Galloping ghost breakaway runner

[Taylor]

I have heard that the Galloping Ghost breakaway runner is pure speed, but I can't get any speed out of it. I have a base that runs coast to coast in 4.5 seconds. And when I put that figure on the base it takes more than 15 seconds to go coast to coast. I have tried prolines, polos, oranges, single clips, and speed diamond bases and none seem to work! I have been trying to tweak those bases for about 2 hours today and have had no luck.
How do I get a good performing base for this figure?
Help!
