The poor microphone on the camera had trouble with the noise, but it sure sounds good. This a Rototest dyno that bolts to the hubs, so there's no drama as there is with the roller type dynos. There's a wideband A/F meter on the scuttle and the main dyno computer is both datalogging everything from the ECU and of course the dyno run itself. This run was around 125 hp at the rear wheels.
