I don't know about the rotaries, but BNR did a hybrid turbo for my old supra. It was the exact opposite of what you want for gravel. It wasn't extremely laggy but hit VERY hard when boost came on. Great for a street car, not so much for low traction events.

Right now I'm trying to decide whether an NA bridgeport is going to be too much for my rallycross car.
