheets to prove all this,but coming from a land that climbs up 1 in 1 inclines,in Dragster engined jeeps who knows!
