"Flavour", as he's known at the drags, has always had great engines.
The funniest thing we ever saw was when they had their 8 year old niece(?) run in the Kitty Cat race. I don't think she knew to keep the "slightly" modified sled JUST in front of the next guy! ZING!! She blistered down the track at 25 mph when everyone else was barely scraping out 8 mph!! She already finished the race and was half way back down the return lane before the second place sled got to the finish line. LMAO
The whole crowd was roaring with laughter. Needless to say, they gave her a DQ for the effort.
So, bottom line is, if they are passionate enough to make a Kitty Cat go like stink (relatively speaking), I'm sure they put their heart into their work on bigger engines.
