I remember an article or blurb in the "What's New" section of SnowTech for a company that knurled the crankshaft lobes (balancers) to keep oil on them for better lubrication & reduce rotating weight.

Does anyone remember the company's name? I've gone through my mags but can't find the dang thing. I think it was a couple years ago....

Yes his name is Steve Miller from Michigan. Advanced Racing Technoligies. Phone 989 781 6936, he does excellant work.

was he the guy that made a supercharger crank?? where he drilled lots of little pockets on the wheels of the crank to help move air?

That's true, however it's been done at least 35 years ago, we used to have it done at Competition Cycle in Milwaukee, Wisconsin.

Advanced Racing AKA Steve Miller calls it Turboing the crank. Works on some engines and some it does nothing.

it works like a golf ball with the air flowing over air that makes it go faster because air flows over air faster than air over surface, some porting works better when leaving it ruff surface instead of smooth surface.

actually its to create a fan type effect in the crankcase and help draw in the fuel/air charge and sort of force the air fuel mix through the transfers. "Turboing" the crank, as Art and Steve Miller of Advanced Racing Technolgies call it.

thats cool and it still works the other way also

That may be true but the reason they did this(they werent the first to do this either)or offer the service is for what I described above. That was their thought behind doing it. This is a part from the 2002 Snotech magazine article which talked about Advanced Racing Technologies crankshaft Turboing.

"Turbo Cranks are one of their latest ideas. They drill a series of holes at a compound angle around the outer diameter of the crankshaft. The larger the crank the larger the holes. The theory is the holes act like a fan, boosting the transfer of mixture up into the cylinders. According to Steve, this achieves a pumping action that creates more vacuum, pulling more mixture into the combustion chamber. Increases of up to 2000 RPM's have been reported from many of the thirty engines modified so far. All they know for sure is it makes a difference."
