Is that 12 or so balancing holes he put in there?       Might have been easier to go internal?

Those guys are daring. That crank would never go internal, scat designs suck as they are based off old ass 600 gram pistons and very heavy bobweights, so you need to remove a shit ton of metal. The only other option is to take the crank to the lathe and cut the counterweight down but this is a very time consuming process. I wonder how many drill bits they go through with that spindle speed, holy fuck

Ahh yes, the rpm you are seeing is a calculated equation taken at 500 rpm then the balancer does some internal math to tell you how far out of balance it is and what the effect would be at those rpm's. You can not spin a crank on a balancer to 10k rpm, it would fly off the balancer and kill everyone within 10 miles. Your crank was spun at 500 rpm, which is the standard rpm used for balancing. On a side note, the piston is quite heavy at over 500 grams.

So the question must be asked. Woody can you weight everything and balance it in under 7 min?  Hmmmmm

Thanks. I got the kit new in the box from a guy that was needing money in a serious way. For the price of the kit I really can't complain. The car will be a weekend fun car and one that the girl will learn with at the track.

   I've always wondered how they simulate the weight of pistons and rods.  Very interesting.

Is it assumed that the crank was machined before balance, or is it common that Scat journals are in spec out of the box?
