Edvis Miller has one in his Duster, he was an early subscriber to them I think.

His Duster is now running in the 8.50S NA at 3200lbs or somewhere in that area. He says its on pump gas but he carries VP containers on his drag week trailer LOL.

I also think the Australians that come over for drag week are running a predator mill, 7.50s in a 4000lb+ car with twin turbos.
